Quiz Answer Key
REST APIs often require multiple endpoints to fetch different data, while GraphQL uses a single endpoint where clients specify the exact data fields they need, making it more flexible and efficient. GraphQL minimizes over-fetching or under-fetching issues for complex applications.
Backend frameworks provide a structured foundation for building servers, handling repetitive tasks like routing and middleware. This allows developers to focus on the unique logic of their application. Examples include Express.js, Django, and Ruby on Rails.
Relational databases store data in structured tables with rows and columns and use SQL for querying and manipulating data. Non-relational databases offer more flexibility, storing unstructured or semi-structured data, and don’t rely on a rigid table structure.
You might choose NoSQL for handling large volumes of data, real-time analytics, or flexible data models, such as in social media apps, IoT devices, or big data analytics, where relationships between data points are less complex or not easily defined.
A “rate limit exceeded” message indicates that a client has made too many requests to an API within a certain time frame, which could potentially overwhelm the server. This is implemented to prevent bad actors or bots from making excessive calls that could crash the server.
A linter is a tool that analyzes source code for potential errors, bugs, and style inconsistencies. It helps developers maintain a clean and consistent codebase, making it easier to scale the application and avoid future issues.
Nodemon automatically restarts the server whenever changes are made to the codebase, this eliminates the need to manually restart the server each time a change is made, making development smoother and more efficient.
Environment variables are dynamic values that can affect the behavior of running processes. Managing them for different environments (like development and production) allows for different settings (like port numbers or database URIs) to be used without changing the underlying code.
Routes are specific paths (endpoints) in a backend application that map to specific functionalities, they define how the backend will respond to different HTTP requests (GET, POST, PUT, DELETE).
Middleware in a backend application is code that is executed in the middle of the request/response cycle. For example, the error handling middleware intercepts errors and returns useful information or the arcjet middleware protects the api against common attacks and bot traffic.

Quote: “you’ll be hit with a rate limit exceeded this means that you’ll stop bad users from making additional requests and crashing your server”
Bot Protection: It shows how to add a layer of bot protection to block malicious users or Bots from accessing your API.
Quote: “we’ll also Implement a bot protection system that will block them from accessing your API all of that using arcjet”
JSON Web Tokens (JWT): JWTs are used for user authentication. The tutorial demonstrates generating and verifying JWTs to protect API endpoints.
Password Hashing: Bcrypt is used to hash passwords, ensuring secure storage in the database.
Authorization Middleware: A custom middleware is introduced to verify user tokens and protect private routes.
Quote: “This means if at any point something goes wrong don’t do anything aboard that transaction”
Application Logic:
Controllers: It introduces the use of controller files to house the logic for handling API routes, keeping the routes files clean.
Models: Mongoose is used to create data models (schemas) for both users and subscriptions, defining data structure and validation rules. The subscription model is very comprehensive, showcasing use of validators, enums and timestamps as well as pre-save hooks and virtual fields.
CRUD Operations: The tutorial shows how to implement Create, Read, Update, and Delete (CRUD) operations for users and subscriptions.
Quote: “a foundational element of every sing s Le API out there you need to be able to delete create or read or update literally anything out there”
Error Handling: A global error handling middleware is created to manage and format responses for various types of errors, such as resource not found, duplicate keys, and validation errors, which helps with debugging.
Advanced Features:
Atomic Operations: The concept of atomic operations is introduced by making database transactions. This makes it so multiple operations can be treated as single units of work, preventing partial updates. *Quote: “database operations have to be Atomic which means that they either have to do All or Nothing insert either works completely or it doesn’t”
Upstash Workflow: The guide also introduces a system for setting up email reminders using Upstash, a platform for serverless workflows. Upstash helps set up tasks which can be triggered on a cron basis to send emails or SMS messages to a user. This also shows how to set up Upstash workflows using a local development server for testing purposes.
Email Reminders: NodeMailer is used to send reminder emails to users based on subscription renewal dates. This includes a nice custom email template with HTML.
Deployment
Virtual Private Server (VPS): The tutorial uses Hostinger VPS for deploying the API, emphasizing the flexibility and control it offers.
Git: Git is used for version control and for transferring the code to the VPS.
PM2: PM2 is used as a process manager to keep the Node.js application running reliably on the VPS. The document does note that the deployment portion may have errors as it depends on the operating system chosen for the VPS but there is a free, step by step guide included to finish the deployment.

Building and Securing GraphQL APIs
Frequently Asked Questions:
What are the advantages of using GraphQL APIs compared to REST APIs? GraphQL APIs offer greater flexibility than REST APIs by allowing clients to request the specific data they need. Unlike REST where multiple endpoints may be required for different data sets, GraphQL uses a single endpoint and clients can specify the precise fields required. This is particularly efficient for complex applications with lots of interconnected data, as it reduces over-fetching (getting more data than required) or under-fetching (not getting all the data required) of information.
What are backend frameworks and why are they essential for building APIs? Backend frameworks provide a structured foundation for building servers and APIs. They handle repetitive tasks like routing, middleware, and error handling, allowing developers to focus on the application’s specific logic. This significantly reduces the amount of code needed to start, thus accelerating the development process. Popular frameworks include Express.js, Hono, and NestJS for JavaScript; Django for Python; Ruby on Rails for Ruby; and Spring for Java.
Why are databases essential for backend development, and what are the two primary types? Databases are specialized systems designed for efficient storage, organization, and management of data, essential for the backend of an application. They are optimized for speed, security, and scalability. The two primary types are relational and non-relational databases: relational databases store data in structured tables with rows and columns, using SQL, and are best for structured data like in banking systems, while non-relational (NoSQL) databases like MongoDB offer greater flexibility for unstructured or semi-structured data, ideal for social media apps or real-time analytics.
How do relational (SQL) and non-relational (NoSQL) databases differ, and when should each be used? Relational databases (SQL) organize data into tables with rows and columns, using SQL for querying and manipulation, making them best for structured data and complex relationships, such as in banking or e-commerce. NoSQL databases, like document-based MongoDB or key-value stores like Redis, offer greater flexibility and can handle unstructured or semi-structured data. NoSQL databases are preferred when dealing with large volumes of data, real-time analytics, or flexible data models, as often seen in social media platforms, IoT devices or big data analytics.
What is rate limiting and bot protection, and why are they crucial for API security? Rate limiting is a technique used to control the number of requests a user can make within a specific time frame, preventing API spam and denial-of-service attacks. Bot protection systems identify and block malicious bot traffic, protecting the API from unauthorized access and abuse. Both are essential to maintain server stability, performance, and prevent potential system crashes due to malicious or unintended excessive use.
What is middleware, and how is it utilized in the context of a backend application? Middleware in a backend application is code that is executed before or after a request is processed by your application routes. It acts as a layer to intercept, modify, or add to the request/response cycle. Some common middleware examples are authentication middleware to check authorization levels or global error handling middleware to ensure any application errors are handled gracefully. Middleware is useful to maintain modular and reusable code, implementing functionalities like logging, authorization, or data validation and transformation.
What are JSON Web Tokens (JWTs) and how are they used in the provided system for authentication and authorization? JSON Web Tokens (JWTs) are a standard method for representing claims securely between two parties. In the provided system, JWTs are used for authentication and authorization. When a user signs up or signs in, the server generates a JWT containing the user ID and sends it back to the client. For subsequent requests to protected routes, clients include the JWT in the request header. The server then verifies the JWT, authenticating the user and determining whether they have the necessary authorization to access the route. If invalid or missing, the user will receive an unathorized error message.
What is the purpose of using a local development server for workflows, such as those developed with Upstash, and why is it beneficial? Local development servers allow you to test and debug workflows without having to deploy code to a live environment. They simulate a production-like setup, enabling you to identify and fix potential issues. This is particularly useful with tools like Upstash, where it enables unlimited tests without incurring costs associated with running the workflows. This helps reduce costs and save time from complex setups, making the development process more efficient.
Backend Development Fundamentals
Backend development is crucial for the functionality of applications, handling data, security, and performance behind the scenes. It involves servers, databases, APIs, and authentication.
Here’s a breakdown of key backend concepts:
The Web’s Two Parts: The web is divided into the front end, which focuses on user experience, and the backend, which manages data and logic.
Servers: Servers are powerful computers that store, process, and send data. They host the backend code that manages users, processes data, and interacts with databases.
Client-Server Communication: Clients (like browsers) send requests to servers. Servers process these requests and send back data.
Protocols: Computers use communication rules called protocols, with HTTP (Hypertext Transfer Protocol) as the backbone of the internet. HTTPS is the secure version of HTTP.
DNS (Domain Name System): DNS translates domain names (like google.com) into IP addresses (like 192.168.1.1), which are unique identifiers for devices on the internet.
APIs (Application Programming Interfaces): APIs allow applications to communicate with the backend. They define how clients and servers interact by using HTTP methods to define actions, endpoints (URLs for specific resources), headers (metadata), request bodies (data sent to the server), and response bodies (data sent back).
HTTP Methods/Verbs: APIs use HTTP methods like GET (retrieve data), POST (create new data), PUT/PATCH (update data), and DELETE (remove data).
API Endpoints: A URL that represents a specific resource or action on the backend.
Status Codes: API calls use status codes to indicate what happened, such as 200 (OK), 201 (created), 400 (bad request), 404 (not found), and 500 (internal server error).
RESTful APIs: REST (Representational State Transfer) APIs are structured, stateless, and use standard HTTP methods, making them widely used for web development.
GraphQL APIs: GraphQL APIs, developed by Facebook, allow clients to request specific data, reducing over-fetching and under-fetching, which makes them efficient for complex applications.
Backend Languages: Languages like Python, Ruby, Java, and JavaScript (with runtimes like Node.js) can be used to build APIs.
Backend Frameworks: Frameworks like Express.js (for JavaScript), Django (for Python), Ruby on Rails (for Ruby), and Spring (for Java) provide a structured foundation for building servers, handling routing, middleware, and errors, allowing developers to focus on the app’s logic.
Databases are crucial for storing, organizing, and managing data, optimized for speed, security, and scalability. They are classified into two main types:
Relational Databases: These store data in tables with rows and columns and use SQL (Structured Query Language) to query and manipulate data (e.g., MySQL, PostgreSQL). They are suitable for structured data with clear relationships.
Non-Relational Databases (NoSQL): These databases offer more flexibility, handling unstructured or semi-structured data (e.g., MongoDB, Redis). They are useful for large data volumes, real-time analytics, or flexible data models.
ORM (Object-Relational Mappers): ORMs simplify database interactions by allowing queries to be written in the syntax of the chosen programming language, instead of raw SQL.
Backend Architectures:
Monolithic Architecture: All application components are combined into a single codebase. It’s simple to develop and deploy but can become difficult to scale.
Microservices Architecture: An application is broken down into independent services communicating via APIs. This is good for large-scale applications requiring flexibility and scalability.
Serverless Architecture: Allows developers to write code without managing the underlying infrastructure. Cloud providers manage provisioning, scaling, and server management.
Other important concepts include:
Authentication: Securing applications by verifying user identity and using techniques like JWTs (JSON Web Tokens) to authenticate users.
Authorization: Managing access to resources based on the user’s role or permissions.
Middleware: Functions that intercept requests, allowing for actions like error handling, authorization, and rate limiting.
Rate Limiting: Restricting the number of requests a user can make within a given time frame, preventing server overload or abuse.
Bot Protection: Techniques that detect and block automated traffic from malicious bots.
In summary, backend development involves creating the logic and infrastructure that power applications, handling data storage, user authentication, and ensuring smooth performance.
Subscription System Backend Development
A subscription system, as discussed in the sources, involves several key components related to backend development:
Core Functionality: The primary goal of a subscription system is to manage users, their subscriptions, and related business logic, including handling real money.
Backend Focus: The backend handles all the logic, from processing data to managing users and interacting with databases, while the front end is focused on the user interface.
Subscription Tracking API: This API is built to manage subscriptions, handle user authentication, manage data, and automate email reminders. It includes functionalities such as:
User Authentication: Using JSON Web Tokens (JWTs) to authenticate users.
Database Modeling and Relationships: Utilizing databases like MongoDB and Mongoose to model data.
CRUD Operations: Performing create, read, update, and delete operations on user and subscription data.
Subscription Management: Managing subscription lifecycles, including calculating renewal dates and sending reminders.
Global Error Handling: Implementing middleware for input validation, error logging, and debugging.
Rate Limiting and Bot Protection: Securing the API with tools like Arcjet to prevent abuse.
Automated Email Reminders: Using services like Upstash to schedule email notifications for subscription renewals.
API Endpoints: These are specific URLs that handle different actions related to subscriptions. Examples include:
GET /subscriptions: Retrieves all subscriptions.
GET /subscriptions/:id: Retrieves details of a specific subscription.
POST /subscriptions: Creates a new subscription.
PUT /subscriptions/:id: Updates an existing subscription.
DELETE /subscriptions/:id: Deletes a subscription.
GET /subscriptions/user/:id: Retrieves all subscriptions for a specific user.
PUT /subscriptions/:id/cancel: Cancels a user subscription.
GET /subscriptions/renewals: Retrieves all upcoming renewals.
Data Validation: Ensuring that the data sent to the backend is correct, for example, by using validation middleware to catch any errors.
Database Interaction: Using queries to store, retrieve, update, and delete data in the database. Object-relational mappers (ORMs) like Mongoose are used to simplify these interactions.
Workflows: Automating tasks using systems like Upstash, particularly for scheduling notifications or other business logic. This includes:
Triggering workflows when a new subscription is created.
Retrieving subscription details from the database.
Checking the subscription status and renewal date.
Scheduling email reminders before the renewal date.
Email Reminders: The system sends automated email reminders for upcoming subscription payments, allowing users to cancel subscriptions on time.
Deployment: The subscription system can be deployed to a virtual private server (VPS) for better performance, control, and customization. This requires server management, database backups, and real-world deployment skills.
Security: Includes measures to protect the system from abuse such as rate limiting and bot protection.
In summary, a subscription system involves building a comprehensive backend infrastructure that handles user authentication, manages subscription data, ensures data integrity, and automates notifications, all while providing a secure and scalable environment.
Database Management in Backend Development
Database management is a critical aspect of backend development, involving the storage, organization, and management of data. Databases are optimized for speed, security, and scalability and are essential for applications to function effectively. The sources discuss key aspects of database management, including types of databases, how applications interact with them, and methods to manage data efficiently:
Types of Databases:
Relational Databases (SQL): These databases store data in structured tables with rows and columns. They use SQL (Structured Query Language) for querying and manipulating data. Relational databases are suitable for structured data with clear relationships and are often used in banking, e-commerce, and inventory management. Popular examples include MySQL and PostgreSQL.
Non-Relational Databases (NoSQL): These databases offer more flexibility and do not rely on a rigid table structure. They are designed to handle unstructured or semi-structured data, making them suitable for social media apps, IoT devices, and big data analytics. NoSQL databases include document-based databases like MongoDB, which store data in JSON-like documents, and key-value pair databases like Redis.
Database Interactions:
Client-Server Communication: The client sends a request to the backend, which processes the request and determines what data is needed.
Queries: The backend sends queries to the database to fetch, update, or delete data. In SQL databases, queries use SQL syntax, while in NoSQL databases like MongoDB, queries are often similar to JavaScript syntax.
Data Retrieval: The database returns the requested data to the server, which then formats it (usually as JSON) and sends it back to the client.
Data Management:
CRUD Operations: Databases support CRUD (Create, Read, Update, Delete) operations, which are fundamental for managing resources.
Raw Queries: Developers can write raw queries to interact with the database, offering full control but potentially increasing complexity and errors.
ORMs (Object-Relational Mappers): ORMs simplify database interactions by allowing developers to write queries in the syntax of their chosen programming language instead of raw SQL. Popular ORMs include Prisma and Drizzle for SQL databases and Mongoose for MongoDB. ORMs speed up development and help prevent errors.
Database Selection:
Structured vs. Unstructured Data: The choice between relational and non-relational databases depends on the type of data and the application’s needs. Relational databases are best for structured data with clear relationships, while non-relational databases are suitable for massive, unstructured data and flexible data models.
Database Modeling:
Schemas: Databases utilize schemas to define the structure of data.
Models: Models are created from the schema to create instances of the data structure, for example, User or Subscription.
Key Considerations:
Speed: Databases are optimized for fast data retrieval and storage.
Security: Databases implement security measures to protect data.
Scalability: Databases are designed to handle growing amounts of data and user traffic.
MongoDB:
MongoDB Atlas: A cloud-based service that allows for easy creation and hosting of MongoDB databases, including free options.
Mongoose: An ORM used with MongoDB to create database models and schemas. Mongoose also simplifies data validation and other model-level operations.
In summary, effective database management involves choosing the right type of database for the application’s needs, using efficient methods to interact with the database, and ensuring that data is stored, retrieved, and managed securely and scalably. The use of ORMs can significantly simplify these processes, allowing developers to focus on application logic rather than low-level database operations.
API Development Fundamentals
API (Application Programming Interface) development is a crucial part of backend development, facilitating communication between different software systems. APIs define the rules and protocols that allow applications to interact with each other, enabling the exchange of data and functionality. The sources provide a detailed overview of API development, covering key concepts, components, types, and best practices:
Fundamentals of APIs:
Definition: An API is an interface that enables different applications to communicate and exchange data. It acts like a “waiter” that takes requests from the client (e.g., a web app or mobile app) to the backend (the “kitchen”) and returns the requested data.
Client-Server Communication: APIs facilitate how clients and servers communicate, using protocols such as HTTP.
Function: APIs enable apps to fetch new data, manage resources, and perform actions on the backend.
Key Components of APIs:
HTTP Methods (Verbs): These methods define the type of action to be taken on a resource.
GET: Retrieves data from the server. For example, GET /users to get a list of users.
POST: Creates a new resource on the server. For example, POST /users to create a new user.
PUT/PATCH: Updates an existing resource. For example, PUT /users/:id to update a specific user.
DELETE: Removes a resource from the server. For example, DELETE /users/:id to delete a specific user.
Endpoints: These are URLs that specify a particular resource or action on the backend. For example, /users, /subscriptions and /auth/signup.
Headers: Headers contain metadata about the request or response, such as authentication tokens, content type, or caching instructions. For example, an authorization header often includes a bearer token for verifying the user’s identity.
Request Body: The request body contains the data being sent to the server, usually in JSON format. This is used in POST and PUT requests.
Response Body: The response body contains the data sent back by the server after processing the request, typically also in JSON format.
Status Codes: These codes indicate the outcome of an API call.
200 (OK): Indicates a successful request.
201 (Created): Indicates a resource has been successfully created.
400 (Bad Request): Indicates something went wrong with the request.
404 (Not Found): Indicates that the requested resource does not exist.
401 (Unauthorized): Indicates that the user does not have permission to access the resource.
500 (Internal Server Error): Indicates a server-side error.
API Design:
Naming Conventions: Use nouns in URLs to specify resources and HTTP verbs to specify actions. For example, use /users instead of /getUsers. Use plural nouns for resources, and use hyphens to connect words together in URLs.
RESTful Principles: Follow the principles of RESTful architecture which is the most common thing that you will see in web development, for example, use standard HTTP methods like GET, POST, PUT, and DELETE and maintain statelessness of requests.
Types of APIs:
RESTful APIs: These are the most common type of APIs, following a structured approach where clients interact with resources via URLs and standard HTTP methods. RESTful APIs are stateless and typically use JSON.
GraphQL APIs: These APIs offer more flexibility by allowing clients to request only the data they need via a single endpoint, which avoids over-fetching or under-fetching data. This approach is beneficial for complex applications.
API Development Process:
Backend Language: Use languages such as Python, Ruby, Java, or JavaScript runtimes like Node, Bun, or Deno.
Backend Frameworks: Utilize frameworks like Express (for JavaScript), Django (for Python), Ruby on Rails (for Ruby), or Spring (for Java) to provide a structured foundation for building servers and handling repetitive tasks such as routing, middleware, and error handling.
Database Management: Connect your API to a database to store and retrieve data, using either raw queries or ORMs.
Middleware: Implement middleware for input validation, error handling, authentication, rate limiting and bot protection.
Security: Implement security measures such as authorization and protection from malicious users.
Authorization: Ensure only authorized users can access certain routes by verifying tokens included in requests.
Rate Limiting: Restrict the number of requests a user can make within a specific period to prevent abuse.
Bot Protection: Implement systems to detect and block bot traffic.
Example API Endpoints:
/api/v1/auth/signup (POST): Creates a new user.
/api/v1/auth/signin (POST): Signs in an existing user.
/api/v1/users (GET): Retrieves a list of users.
/api/v1/users/:id (GET): Retrieves a specific user by ID.
/api/v1/subscriptions (GET): Retrieves all subscriptions.
/api/v1/subscriptions (POST): Creates a new subscription.
/api/v1/subscriptions/user/:id (GET): Retrieves subscriptions of a specific user.
Testing APIs:
Use tools like HTTP clients (e.g., HTTPie, Postman, Insomnia, Bruno) to test API endpoints and simulate requests.
Test with different HTTP methods and request bodies to ensure correct functionality.
In summary, API development involves designing and building interfaces that allow applications to communicate effectively. This includes defining endpoints, choosing HTTP methods, structuring request and response bodies, handling errors, and implementing security measures. The use of backend frameworks and adherence to best practices ensure that APIs are scalable, maintainable, and secure.
Backend Application Server Deployment
Server deployment is a critical step in making a backend application accessible to users. It involves setting up the necessary infrastructure and configurations to host the application, making it available over the internet. The sources provide key insights into server deployment, covering essential aspects such as types of servers, deployment processes, and tools involved:
Types of Servers:
Physical Servers: These are actual machines in data centers that you can own or rent.
Virtual Private Servers (VPS): A VPS is like having your own computer in the cloud, offering dedicated resources, full control, and customization without the high cost of a physical machine. VPS hosting is suitable for deploying APIs, full-sta
ck applications, databases, and other server-side applications.
Cloud Servers: Cloud providers such as AWS provide servers that can be rented and configured through their services.
Serverless Architecture: This allows developers to write code without managing the underlying infrastructure, with cloud providers handling provisioning, scaling, and server management.
Deployment Process:
Setting up the Server: This involves configuring the server’s operating system (often Linux) and installing necessary software, such as Node.js, npm, and Git.
Transferring Codebase: Use Git to transfer your application’s code from your local development environment to the server. This usually involves pushing code to a repository and cloning it on the server.
Installing Dependencies: Install all the application’s dependencies on the server using a package manager like npm.
Configuring Environment Variables: Set up environment variables on the server to handle different environments such as development, staging, or production. This involves adding environment variables for databases, API keys, and other sensitive information.
Running the Application: Use a process manager like pm2 to ensure that the application runs continuously, even if it crashes or the server reboots. A process manager also allows for background execution.
Testing: After deploying the server, testing API endpoints through HTTP clients is essential to ensure the deployed application functions as expected.
Key Considerations for VPS Hosting:
Dedicated Resources: A VPS provides dedicated RAM and SSD storage for better performance.
Full Control: You have full control and customization over your server, allowing you to run applications as desired.
Real-World Skills: Hosting on a VPS provides hands-on experience with server management, database backup, and real-world deployments.
Cost-Effective: VPS hosting is a cost-effective alternative to physical servers and provides better performance than regular shared hosting.
Tools and Technologies
Git: A version control system for managing and transferring code.
npm: A package manager used for installing packages, libraries, and tools needed for Node.js applications.
pm2: A process manager for Node.js applications that ensures applications keep running.
SSH: Secure Shell Protocol is used to remotely manage the server through a terminal.
Operating System: Linux, like Ubuntu, is often the preferred choice for hosting servers.
Deployment Workflow
Development: Develop the application on a local machine using a code editor or IDE.
Testing: Test the application locally to ensure all features work as expected before deploying.
Code Transfer: Use Git to upload the code to a repository like GitHub, and then clone the repository to the VPS.
Environment Setup: Configure all necessary environment variables on the server.
Dependency Installation: Install all the required packages using npm install.
Application Execution: Run the application using pm2 to start the process and keep it running in the background.
Monitoring: Regularly monitor the server to ensure optimal performance and identify any potential issues.
In summary, server deployment is a crucial process for making a backend application accessible to users. It involves setting up a server (physical, virtual, or serverless), transferring the codebase, installing dependencies, configuring the environment, and running the application. VPS hosting offers dedicated resources, full control, and real-world deployment skills, making it a valuable option for deploying backend applications. Following best practices and using the right tools will ensure a smooth and successful deployment process.

What does the stack function do to tensors and how is it different from unsqueeze? The stack function concatenates a sequence of tensors along a new dimension, increasing the dimensions of the tensor by one. The unsqueeze adds a single dimension to a target tensor at a specified dimension.
What does the term “device agnostic code” mean, and why is it important in PyTorch? Device-agnostic code in PyTorch means writing code that can run on either a CPU or GPU without modification. This is important for portability and leveraging the power of GPUs when available.
In PyTorch, what is a “parameter”, how is it created, and what special property does it have? A “parameter” is a special type of tensor created using nn.parameter that is a module attribute. When assigned as a module attribute, parameters are automatically added to a module’s parameter list, enabling gradient tracking during training.
Explain the primary difference between the training loop and the testing/evaluation loop in a neural network. The training loop involves the forward pass, loss calculation, backpropagation and updating the model’s parameters through optimization, whereas the testing/evaluation loop involves only the forward pass and loss and/or accuracy calculation without gradient calculation and parameter updates.

PyTorch Deep Learning Fundamentals
Okay, here’s a detailed briefing document summarizing the key themes and ideas from the provided source, with relevant quotes included:
Briefing Document: PyTorch Deep Learning Fundamentals
Introduction:
This document summarizes the core concepts and practical implementations of PyTorch for deep learning, as detailed in the provided course excerpts. The focus is on tensors, their properties, manipulations, and usage within the context of neural network building and training.
I. Tensors: The Building Blocks
Definition: Tensors are the fundamental data structure in PyTorch, used to encode data as numbers. Traditional terms like scalars, vectors, and matrices are all represented as tensors in PyTorch.
“basically anytime you encode data into numbers, it’s of a tensor data type.”
Scalars: A single number.
“A single number, number of dimensions, zero.”
Vectors: Have magnitude and direction and typically have more than one number.
“a vector typically has more than one number”
“a number with direction, number of dimensions, one”
Matrices: Two-dimensional tensors.
“a matrix, a tensor.”
Dimensions (ndim): Represented by the number of square bracket pairings in the tensor’s definition.
“dimension is like number of square brackets…number of pairs of closing square brackets.”
Shape: Defines the size of each dimension in a tensor.
For example, a vector [1, 2] has a shape of (2,) or (2,1). A matrix [[1, 2], [3, 4]] has a shape of (2, 2).
“the shape of the vector is two. So we have two by one elements.”
Data Type (dtype): Tensors have a data type (e.g., float32, float16, int32, long). The default dtype in PyTorch is float32.
“the default data type in pytorch, even if it’s specified as none is going to come out as float 32.”
It’s important to ensure tensors have compatible data types when performing operations to avoid errors.
Device: Tensors can reside on different devices, such as the CPU or GPU (CUDA). Device-agnostic code is recommended to handle this.
II. Tensor Creation and Manipulation
Creation:torch.tensor(): Creates tensors from lists or NumPy arrays.
torch.zeros(): Creates a tensor filled with zeros.
torch.ones(): Creates a tensor filled with ones.
torch.arange(): Creates a 1D tensor with a range of values.
torch.rand(): Creates a tensor with random values.
torch.randn(): Creates a tensor with random values from normal distribution.
torch.zeros_like()/torch.ones_like()/torch.rand_like(): Creates tensors with the same shape as another tensor.
Indexing: Tensors can be accessed via numerical indices, allowing one to extract elements or subsets.
“This is where the square brackets, the pairings come into play.”
Reshaping:reshape(): Changes the shape of a tensor, provided the total number of elements remains the same.
view(): Creates a view of the tensor, sharing the same memory, but does not change the shape of the original tensor. Modifying a view changes the original tensor.
Stacking: torch.stack() concatenates tensors along a new dimension. torch.vstack() and torch.hstack() are similar along specific axes.
Squeezing and Unsqueezing: squeeze() removes dimensions of size 1, and unsqueeze() adds dimensions of size 1.
Element-wise operations: standard operations like +, -, *, / are applied element-wise.
If reassigning the tensor variable (e.g., tensor = tensor * 10), the original tensor will be changed.
Matrix Multiplication: Use @ operator (or .matmul() function). Inner dimensions must match for valid matrix multiplication.
“inner dimensions must match.”
Transpose: tensor.T will tranpose a tensor (swap rows/columns)
Aggregation: Functions like torch.min(), torch.max(), torch.mean(), and their respective index finders like torch.argmin()/torch.argmax() reduce the tensor to scalar values.
“So you’re turning it from nine elements to one element, hence aggregation.”
Attributes: tensors have attributes like dtype, shape (or size), and can be retrieved with tensor.dtype or tensor.shape (or tensor.size())
III. Neural Networks with PyTorch
torch.nn Module: The module provides building blocks for creating neural networks.
“nn is the building block layer for neural networks.”
nn.Module: The base class for all neural network modules. Custom models should inherit from this class.
Linear Layers (nn.Linear): Represents a linear transformation (y = Wx + b).
Activation Functions: Non-linear functions such as ReLU (Rectified Linear Unit) and Sigmoid, enable neural networks to learn complex patterns.
“one divided by one plus torch exponential of negative x.”
Parameter (nn.Parameter): A special type of tensor that is added to a module’s parameter list, allowing automatic gradient tracking
“Parameters are torch tensor subclasses…automatically added to the list of its parameters.”
It’s critical to set requires_grad=True for parameters that need to be optimized during training.
Sequential Container (nn.Sequential): A convenient way to create models by stacking layers in a sequence.
Forward Pass: The computation of the model’s output given the input data. This is implemented in the forward() method of a class inheriting from nn.Module.
“Do the forward pass.”
Loss Functions: Measure the difference between the predicted and actual values.
“Calculate the loss.”
Optimizers: Algorithms that update the model’s parameters based on the loss function during training (e.g., torch.optim.SGD).
“optimise a step, step, step.”
Use optimizer.zero_grad() to reset the gradients before each training step.
Training Loop: The iterative process of:
Forward pass
Calculate Loss
Optimizer zero grad
Loss backwards
Optimizer Step
Evaluation Mode: Set the model to model.eval() before doing inference (testing/evaluation), and it sets requires_grad=False
IV. Data Handling

Device Agnostic Data: Send data to the appropriate device (CPU/GPU) using .to(device)
NumPy Interoperability: PyTorch can handle NumPy arrays with torch.from_numpy(), but the data type needs to be changed to torch.float32 from float64
V. Visualization
Matplotlib: Library is used for visualizing plots and images.
“Our data explorers motto is visualize, visualize, visualize.”
plt.imshow(): Displays images.
plt.plot(): Displays data in a line plot.
VI. Key Practices
Visualize, Visualize, Visualize: Emphasized for data exploration.
Device-Agnostic Code: Aim to write code that can run on both CPU and GPU.
Typo Avoidance: Be careful to avoid typos as they can cause errors.
VII. Specific Examples/Concepts Highlighted:
Image data: tensors are often (height, width, color_channels) or (batch_size, color_channels, height, width)
Linear regression: the formula y=weight * x + bias
Non linear transformations: using activation functions to introduce non-linearity
Multi-class data sets: Using make_blobs function to generate multiple data classes.
Convolutional layers (nn.Conv2d): For processing images, which require specific parameters like in-channels, out-channels, kernel size, stride, and padding.
Flatten layer (nn.Flatten): Used to flatten the input into a vector before a linear layer.
Data Loaders: Batches of data in an iterable for training or evaluation loops.
Conclusion:
This document provides a foundation for understanding the essential elements of PyTorch for deep learning. It highlights the importance of tensors, their manipulation, and their role in building and training neural networks. Key concepts such as the training loop, device-agnostic coding, and the value of visualization are also emphasized.
This briefing should serve as a useful reference for anyone learning PyTorch and deep learning fundamentals from these course materials.
PyTorch Fundamentals: Tensors and Neural Networks
1. What is a tensor in PyTorch and how does it relate to scalars, vectors, and matrices?
In PyTorch, a tensor is the fundamental data structure used to represent data. Think of it as a generalization of scalars, vectors, and matrices. A scalar is a single number (0 dimensions), a vector has magnitude and direction, and is represented by one dimension, while a matrix has two dimensions. Tensors can have any number of dimensions and can store numerical data of various types. In essence, when you encode any kind of data into numbers within PyTorch, it becomes a tensor. PyTorch uses the term tensor to refer to any of these data types.
2. How are the dimensions and shape of a tensor determined?
The dimension of a tensor can be determined by the number of square bracket pairs used to define it. For example, [1, 2, 3] is a vector with one dimension (one pair of square brackets), and [[1, 2], [3, 4]] is a matrix with two dimensions (two pairs). The shape of a tensor refers to the size of each dimension. For instance, [1, 2, 3] has a shape of (3), meaning 3 elements in the first dimension, while [[1, 2], [3, 4]] has a shape of (2, 2), meaning 2 rows and 2 columns. Note: The shape is determined by the number of elements in each dimension.
3. How do you create tensors with specific values in PyTorch?
PyTorch provides various functions to create tensors:
torch.tensor([value1, value2, …]) directly creates a tensor from a Python list. You can control the data type (dtype) of the tensor during its creation by passing the dtype argument.
torch.zeros(size) creates a tensor filled with zeros of the specified size.
torch.ones(size) creates a tensor filled with ones of the specified size.
torch.rand(size) creates a tensor filled with random values from a uniform distribution (between 0 and 1) of the specified size.
torch.arange(start, end, step) creates a 1D tensor containing values from start to end (exclusive), incrementing by step.
torch.zeros_like(other_tensor) and torch.ones_like(other_tensor) create tensors with the same shape and dtype as the other_tensor, filled with zeros or ones respectively.
4. What is the importance of data types (dtypes) in tensors, and how can they be changed?
Data types determine how data is stored in memory, which has implications for precision and memory usage. The default data type in PyTorch is torch.float32. To change a tensor’s data type, you can use the .type() method, e.g. tensor.type(torch.float16) will convert a tensor to 16 bit float. While PyTorch can often automatically handle operations between different data types, using the correct data type can prevent unexpected errors or behaviors. It’s good to be explicit.
5. What are tensor attributes such as shape, size, and Dtype and how do they relate to tensor manipulation?
These are attributes that can be used to understand, manipulate, and diagnose issues with tensors.
Shape: An attribute that represents the dimensions of the tensor. For example, a matrix might have a shape of (3, 4), indicating it has 3 rows and 4 columns. You can access this information by using .shape
Size: Acts like .shape but is a method i.e. .size(). It will return the dimensions of the tensor.
Dtype: Stands for data type. This defines the way the data is stored and impacts precision and memory use. You can access this by using .dtype.
These attributes can be used to diagnose issues, for example you might want to ensure all tensors have compatible data types and dimensions for multiplication.
6. How do operations like reshape, view, stack, unsqueeze, and squeeze modify the shape of tensors?
reshape(new_shape): Changes the shape of a tensor to a new shape, as long as the total number of elements remains the same, a tensor with 9 elements can be reshaped into (3, 3) or (9, 1) for example.
view(new_shape): Similar to reshape, but it can only be used to change the dimensions of a contiguous tensor (a tensor that has elements in continuous memory) and will also share the same memory as the original tensor meaning changes will impact each other.
stack(tensors, dim): Concatenates multiple tensors along a new dimension (specified by dim) and increases the overall dimensionality by 1.
unsqueeze(dim): Inserts a new dimension of size one at a specified position, increasing the overall dimensionality by 1.
squeeze(): Removes all dimensions with size one in a tensor, reducing overall dimensionality of a tensor.
7. What are the key components of a basic neural network training loop?
The key components include:
Forward Pass: The input data goes through the model, producing the output.
Calculate Loss: The error is calculated by comparing the output to the true labels.
Zero Gradients: Previous gradients are cleared before starting a new iteration to prevent accumulating them across iterations.
Backward Pass: The error is backpropagated through the network to calculate gradients.
Optimize Step: The model’s parameters are updated based on the gradients using an optimizer.
Testing / Validation Step: The model’s performance is evaluated against a test or validation dataset.
8. What is the purpose of torch.nn.Module and torch.nn.Parameter in PyTorch?
torch.nn.Module is a base class for creating neural network models. Modules provide a way to organize and group layers and functions, such as linear layers, activation functions, and other model components. It keeps track of learnable parameters.
torch.nn.Parameter is a special subclass of torch.Tensor that is used to represent the learnable parameters of a model. When parameters are assigned as module attributes, PyTorch automatically registers them for gradient tracking and optimization. It tracks gradient when ‘requires_grad’ is set to true. Setting requires_grad=True on parameters tells PyTorch to calculate and store gradients for them during backpropagation.
PyTorch: A Deep Learning Framework
PyTorch is a machine learning framework written in Python that is used for deep learning and other machine learning tasks [1]. The framework is popular for research and allows users to write fast deep learning code that can be accelerated by GPUs [2, 3].
Key aspects of PyTorch include:
Tensors: PyTorch uses tensors as a fundamental building block for numerical data representation. These can be of various types, and neural networks perform mathematical operations on them [4, 5].
Neural Networks: PyTorch is often used for building neural networks, including fully connected and convolutional neural networks [6]. These networks are constructed using layers from the torch.nn module [7].
GPU Acceleration: PyTorch can leverage GPUs via CUDA to accelerate machine learning code. GPUs are fast at numerical calculations, which are very important in deep learning [8-10].
Flexibility: The framework allows for customization, and users can combine layers in different ways to build various kinds of neural networks [6, 11].
Popularity: PyTorch is a popular research machine learning framework, with 58% of papers with code implemented using PyTorch [2, 12, 13]. It is used by major organizations such as Tesla, OpenAI, Facebook, and Microsoft [14-16].
The typical workflow when using PyTorch for deep learning includes:
Data Preparation: The first step is getting the data ready, which can involve numerical encoding, turning the data into tensors, and loading the data [17-19].
Model Building: PyTorch models are built using the nn.Module class as a base and defining the forward computation [20-23]. This includes choosing appropriate layers and defining their interconnections [11].
Model Fitting: The model is fitted to the data using an optimization loop and a loss function [19]. This involves calculating gradients using back propagation and updating model parameters using gradient descent [24-27].
Model Evaluation: Model performance is evaluated by measuring how well the model performs on unseen data, using metrics such as accuracy and loss [28].
Saving and Loading: Trained models can be saved and reloaded using the torch.save, torch.load, and torch.nn.Module.load_state_dict functions [29, 30].
Some additional notes on PyTorch include:
Reproducibility: Randomness is important in neural networks; it’s necessary to set random seeds to ensure reproducibility of experiments [31, 32].
Device Agnostic Code: It’s useful to write device agnostic code, which means code that can run on either a CPU or a GPU [33, 34].
Integration: PyTorch integrates well with other libraries, such as NumPy, which is useful for pre-processing and other numerical tasks [35, 36].
Documentation: The PyTorch website and documentation serve as the primary resource for learning about the framework [2, 37, 38].
Community Support: Online forums and communities provide places to ask questions and share code [38-40].
Overall, PyTorch is a very popular and powerful tool for deep learning and machine learning [2, 12, 13]. It provides tools to enable users to build, train, and deploy neural networks with ease [3, 16, 41].
Understanding Machine Learning Models
Machine learning models learn patterns from data, which is converted into numerical representations, and then use these patterns to make predictions or classifications [1-4]. The models are built using code and math [1].
Here are some key aspects of machine learning models based on the sources:
Data Transformation: Machine learning models require data to be converted into numbers, a process sometimes called numerical encoding [1-4]. This can include images, text, tables of numbers, audio files, or any other type of data [1].
Pattern Recognition: After data is converted to numbers, machine learning models use algorithms to find patterns in that data [1, 3-5]. These patterns can be complex and are often not interpretable by humans [6, 7]. The models can learn patterns through code, using algorithms to find the relationships in the numerical data [5].
Traditional Programming vs. Machine Learning: In traditional programming, rules are hand-written to manipulate input data and produce desired outputs [8]. In contrast, machine learning algorithms learn these rules from data [9, 10].
Supervised Learning: Many machine learning algorithms use supervised learning. This involves providing input data along with corresponding output data (features and labels), and then the algorithm learns the relationships between the inputs and outputs [9].
Parameters: Machine learning models learn parameters that represent the patterns in the data [6, 11]. Parameters are values that the model sets itself [12]. These are often numerical and can be large, sometimes numbering in the millions or even trillions [6].
Explainability: The patterns learned by a deep learning model are often uninterpretable by a human [6]. Sometimes, these patterns are lists of numbers in the millions, which is difficult for a person to understand [6, 7].
Model Evaluation: The performance of a machine learning model can be evaluated by making predictions and comparing those predictions to known labels or targets [13-15]. The goal of training a model is to move from some unknown parameters to a better, known representation of the data [16]. The loss function is used to measure how wrong a model’s predictions are compared to the ideal predictions [17].
Model Types: Machine learning models include:
Linear Regression: Models which use a linear formula to draw patterns in data [18]. These models use parameters such as weights and biases to perform forward computation [18].
Neural Networks: Neural networks are the foundation of deep learning [19]. These are typically used for unstructured data such as images [19, 20]. They use a combination of linear and non-linear functions to draw patterns in data [21-23].
Convolutional Neural Networks (CNNs): These are a type of neural network often used for computer vision tasks [19, 24]. They process images through a series of layers, identifying spatial features in the data [25].
Gradient Boosted Machines: Algorithms such as XGBoost are often used for structured data [26].
Use Cases: Machine learning can be applied to virtually any problem where data can be converted into numbers and patterns can be found [3, 4]. However, simple rule-based systems are preferred if they can solve a problem, and machine learning should not be used simply because it can [5, 27]. Machine learning is useful for complex problems with long lists of rules [28, 29].
Model Training: The training process is iterative and involves multiple steps, and it can also be seen as an experimental process [30, 31]. In each step, the machine learning model is used to make predictions and its parameters are adjusted to minimize error [13, 32].
In summary, machine learning models are algorithms that can learn patterns from data by converting the data into numbers, using various algorithms, and adjusting parameters to improve performance. Models are typically evaluated against known data with a loss function, and there are many types of models and use cases depending on the type of problem [6, 9-11, 13, 32].
Understanding Neural Networks
Neural networks are a type of machine learning model inspired by the structure of the human brain [1]. They are comprised of interconnected nodes, or neurons, organized in layers, and they are used to identify patterns in data [1-3].
Here are some key concepts for understanding neural networks:
Structure:
Layers: Neural networks are made of layers, including an input layer, one or more hidden layers, and an output layer [1, 2]. The ‘deep’ in deep learning comes from having multiple hidden layers [1, 4].
Nodes/Neurons: Each layer is composed of nodes or neurons [4, 5]. Each node performs a mathematical operation on the input it receives.
Connections: Nodes in adjacent layers are connected, and these connections have associated weights that are adjusted during the learning process [6].
Architecture: The arrangement of layers and connections determines the neural network’s architecture [7].
Function:
Forward Pass: In a forward pass, input data is passed through the network, layer by layer [8]. Each layer performs mathematical operations on the input, using linear and non-linear functions [5, 9].
Mathematical Operations: Each layer is typically a combination of linear (straight line) and nonlinear (non-straight line) functions [9].
Nonlinearity: Nonlinear functions, such as ReLU or sigmoid, are critical for enabling the network to learn complex patterns [9-11].
Representation Learning: The network learns a representation of the input data by manipulating patterns and features through its layers [6, 12]. This representation is also called a weight matrix or weight tensor [13].
Output: The output of the network is a representation of the learned patterns, which can be converted into a human-understandable format [12-14].
Learning Process:
Random Initialization: Neural networks start with random numbers as parameters, and they adjust those numbers to better represent the data [15, 16].
Loss Function: A loss function is used to measure how wrong the model’s predictions are compared to ideal predictions [17-19].
Backpropagation: Backpropagation is an algorithm that calculates the gradients of the loss with respect to the model’s parameters [20].
Gradient Descent: Gradient descent is an optimization algorithm used to update model parameters to minimize the loss function [20, 21].
Types of Neural Networks:
Fully Connected Neural Networks: These networks have connections between all nodes in adjacent layers [1, 22].
Convolutional Neural Networks (CNNs): CNNs are particularly useful for processing images and other visual data, and they use convolutional layers to identify spatial features [1, 23, 24].
Recurrent Neural Networks (RNNs): These are often used for sequence data [1, 25].
Transformers: Transformers have become popular in recent years and are used in natural language processing and other applications [1, 25, 26].
Customization: Neural networks are highly customizable, and they can be designed in many different ways [4, 25, 27]. The specific architecture and layers used are often tailored to the specific problem at hand [22, 24, 26-28].
Neural networks are a core component of deep learning, and they can be applied to a wide range of problems including image recognition, natural language processing, and many others [22, 23, 25, 26]. The key to using neural networks effectively is to convert data into a numerical representation, design a network that can learn patterns from the data, and use optimization techniques to train the model.
Machine Learning Model Training
The model training process in machine learning involves using algorithms to adjust a model’s parameters so it can learn patterns from data and make accurate predictions [1, 2]. Here’s an overview of the key steps in training a model, according to the sources:
Initialization: The process begins with a model that has randomly assigned parameters, such as weights and biases [1, 3]. These parameters are what the model adjusts during training [4, 5].
Data Input: The training process requires input data to be passed through the model [1]. The data is typically split into a training set for learning and a test set for evaluation [6].
Forward Pass: Input data is passed through the model, layer by layer [7]. Each layer performs mathematical operations on the input, which may include both linear and nonlinear functions [8]. This forward computation produces a prediction, called the model’s output or sometimes logits [9, 10].
Loss Calculation: A loss function is used to measure how wrong the model’s predictions are compared to the ideal outputs [4, 11]. The loss function provides a numerical value that represents the error or deviation of the model’s predictions from the actual values [12]. The goal of the training process is to minimize this loss [12, 13].
Backpropagation: After the loss is calculated, the backpropagation algorithm computes the gradients of the loss with respect to the model’s parameters [2, 14, 15]. Gradients indicate the direction and magnitude of the change needed to reduce the loss [1].
Optimization: An optimizer uses the calculated gradients to update the model’s parameters [4, 11, 16]. Gradient descent is a commonly used optimization algorithm that adjusts the parameters to minimize the loss [1, 2, 15]. The learning rate is a hyperparameter that determines the size of the adjustments [5, 17].
Training Loop: The process of forward pass, loss calculation, backpropagation, and optimization is repeated iteratively through a training loop [11, 17, 18]. The training loop is where the model learns patterns on the training data [19]. Each iteration of the loop is called an epoch [20].
Evaluation: After training, the model’s performance is evaluated on a separate test data set [19]. This evaluation helps to measure how well the model has learned and whether it can generalize to unseen data [21].
In PyTorch, the training loop typically involves these steps:
Setting the model to training mode using model.train() [22, 23]. This tells the model to track gradients so that they can be used to update the model’s parameters [23].
Performing a forward pass by passing the data through the model.
Calculating the loss by comparing the model’s prediction with the actual data labels.
Setting gradients to zero using optimizer.zero_grad() [24].
Performing backpropagation using loss.backward() [15, 24].
Updating the model’s parameters using optimizer.step() [24].
During training, models can have two modes: train and evaluation.
The train mode tracks gradients and other settings to learn from the data [22, 23].
The evaluation mode turns off settings not needed for evaluation such as dropout, and it turns off gradient tracking to make the code run faster [25, 26].
Other key points about the model training process are:
Hyperparameters: The training process involves the use of hyperparameters, which are values set by the user, like the learning rate or the number of epochs [5, 23].
Experimentation: Model training is often an experimental process, with various parameters and settings being tried to find the best performing model [27, 28].
Data: The quality and quantity of the training data has a big effect on the model’s performance [29, 30].
Reproducibility: Randomness is an important part of training; to reproduce results, it is necessary to set random seeds [31, 32].
Visualization: Visualizing model training through metrics such as accuracy and loss curves is important in understanding whether the model is learning effectively [33-35].
Inference: When making predictions after training, the term inference is also used [36]. Inference uses a model to make predictions using unseen data [26, 36].
In summary, the model training process in machine learning involves iteratively adjusting a model’s parameters to minimize error by using the techniques of gradient descent and backpropagation [1, 2, 14, 15].
PyTorch Model Deployment
The sources discuss model deployment in the context of saving and loading models, which is a key part of making a model usable in an application or other context. Here’s a breakdown of model deployment methods based on the sources:
Saving Models:State Dictionary: The recommended way to save a PyTorch model is to save its state dictionary [1, 2]. The state dictionary contains the model’s learned parameters, such as weights and biases [3, 4]. This is more flexible than saving the entire model [2].
File Extension: PyTorch models are commonly saved with a .pth or .pt file extension [5].
Saving Process: The saving process involves creating a directory path, defining a model name, and then using torch.save() to save the state dictionary to the specified file path [6, 7].
Flexibility: Saving the state dictionary provides flexibility in how the model is loaded and used [8].
Loading Models:Loading State Dictionary: To load a saved model, you must create a new instance of the model class and then load the saved state dictionary into that instance [4]. This is done using the load_state_dict() method, along with torch.load(), which reads the file containing the saved state dictionary [9, 10].
New Instance: When loading a model, it’s important to remember that you must create a new instance of the model class, and then load the saved parameters into that instance using the load_state_dict method [4, 9, 11].
Loading Process: The loading process involves creating a new instance of the model and then calling load_state_dict on the model with the file path to the saved model [12].
Inference Mode:Evaluation Mode: Before loading a model for use, the model is typically set to evaluation mode by calling model.eval() [13, 14]. This turns off settings not needed for evaluation, such as dropout layers [15-17].
Gradient Tracking: It is also common to use inference mode via the context manager torch.inference_mode to turn off gradient tracking, which speeds up the process of making predictions [18-21]. This is used when you are not training the model, but rather using it to make predictions [19].
Deployment Context:Reusability: The sources mention that a saved model can be reused in the same notebook or sent to a friend to try out, or used in a week’s time [22].
Cloud Deployment: Models can be deployed in applications or in the cloud [23].
Model Transfer:Transfer Learning: The source mentions that parameters from one model could be used in another model; this process is called transfer learning [24].
Other Considerations:Device Agnostic Code: It is recommended to write code that is device agnostic, so it can run on either a CPU or a GPU [25-27].
Reproducibility: Random seeds should be set for reproducibility [28, 29].
Model Equivalence: After loading a model, it is important to test that the loaded model is equivalent to the original model by comparing predictions [14, 30-32].
In summary, model deployment involves saving the trained model’s parameters using its state dictionary, loading these parameters into a new model instance, and using the model in evaluation mode with inference turned on, to make predictions. The sources emphasize the importance of saving models for later use, sharing them, and deploying them in applications or cloud environments.

The speaker repeatedly stresses the need for unity (ittehad), solidarity (yakjehti), and making differences a source of “mercy” rather than conflict.
He criticizes those who use petty differences to declare other Muslims as infidels (takfir), emphasizing the need to overcome sectarian divisions and approach disagreements with moderation.
Quote:“It’s time to create unity, unity and solidarity, make differences a mercy, don’t make them a burden. They used to convert the disbelievers into Muslims on the basis of petty differences and personal natures. Some schools of thought make Muslims infidels because of hatred.”
He argues that all Islamic schools of thought contain some part of the truth, and that no single school holds a monopoly on it.
Quote:“It is not that all truth is limited to only one school of thought. The truth is contained in all Islamic schools of thought and religions. Everyone has some part of the right…”
The speaker advocates for a focus on shared heritage of Hadith and Sunnah, specifically emphasizing the love of the Prophet Muhammad ( Ishq wa Mohabbate Rasool) as the basis for unity.
Quote:“If we were gathered on the basis of Hadith and Sunnah, as if we gathered on the basis of Ishq wa Mohabbate Rasool.”
The Importance of Hadith and Sunnah:
The speech places great importance on Hadith and Sunnah, the practices of the Prophet, as central to Islamic life.
He frames Sahih al-Bukhari as a critical resource for the understanding of these traditions, emphasizing the immense value of this particular collection. He describes it as a “boat” that saves one from sinking even if a storm comes.
He highlights the recitation of Sahih al-Bukhari as having spiritual and healing benefits.
Quote:“Recitation of Sahih Bukhari averts diseases so great…”
The speaker also criticizes the idea that all authentic hadith are found solely in Sahih al-Bukhari, asserting that many other authentic hadith exist. This point is emphasized multiple times with supporting quotes from classical scholars. He stresses, “Confining Sahih Hadith to Sahih Bukhari is not a form of knowledge. Ignorance is the sign of ignorance.”
Reverence for Imam Bukhari:
The speaker expresses deep reverence for Imam Bukhari, highlighting his piety, scholarship, and love for the Prophet.
He shares anecdotes from Bukhari’s life, including a story of his mother’s prayers restoring his eyesight, his exceptional memory for hadith, and his intense devotion to the Quran.
Quote:“Imam Muhammad Bin Ismail Bukhari was still a child when his eyes started to see. Now Imam Bukhari is starting the Tazkira from here Your mother, Majda, was a very devout Abida. She cried a lot and prayed in her dreams Ibrahim (peace be upon him) was visited. Now this is the incident that I am describing.”
He details the numerous classical scholars who praised and admired Bukhari’s contributions to the field of hadith.
He mentions Bukhari’s refusal to teach in royal courts and his subsequent expulsion, drawing a parallel to contemporary issues of scholars succumbing to political pressures and selling their religious knowledge for personal gain.
The History and Significance of Khatam al-Bukhari:
The speaker explores the history of holding gatherings to commemorate the completion (khatam) of Sahih al-Bukhari, attributing the practice to Imam Ibn Hajar al-Asqalani, whom he describes as the ‘Ameerul Momineen’ of hadith. He also mentions his own participation in one such event when he was nine years old.
He describes the grand scale of such gatherings and the importance they hold in the tradition of hadith study.
Critique of Extremism and Takfir:
The speech strongly denounces extremism, particularly the practice of declaring fellow Muslims as kafir (unbeliever).
Quote:“Let’s tear down the walls Takfir change and tear down the walls of confusion. The ancestors used to bring non-Muslims into the circle of Islam with the blessing of their words and deeds. We were Muslims by working hard all our lives. Excluded from the circle of Islam.”
He connects takfir with small personal differences and differences in nature, claiming that such practices are against the spirit of Islam.
He criticizes the Khawarij, an early sect known for their extremism, for their flawed understanding of Tawheed (monotheism), warning his audience not to follow their interpretation. He draws on the writings of Allama Ibn Taymiyyah to support this view.
Love for the Prophet Muhammad:
The speaker emphasizes the importance of love for the Prophet Muhammad (Ishq-e-Rasool) as a core element of faith. He believes that love should be accompanied by a genuine effort to adhere to the Prophet’s teachings.
He highlights various passages from Sahih al-Bukhari that showcase the Prophet’s virtues and the deep love and devotion he inspired in his companions. He draws attention to Imam Bukhari’s placement of the book on the beginning of revelation as the first book of Sahih al-Bukhari to demonstrate the importance of Prophethood.

FAQ: Unity, Knowledge, and the Legacy of Imam Bukhari
What is the primary call of this discourse, and what issues does it seek to address?
The primary call is for the unity and solidarity of the Muslim Ummah, emphasizing that differences should be a source of mercy, not division. The speaker argues against takfir (declaring fellow Muslims as infidels) based on minor differences in schools of thought or personal inclinations, which they see as a corruption of true Islamic teachings. The discourse aims to dismantle the walls of confusion, extremism, and hatred that have led to divisions within the Muslim community.
How does the speaker view the various schools of thought within Islam, and what does this have to do with the overall theme?
The speaker believes that all Islamic schools of thought contain some part of the truth and that no single school possesses the entirety of it. He argues against the notion that one school is entirely correct while all others are wrong, promoting instead a view that differences should be viewed as a mercy. This perspective is fundamental to the theme of unity, as it challenges the exclusivity that fuels division. The speaker emphasizes that focusing on the common ground, especially the love of the Messenger and the Hadith and Sunnah, is more important than using differences to create conflict. He himself identifies as Hanafi in fiqh, Ash’ari in belief, and Qadri in Tariqa.
What is the significance of Sahih al-Bukhari in this discourse?
Sahih al-Bukhari is presented as a central unifying factor for the Ummah. It is not just a book of hadith, but a source of knowledge, guidance, and spiritual connection to the Prophet Muhammad (peace be upon him). The speaker stresses the immense value of this collection, emphasizing its accuracy and reliability, highlighting the discovery of a 750-year-old manuscript that confirms the authenticity of its text. Reciting and studying Sahih al-Bukhari is seen as a way to avert diseases, receive blessings and connect the faithful to the Prophet Muhammad (peace be upon him). The speaker advocates for gathering on the basis of Hadith and Sunnah, embodied in Sahih al-Bukhari.
What historical context is given regarding the tradition of concluding Sahih al-Bukhari with a large gathering?
The tradition of holding large gatherings at the completion (Khatm) of Sahih al-Bukhari is attributed to Imam Ibn Hajar al-Asqalani, who organized a grand feast after completing his commentary on Sahih al-Bukhari, Fath al-Bari, in 842 AH. This event is used as an example of how the end of a book is not the end of its effects but an occasion for learning and unity, demonstrating that such gatherings are a tradition of knowledge, blessing, and beauty across schools of thought.
What is the speaker’s view on the relationship between knowledge, piety, and actions, particularly as it pertains to Imam Bukhari?
The speaker emphasizes that true knowledge is inseparable from piety, righteousness, and good actions. Imam Bukhari’s life is presented as the ideal integration of these elements, with his immense knowledge being complemented by his devotion to worship and asceticism. The speaker highlights Imam Bukhari’s extensive Quran recitations during Ramadan, emphasizing that the blessings of knowledge are greater when they are accompanied by the same level of righteous acts of worship. He also suggests a key to understanding Sahih al-Bukhari is that it begins with the mention of prophethood, and ends with the mention of Tawheed, noting that faith will remain imperfect without Tawheed and proper actions.
How does the speaker discuss the importance of understanding Imam Bukhari’s personality and life to better understand his work?
The speaker explains Imam Bukhari faced jealousy and hardship, and rejected the request of the ruler of Bukhara to teach Sahih al-Bukhari in his palace, saying “I do not humiliate knowledge, nor do I raise knowledge at the gates of kings”. This was not only a display of bravery, but is also presented as a great piece of advice for students of religion. The speaker notes that his actions led to him being expelled from Bukhara which highlights Imam Bukhari’s immense love for knowledge as well as his devotion and loyalty to Allah over material pursuits. The speaker highlights his struggles and ultimate glory after death to show that Imam Bukhari had a high status in life and in death, exemplifying the importance of preserving knowledge. This is also meant to underscore that the speaker values knowledge and religion over worldly gain.
What does the speaker say about the unique structure and content of Sahih al-Bukhari in relation to its author’s love for the Prophet Muhammad (peace be upon him)?
The speaker emphasizes that Sahih al-Bukhari is unique in its structure. Instead of beginning with the Book of Faith or purification, it starts with Bada al-Wahhi, the book about the beginning of revelation and Prophethood. This demonstrates that Imam Bukhari was a lover of the Messenger and that his book begins with a mention of Prophethood and ends with a discussion of tawheed which illustrates the core of his work and faith as being rooted in the message of Prophethood. He also discusses how Imam Bukhari repeated certain hadith related to the love and reverence for the Messenger multiple times in the text, and even highlights how Imam Bukhari ended Sahih al-Bukhari with the hadith relating to the praise and glorification of Allah.
What is the significance of the speaker presenting his sanad (chain of transmission) at the conclusion of this lesson?
The speaker presents his sanad as a demonstration of the connection he has with the great scholars of the past all the way up to the Prophet Muhammad (peace be upon him). He emphasizes the small number of intermediaries between himself and key figures of the past such as Shah Waliullah Muhaddith Dehlavi, Imam Ibn Hajar al-Asqalani, and Imam Jalaluddin Suyuti, as well as his direct connection with several living scholars who had direct connections to the most famous scholars in history. This highlights the value and importance of a living tradition in which knowledge is passed down, and how that same knowledge connects him to both the historical Islamic tradition as well as the Prophet Muhammad (peace be upon him). He also uses his sanad as the means to grant permission to all the listeners of the lesson to participate in this tradition of knowledge, and to show that the tradition is still alive and vibrant to this day.

Islamic Unity: A Call for Solidarity
The sources emphasize the importance of unity and solidarity within the Muslim Ummah, highlighting the need to overcome sectarianism and conflict [1, 2]. Several key points about Islamic unity are discussed:
Common Ground: The sources stress focusing on the commonalities of Islam, such as the Quran, Hadith, and Sunnah, rather than differences in schools of thought [2]. It is noted that all Islamic schools of thought contain some part of the truth [3]. The common love and respect for the Prophet Muhammad is also emphasized as a basis for unity [1, 3].
Rejection of Extremism: There is a call to eliminate extremism and sectarianism, with the need for moderation and centrality emphasized [2, 3]. The sources argue that differences should be seen as a mercy, not a burden, and that Muslims should not declare each other infidels over minor disagreements [1, 4, 5].
Importance of Hadith and Sunnah: The sources argue that the protection and revival of religion requires focusing on the knowledge of Hadith and Sunnah. It is stated that unity is not possible without this protection [1, 2, 5]. Connecting with the righteous Salaf (early generations of Muslims) through Hadith and Sunnah is presented as a way to revive the culture of knowledge [2].
The Role of Scholars: Scholars are urged to promote unity and solidarity rather than division [1, 2, 4]. It is mentioned that scholars should not sell their consciences or character for worldly gain [6]. The sources emphasize that scholars and students should keep in mind that the knowledge of hadith is not limited to Sahih Bukhari alone, but is contained in other books as well [7, 8].
Historical Context: The sources refer to historical figures, such as Imam Ibn Hajar al-Asqalani, who organized gatherings to celebrate the completion of hadith books to emphasize the importance of knowledge and unity [9, 10]. The sources present a historical perspective on how the pursuit of knowledge and unity was a shared goal among various Islamic schools of thought. The narrators of Sahih Bukhari include both Muhaddith and Sufi mystics, showing the combination of these aspects [11-13].
Practical Steps: The sources call for tearing down the “walls of confusion” and “walls of Takfir,” referring to the practice of declaring other Muslims infidels [5, 6, 14]. The idea is to revive the values of religion by emphasizing the love of the Prophet and the knowledge of Hadith [4, 10, 15]. The sources also suggest focusing on commonalities and seeking the truth in all Islamic schools of thought [2-4].
Call to Action: The sources conclude with an announcement to tear down the walls of hatred and unite the Ummah based on the teachings of the Prophet, the Quran, and the Sunnah, while following the example of Imam Bukhari and the predecessors [1, 2, 14, 16].
Overall, the sources present a view of Islamic unity based on shared principles, mutual respect, and a commitment to knowledge and the teachings of the Prophet. The emphasis is on moving beyond sectarianism and focusing on the common goals of the Muslim Ummah.
Hadith, Sunnah, and Islamic Unity
The sources discuss the importance of Hadith knowledge, its preservation, and its role in Islamic unity and practice. Here are some key points:
Central Role of Hadith and Sunnah: The sources emphasize that Hadith and Sunnah are essential for the protection and revival of religion [1, 2]. It’s stated that unity among Muslims is not possible without focusing on Hadith and Sunnah [1, 2]. The sources suggest that a connection to the righteous Salaf (early generations of Muslims) through Hadith and Sunnah is vital to revive the culture of knowledge [2].
Sahih Bukhari: The text discusses Sahih Bukhari extensively, noting its significance as a primary source of Hadith [1-28]. It highlights the meticulousness of Imam Bukhari in compiling the book, who is said to have memorized 100,000 authentic and 200,000 non-authentic hadiths [29].
Not Limited to One Book: The sources make it clear that Hadith knowledge is not limited to Sahih Bukhari alone [5, 30]. It is noted that Imam Bukhari himself stated that he left out many authentic hadiths to keep the book from becoming too long [5, 30]. It is also mentioned that Imam Muslim did the same, and that other books also contain authentic hadith [30, 31]. To only accept hadith from Sahih Bukhari is considered a sign of ignorance [5].
Importance of the Chain of Narration: The sources discuss the importance of the chain of narrators (Isnad) in verifying the authenticity of Hadith [5, 25-28, 32-36]. The transmission of Hadith through various scholars is highlighted with emphasis on the reliability of the narrators [4, 6, 8, 9, 27, 28, 33, 35, 37].
Love for the Prophet: The text illustrates how Imam Bukhari’s compilation of Hadith was motivated by his deep love and respect for the Prophet Muhammad [1, 11-13, 17, 18, 22-24, 38, 39]. Imam Bukhari is said to have started his book with the mention of Prophethood and ended with the knowledge of Tawheed [40, 41]. The sources contain various hadiths about the Prophet’s life, actions, and character, emphasizing his importance in the Muslim faith [4, 12, 17, 20-22, 40].
Practical Application: The text discusses the concept of tawassul, which is using the recitation of Sahih Bukhari as a means to seek blessings, cure diseases, and ask for help from Allah [1, 6]. The sources emphasize that the true claim of love for the Prophet (Ishq Rasool) is shown through adapting to the actions and character of the Prophet Muhammad, including following his ways in eating, drinking, praying, and other aspects of life [22, 23].
Levels of Authenticity: The sources describe a seven-level system for categorizing the authenticity of hadith, with Sahih Bukhari and Sahih Muslim at the top, followed by hadith recorded by either one of them, and then by other scholars who met specific conditions [31]. This highlights the meticulousness and systematic approach to hadith verification within Islamic scholarship [32].
Sufism and Hadith: The sources note that both Muhaddith scholars of hadith and Sufi mystics were among the narrators of Sahih Bukhari [9, 10, 33, 42]. This connection between Hadith and Sufism indicates that these two traditions were not separate and that knowledge and spirituality were both important in the preservation and transmission of Hadith [43].
Rejection of Extremism: The sources state that Imam Bukhari rejected the ideas of the Khawarij, an early Islamic sect, at the end of Kitab al-Tawheed, as a warning against extremism [14, 15, 44]. The Khawarij are considered the founders of innovation in the history of Islam, and the source emphasizes that Muslims should not take their interpretation of Tawheed or their ideas about who is a believer and who is not [15, 44].
Importance of Scholars: Scholars are portrayed as having a vital role in preserving, transmitting, and explaining the Hadith [5, 11, 14, 23, 30, 40, 43-46]. They are urged to promote unity and solidarity, and to avoid selling their principles for personal gain [23, 46].
In summary, the sources highlight that Hadith knowledge is central to understanding and practicing Islam and that it promotes unity and love for the Prophet, while also warning against extremism and division. The sources emphasize that a true understanding of hadith comes from careful study, adherence to the chain of narration, and putting the teachings into practice.
Sahih Bukhari: A Comprehensive Overview
The sources discuss Sahih Bukhari as a central text in Islam, revered for its collection of hadith, and emphasize its importance in various aspects of Islamic faith and practice [1-4]. Here’s a detailed overview:
Compilation and Significance: Sahih Bukhari is described as one of the most reliable versions of Sahih Bukhari and is a highly respected collection of hadith [3]. It was compiled by Imam Muhammad bin Ismail al-Bukhari, who is portrayed as a great scholar, with a deep love for the Prophet Muhammad [4, 5]. Imam Bukhari is said to have memorized 100,000 authentic hadith and 200,000 non-authentic hadith [6, 7]. He selected hadith for the book from a collection of six lakh hadith [6].
Structure and Content:
The first book of Sahih Bukhari, Bada al-Wahi, begins with the mention of Prophethood and how the revelation was revealed to the Prophet Muhammad [4, 8]. This is unique, as other collections of hadith begin with other subjects, such as the Book of Faith [9].
The second book of Sahih Bukhari is Kitab al-Iman, or the Book of Faith. In this book, Imam Bukhari includes Bismillah, “In the name of Allah, the Most Gracious, the Most Merciful,” at the beginning of the second chapter, but did not do so in the first book, which is about the Prophet [10].
The last book of Sahih Bukhari is Kitab al-Tawheed, which deals with the concept of the oneness of God [11].
The book concludes with a condemnation of the Khawarij, an early Islamic sect considered heretical [12, 13].
The last hadith in the collection is on the glorification of God [11, 12].
The sources note that the hadith in Sahih Bukhari relate to the words and actions of the Prophet Muhammad but that the collection also includes the regulations, follow-ups, and comments of the scholars. The number of the hadith in the collection is approximately 7563, or 9082 if all the regulations, comments, and observations are counted. The number of hadith where only the words of the Prophet are recorded is 2607, with an additional 1341 pending [14].
The collection includes 97 books and 386 chapters [15]. The narrators in the collection number 1597, with 42 female narrators. There are 153 Companions of the Prophet who are mentioned, and 304 sheikhs who are direct teachers of Imam Bukhari [15].
Preservation and Transmission: The sources emphasize that the preservation of Hadith is a divine blessing. A specific manuscript of Sahih Bukhari written 750 years ago is highlighted to show the accuracy of transmission [3]. The manuscript, written by Imam Sharafuddin Union, was hidden and then rediscovered centuries later [3]. There are various manuscripts of Sahih Bukhari all over the world with little differences, which highlights its accurate preservation over time [3].
Commentaries and Gatherings:
The sources mention that scholars organize gatherings to celebrate the end of the reading of Sahih Bukhari, with the first such event held by Imam Ibn Hajar al-Asqalani [4, 16]. Such gatherings, and the recitation of the entire book, is referred to as Khatam al-Bukhari [17].
Commentaries on Sahih Bukhari, such as Fath al-Bari, by Imam Ibn Hajar al-Asqalani, are also discussed, highlighting the tradition of scholarly analysis of this text [16].
The sources note the historical practice of celebrating the completion of Sahih al-Bukhari, which involves large gatherings of scholars and other prominent people [16, 18].
Such gatherings are described as a way to revive the culture of knowledge [18].
Role in Islamic Life:
The recitation of Sahih Bukhari is believed to avert diseases, and to bring blessings and solutions to problems [19, 20]. The concept of tawassul, using Sahih Bukhari as a means to seek blessings from Allah is mentioned [1].
The text states that traveling with Sahih Bukhari can save a boat from sinking, highlighting the symbolic and spiritual value attached to the book [1, 19].
The sources state that Imam Bukhari included many hadith about the love of the Prophet and the importance of following the Prophet’s example [21, 22].
Authenticity and Scope:
The sources note that not all authentic hadith are contained within Sahih Bukhari [7, 23, 24]. Imam Bukhari himself is quoted as saying that he did not include all authentic hadith in his collection to keep it from being too large [7, 23]. It is emphasized that other books of hadith also contain authentic material, and that it is ignorance to limit authentic hadith to the contents of Sahih Bukhari alone [7, 23].
The sources discuss a seven-level system for categorizing the authenticity of hadith, which is based on which collections the hadith is found in, and whether the hadith meets the specific conditions of hadith scholars. According to this system, hadith in Sahih Bukhari and Sahih Muslim are the most authentic, but hadith in other collections may also be considered authentic [24].
Imam Bukhari’s Character and Methods:
Imam Bukhari is described as a very pious man, who was known for his devotion to prayer and reading the Quran [25]. It is mentioned that his mother prayed for him and that he was granted the blessing of having his eyesight restored.
The text highlights Imam Bukhari’s refusal to bring knowledge to the courts of kings, and his decision to be exiled instead, which is used as an example of how scholars should not compromise their principles for worldly gain [26, 27].
The text emphasizes Imam Bukhari’s love for the Prophet, as evidenced by the way he structured his book, by his selection of hadith, and by his personal devotion to the Prophet [8, 9].
Imam Bukhari is said to have visited the grave of the Prophet before writing his collection [19].
Narrators of Sahih Bukhari: The sources name various scholars who transmitted Sahih Bukhari and include both Muhaddith (scholars of hadith) and Sufi mystics [28]. The four most famous are Imam Ibrahim bin Muhaq Al-Nusr Ash’arabat al-Bukhari, Imam Abu Muhammad Hamad bin Shakir al-Nasfi, Imam Abu Talha Mansoor bin Muhammad al-Bazi, and Imam Abu Abdullah Muhammad bin Yusuf al-Farbari [15, 28]. Imam Farbari is considered the most reliable source for the text of Sahih Bukhari, and the lineage of the transmission of hadith to Imam Farbari is detailed [28].
Relevance to Contemporary Issues: The sources connect the importance of Sahih Bukhari to the contemporary issue of sectarianism, stating that Muslims should unite on the basis of shared beliefs and practices, as taught in the hadith. They also emphasize the need to avoid declaring other Muslims infidels [1, 2]. The text argues that the Khawarij, who are condemned at the end of Sahih Bukhari, are an example of the dangers of extremism and declaring other Muslims as infidels [12, 13].
In summary, Sahih Bukhari is portrayed as a highly important and reliable collection of hadith, compiled by a great scholar who was deeply devoted to the Prophet Muhammad. The text emphasizes the book’s importance in Islamic life, while also cautioning against limiting Hadith knowledge to this book alone and using it to justify division and extremism [8, 9].
Love for the Prophet Muhammad in Islam
The sources emphasize the profound significance of love for the Prophet Muhammad (Ishq Rasool and Mohabbate Rasool) in Islam, portraying it as a core element of faith and practice, and a central theme in Sahih Bukhari [1, 2]. Here’s a detailed exploration of this concept:
Centrality of Love for the Prophet: The sources assert that love for the Prophet is a fundamental aspect of Islamic belief and practice [2, 3]. It is presented not just as an emotion but as a defining principle that should shape the actions and character of a believer [4, 5]. This love is not just a matter of personal devotion but also a foundation for unity among Muslims [3].
Manifestations of Love: The sources describe several ways in which love for the Prophet is expressed:
Following the Prophet’s example: True love for the Prophet is demonstrated by adhering to his teachings and emulating his behavior and character [4, 5]. This includes adopting his ways in matters of eating, drinking, praying, and all other aspects of life [5].
Deep respect and longing: The sources highlight a deep respect and yearning for the Prophet. Imam Bukhari is described as having a deep love for the Prophet, and this love motivated him to collect hadith [6, 7].
Recitation of Sahih Bukhari: The text notes that the recitation of Sahih Bukhari, which contains the Prophet’s words and actions, is a form of expressing love and seeking blessings [8, 9].
Gatherings and celebrations: Organizing gatherings to celebrate the end of the reading of Sahih Bukhari is seen as an expression of love for the Prophet and a way to revive the culture of knowledge [10].
Love for the Prophet in Sahih Bukhari: The sources highlight Imam Bukhari’s emphasis on the Prophet’s love in his collection of hadith:
Starting with Prophethood: Imam Bukhari begins his book with the mention of Prophethood, which is unique among other hadith collections [2]. This is presented as an indication of the Imam’s focus on the Prophet and his message [11].
Hadith Selection: Imam Bukhari is said to have selected hadiths that show the love of the Prophet in various contexts [2]. He emphasizes the love of the Prophet in twelve places, while also including 33 hadith about the Prophet and his family, particularly Sayyida Fatima, Sayyidna Ali, Sayyidna Imam Hasan, and Sayyidna Imam Hussain [12].
Recurring Themes: The sources highlight recurring themes in Sahih Bukhari that demonstrate love and respect for the Prophet. For instance, the incident of the Prophet showing his face during prayer is repeated six times, and the incident of Sayyiduna Siddique Akbar stepping aside during prayer to allow the Prophet to lead the prayer is repeated nine times in the collection [12-15]. These are seen as examples of the Imam’s emphasis on the Prophet’s importance and the love and devotion he inspired [16, 17].
Emphasis on the Prophet’s character: The first few hadith in Sahih Bukhari highlight the Prophet’s character, including his good behavior after the first revelation, and Sayyidah Khadijah’s description of his virtues [11].
The Trunk of the Date Palm: The sources describe how Imam Bukhari includes hadith relating how the dry trunk of a date palm cried when the Prophet began using a different place to deliver his sermons. This illustrates the love and connection between the Prophet and even inanimate objects [17, 18].
Love as a Condition of Faith: The sources stress that love for the Prophet is so important that it is essential for the perfection of faith. The hadith states that a person’s faith is not complete until they love the Prophet more than they love their own lives, parents, and children [12, 19].
Love and Deeds: The sources make it clear that love for the Prophet must be accompanied by righteous deeds [4, 5]. It should not be a mere claim or empty custom [4]. True love, according to the sources, manifests in adopting the Prophet’s character and following his teachings [5].
Avoiding Extremism: The text emphasizes that love for the Prophet must be balanced with a proper understanding of Islamic teachings. It warns against extremism and declaring other Muslims infidels. The sources condemn the Khawarij, who are presented as an example of those who are considered heretics because they did not adhere to the Sunnah and the example of the Prophet and the companions [20, 21].
Love as a Means to Divine Favor: The sources connect love for the Prophet with seeking divine favor and blessings from God. They highlight that those who love the Prophet and follow his example are more likely to receive Allah’s grace [4, 5].
Unity Through Love: The sources portray love for the Prophet as a unifying factor for the Muslim community, and they emphasize the need to focus on the common love for the Prophet and his teachings as a means of overcoming division and sectarianism [1, 22].
In summary, the sources depict love for the Prophet Muhammad as an indispensable aspect of the Islamic faith, which is to be demonstrated through devotion, emulation of his character, and righteous deeds. This love is presented as a unifying force for the Muslim community, a means to seek divine favor, and a central theme in the teachings of Sahih Bukhari.
Islamic Schools of Thought: Unity in Diversity
The sources discuss religious schools of thought within Islam, emphasizing both their diversity and the need for unity despite differences. Here’s a breakdown of the key points:
Diversity of Schools: The sources acknowledge the existence of various Islamic schools of thought (Masalik) [1], including:
Schools of jurisprudence: Hanafi, Maliki, Shafi’i, and Hanbali schools of jurisprudence are specifically mentioned [2]. The speaker identifies as following the Hanafi school of jurisprudence [3].
Schools of belief: The speaker identifies as being from the Ahle Sunnat Wal Jamaat in terms of belief [3].
Sufi orders: The Qadri order (Tariqat) is mentioned [3].
Other groups: The text also refers to the Deoband and Bareilly schools of thought [4].
The text also refers to the Ahl al-Hadith or Salafi school of thought [5, 6].
Commonalities: Despite the differences between these schools, the sources stress that there are more commonalities than differences [7].
The core of the religion, the Hadith and Sunnah of the Prophet, is a common ground for all [1, 7]. The sources emphasize the need to focus on these commonalities rather than the differences to foster unity and solidarity [7].
Love for the Prophet is presented as the greatest common asset of the Ummah, and a basis for unity [3].
Validity of Different Schools: The sources suggest that all Islamic schools of thought contain some part of the truth [3, 8]. It is asserted that no single school possesses the entirety of the truth, but rather, each has a portion of it [3].
The speaker argues against the idea that only one school of thought is correct, stating that “the right lies in all of them” [3].
The speaker uses the analogy of heaven to demonstrate this point, stating it would be illogical for only one Imam to be admitted to heaven while others are excluded [8]. The speaker wonders where the Imams such as Sufyan Thori, Abdullah Bin Mubarak, Sufyan Ibn Aina, Waqi bin Al-Jarrah, Imam Bukhari and Imam Muslim will be placed if that were the case [8].
The text states that the truth is contained in all Islamic schools of thought and religions, and everyone has some part of the right [3].
Sectarianism and Conflict: The sources strongly condemn sectarianism and sub-religious conflicts, emphasizing the need to eliminate or minimize such divisions [7]. The sources express concern that differences have led to Muslims declaring each other infidels [1, 9]. The sources highlight that in the past, people used to bring non-Muslims into Islam through their good behavior, whereas now Muslims exclude each other from Islam because of minor differences [9].
Unity and Solidarity: The text emphasizes the importance of unity and solidarity (Ittihad wa Ittifaq) within the Ummah [1, 7]. The speaker calls for the demolition of the “walls” of division and confusion [1, 9] and for focusing on what unites Muslims, such as the love of the Prophet and the knowledge of the Hadith and Sunnah [1, 3, 7]. The sources call for unity based on the knowledge of Hadith and Sunnah [7].
Moderation and Centrality: The sources stress the need to create moderation and centrality within the Ummah and to eliminate extremism [3]. It is noted that there is a need to revive the culture of knowledge and connection with Hadith and Sunnah, which have been disconnected [5, 7].
The Importance of Knowledge: The sources see a connection between religious knowledge and unity. By focusing on commonalities through the Hadith and Sunnah, Muslims can avoid the problems of sectarianism and conflict.
In summary, the sources advocate for a balanced approach that acknowledges the diversity of Islamic schools of thought while emphasizing the need for unity, mutual respect, and a focus on the common ground of the Hadith, Sunnah, and love for the Prophet. The sources call for setting aside differences and sectarianism for the sake of unity within the Ummah and the pursuit of common religious goals.

“Basic Writings of Bertrand Russell” showcases Russell’s prolific engagement with philosophical issues. He tackles topics like the nature of knowledge, the validity of logic, the role of science in human life, and the complexities of ethics and religion. Numerous passages from his different works demonstrate his evolving views on these topics.
Russell expresses his profound skepticism towards traditional religious dogmas and metaphysical assumptions. He emphasizes the importance of empirical evidence and logic in understanding the world, arguing that a scientific approach is crucial to solving social and political problems.
Russell also critiques the pursuit of power and the dangers of nationalism, advocating for international cooperation and a more compassionate approach to human affairs. He aims to liberate the human mind from superstition and dogma, encouraging a spirit of inquiry and critical thinking.
1-An Overview of Bertrand Russell’s Life and Works
Bertrand Russell was a prolific writer, philosopher, and social critic who lived from 1872 to 1970.
His wide-ranging interests included mathematics, philosophy, economics, history, education, religion, politics, and international affairs.
While he considered his technical work in logic and philosophy to be his most significant contribution, he also wrote extensively on various other topics, aiming to engage a broader audience and contribute to improving the state of the world.
He believed in the importance of clear and precise thinking and was critical of those who relied on dogma or obscured their arguments with vague language.
1.1 Early Life and Influences
Orphaned at a young age, Russell was raised by his grandparents in a home steeped in the tradition of aristocratic liberalism.
His grandmother instilled in him a love of history and a strong sense of individual conscience.
At age eleven, he developed a passion for mathematics, seeking certainty and the ability to “prove things.”
However, his hopes were dashed when his brother informed him that Euclidian axioms could not be proven.
His intellectual development was further shaped by writers like John Stuart Mill, whose works on political economy, liberty, and women’s rights deeply influenced him.
1.2 Intellectual Journey and Shifting Interests
Russell’s early work focused on mathematics, philosophy, and economics.
He initially found profound satisfaction in mathematical logic, feeling an emotional resonance with the Pythagorean view of mathematics as having a mystical element.
Over time, his philosophical interests shifted towards a theory of knowledge, psychology, and linguistics, as he sought to understand the nature of knowledge and its relationship to perception, language, and belief.
This shift marked a “gradual retreat from Pythagoras” and a growing emphasis on empirical evidence and logical analysis.
He maintained that philosophy should focus on clarifying complex concepts and seeking truth through rigorous inquiry, rather than constructing grand metaphysical systems.
1.3 Key Philosophical Contributions
One of Russell’s most notable contributions to philosophy is his theory of descriptions, which distinguishes between knowledge by acquaintance and knowledge by description.
He argued that we are only directly acquainted with our sense data and that knowledge of everything else is derived through descriptions.
He also made significant advances in the field of logic, developing symbolic logic and challenging traditional Aristotelian logic.
He believed that symbolic logic was essential for understanding mathematics and philosophy and that traditional logic was outdated and inadequate.
Russell was a strong advocate for empiricism, emphasizing the importance of observation and experience in acquiring knowledge.
He believed that scientific methods should be applied to philosophical inquiry and that claims should be based on evidence rather than speculation.
1.4 Views on Religion and Ethics
A lifelong agnostic, Russell was critical of organized religion and its reliance on dogma.
He famously argued in his essay “Why I Am Not a Christian” that there was no evidence to support the existence of God and that religious beliefs were often harmful and used to justify oppression.
His views on ethics, particularly on sexual morality, were often controversial, as he challenged traditional norms and advocated for greater personal freedom.
He believed that morality should be based on human happiness and well-being rather than on religious precepts or social conventions.
1.5 Political and Social Activism
Throughout his life, Russell was actively engaged in political and social issues, advocating for peace, democracy, and individual liberty.
He was a vocal critic of war and nationalism, arguing that these forces were detrimental to human progress.
He was also a staunch critic of both communism and fascism, believing that they led to tyranny and oppression.
He was particularly concerned with the dangers of unchecked power, both political and economic, and argued for the importance of individual rights and freedoms.
1.6 Legacy and Impact
Bertrand Russell’s contributions to philosophy, logic, and social thought have had a lasting impact on intellectual discourse.
He is considered one of the most important figures in 20th-century philosophy and his works continue to be widely read and studied.
His clear and engaging writing style, combined with his willingness to tackle controversial topics, made him a popular public intellectual and helped to bring philosophical ideas to a wider audience.
While his views were often met with criticism and controversy, his commitment to rational inquiry, individual freedom, and human well-being left an undeniable mark on the intellectual landscape.
2-Exploring Russell’s Perspective on the Philosophy of Logic
Bertrand Russell’s writings offer insights into his perspective on logic and its philosophical underpinnings. Russell viewed symbolic logic as crucial for philosophical inquiry, seeing it as a tool for analyzing language, dissecting arguments, and revealing the structure of thought.
2.1 Symbolic Logic and its Significance
Russell championed symbolic logic as a more rigorous and powerful system than traditional Aristotelian logic, arguing that it was essential for both philosophy and mathematics. He saw symbolic logic as the study of general types of deduction, capable of handling more complex inferences than the traditional syllogism. This view challenged the long-held dominance of Aristotelian logic and significantly influenced the development of modern logic and analytic philosophy.
2.2 Logic as the Foundation of Mathematics
Russell argued that mathematics is essentially a continuation of logic, demonstrably built upon the same fundamental principles. This view, a radical departure from prevailing thought, debunked Kant’s theory that mathematical propositions were synthetic and reliant on our understanding of time. The groundbreaking work Principia Mathematica, co-authored by Russell and Alfred North Whitehead, meticulously demonstrated the derivation of mathematics from logical axioms.
2.3 Language and Its Role in Logic
Russell emphasized the importance of analyzing language to understand logic, recognizing that philosophical confusion often stemmed from misunderstandings about language. He explored the relationship between words and the world, arguing that while language is a powerful tool, it can also be misleading, particularly in its grammatical structure. He argued that traditional philosophical approaches often mistakenly focused on words themselves rather than their meaning and connection to facts. To avoid these pitfalls, Russell advocated for the use of a logical language, one that is precise and avoids the ambiguities of ordinary language.
2.4 Beyond Formal Systems: The Limits of Logic
While Russell championed the power of logic, he also recognized its limitations, acknowledging that logic alone cannot answer all philosophical questions. He believed that empirical observation remained necessary to determine the truth of many propositions, particularly those concerning the existence of things in the world. He distinguished between logical propositions, which are tautological and true by their form, and empirical propositions, which require evidence from experience. Russell also recognized that questions of value, such as ethical judgments, lie outside the domain of logic and science, belonging instead to the realm of feeling and moral intuition.
2.5 Russell’s Philosophical Approach
Russell’s approach to philosophy can be characterized as analytical empiricism. He combined a rigorous emphasis on logical analysis with a commitment to grounding knowledge in empirical observation. This approach, seeking to disentangle complex concepts and expose fallacious reasoning, contrasted with the grand, speculative systems of traditional metaphysics. Russell believed that philosophy should proceed in a piecemeal fashion, tackling specific problems with clarity and precision, much like the scientific method. By combining logical rigor with empirical grounding, Russell revolutionized the philosophy of logic, laying the foundation for modern analytic philosophy and shaping the trajectory of philosophical inquiry in the 20th century.
3-A Look at Russell’s Engagement with the History of Philosophy
Bertrand Russell’s unique perspective on the history of philosophy is highlighted, showcasing both his deep knowledge of the subject and his critical, often irreverent, assessments of past thinkers. He saw the history of philosophy as a valuable resource for understanding the evolution of ideas but was wary of treating it as a source of immutable truths.
3.1 The Importance of Context and Avoiding Anachronism
Russell emphasizes the need to understand philosophical ideas within their historical context, recognizing that “philosophers are products of their timeand influenced by the social, political, and intellectual currents of their era.”
He criticizes the tendency to draw simplistic parallels between historical examples and contemporary issues, arguing that “the specific circumstances of ancient Greece or Rome, for example, have little relevance to modern political debates.”
This caution against anachronistic interpretations underscores his commitment to a nuanced and historically informed approach to studying the history of philosophy.
3.2 The Interplay of Philosophy and Politics
Russell argues that throughout history, philosophy has often been intertwined with politics, with philosophers advocating for particular political systems or using their theories to justify existing power structures.
He notes that certain philosophical schools have had clear connections to political ideologies, such as the link between empiricism and liberalism or idealism and conservatism.
However, he also recognizes that these connections are not always straightforward and that individual philosophers may hold views that deviate from the general trends of their school.
He cites examples like Hume, a Tory despite his radical empiricism, and T.H. Green, a Liberal despite his idealist leanings.
3.3 Critiques of Past Philosophers and Schools of Thought
Russell does not shy away from offering sharp critiques of past philosophers, even those he respects, highlighting what he sees as their flaws and limitations.
He criticizes Aristotelian logic for its formal defects, overemphasis on the syllogism, and overestimation of deduction as a form of argument.
He finds St. Thomas Aquinas lacking in a true philosophical spirit, arguing that “his commitment to predetermined conclusions derived from the Catholic faith compromised his intellectual integrity.”
He describes Hegel’s philosophy as “so odd that one would not have expected him to be able to get sane men to accept it,” criticizing its obscurity and ultimately finding it absurd.
3.4 Key Themes and Trends in the History of Philosophy
Russell identifies several recurring themes in the history of philosophy, including:
The tension between empiricism and rationalism, with some philosophers prioritizing experience as the source of knowledge while others emphasizing the role of reason and innate ideas.
The debate over the nature of reality, with materialists asserting that everything is ultimately physical while idealists posit the primacy of mind or spirit.
The search for a unified understanding of the world, often leading to the construction of grand metaphysical systems that attempt to explain everything from the nature of being to the meaning of human existence.
The relationship between philosophy and science, with some philosophers seeking to align their work with scientific methods while others view philosophy as having a distinct domain of inquiry.
The role of philosophy in guiding human conduct, with some philosophers developing ethical and political theories aimed at improving society while others focus on more abstract questions about knowledge and reality.
3.5 Championing Logical Analysis and Empiricism
Russell identifies himself as belonging to the “mathematical party” in philosophy, placing him in a lineage that includes Plato, Spinoza, and Kant.
However, he also distinguishes his approach, which he calls the “philosophy of logical analysis,” from earlier forms of rationalism.
This method, drawing on the advances in mathematical logic made by figures like Frege, Cantor, and himself, aims to eliminate “Pythagoreanism” from mathematics and ground knowledge in empirical observation.
He believes that logical analysis, combined with empiricism, offers the most promising path for achieving genuine philosophical knowledge.
3.6 The Continuing Relevance of the History of Philosophy
While Russell is critical of certain aspects of past philosophical thought, he recognizes the importance of engaging with the history of philosophy. He believes that by studying the ideas of previous thinkers, we can gain a deeper understanding of our philosophical assumptions, identify recurring patterns in intellectual history, and appreciate the complexities of philosophical inquiry. His writings on the history of philosophy are both informative and engaging, demonstrating his ability to present complex ideas in a clear and accessible manner. He encourages readers to think critically about the ideas of the past, to challenge received wisdom, and to continue the ongoing quest for philosophical understanding.
4-Bertrand Russell on Religion and Ethics: A Complex Relationship
The sources, composed primarily of Russell’s writings, reveal his critical perspective on religion and its influence on ethical thought. He views religion, particularly organized religion, as a source of harmful superstitions and an obstacle to moral progress. However, he acknowledges the human need for a sense of purpose and belonging, suggesting that a non-dogmatic “religious” outlook is possible and even desirable.
4.1 Rejection of Religious Dogma and Superstition
Russell strongly rejects religious dogma, arguing that beliefs based solely on tradition or emotion are intellectually dishonest and harmful to individual and societal well-being.
He criticizes the concept of “sin” as a superstitious notion that leads to needless suffering and inhibits rational approaches to ethical issues, especially those related to sex.
He argues that religious authorities often exploit fear and guilt to maintain power and control, discouraging critical thinking and perpetuating social injustices.
He points to the historical record of religious persecution and violence as evidence that religion has often been a force for evil rather than good.
He contends that morality should be based on reason and evidence, considering the consequences of actions and aiming to promote human happiness rather than blindly adhering to arbitrary rules.
4.2 Critiques of Christianity and its Moral Claims
Russell specifically criticizes Christianity, arguing that its doctrines are illogical, its ethical teachings are often hypocritical, and its historical record is marred by cruelty and oppression.
He challenges the notion that belief in God makes people more virtuous, pointing to examples of moral progress achieved through secular efforts and the opposition of organized religion to social reforms.
He argues that the concept of hell is incompatible with true humaneness and that the vindictive nature of some Christian teachings is morally repugnant.
He critiques the Christian emphasis on sexual repression, arguing that it leads to unnecessary suffering and psychological harm while advocating for a more rational and humane approach to sexual ethics.
4.3 The Need for a Non-Dogmatic “Religious” Outlook
While rejecting traditional religion, Russell acknowledges the human need for a sense of purpose and connection to something larger than oneself.
He suggests that a “religious” outlook is possible without belief in God or adherence to specific doctrines, proposing an ethic based on love, knowledge, and service to humanity.
He argues that this non-dogmatic “religion” would foster intellectual integrity, compassion, and a desire to understand and improve the world.
He sees the pursuit of knowledge, artistic creation, and the appreciation of beauty as sources of meaning and fulfillment that can provide a sense of the infinite without relying on supernatural beliefs.
4.5 The Role of Ethics in a Secular World
Russell believes that ethics can and should stand on its own, independent of religious authority.
He argues that moral rules should be judged by their consequences, aiming to promote human happiness and well-being rather than adhering to arbitrary or outdated codes.
He emphasizes the importance of critical thinking and individual responsibility in moral decision-making, urging people to question traditional beliefs and consider the impact of their actions on others.
He advocates for a more humane and rational approach to social issues, including crime, punishment, and sexual ethics, rejecting the vengeful and punitive attitudes often associated with religious morality.
4.6 Key Differences Between Russell’s Views and Christianity
To further clarify Russell’s perspective, it’s helpful to contrast his views with those typically associated with Christianity:
Bertrand Russell, a philosopher and advocate of secular humanism, contrasts his views on ethics and morality with traditional Christian beliefs.
Basis of Morality: According to Russell, morality should be grounded in reason, evidence, and consequences, with the goal of minimizing harm and promoting well-being. In contrast, the Christian view holds that morality is based on divine commands and scriptural authority, where following God’s will is the foundation of right and wrong.
Nature of Humans: Russell sees humans as potentially good and capable of rational thought, able to use reason to improve society and solve problems. Traditional Christianity, however, teaches that humans are inherently sinful due to original sin and are in need of redemption through divine grace.
Purpose of Life: In Russell’s view, life’s purpose is to promote happiness, pursue knowledge, and serve humanity, aiming for individual and collective flourishing. The Christian perspective centers around serving God and achieving salvation in the afterlife, making spiritual fulfillment and obedience the primary goals.
Role of Religion: Russell argues that religion can be potentially harmful, as it often relies on superstition and dogma, which may stifle critical thinking and progress. For Christians, however, religion is essential for morality, providing truth, guidance, and a framework for living a virtuous life.
Sexual Ethics: Russell advocates for sexual ethics grounded in consent, individual freedom, and well-being, emphasizing personal autonomy. By contrast, Christian sexual ethics are governed by strict rules that prioritize procreation and marital fidelity, seeing sexual behavior as something to be regulated within the context of marriage.
It is important to note that these are broad generalizations, and there are significant variations within both secular and Christian thought. However, these key differences highlight the contrasts between Russell’s secular approach and traditional Christian ethics.
5-Russell on the Philosophical Significance of Plato’s Myths
The sources primarily focus on Bertrand Russell’s own philosophical journey and do not directly address his views on the specific philosophical significance of Plato’s myths. However, based on the available information, some inferences can be drawn:
Critique of Non-Empirical Knowledge: Russell’s evolving philosophical stance, as described in the sources, indicates a strong preference for empirical knowledge and logical analysis. His “retreat from Pythagoras” [1] suggests a move away from mystical and metaphysical interpretations of reality, including those found in Plato’s work. This suggests that he might have viewed Plato’s myths as allegorical or illustrative tools rather than sources of genuine philosophical insight. He states that his strongest philosophical prejudice is “belief in the above process” of philosophical investigation, which is “just like that of watching an object approaching through a thick fog: at first it is only a vague darkness, but as it approaches articulations appear and one discovers that it is a man or a woman, or a horse or a cow or what not” [2]. It is reasonable to infer that he would not have viewed Plato’s myths as part of this “process”.
Rejection of Dogma: Russell consistently criticized the use of dogma and unquestioned authority in philosophy and other areas of human thought. He argued against accepting any system of beliefs, including religious or political ideologies, without rigorous examination and justification [3]. Given Plato’s use of myths to reinforce his philosophical arguments, Russell might have seen them as attempts to bypass critical thinking and appeal to emotion or tradition rather than reason. He directly states that “burning schools, or men for that matter, has always proved singularly unhelpful in stamping out unorthodoxy” [4]. It is reasonable to infer that Russell may have found Plato’s use of myths to support his potentially dogmatic worldview similarly “unhelpful”.
Emphasis on Clarity and Precision: Russell valued clarity, precision, and logical rigor in philosophical discourse. He advocated for the use of precise language and the avoidance of vague or ambiguous terms [5]. He explicitly states: “I like precision. I like sharp outlines. I hate misty vagueness” [6]. Given the symbolic and often ambiguous nature of myths, it is likely that he would have favored philosophical arguments that relied on clear and well-defined concepts rather than the open-ended interpretations invited by mythical narratives.
Historical Context: Russell was deeply interested in the history of philosophy and acknowledged Plato’s significant influence on Western thought [6, 7]. He recognized the importance of understanding philosophical ideas within their historical contexts, suggesting that he would have approached Plato’s myths with an awareness of their historical significance and their role in shaping subsequent philosophical debates.
While the sources do not explicitly state Russell’s views on Plato’s myths, his overall philosophical approach suggests that he might have viewed them with a degree of skepticism, preferring philosophical arguments grounded in logic, empirical evidence, and clear language over those that relied on symbolism and allegory.
Note: It is important to remember that these are inferences based on Russell’s general philosophical orientation and the limited information provided in the sources. Further research into Russell’s writings on Plato might reveal more specific and nuanced perspectives on this topic.
6-The Impact of World War I on Russell’s Political Views: A Profound Shift Towards Pacifism and Activism
While the sources do not provide a comprehensive account of Russell’s experiences during World War I, they do offer glimpses into how the war profoundly impacted his political views, leading to a passionate commitment to pacifism and activism, a departure from his earlier, more theoretical, approach to politics.
A War for Freedom and Democracy? The Harsh Realities: In his autobiographical reflections, Russell expresses his staunch opposition to World War I, viewing it as a “folly and a crime” on the part of all the participating nations. He challenges the prevailing narratives that justified the war as a fight for freedom, democracy, and against militarism, arguing that the war’s aftermath actually resulted in a decline in freedom, a surge in militarism, and an uncertain future for democracy [1]. This disillusionment with the purported ideals of the war fueled his commitment to pacifism and his efforts to expose the true nature of the conflict.
The Devastating Consequences of Violence: Russell was deeply affected by the immense human suffering caused by the war, particularly the senseless loss of young lives. This experience forced him to confront the brutal realities of war, shattering the abstract world of ideas he had previously inhabited [2]. He recounts witnessing young men being sent off to die on the battlefields because of incompetent generals, an experience that filled him with “aching compassion” and solidified his commitment to finding ways to prevent future wars [1].
The Failure of the Versailles Treaty: Russell’s hopes for a lasting peace based on reason and a commitment to avoiding future wars were dashed by the Versailles Treaty, which he believed sowed the seeds for further conflict by imposing harsh punishments on Germany [1]. This experience reinforced his conviction that traditional power politics and punitive measures were ultimately counterproductive and that a new approach to international relations was urgently needed.
A Focus on Educational Reform: The war also led Russell to recognize the role of education in shaping political attitudes and fostering destructive emotions like hatred and fear. He became increasingly interested in educational reform, believing that a more enlightened and humane education system could help prevent future conflicts by cultivating critical thinking, empathy, and a global perspective [3, 4].
The impact of World War I on Russell’s political views was profound and lasting. It led him to:
Embrace Pacifism and Activism: The war transformed Russell from a primarily academic philosopher to a vocal pacifist and political activist, willing to challenge the status quo and risk social ostracism for his beliefs [1]. He actively campaigned against the war, facing imprisonment and public condemnation for his stance.
Champion Internationalism: Disillusioned by the failure of traditional power politics and the destructive nationalism that fueled the war, Russell became a strong advocate for internationalism and the creation of a world government capable of preventing future wars [5, 6]. He believed that only a supranational authority with the power to enforce international law could effectively address the growing threat of global conflict.
Emphasize the Importance of Psychology in Politics: The war heightened Russell’s awareness of the powerful role that emotions, particularly fear and hatred, play in political decision-making [7]. He argued that understanding these psychological drivers was crucial for developing effective political strategies and creating a more peaceful and just world.
In conclusion, World War I marked a turning point in Russell’s intellectual and political life. It pushed him to move beyond the abstract realm of philosophical theory and engage directly with the pressing social and political issues of his time. The war’s devastating consequences, the failure of traditional approaches to peace, and his own experiences with persecution for his pacifist views led him to dedicate much of his subsequent work to advocating for a more peaceful, just, and internationally cooperative world order.
7-From Mathematical Certainty to Empirical Probability: The Evolution of Bertrand Russell’s Views on Knowledge
Bertrand Russell’s views on the nature of knowledge underwent a significant transformation throughout his long philosophical career, moving from an early emphasis on mathematical certainty to a later embrace of empirical probability and the limitations of human understanding. This evolution was shaped by his engagement with various philosophical schools, his groundbreaking work in logic and mathematics, and his growing awareness of the complexities of the relationship between language, perception, and the world.
Early Influences: The Quest for Logical Foundations and the Appeal of “Mysticism and Logic”
Mathematical Roots: Russell’s initial foray into philosophy was deeply influenced by his background in mathematics. He sought to apply the rigor and certainty of mathematical reasoning to philosophical problems, particularly in his early work on the foundations of mathematics and logic, as exemplified in Principia Mathematica [1]. This led him to believe that philosophical knowledge, like mathematical knowledge, could be grounded in self-evident axioms and logical deduction [2]. His early fascination with mathematical logic is evident in his statement: “In this change of mood, something was lost, though something also was gained. What was lost was the hope of finding perfection and finality and certainty” [3]. He initially believed that mathematical logic held the key to unlocking this “perfection and finality and certainty”.
“Mysticism and Logic”: During this early period, Russell was drawn to a form of “mysticism” that he saw as compatible with logic. As he later described it, this involved a belief in the profound emotional and intellectual satisfaction derived from contemplating the logical structure of the world [3]. This outlook is reflected in his famous essay “A Free Man’s Worship,” where he finds solace in the face of a meaningless universe by embracing the beauty and power of the human intellect [4]. However, he later came to distance himself from this perspective, recognizing its limitations and potential for obscuring the complexities of human experience.
The Shift Towards Empiricism and the Importance of Sense Data
Growing Skepticism of A Priori Knowledge: As Russell’s philosophical thinking matured, he became increasingly skeptical of the possibility of attaining certain knowledge through a priori reasoning alone. His engagement with the work of empiricist philosophers like John Locke and David Hume led him to emphasize the importance of sense experience as the foundation of knowledge [5, 6].
The Centrality of Sense Data: Russell developed the concept of “sense data” as the fundamental building blocks of our knowledge of the external world. He argued that our direct awareness is not of physical objects themselves, but of the sensory experiences they produce in us. These sense data, while subjective in nature, provide the raw material from which we construct our understanding of the world [6, 7]. This shift is clearly reflected in his statement: “I think of sense, and of thoughts built on sense, as windows, not as prison bars” [8]. He moved away from seeing sense experience as a limitation and towards seeing it as the foundation of our understanding of the world.
The Limits of Language and the Problem of Vagueness
The Influence of Language: Russell recognized the profound influence of language on our thinking about knowledge and reality. He explored the relationship between language and the world, analyzing the ways in which language can both illuminate and obscure our understanding of reality.
The Problem of Vagueness: He paid particular attention to the problem of vagueness in language, arguing that many philosophical problems arise from our uncritical use of vague and ambiguous terms [9, 10]. He advocated for the use of precise language and logical analysis to clarify the meaning of philosophical concepts, thus avoiding the traps of metaphysical speculation. He even lamented the loss of certainty that came with this approach, stating: “What was gained was a new submission to some truths which were to me repugnant” [3].
The Embrace of Probability and the Importance of Non-Demonstrative Inference
The Limits of Deductive Logic: While Russell made groundbreaking contributions to deductive logic, he increasingly recognized its limitations in accounting for the vast majority of human knowledge. He acknowledged that most of our beliefs, including those in science and everyday life, are based on non-demonstrative inference, where the conclusions are probable rather than certain [2, 11].
The Role of Induction and Analogy: Russell explored the role of induction, analogy, and other forms of non-demonstrative reasoning in expanding our knowledge beyond the limits of direct experience. He recognized the inherent uncertainty involved in these forms of inference, but argued that they were essential for scientific progress and for navigating the complexities of the world [12, 13].
The Later Years: A Balanced Perspective on Knowledge
Humility and Openness to Revision: In his later work, Russell adopted a more pragmatic and nuanced view of knowledge. He emphasized the fallibility of human understanding, the importance of remaining open to new evidence, and the need for constant revision of our beliefs in light of new discoveries. He states that “in philosophy, though not in science, there are those who make such changes [in opinions] a matter of reproach” and that “for my part, I should regard an unchanging system of philosophical doctrines as proof of intellectual stagnation” [14]. This statement reveals his commitment to intellectual humility and the ongoing pursuit of knowledge.
The Interplay of Sense Data, Logic, and Scientific Inquiry: Russell’s mature epistemology synthesized his earlier emphasis on sense data with his recognition of the crucial role of logic and scientific inquiry in shaping our understanding of the world. He saw knowledge as arising from the complex interplay of these elements, with each contributing to the ongoing process of refining our understanding of reality.
In conclusion, Bertrand Russell’s views on the nature of knowledge evolved significantly throughout his life. He moved from an initial focus on mathematical certainty to a more nuanced understanding of the role of sense experience, the limitations of language, and the importance of non-demonstrative inference in shaping our knowledge of the world. His journey reflects a deep commitment to the pursuit of truth, a willingness to challenge his own assumptions, and an enduring belief in the power of reason to illuminate our understanding of ourselves and the universe.
8-The Evolution of Bertrand Russell’s Political Views: A Journey From Aristocratic Liberalism to Outspoken Activism
Bertrand Russell’s political journey was marked by significant shifts in ideology, reflecting both his personal experiences and the changing world around him. The sources reveal a trajectory from traditional aristocratic liberalism in his youth to a more radical and activist stance in later life, fueled by his experiences during World War I and his evolving understanding of power dynamics and human psychology.
Early Influences: The Roots of Aristocratic Liberalism
Family Legacy and Whig Principles: Born into a prominent aristocratic family steeped in political tradition, Russell’s early political outlook was heavily influenced by the Whig principles of his upbringing [1, 2]. His grandfather, Lord John Russell, a prominent Whig politician who served as Prime Minister, instilled in him a belief in gradual social progress, parliamentary government, and the importance of individual liberty. This aristocratic liberalism assumed that a benevolent elite, guided by reason and experience, would naturally lead society towards a better future.
Early Skepticism of Force and Imperialism: Despite his initial embrace of Whig ideology, Russell’s evolving worldview led him to question certain aspects of this inherited political framework. In 1896, he published his first book, German Social Democracy, which demonstrated his early interest in economic and political systems beyond the traditional British model. By 1901, he had completely abandoned his support for imperialism, developing a deep aversion to the use of force in human relations. He actively participated in the movement for women’s suffrage, further demonstrating his commitment to expanding democratic principles [3].
The Turning Point: World War I and the Embrace of Pacifism
The Folly of War and the Illusion of National Interest: As discussed in our previous conversation, World War I marked a profound turning point in Russell’s political views. His experience of the war’s devastating consequences, the pervasive propaganda that masked its true nature, and his own persecution for his pacifist stance led him to reject the traditional justifications for war and embrace a commitment to pacifism [4]. He saw the war as a colossal failure of reason and a testament to the destructive power of nationalism, challenging the notion that war could ever truly serve the interests of humanity.
Post-War Activism: Challenging Dogma and Power Structures
Critique of Totalitarian Regimes: The rise of totalitarian regimes in the interwar period further solidified Russell’s commitment to individual liberty and democratic principles. He was a vocal critic of both fascism and communism, seeing them as dangerous ideologies that suppressed individual freedom and led to tyranny. He argued that any system that concentrated power in the hands of a few, regardless of its ideological label, inevitably led to corruption and abuse [5]. This skepticism of concentrated power is further evidenced in his analysis of Marxism, which he found to be overly deterministic and potentially leading to societal stagnation [6].
Focus on the Psychology of Power: Russell’s analysis of power dynamics increasingly incorporated insights from psychology, recognizing the role of emotions like fear, hatred, and vanity in driving political behavior [7]. He argued that understanding these psychological factors was crucial for developing effective strategies to mitigate conflict and promote cooperation. This is evident in his analysis of how propaganda exploits fear and hatred to manipulate public opinion and justify violence.
The Need for a World Government: Haunted by the specter of future wars made even more devastating by technological advances, Russell became a strong advocate for world government as the only viable solution to the problem of international anarchy [8]. He believed that a supranational authority with the power to enforce international law was essential to prevent future conflicts and ensure the survival of humanity in the nuclear age. He argued that the increasing interconnectedness of the world, particularly in the economic realm, made a global approach to governance not only desirable but necessary [9].
Later Years: A Blend of Pragmatism and Idealism
Recognizing the Limits of Power and the Importance of Individual Freedom: While acknowledging the need for some form of global governance to address the challenges of the nuclear age, Russell never wavered in his commitment to individual liberty. He cautioned against the dangers of concentrating too much power in any single entity, even a world government, arguing that safeguards were needed to protect individual freedoms and prevent the emergence of a new form of tyranny [10].
Continuing to Challenge Conventional Wisdom: Throughout his life, Russell remained a vocal critic of social and political injustice, using his platform to advocate for peace, nuclear disarmament, and human rights. He continued to challenge conventional wisdom and speak truth to power, even when his views were unpopular or controversial.
In conclusion, Bertrand Russell’s political views underwent a significant transformation throughout his life. While his early upbringing instilled in him a belief in gradual social progress and liberal values, his experiences during World War I and his evolving understanding of power dynamics and human psychology led him to embrace a more radical and activist stance, advocating for pacifism, internationalism, and the need to constrain the destructive potential of both individual and state power. His political thought, while evolving, remained consistently grounded in a deep concern for human well-being and a commitment to using reason and critical analysis to create a more just and peaceful world.
Russell’s Early Interest in Philosophy: A Search for Certainty
The sources suggest that Bertrand Russell’s early interest in philosophy was primarily driven by a profound desire to find knowledge that could be accepted as certainly true. This pursuit of certainty was sparked by a childhood experience with geometry that left a lasting impression on him [1, 2].
The Disillusionment of Geometry: At the age of eleven, Russell was introduced to Euclid’s geometry by his brother. Initially excited by the prospect of finding a system of knowledge that “proved things,” he was profoundly disappointed to learn that geometry rested upon axioms that could not themselves be proven. This early encounter with the limitations of deductive certainty left him questioning the foundations of knowledge and yearning for a more secure basis for belief [1, 2].
Seeking a Foundation for Mathematical Beliefs: This early experience fueled Russell’s interest in the principles of mathematics and his search for a way to refute mathematical skepticism. He was dissatisfied with arguments that he found to be fallacious and sought a more solid foundation for mathematical knowledge. This quest led him to increasingly abstract areas of study, eventually leading him to mathematical logic, which he initially viewed as a means of securing the certainty he craved [2].
This desire for certainty extended beyond mathematics, influencing his early engagement with religion and metaphysics:
Questioning Religious Dogma: Despite a strong desire to preserve some form of religious belief, Russell’s skepticism led him to question the fundamental dogmas of religion, meticulously examining them one by one in search of rational justification. This exploration resulted in an early embrace of agnosticism, which he maintained throughout his life [2].
Finding Temporary Solace in Hegelianism: At Cambridge, Russell was introduced to Hegelian philosophy. Initially, he found comfort in its promise of a unified and meaningful universe. However, his direct study of Hegel’s work revealed a “farrago of confusions,” ultimately leading him to abandon this philosophical system [3].
The sources make it clear that Russell’s early interest in philosophy was sparked by a deep-seated need to find a secure foundation for knowledge, a need born from his encounter with the limits of deductive certainty in geometry and his struggle to reconcile his religious impulses with his skeptical mind. This pursuit of certainty would continue to shape his philosophical journey, even as his views evolved and his understanding of the nature of knowledge became more nuanced over time.
10-Russell’s Evolving Philosophical Interests: A Journey From Certainty to Humility
The sources offer a compelling narrative of Bertrand Russell’s shifting philosophical interests throughout his long and intellectually vibrant life. His journey is characterized by an initial fervent search for absolute certainty, followed by a gradual embrace of a more humble, piecemeal approach to knowledge, deeply influenced by his evolving understanding of logic, mathematics, and the empirical sciences.
Early Quest for Indisputable Truth
The Disillusionment of Geometry: Russell’s early interest in philosophy was ignited by a yearning for certain, demonstrably true knowledge [1]. At the tender age of eleven, he was deeply disappointed to learn that the axioms of Euclidean geometry, which he believed “proved things,” were themselves unprovable assumptions [1, 2]. This early encounter with the limits of deductive certainty planted a seed of doubt that would continue to influence his intellectual journey.
Seeking Solace in Metaphysics: Driven by his need for certainty and a desire to reconcile his religious impulses with his burgeoning skepticism, Russell initially turned to metaphysics, hoping to find philosophical proofs for the existence of God and other comforting truths [3-5] . He found temporary solace in Hegelian philosophy, attracted to its promise of a unified, meaningful universe where everything was interconnected and spirit ultimately triumphed over matter [6]. However, his direct engagement with Hegel’s work revealed a “farrago of confusions” that ultimately led him to abandon this philosophical system [6].
The Turning Point: Embracing Mathematical Logic
A New Tool for Philosophical Inquiry: Russell’s immersion in mathematical logic marked a turning point in his philosophical development [7-11]. His collaborative work on Principia Mathematica with Alfred North Whitehead, aiming to reduce mathematics to its logical foundations, not only revolutionized mathematics but also profoundly influenced his approach to philosophical questions [7, 12, 13].
From Grand Systems to Precise Analysis: The rigor and precision of mathematical logic led Russell to shift his focus from grand metaphysical systems to a more piecemeal approach, tackling specific philosophical problems with analytical clarity [2, 11, 14, 15]. He embraced a more scientific, evidence-based approach to philosophical inquiry, inspired by the successes of empirical sciences and their ability to make progress through careful observation, experimentation, and logical reasoning [16-18].
Later Years: Acknowledging the Limits of Knowledge
The Importance of Non-Demonstrative Inference: In his later work, Russell increasingly recognized the limitations of deductive logic, acknowledging that most real-world inferences, both in science and everyday life, are non-demonstrative, leading to conclusions that are probable rather than certain [19-21]. This realization led him to explore the nature of probability and inductive reasoning, seeking to understand how we can arrive at reliable knowledge even in the absence of absolute certainty [21].
From Asceticism to Embracing Experience: Russell’s early attraction to a timeless, unchanging Platonic realm gradually gave way to a more balanced view that acknowledged the importance of the sensory world and human experience [22]. He described this shift as a “retreat from Pythagoras,” abandoning his earlier asceticism and embracing a more nuanced understanding of the relationship between mind and matter, sense and intellect [10]. He came to see the senses and thoughts based on sensory experience as “windows, not as prison bars,” recognizing the importance of grounding philosophical inquiry in the richness and complexity of the lived world [22].
Continuing Engagement with Social and Political Issues: While his focus shifted increasingly towards logic and the philosophy of science, Russell never abandoned his engagement with social and political issues [23-25]. He continued to write and speak out on matters of war, peace, education, ethics, and human rights, applying his philosophical insights to address the pressing problems of his time [7, 23, 26-31].
In conclusion, the sources reveal a dynamic and evolving philosophical journey, marked by an early quest for certainty, a transformative engagement with mathematical logic, and a later embrace of a more nuanced and humble understanding of the limits and possibilities of human knowledge. Throughout his life, Russell remained committed to a scientific approach to philosophical inquiry, seeking to clarify complex ideas, challenge dogma, and contribute to a more rational and just world.
11-Divergent Visions: Contrasting Russell and Dr. Arnold’s Educational Philosophies
Bertrand Russell’s views on education stand in stark contrast to those of Dr. Thomas Arnold, the influential headmaster of Rugby School in 19th-century England. While both men recognized the power of education in shaping individuals and society, their fundamental goals and approaches diverged significantly.
The Purpose of Education: Russell viewed education primarily as a means of cultivating well-rounded individuals capable of contributing to human flourishing and societal progress. He emphasized the importance of fostering intellectual curiosity, critical thinking, and a love of knowledge, arguing that education should equip individuals to lead fulfilling and purposeful lives beyond mere economic or nationalistic goals.
In contrast, Dr. Arnold’s educational philosophy was deeply rooted in the cultivation of “virtuous” Christian gentlemen who would uphold traditional social hierarchies and serve as leaders within the British Empire. He prioritized the development of character traits such as discipline, obedience, and loyalty, emphasizing religious instruction and the inculcation of moral principles based on Christian beliefs.
The Role of the Individual: Russell championed individuality and independent thought, arguing that education should foster critical thinking, a scientific mindset, and the courage to challenge accepted norms. He criticized systems that prioritize obedience and conformity, believing that these traits stifle creativity and hinder intellectual progress.
Dr. Arnold, on the other hand, believed in shaping students according to a predetermined mold of “ideal” Christian manhood. He emphasized the importance of instilling a strong sense of duty, discipline, and adherence to established authority, believing that these qualities were essential for maintaining social order and upholding the values of the British elite.
The Ideal Citizen: Russell envisioned education as a means of creating wise citizens of a free community, capable of contributing to a more just, compassionate, and enlightened world. He emphasized the importance of fostering a global perspective, encouraging international cooperation, and promoting peace over conflict.
Dr. Arnold’s vision of the ideal citizen was more narrowly focused on service to the British Empire and the perpetuation of its power and influence. He believed that education should produce leaders who were imbued with a sense of national pride, unwavering loyalty to the Crown, and a willingness to defend British interests at home and abroad.
The Curriculum: Russell advocated for a broad and balanced curriculum that included the humanities, sciences, and arts, emphasizing the interconnectedness of knowledge and the importance of cultivating a wide range of intellectual interests. He believed that education should foster a love of learning for its own sake, not merely as a means to an end.
Dr. Arnold’s curriculum focused heavily on classical studies, religious instruction, and physical discipline, reflecting his belief that these subjects were essential for shaping the character and intellect of future leaders. While he recognized the importance of some scientific and mathematical education, his primary emphasis remained on the traditional subjects that had long formed the foundation of British elite education.
These contrasting visions reflect fundamental differences in their social and political contexts. Russell, writing in the early 20th century, was deeply critical of the nationalism, imperialism, and social inequalities that had fueled global conflict and sought to promote a more just and peaceful world through education. Dr. Arnold, writing in the 19th century, was a product of a time when Britain was at the height of its imperial power and his educational philosophy reflected the values and priorities of the ruling class.
While Dr. Arnold’s legacy continues to influence certain aspects of British education, particularly in the emphasis on character development and public service, Russell’s ideas have had a broader impact on modern educational thought, inspiring progressive approaches that prioritize individual growth, critical thinking, and a commitment to social justice. The source material focuses on Russell’s perspectives, making direct comparisons challenging without further information on Dr. Arnold’s specific views on education. [1, 2]
12-A Teacher’s Purpose: Cultivating Vital Citizens of a Free Community
According to Bertrand Russell, the main purpose of a teacher is to cultivate individuals who can become vital citizens of a free community, contributing to human betterment through their knowledge, compassion, and independent thought. This role extends beyond simply imparting information; it encompasses nurturing the emotional and intellectual development of students, fostering their capacity for independent thought, and instilling a sense of responsibility towards humanity.
The sources, particularly “The Functions of a Teacher” [1], articulate Russell’s view of the teacher’s purpose as a multifaceted endeavor crucial for societal progress. He argues that a teacher’s primary function is to:
Instill Knowledge and Reasonableness: Teachers play a vital role in shaping public opinion by instilling knowledge and encouraging a rational approach to understanding the world [1]. They introduce students to different fields of study, nurturing intellectual curiosity and equipping them with the tools to evaluate information critically and form their own judgments.
Counteract Harmful Beliefs and Prejudices: Russell emphasizes the teacher’s duty to combat ignorance and prejudice, promoting open-mindedness and a willingness to challenge accepted norms [1, 2]. They should present a wide range of perspectives, encouraging students to question their assumptions and engage in constructive dialogue.
Cultivate Desirable Emotional Dispositions: Russell believes that a good teacher not only imparts knowledge but also shapes the emotional development of their students [3]. They should foster compassion, empathy, and a concern for the well-being of others, encouraging students to develop the emotional maturity to navigate complex social interactions and contribute to a more just and harmonious society.
Promote Individual Growth and Creativity: Russell sees education as a means of “nourishing” a student’s own growth, not merely molding them into a pre-determined shape [4]. He argues that good teachers encourage individuality and creativity, celebrating the unique talents and interests of each student and fostering their capacity for independent thought and action.
Inspire a Sense of Responsibility Towards Humanity: Russell believes that teachers should instill in their students a sense of responsibility towards humanity, encouraging them to use their knowledge and skills for the betterment of society [3]. They should help students understand their place in the world, fostering a sense of global citizenship and encouraging them to contribute to the advancement of human progress.
In essence, Russell views teaching as a profession of profound social and ethical importance, entrusted with shaping the minds and hearts of future generations. He believed that good teachers act as guides and mentors, helping students develop into individuals who are not only knowledgeable and skilled, but also compassionate, responsible, and capable of contributing to a more just and enlightened world.
13-The Foundation of Good Teaching: A Deep and Genuine Affection for Students
According to Bertrand Russell, the most important characteristic of a good teacher is a deep and genuine affection for their students. This foundational quality underpins many other desirable traits and is crucial for creating a learning environment where students can thrive intellectually and emotionally.
The sources repeatedly highlight Russell’s belief that love for students, both individually and collectively, is essential for effective teaching. He argues that this affection goes beyond mere professional duty or a desire to impart knowledge; it involves:
Seeing Students as Ends in Themselves: Russell criticizes educators who view students primarily as instruments for achieving external goals, whether those goals be nationalistic, economic, or ideological. He emphasizes that good teachers must see their students as ends in themselves, recognizing their inherent worth and respecting their individual potential (, , ).
Wanting the Best for Students: Just as a loving parent desires the best for their child, good teachers genuinely care about the well-being and development of their students. They want their students to flourish intellectually, emotionally, and socially, and their teaching is motivated by a sincere desire to help them achieve their full potential (, ).
Fostering a Positive Learning Environment: A teacher’s affection for their students manifests in the creation of a positive and supportive learning environment. They approach teaching with enthusiasm and a genuine desire to share their love of knowledge, fostering a sense of joy and excitement in the learning process. They are patient and understanding, recognizing that students learn at different paces and encouraging them to embrace challenges without fear of failure (, , ).
Inspiring Trust and Respect: Students are more likely to trust and respect teachers who genuinely care about them. This trust creates a foundation for open communication and encourages students to take risks, ask questions, and engage actively in the learning process. When students feel respected and valued, they are more likely to be receptive to new ideas and motivated to learn.
This emphasis on affection as a core characteristic of good teaching aligns with Russell’s broader educational philosophy, which prioritizes individual growth, intellectual freedom, and the cultivation of desirable emotional dispositions. He argues that teachers who possess this quality are better equipped to:
Resist the Urge to Dominate: Russell cautions against the dangers of educators who prioritize control and obedience, viewing students as mere objects to be manipulated. He argues that a genuine affection for students helps teachers to resist this temptation, fostering independence of thought and encouraging students to develop their own judgments (, ).
Encourage Individuality and Creativity: A loving teacher celebrates the unique talents and interests of each student, encouraging their creativity and fostering their individuality. They recognize that true learning flourishes in an environment where students feel safe to express themselves and explore their passions.
Inspire a Love of Learning: Teachers who approach their subject matter with passion and enthusiasm can ignite a love of learning in their students. When students see that their teacher genuinely cares about their subject, they are more likely to be drawn in and motivated to learn.
Russell’s emphasis on the importance of a teacher’s affection for their students serves as a powerful reminder that effective teaching is not merely about transmitting information but about fostering human connection and nurturing individual growth. He believed that this foundational quality is essential for creating a learning environment where students can develop into independent, compassionate, and intellectually engaged individuals.
14-Education for a World Beyond Domination: Cultivating Individuals Capable of Contributing to Human Flourishing
Bertrand Russell believes the most important aim of education is to cultivate individuals who value and contribute to human flourishing, moving beyond a narrow focus on personal gain or nationalistic ambitions. This overarching goal underpins his various criticisms of traditional education and informs his vision for a more enlightened approach to fostering individual growth.
The sources consistently emphasize Russell’s belief that education should not merely serve as a tool for social control or economic advancement, but rather as a means of empowering individuals to lead fulfilling and purposeful lives. He argues that true human progress hinges on cultivating individuals who possess certain key characteristics, including:
A Love of Knowledge: Russell considers intellectual curiosity and a genuine desire to learn as essential for individual growth and societal progress. He laments the widespread “hatred of knowledge” among civilized mankind, attributing it to traditional teaching methods that rely on punishment and rote memorization (, ). He argues that education should foster a “joy of mental adventure” by presenting challenges that are both engaging and attainable, associating learning with the pleasure of discovery rather than the fear of failure (, ).
Open-mindedness and a Scientific Attitude: Russell champions the development of open-mindedness, the ability to consider new ideas and challenge existing beliefs in light of evidence. He criticizes the tendency to cling to dogmas and prejudices, emphasizing the importance of fostering a scientific mindset that values critical thinking, skepticism, and a willingness to revise one’s views based on reason and observation (, , ). He argues that education should equip individuals to navigate a world of competing perspectives and complex issues, fostering the ability to evaluate information critically and form independent judgments.
Courage and Compassion: Russell stresses the importance of cultivating individuals who possess both moral and intellectual courage. He criticizes educational systems that prioritize obedience and conformity, arguing that these traits stifle individuality and hinder the pursuit of truth. He believes that education should foster the courage to challenge injustice, resist harmful social pressures, and stand up for one’s convictions, even in the face of opposition (, ). He also emphasizes the importance of compassion, arguing that education should promote empathy, kindness, and a concern for the well-being of others, transcending narrow self-interest and nationalistic prejudices (, ).
A Broad Perspective and a Sense of Purpose: Russell believes that education should foster a broad perspective, encompassing an understanding of history, science, and the interconnectedness of the world. He argues that individuals should be aware of the vastness of time and space, the achievements and follies of past generations, and the challenges and possibilities of the present. This awareness, he argues, helps to cultivate a sense of humility, a recognition of the limitations of human knowledge, and an appreciation for the ongoing quest for understanding (, , ). He also believes that education should help individuals discover a sense of purpose beyond personal ambition or material gain, inspiring them to contribute to something greater than themselves and work towards a better future for all.
In essence, Russell views education as a process of liberation and empowerment, enabling individuals to break free from the shackles of ignorance, fear, and prejudice and contribute meaningfully to human progress. He emphasizes the importance of nurturing intellectual curiosity, fostering critical thinking, cultivating desirable emotional dispositions, and instilling a sense of purpose that extends beyond narrow self-interest. This vision of education challenges traditional notions of schooling, advocating for an approach that prioritizes individual growth and the development of citizens capable of contributing to a more just, compassionate, and enlightened world.
15-A Holistic Approach to Education: Fostering Individual Growth and a Reverent Attitude
Bertrand Russell’s philosophy of education centers on nurturing the individual’s intellectual and emotional development while cultivating a profound respect for the inherent potential within each child. He criticizes traditional education systems that prioritize obedience and rote learning, advocating instead for an approach that emphasizes freedom of thought, critical inquiry, and the cultivation of desirable emotional dispositions. The sources provide a comprehensive overview of his educational vision, highlighting key principles and offering insights into his criticisms of conventional educational practices.
Here are the core tenets of Russell’s educational philosophy:
Reverence for the Individual: Russell emphasizes the importance of approaching education with a sense of reverence for the child’s individuality and inherent worth (). He criticizes educators who view children as malleable objects to be molded according to preconceived ideals, arguing that such an approach stifles creativity, fosters resentment, and ultimately leads to unhappiness (). He advocates for recognizing the “something sacred, indefinable, unlimited” within each child, fostering their unique potential rather than imposing external expectations ().
Freedom of Thought and Critical Inquiry: Russell champions freedom of thought as essential for intellectual growth and the development of a truly educated citizenry. He criticizes educational systems that prioritize indoctrination and the uncritical acceptance of traditional beliefs, particularly those with a theological basis. He argues that concealing truths deemed “unedifying” weakens moral character and hinders the ability to navigate the complexities of the real world (). He advocates for fostering a scientific mindset, encouraging students to question assumptions, evaluate evidence, and form their own judgments based on reason and critical analysis (, ).
Cultivating Desirable Emotional Dispositions: Russell recognizes the crucial role of emotions in shaping individual character and behavior, arguing that education should prioritize the cultivation of desirable emotional traits such as courage, kindness, and intellectual curiosity. He criticizes the use of fear and punishment as primary motivators, arguing that these methods instill a sense of timidity and hinder intellectual exploration (, ). He advocates for creating learning environments that foster positive associations with knowledge and encourage students to embrace challenges with enthusiasm and a sense of adventure (, ).
Education for Citizenship in a Globalized World: Recognizing the increasing interconnectedness of the world, Russell emphasizes the importance of education for global citizenship. He criticizes the narrow nationalism that often permeates educational curricula, advocating for a broader perspective that recognizes the shared humanity of all people and the importance of international cooperation. He calls for a curriculum that incorporates world history from an impartial standpoint and fosters an understanding of the interdependence of different cultures and nations (). He believes education should equip students to navigate the complexities of a globalized world, fostering a sense of responsibility for creating a more just and peaceful future.
The Teacher as a Facilitator of Growth: Russell places great importance on the role of the teacher, envisioning them not as authoritarian figures but as facilitators of growth and intellectual exploration. He argues that effective teachers must possess a deep love for their subject matter, a genuine affection for children, and a commitment to fostering a stimulating and engaging learning environment (). He criticizes the emphasis on administrative tasks and hierarchical structures within educational systems, arguing that these often prioritize bureaucratic efficiency over the quality of teaching and learning ().
Russell’s philosophy of education offers a compelling vision for nurturing individual growth, fostering critical thinking, and preparing students to engage meaningfully with a complex and ever-changing world. His emphasis on reverence for the individual, freedom of thought, and the cultivation of desirable emotional dispositions provides a framework for creating educational experiences that empower students to become informed, compassionate, and engaged citizens.
16-Russell’s Path to Agnosticism: A Journey Guided by Reason and Influenced by Mill
Bertrand Russell’s loss of belief in God wasn’t a sudden event but rather a gradual process driven by his intellectual development and a critical examination of traditional religious arguments. The sources, particularly his autobiographical writings, offer insights into this journey, emphasizing the influence of philosopher John Stuart Mill and Russell’s growing reliance on reason and logical analysis.
Early Doubts and the Search for Certainty: As a young boy, Russell already exhibited a penchant for logical reasoning, seeking knowledge that could be proven with certainty, as seen in his early fascination with geometry (). His initial foray into religion was marked by a desire to find a belief system that could withstand such scrutiny. However, he found himself questioning the core tenets of Christianity, grappling with doubts about fundamental dogmas like the existence of God and the concept of an afterlife (, ).
The Turning Point: Mill’s Critique of the First-Cause Argument: A pivotal moment in Russell’s journey occurred at the age of eighteen when he encountered John Stuart Mill’s Autobiography (). Mill’s straightforward rejection of the First-Cause argument, which posits God as the ultimate cause of the universe, resonated deeply with Russell. He realized that this argument, which he had previously accepted, was fundamentally flawed. If everything required a cause, then God, too, would need a cause, leading to an infinite regress (, , ). This realization undermined a key pillar of his belief in a deity and set him on a path towards agnosticism.
Embracing Reason and Rejecting Emotional Arguments: Russell’s approach to religion was characterized by a commitment to reason and a rejection of arguments based solely on emotion or personal comfort. In “Why I Am Not a Christian,” he systematically dismantles traditional arguments for God’s existence, including those based on natural law, design, and morality. He argues that these arguments are often rooted in flawed logic, wishful thinking, and a desire for security rather than sound evidence (, ). He also criticizes the reliance on the perceived moral authority of figures like Jesus Christ, arguing that their teachings often contain inconsistencies and, in some cases, promote fear and intolerance (, ).
Finding Meaning in a Godless Universe: While rejecting traditional religious beliefs, Russell did not abandon the search for meaning and purpose. He advocated for a humanistic worldview that emphasized human reason, compassion, and the pursuit of knowledge. He found inspiration in the vastness of the universe and the potential for human progress, arguing that we have the power to shape our own destiny and create a more just and fulfilling world without relying on supernatural beliefs (, , , ).
The sources consistently portray Russell’s loss of faith as a product of his intellectual honesty, his commitment to reason, and his willingness to challenge accepted beliefs. This journey was influenced by philosophical giants like Mill and his own rigorous application of logic and critical analysis to the fundamental questions of human existence.
17-Beyond the Realm of Philosophy: Bertrand Russell’s Diverse Intellectual Pursuits
While renowned for his contributions to philosophy, Bertrand Russell’s intellectual curiosity extended far beyond this domain, encompassing a wide array of subjects that reflected his deep engagement with the human condition and the complexities of the modern world. The sources highlight his prolific writing and lecturing on topics ranging from history and politics to science and education, revealing a multifaceted thinker who sought to apply reason and critical analysis to a broad spectrum of human concerns.
Here’s a glimpse into the diverse topics Russell explored outside of his core philosophical work:
History and Its Significance: Russell believed history held profound importance, not just for academics but for all educated individuals. He argued that understanding the past provides a crucial context for navigating the present and envisioning the future, emphasizing the need to learn from past mistakes and recognize the impermanence of even the most cherished beliefs (). He himself wrote extensively on historical subjects, including The Problem of China (1922), Freedom and Organization, 1814–1914 (1934), and A History of Western Philosophy (1945) (). These works showcase his analytical approach to historical events and his ability to weave together philosophical insights with historical analysis.
Political Theory and Social Commentary: Throughout his life, Russell actively engaged in political debates and social commentary, advocating for progressive causes such as pacifism, nuclear disarmament, and social justice. He wrote numerous books and articles on political theory, including Principles of Social Reconstruction (1916), Roads to Freedom (1918), and Power: A New Social Analysis (1938) (). These works reflect his commitment to democratic principles, individual liberty, and a more just and equitable society. As discussed in our conversation, his parents, Lord and Lady Amberley, also held radical political views for their time, advocating for women’s suffrage, birth control, and democratic reforms, which likely influenced Russell’s own political engagement ().
Science and its Impact on Society: Russell recognized the transformative power of science, both in advancing human knowledge and shaping social structures. He explored the philosophical implications of scientific discoveries, particularly in physics and mathematics, and examined the complex relationship between science, values, and human progress. He wrote extensively on these themes, as seen in The ABC of Relativity (1925), The Scientific Outlook (1931), and The Impact of Science on Society (1951) ().
Education and its Role in Shaping Individuals and Society: Deeply invested in the power of education, Russell believed it played a crucial role in shaping individuals and fostering a more just and humane society. He co-founded an experimental school with his second wife, Dora Russell, and wrote on various aspects of education, advocating for a progressive approach that emphasized critical thinking, creativity, and emotional intelligence. His books on education include On Education Especially in Early Childhood (1926) and Education and the Social Order (1932) ().
Literature and the Art of Writing: Russell’s prowess as a writer extended beyond philosophical treatises. He authored essays and short stories, demonstrating a mastery of language and a talent for crafting compelling narratives. His essay “A Free Man’s Worship” (1903), while later disavowed by him, is considered a literary masterpiece for its eloquent exploration of humanism in a godless universe (). He also published collections of short stories, including Satan in the Suburbs and Other Stories (1953) and Nightmares of Eminent Persons and Other Stories (1954) (). His essay “How I Write” () offers insights into his approach to writing, revealing a meticulous process that emphasized clarity, precision, and the avoidance of stylistic imitation.
Language and its Relationship to Thought and Reality: Intrigued by the complexities of language, Russell explored its role in shaping thought, communicating meaning, and representing the world. He made significant contributions to the philosophy of language, analyzing the structure of language, the nature of meaning, and the relationship between language and logic. His work in this area is reflected in essays such as “Language” (), “Sentences, Syntax, and Parts of Speech” (), and “The Uses of Language” ().
The sources consistently emphasize the breadth and depth of Russell’s intellectual endeavors. While best known for his groundbreaking work in philosophy, his contributions extend far beyond the confines of this discipline, illuminating his commitment to applying reason and critical analysis to a wide range of human concerns and demonstrating his enduring relevance as a public intellectual who grappled with the defining issues of his time.
18-A Nuanced Understanding: It Wasn’t a Single Event
The sources and our conversation history don’t point to a specific historical event that led Bertrand Russell to question traditional beliefs. Instead, they suggest that his skepticism emerged from a combination of factors, including his upbringing, education, and exposure to the ideas of influential thinkers like John Stuart Mill.
Early Exposure to Diverse Religious Beliefs: As discussed in our conversation, Russell’s early religious education exposed him to various theological perspectives, including the Church of England, Presbyterianism, and Unitarianism (). This diverse religious landscape may have prompted him to critically evaluate different doctrines and question the validity of any single religious system.
Emphasis on Individual Conscience: His upbringing emphasized moral austerity and the importance of individual conscience (), encouraging him to rely on his own judgment rather than blindly accepting traditional beliefs.
Intellectual Awakening Through Mill: The sources highlight the profound impact of John Stuart Mill’s writings on Russell’s intellectual development, particularly Mill’s Autobiography (). Reading Mill’s account of his own religious doubts and his rejection of the First-Cause argument for God’s existence played a pivotal role in Russell’s abandonment of traditional religious beliefs (, ).
No Mention of a Specific Event: The sources, which include autobiographical writings by Russell (, , , , ) and biographical overviews of his life and work (, , , , , ), do not attribute his questioning of traditional beliefs to a particular historical event.
Internal Conflict and Pursuit of Reason: Russell describes an internal conflict between his intellectual curiosity, particularly his interest in mathematics, and the perceived constraints of his religious upbringing (). This suggests that his pursuit of reason and his burgeoning interest in philosophy led him to challenge the foundations of his religious beliefs.
It is important to remember that while historical events can shape an individual’s worldview, personal experiences, intellectual development, and exposure to new ideas can also play a significant role in the formation of one’s beliefs. In Russell’s case, it appears that his journey towards skepticism was a gradual process influenced by a complex interplay of personal and intellectual factors rather than a single defining historical event.
19-The Impact of Russell’s Early Religious Upbringing: A Foundation for Skepticism and a Search for Meaning
Bertrand Russell’s early religious education, characterized by a mixture of conflicting doctrines and an emphasis on individual conscience, played a significant role in shaping his philosophical outlook and lifelong engagement with religious questions. The sources reveal that this unconventional upbringing instilled in him a sense of intellectual independence and a critical approach to received wisdom, ultimately leading him to reject traditional religious beliefs while maintaining a deep concern for ethical and spiritual questions.
Here’s a closer look at the key aspects of his religious education and its influence:
Exposure to Diverse Theological Perspectives: Russell was raised in a household where his grandparents, who were responsible for his education, held contrasting religious views [1]. He was exposed to the doctrines of the Church of England, Presbyterianism, and Unitarianism, creating a complex religious landscape that fostered critical thinking and a comparative approach to religious ideas [1]. This early exposure to diverse theological perspectives may have instilled in him a sense of the relativity and contestability of religious doctrines, paving the way for his later skepticism.
Emphasis on Individual Conscience and Moral Austerity: Despite the diverse religious influences, Russell’s upbringing was characterized by a strong emphasis on moral austerity and the importance of individual conscience as the ultimate guide in ethical dilemmas [1]. This emphasis on personal responsibility and independent moral judgment likely contributed to his willingness to question traditional beliefs and to develop his own ethical framework based on reason and compassion, as seen in his later work on ethics.
Early Rejection of Traditional Religious Dogmas: Influenced by the writings of John Stuart Mill, Russell began to question and ultimately reject core religious doctrines, including free will, immortality, and the existence of God, during his adolescence [1, 2]. His rejection of the First-Cause argument for God’s existence, after reading Mill’s Autobiography, is a pivotal moment in his intellectual development, highlighting the role of philosophical reasoning in challenging his early religious beliefs [2, 3]. Notably, Russell’s path mirrors that of his father, who also underwent a similar process of religious questioning and arrived at similar conclusions [4].
Conflict Between Intellectual Curiosity and Theological Dogma: Russell recounts experiencing an internal conflict between his intellectual curiosity, particularly his interest in mathematics, and the perceived ethical constraints of his religious upbringing [5]. This tension between his intellectual pursuits and the perceived limits of religious dogma may have further fueled his skepticism and his desire for a worldview that embraced both reason and human values.
The Search for a Non-Supernatural Source of Meaning and Purpose: Despite rejecting traditional religious beliefs, Russell’s early engagement with religious questions left a lasting impact on his philosophical outlook. He maintained a deep concern for ethical and spiritual issues, seeking to find meaning and purpose in a world without supernatural intervention. This search for meaning is evident in his humanist approach to ethics, his emphasis on the importance of love and compassion, and his exploration of the potential for human progress through reason and scientific understanding. His essay “A Free Man’s Worship” (1903), while later disavowed by Russell, reflects this early grappling with the search for meaning in a universe devoid of traditional religious comforts [6].
While the sources don’t explicitly state that Russell’s rejection of traditional religion caused him personal anguish, he does mention that his family disapproved of his interest in philosophy, suggesting that his intellectual pursuits may have led to some friction or tension within his family [5].
In conclusion, Bertrand Russell’s early religious education, rather than leading him to a firm religious faith, laid the groundwork for his skepticism, his commitment to reason and evidence, and his persistent exploration of ethical and existential questions. His exposure to diverse religious views, the emphasis on individual conscience, and the conflict between his intellectual curiosity and religious dogma all played a part in shaping his lifelong engagement with the complexities of belief, morality, and the human condition.
20-The Political Views of Bertrand Russell’s Parents: Embracing Radical Liberalism
Bertrand Russell’s parents, Lord and Lady Amberley, held radical political views that were considered shocking during the Victorian era ([1-3]). They were deeply influenced by the philosophy of Utilitarianism and the writings of John Stuart Mill, advocating for progressive causes such as women’s suffrage, birth control, and democratic reforms ([3]).
Here are some key points about their political leanings:
Advocates for Women’s Equality: Lady Amberley actively campaigned for women’s rights, challenging the traditional norms that confined women to the domestic sphere. She refused to use the phrase “women’s rights” because, as a Utilitarian, she rejected the concept of natural rights, arguing instead for the equal consideration of women’s interests and well-being ([4]).
Supporters of Birth Control: Lord Amberley’s public support for birth control, a highly controversial topic at the time, sparked a campaign of slander and ultimately led to his defeat in a parliamentary election ([3]). This stance reflects their commitment to individual autonomy and reproductive freedom, defying the prevailing religious and societal norms that condemned such practices.
Champions of Democratic Reforms: Lord Amberley inherited the “aristocratic liberalism” characteristic of the Russell family, which advocated for constitutional liberty and democratic principles ([5]). While willing to tolerate a monarch, they believed the monarch should serve as an “employee of the people” subject to dismissal if they failed to uphold the interests of the citizenry ([5]). This perspective reflects their belief in the sovereignty of the people and the accountability of those in power.
Critics of Traditional Religion and Authority: Lord and Lady Amberley were known for their unconventional religious beliefs, which contributed to their “shocking” reputation in Victorian society ([1]). Lord Amberley refused to attend church on Christmas Day at the age of 21 and became a devoted follower of John Stuart Mill ([3]). This suggests a rejection of traditional religious dogma and a commitment to reason and individual conscience in matters of faith. Their progressive views and willingness to challenge societal norms on issues like birth control and women’s rights further demonstrate their critical stance towards established authority.
Opponents of Imperialism: While Bertrand Russell initially embraced imperialist views influenced by Sidney Webb, he later abandoned this position and became a staunch critic of imperialism ([6]). It is worth noting that this shift in his views may have been influenced by his parents’ political leanings. Though the sources don’t explicitly state their stance on imperialism, their commitment to democratic principles and individual liberty suggests they might have held critical views towards the exploitation and subjugation inherent in colonial practices.
The sources highlight the profound influence of John Stuart Mill on the Amberleys’ political thought ([3, 7]). Mill’s ideas on individual liberty, representative government, and social justice resonated with their own progressive values, shaping their advocacy for a more just and equitable society.
It’s important to acknowledge that the sources focus primarily on Bertrand Russell’s life and philosophical development. Therefore, the information regarding his parents’ political views is relatively limited. However, the available evidence suggests that Lord and Lady Amberley were ardent proponents of social reform and individual liberty, challenging the conservative norms of their time and paving the way for the progressive movements that would gain momentum in the following century.
21-Russell’s View on the Relationship Between Philosophy and Science in the 20th Century: A Shift in Roles
Bertrand Russell sees the 20th century as a period of significant transition in the relationship between philosophy and science. While in previous centuries, philosophy often took the lead in shaping our understanding of the world, he argues that the 20th century witnessed a reversal of roles, with science now driving philosophical inquiry. This shift is driven by the rapid advancements in scientific knowledge, particularly in fields like physics, psychology, and biology, which have challenged traditional philosophical assumptions and opened up new avenues for exploration.
Here’s a breakdown of Russell’s key points regarding this evolving relationship, drawing from the provided sources and our conversation history:
Science as a Source of New Philosophical Problems: Russell argues that scientific discoveries, such as Einstein’s theory of relativity, have profoundly altered our understanding of fundamental concepts like space, time, and matter ( [1] ). These shifts have forced philosophers to re-examine long-held metaphysical views and to grapple with new questions about the nature of reality. For example, the realization that physical objects are not the permanent, solid entities we once thought them to be has prompted philosophical discussions about the nature of perception, the persistence of identity, and the relationship between mind and matter ( [2] ).
The Decline of Traditional Metaphysics: Russell observes a decline in the influence of traditional metaphysical systems, such as those of Kant and Hegel, which attempted to deduce the nature of the world from the nature of knowledge ( [3] ). He attributes this decline to the increasing realization that knowledge does not necessarily modify what is known, and that there is no reason to assume a privileged position for human knowledge in understanding the universe ( [3] ). This leads him to advocate for a more humble and piecemeal approach to philosophy, focusing on clarifying the fundamental ideas of science and synthesizing scientific knowledge into a coherent worldview ( [4] ).
The Rise of Logical Analysis: Russell champions the emergence of a new philosophical approach in the 20th century that he terms “the philosophy of logical analysis” ( [5] ). This approach emphasizes the importance of careful language analysis, logical rigor, and a reliance on empirical evidence in philosophical inquiry ( [6] ). He argues that this method can help resolve long-standing philosophical puzzles by breaking down complex concepts into their simpler components and examining the logical relations between them ( [6] ). In essence, he sees logical analysis as a tool that can be used to sharpen philosophical thinking and to ground it in a more scientific and objective framework.
The Importance of a Scientific Outlook in Ethics and Politics: Russell emphasizes the need to apply a scientific outlook, characterized by a respect for evidence and a willingness to challenge dogma, to social and political issues ( [7] ). He argues that by using scientific methods to understand human behavior and social dynamics, we can develop more effective solutions to problems like poverty, war, and injustice ( ). This underscores his belief that science can and should inform not only our understanding of the natural world but also our ethical and political decisions.
The Interdependence of Science and Philosophy: Despite advocating for a more science-driven approach to philosophy, Russell does not see the two disciplines as entirely separate. He recognizes that philosophy can still play a valuable role in reflecting on the broader implications of scientific discoveries, examining the ethical dilemmas posed by scientific progress, and developing a comprehensive worldview that integrates scientific knowledge with human values and aspirations ( [7] ). He also acknowledges that science itself relies on certain philosophical assumptions, such as the belief in a law-governed universe, which cannot be proven scientifically but are nevertheless essential for the scientific enterprise ( [8] ).
In conclusion, Russell sees the relationship between philosophy and science in the 20th century as one of dynamic interaction, with science increasingly setting the agenda for philosophical inquiry. However, he believes that philosophy can still make valuable contributions by critically examining the foundations and implications of scientific knowledge, and by helping us navigate the ethical and social challenges posed by scientific progress. He advocates for a more humble, analytical, and evidence-based approach to philosophical inquiry, grounded in the insights of science but not limited to a purely scientific perspective.
22-A Wise Use of Scientific Technique: Creating a Society of Opportunity and Security
Bertrand Russell strongly believes that a wise application of scientific technique is essential for building a society that offers both opportunity and security for all. This belief stems from his conviction that science, when properly utilized, can provide the means to overcome the limitations of human nature, mitigate the negative consequences of industrialization, and address the root causes of poverty, war, and social injustice.
The sources present several arguments supporting Russell’s view:
Science as a Tool for Understanding and Shaping Human Behavior: Russell argues that science, particularly psychology, can help us understand the underlying causes of human behavior, including both our positive and negative tendencies ( ). By applying scientific methods to the study of human nature, we can identify the environmental factors that promote desirable emotions and those that lead to destructive passions ( ). This understanding can then be used to shape education and social policies in ways that foster individual development and promote a more harmonious society.
Science as a Means to Enhance Human Well-being: Russell sees science as having immense potential to improve human health, extend lifespan, and alleviate suffering ( ). He cites examples like the development of vaccines and other medical advances that have significantly reduced the incidence of disease and increased life expectancy ( ). He believes that with further scientific progress, we can continue to make strides in combating illness, improving nutrition, and creating a healthier and more comfortable life for all.
Science as a Source of Economic Progress: Russell recognizes that scientific advancements, particularly in fields like agriculture and industry, have led to significant increases in productivity and economic growth ( ). He argues that by harnessing the power of science and technology, we can create a world where poverty is eradicated and everyone has access to the basic necessities of life ( ).
Science as a Foundation for a Rational and Just Society: Russell believes that a scientific outlook on the world, characterized by a respect for evidence, a willingness to challenge dogma, and a commitment to reason-based decision-making, is essential for creating a more just and equitable society ( ). He argues that by applying scientific methods to social and political problems, we can develop more effective solutions based on objective analysis rather than prejudice or ideology.
Science as a Path to Global Cooperation and Peace: Russell is acutely aware of the destructive potential of scientific advancements, particularly in the development of weapons of mass destruction ( ). However, he also believes that science can be a powerful force for peace if it is used to promote international cooperation and understanding ( ). He argues that by focusing on the shared interests of humanity, such as the prevention of war and the preservation of the environment, science can help bridge ideological divides and foster a sense of global solidarity ( ). He calls on scientists to play a leading role in educating the public about the dangers of war and to advocate for policies that promote peace and disarmament ( ).
Overcoming the Limits of Human Nature: Russell argues that many of the social and political problems we face stem from the limitations of human nature. Our tendency towards greed, fear, and aggression can lead to conflict, exploitation, and the pursuit of power at the expense of others ( ). However, he believes that by using scientific techniques wisely, we can create a world where these negative impulses are mitigated, where cooperation and mutual respect prevail, and where human potential can flourish.
Note: It’s worth noting that while Russell champions the potential of science to improve human life, he is also acutely aware of its potential for misuse. He cautions against allowing technology to become an instrument of oppression or to exacerbate existing social inequalities ( ). He emphasizes the importance of ethical considerations in the development and application of scientific knowledge, arguing that scientific progress must be guided by humanistic values and a concern for the well-being of all ( ). He stresses that a solely scientific approach to problems is insufficient, and ethical considerations are essential for responsible scientific progress. He advocates for a balance between scientific advancement and ethical responsibility, emphasizing that technology should serve human needs and promote human flourishing rather than becoming a force for destruction or control.
23-Reconciling Individual Desires and Social Needs: The Core Tension in Ethics and Politics
According to Bertrand Russell, the fundamental problem of ethics and politics lies in finding ways to reconcile the needs of social life with the urgency of individual desires [1]. This challenge has persisted throughout history, leading to various attempts to strike a balance between individual freedom and the requirements of social order.
The sources explore several aspects of this fundamental problem, highlighting the tensions between individual autonomy and social cohesion:
The Role of Law and Religion in Enforcing Social Order: Russell notes that societies have historically relied on laws and religious doctrines to regulate individual behavior and maintain social cohesion [1]. Criminal law, backed by the coercive power of the state, deters individuals from engaging in antisocial actions. Religion, especially when it teaches that disobedience to authority is a sin, provides an additional layer of moral reinforcement. However, Russell expresses skepticism towards relying solely on external authority to enforce morality. He argues that true morality should stem from internal convictions and a genuine concern for the well-being of others [2], not merely from fear of punishment or social disapproval.
The Limits of State Power: While acknowledging the need for some degree of social control, Russell cautions against the dangers of excessive state power. He argues that an overly powerful state can suppress individual freedom, stifle creativity, and impede progress. He emphasizes the importance of safeguarding individual liberties and ensuring that the state’s authority is used responsibly and with due respect for human rights [1].
The Importance of Education: Russell sees education as playing a crucial role in shaping individuals who are both self-reliant and socially responsible. He argues that education should foster critical thinking, encourage empathy and compassion, and cultivate a sense of justice and fairness [1, 3, 4]. By equipping individuals with the intellectual and moral tools to navigate the complexities of social life, education can contribute to a more harmonious and just society.
The Dangers of Dogmatism: Russell warns against the dangers of dogmatic ideologies, both religious and political, arguing that they can lead to intolerance, conflict, and a suppression of individual thought and expression. He advocates for an open and tolerant society that encourages free inquiry, welcomes diverse perspectives, and values reason and evidence over blind faith or unquestioning obedience to authority [5].
Balancing Individuality and Citizenship: In our previous conversation, we discussed Russell’s analysis of different types of liberalism. His identification of rational and romantic liberalism suggests that finding the right balance between individual desires and social needs requires careful consideration of both individual rights and the common good. Navigating this tension is an ongoing challenge for any society seeking to promote both individual flourishing and social harmony.
In essence, Russell’s view of the fundamental problem of ethics and politics emphasizes the need to create a society that allows for individual development and self-realization while ensuring social stability and cooperation. He believes that this can be achieved through a combination of enlightened self-interest, a commitment to reason and evidence-based decision-making, and a cultivation of moral virtues such as compassion, tolerance, and a sense of justice.
24-The Two Types of Liberalism: Bentham and Rousseau
Bertrand Russell identifies two key types of liberalism that have shaped political thought and practice: rational liberalism, represented by Jeremy Bentham, and romantic liberalism, exemplified by Jean-Jacques Rousseau. He argues that these two strands of liberalism have historically been in a dynamic relationship of “alternate alliance and conflict” (). The sources, however, do not provide a detailed explanation of these two types of liberalism or their specific characteristics.
To understand Russell’s distinction, it is helpful to draw on some background knowledge of these two influential thinkers and their contrasting approaches to political philosophy.
Note: The following information about Bentham and Rousseau is not directly from the provided sources and you may wish to verify it independently.
Jeremy Bentham (1748-1832): Bentham was a British philosopher and social reformer known for his utilitarian philosophy. Utilitarianism emphasizes the greatest happiness principle, which holds that actions are right in proportion to their tendency to promote happiness and wrong in proportion to their tendency to produce the reverse of happiness. Bentham applied this principle to political and legal systems, advocating for reforms that would maximize social welfare and minimize suffering. He believed in a scientific approach to government, emphasizing efficiency, rationality, and the impartial application of laws. Bentham’s focus on individual happiness and rational social organization aligns with Russell’s characterization of him as a representative of rational liberalism.
Jean-Jacques Rousseau (1712-1778): Rousseau was a Genevan philosopher whose writings had a profound influence on the Enlightenment and the French Revolution. He is known for his concept of the social contract, which posits that individuals voluntarily surrender some of their natural rights in exchange for the protection and benefits of living in a society. However, Rousseau differed from other social contract theorists like John Locke in his emphasis on the general will, a concept that represents the collective good of the community as a whole. He believed that individuals should subordinate their own interests to the general will, which he saw as a higher moral authority. Rousseau’s emphasis on the collective good, the importance of emotion and sentiment in human affairs, and his critique of the corrupting influence of civilization align with Russell’s description of him as a representative of romantic liberalism.
By highlighting the contrast between Bentham and Rousseau, Russell suggests that liberalism encompasses a spectrum of views, ranging from those that prioritize individual rights and rational social organization to those that emphasize the collective good and the role of emotion and sentiment in shaping political life. The historical interplay between these two strands of liberalism has contributed to the evolution of liberal thought and the diverse forms it takes in different contexts.
25-Education for Global Citizenship: Bertrand Russell’s Vision
Bertrand Russell viewed education as playing a crucial role in fostering international understanding and promoting a more peaceful and cooperative world order. He believed that education could help to overcome the narrow nationalism, prejudices, and fear that often lead to conflict. The sources offer a detailed examination of his educational philosophy, highlighting the specific ways in which he believed education could contribute to a more harmonious world.
Cultivating a Global Perspective: Russell stresses the importance of education in broadening students’ horizons, helping them to see their own country and culture as part of a larger, interconnected world. He argues that schools should teach world history from an impartial standpoint, presenting different perspectives and challenging nationalistic biases ([1-3]). This aligns with his belief that a sense of history is essential to understanding the present and envisioning a better future ([1, 4, 5]). He argues that education should foster an awareness of “the modern interdependence of different groups of men, and the importance of cooperation and the folly of conflict” ([3]). By understanding the interconnectedness of the world, students can develop a sense of global citizenship and a commitment to working for the common good.
Promoting Open-mindedness and Critical Thinking: Russell emphasizes the importance of education in promoting open-mindedness and critical thinking skills ([6-8]). He advocates for a scientific approach to learning, encouraging students to question assumptions, examine evidence, and form their own judgments ([6, 7, 9]). This aligns with his broader philosophical commitment to reason and his belief that dogmatism and blind faith are major sources of conflict ([8]). He argues that education should help students to “make beliefs tentative and responsive to evidence,” rather than indoctrinating them with fixed ideologies ([8]). He sees this intellectual independence as crucial to resisting the manipulation of propagandists and forming informed opinions on complex issues ([8]).
Challenging Prejudice and Fostering Tolerance: Russell sees education as a vital tool for combating prejudice and fostering tolerance ([8, 10]). He argues that education should expose students to different cultures, perspectives, and ways of life, helping them to understand and appreciate diversity ([10, 11]). This, he believes, can help to break down stereotypes and reduce the fear and hatred of the unfamiliar that often lead to conflict ([12]). He emphasizes the importance of teaching respect for individual liberty and the rights of others, even those with different beliefs or backgrounds ([8, 13, 14]). This aligns with his broader philosophical commitment to individual freedom and his belief in the importance of mutual forbearance in a pluralistic society ([8]).
Encouraging Emotional Intelligence and Compassion: Russell argues that education should not focus solely on intellectual development but should also cultivate emotional intelligence and compassion ([15-17]). He emphasizes the importance of teaching students to understand and manage their own emotions, as well as to empathize with the feelings and perspectives of others ([16, 17]). He believes that this can help to reduce aggression and promote peaceful conflict resolution ([17]). This aligns with his view that a good life is characterized by love guided by knowledge ([15]). He sees education as playing a vital role in nurturing these qualities, helping students to become not only intelligent but also kind, compassionate, and capable of building harmonious relationships with others.
The Teacher as a Role Model: Russell places great emphasis on the role of the teacher in fostering international understanding ([11, 18-20]). He believes that teachers should not only impart knowledge but should also serve as role models of open-mindedness, critical thinking, and compassion ([11, 18-20]). He argues that teachers should embody the values they seek to instill in their students, demonstrating a genuine interest in learning, a respect for diversity, and a commitment to truth and justice ([11, 19]). He criticizes educational systems that prioritize obedience and conformity over intellectual curiosity and individual development ([8, 20, 21]).
In essence, Bertrand Russell envisions education as a powerful force for shaping a more peaceful and just world. He believes that by cultivating a global perspective, promoting critical thinking and open-mindedness, challenging prejudice, fostering tolerance, and nurturing emotional intelligence and compassion, education can help to break down the barriers that divide humanity and create a world where cooperation and understanding prevail over conflict and division.

27-The Inevitability of War Without World Government: Bertrand Russell’s Reasoning
Bertrand Russell contends that without the establishment of a world government, large-scale wars are virtually unavoidable. This view stems from his analysis of the inherent limitations of the nation-state system, particularly in the context of rapidly advancing technology and the emergence of weapons capable of planetary destruction. The sources provide a comprehensive articulation of his arguments, exploring the interplay of political, economic, and psychological factors that he believed make war an almost inevitable outcome of the existing world order.
Here’s a closer look at his key arguments:
The Anarchic Nature of the International System: Russell consistently emphasizes the inherent anarchy of the international system, where there is no higher authority to enforce agreements, resolve disputes, or prevent aggression between sovereign states. He argues that in such a system, nations are ultimately reliant on their own military power for security, leading to a perpetual arms race and a climate of fear and distrust. This, he contends, creates a situation where even small conflicts can escalate into major wars, as each nation acts to protect its own interests and prevent others from gaining a strategic advantage. He compares the situation to a group of individuals living in a state of nature, where the absence of law and a central authority leads to constant conflict and insecurity [1].
The Rise of Destructive Technology: Russell’s arguments gain particular urgency in the context of the 20th century, marked by the rapid development of increasingly destructive weapons. He argues that the invention of nuclear weapons has fundamentally altered the nature of warfare, making large-scale conflicts potentially catastrophic for the entire human race. He points out that in the past, wars, while destructive, were often limited in scope and rarely threatened the survival of civilization itself [2]. However, with the advent of nuclear weapons, this is no longer the case. A single nuclear exchange, he argues, could lead to the deaths of hundreds of millions and potentially trigger a global environmental catastrophe that would render the planet uninhabitable [3]. In such a scenario, the traditional notion of ‘victory’ becomes meaningless, as both victor and vanquished would suffer unimaginable devastation.
The Persistence of Nationalism and Power Politics: Russell identifies the persistence of nationalism and power politics as another major obstacle to lasting peace. He argues that nations are often driven by narrow self-interest, seeking to expand their power, influence, and resources at the expense of others. This, he suggests, leads to a constant struggle for dominance, with nations forming alliances, vying for control of strategic territories, and engaging in economic and political maneuvering to advance their own interests. This pursuit of national self-interest, he argues, makes cooperation and compromise difficult, and creates a fertile ground for conflict [4]. He suggests that in a world where national loyalties remain strong and international institutions are weak, the temptation to resort to force to achieve national objectives will remain powerful [5].
The Interplay of Fear and Aggression: Russell also analyzes the psychological dimensions of war, emphasizing the interplay of fear and aggression in fueling conflict. He argues that fear of attack, whether real or perceived, often leads to preemptive aggression, as nations seek to eliminate potential threats and secure their own safety. This, he suggests, creates a vicious cycle, with each nation’s defensive measures perceived as a threat by others, leading to further escalation and an ever-increasing likelihood of war. He sees this dynamic as particularly dangerous in the nuclear age, where fear of a surprise attack could trigger a catastrophic preemptive strike [6].
The Limitations of Existing International Institutions: While acknowledging the efforts of organizations like the League of Nations and the United Nations, Russell argues that these institutions are inherently inadequate to prevent war in the long run. He points out that they lack the power to enforce their decisions, are often paralyzed by the veto power of powerful states, and are ultimately reliant on the goodwill of their member nations, which often proves unreliable. He suggests that without a genuine transfer of sovereignty from national governments to a world authority, international institutions will remain toothless and unable to prevent the outbreak of major wars [7].
In essence, Bertrand Russell argues that the nation-state system, characterized by anarchy, intense competition, and the absence of a higher authority, creates a situation where war is not merely a possibility but a virtual inevitability. He believes that this system is particularly dangerous in the context of modern technology, where the destructive power of weapons has reached a point where a single conflict could spell the end of civilization. His analysis offers a stark warning about the perils of clinging to outdated notions of sovereignty and the urgent need for a fundamental rethinking of global governance if humanity is to survive the challenges of the 21st century.
28-Weighing the Scales: Arguments for and Against World Government
The sources offer a nuanced examination of the potential benefits and pitfalls of a world government, reflecting Bertrand Russell’s deep engagement with political philosophy and his concerns about the unprecedented challenges facing humanity in the 20th century. Here’s a breakdown of the main arguments presented:
Arguments in Favor of World Government:
The Imperative of Preventing War: The sources consistently present the prevention of war, especially in the nuclear age, as the most compelling argument for a world government [1-5]. Russell argues that the advent of nuclear weapons has rendered traditional notions of national sovereignty and military defense obsolete, as a major war would likely result in the annihilation of both victor and vanquished, along with neutral nations [4, 6, 7]. He believed that only a single world authority, possessing a monopoly on the most destructive weapons, could effectively prevent such a catastrophe [1, 6, 8]. This reflects his view that traditional power politics become self-defeating in the context of nuclear weapons, necessitating a fundamental shift in global governance to ensure human survival.
Promoting Economic Justice and Cooperation: Russell argues that a world government could facilitate greater economic justice and cooperation, mitigating the conflicts that arise from economic disparities and competition between nations [9, 10]. He points to the problems caused by economic nationalism, trade barriers, and the unequal distribution of resources, arguing that a world authority could manage these issues more effectively, promoting global prosperity and reducing the resentment that breeds conflict [9, 10]. This aligns with his socialist leanings and his belief that economic inequalities are a major source of conflict and instability, requiring internationalist solutions to address global poverty and resource scarcity.
Addressing Global Challenges: Russell emphasizes the interconnectedness of the world and the need for global solutions to address challenges that transcend national boundaries, such as climate change, pandemics, and poverty [11]. He suggests that a world government would be better equipped to handle such issues, facilitating coordinated action and resource allocation to address common problems effectively [11]. This reflects his belief that many of the most pressing challenges facing humanity require collective action on a global scale, transcending the limitations of national governments and their often competing interests.
Arguments Against World Government:
The Risk of Tyranny: A prominent concern raised by Russell is the potential for a world government to become tyrannical, suppressing individual liberties and imposing a single, potentially oppressive ideology on the entire planet [12-14]. He acknowledges this danger, particularly if the world government were to emerge from conquest or be controlled by an unaccountable elite [14, 15]. He stresses the importance of safeguards, such as a democratic constitution and the protection of individual rights, to prevent the concentration of power and ensure that a world government serves the interests of humanity rather than becoming a tool for oppression [14, 15]. This reflects his broader philosophical commitment to individual liberty and his skepticism of concentrated power, regardless of its ideological justification.
The Challenge of Cultural Diversity: Russell recognizes the immense cultural diversity of the world and the potential difficulties in creating a world government that respects this diversity while maintaining unity and coherence [11, 16]. He acknowledges the dangers of imposing a single cultural model or suppressing minority cultures, arguing that a successful world government would need to embrace pluralism and find ways to accommodate the diverse values and traditions of its constituent peoples [11, 16]. This aligns with his belief in the value of cultural diversity and his wariness of any system that seeks to enforce uniformity, whether in matters of belief, culture, or political organization.
Practical Obstacles to Implementation: Russell also highlights the practical challenges of establishing a world government, given the existing power structures, national rivalries, and ideological conflicts [17-19]. He questions whether nations would willingly surrender sovereignty and whether a world government could effectively enforce its authority in the face of resistance from powerful states or groups [17, 18]. He suggests that a gradual approach, perhaps starting with regional federations or increased cooperation on specific issues, might be more realistic than attempting to create a full-fledged world government in the near future [20]. This reflects his pragmatic side, acknowledging the real-world obstacles to implementing idealistic visions and emphasizing the need for incremental progress towards a more peaceful and cooperative world order.
Russell’s Conclusion: A Cautious Hope
While acknowledging the potential pitfalls, Russell ultimately believed that the imperative of preventing a nuclear war outweighed the risks associated with a world government. He argued that the unprecedented destructive power of modern weapons necessitated a fundamental rethinking of traditional political structures, and that a world government, if properly constituted, offered the best hope for ensuring human survival and fostering a more just and peaceful world [21-23]. He recognized that achieving this goal would require not only political and economic changes but also a shift in human consciousness, a willingness to embrace a global perspective, and a commitment to overcoming the fear and hatred that fuel conflict [16, 23, 24]. His vision offers a challenging but ultimately hopeful perspective on the future of humanity, suggesting that our collective survival hinges on our ability to transcend national divisions, embrace cooperation, and create a world order that prioritizes peace and human well-being over the pursuit of power and dominance.
29-Education as a Cornerstone of Democracy: Bertrand Russell’s Perspective
Bertrand Russell viewed education as playing a critical role in the success and flourishing of a democracy. He believed that education could either bolster or undermine democratic ideals depending on its aims and methods. The sources highlight his belief that education in a democracy should cultivate informed, critical, and compassionate citizens capable of participating effectively in self-governance and contributing to a just and harmonious society.
Here’s a closer look at his perspective:
Countering Dogmatism and Promoting Independent Thought: Russell emphasizes the danger of dogmatism in a democracy, arguing that uncritical acceptance of authority can lead to the suppression of dissent and hinder progress. He warns against the use of education as a tool for indoctrinating citizens with a particular ideology or set of beliefs, as seen in totalitarian regimes. Instead, he advocates for educational systems that promote independent thought, critical thinking, and a willingness to challenge received wisdom. In [1], he states, “It is the executive type that encourages uniformity, while the other type will rejoice in ability (which is in itself an eccentricity), and for the sake of ability will readily tolerate other forms of oddity.” He believed that citizens in a democracy should be equipped to evaluate information, form their own judgments, and engage in reasoned debate, rather than blindly following leaders or succumbing to propaganda [2, 3]. This aligns with his broader philosophical stance, which emphasizes the importance of reason, evidence-based inquiry, and the pursuit of truth through critical examination [4].
Cultivating a Global Perspective: Russell recognized the increasing interconnectedness of the world and argued that education in a democracy should foster a global perspective. He believed that schools should move beyond narrow, nationalistic narratives and teach world history from an impartial standpoint, emphasizing shared humanity and the importance of international cooperation [5]. He envisioned educational systems that would cultivate citizens who are not only knowledgeable about their own nation’s history and values but who are also aware of global issues, respectful of other cultures, and capable of engaging constructively with people from diverse backgrounds. This reflects his belief that democracy thrives in an environment of mutual understanding and respect, where citizens can appreciate diverse perspectives and work collaboratively to address common challenges [6].
Education for Responsible Citizenship: Russell believed that education should prepare citizens for active and responsible participation in a democracy. This includes not only imparting knowledge and critical thinking skills but also cultivating the emotional and moral qualities essential for a functioning democratic society. He argues that education should foster compassion, empathy, and a sense of justice, enabling citizens to engage in political discourse with civility, consider the needs of others, and work towards a more equitable and harmonious society. This emphasis on character development aligns with his broader ethical framework, which prioritizes human happiness and well-being, grounded in love guided by knowledge [7].
Safeguarding Education from Undue Influence: Russell expressed concern about the potential for undue influence on education, particularly from those in power. He believed that education should be protected from manipulation by political or economic interests, arguing that such manipulation undermines its core purpose of fostering independent thought and preparing citizens for active participation in a democracy [8]. He saw the rise of nationalism and the increasing control of education by governments as threats to intellectual freedom and democratic values, advocating for greater autonomy for educators and a curriculum that prioritizes critical thinking and a broad, humanistic perspective. This reflects his broader concerns about the dangers of unchecked power and the importance of safeguarding individual liberties in a democratic society [9].
In summary, Bertrand Russell believed that education plays a vital role in shaping the character and intellectual capacity of citizens, ultimately influencing the health and longevity of a democracy. He advocated for an educational approach that:
Champions critical thinking and independent judgment, equipping citizens to resist dogma and propaganda.
Fosters a global perspective, promoting understanding and cooperation across national boundaries.
Cultivates the emotional and moral qualities essential for responsible citizenship, including compassion, empathy, and a sense of justice.
Safeguards education from undue influence by political or economic interests, preserving its role as a foundation for democratic values.
His insights offer a valuable framework for reflecting on the purpose of education in a democratic society and for ensuring that educational systems empower individuals to participate meaningfully in self-governance and contribute to the creation of a just, compassionate, and intellectually vibrant world.
30-A Vision of Reverence and Growth: Bertrand Russell’s Philosophy of Education
Bertrand Russell’s perspective on education was deeply intertwined with his broader philosophical views, emphasizing critical thinking, individual growth, and the cultivation of values that foster a more humane and just world. His opinions on education, scattered throughout his writings, reveal a passionate advocate for progressive methods, challenging traditional approaches that prioritize obedience and rote learning over intellectual curiosity and emotional well-being.
Here are some of his central opinions on education, as gleaned from the sources:
Reverence for the Individual: Russell believed that education should be guided by a deep reverence for the individual child, recognizing their unique potential and inherent worth. He criticizes the traditional view of the child as “clay” to be molded by the educator, arguing that such an approach stifles natural curiosity and imposes rigid conformity [1]. Instead, he advocates for an approach that fosters individual growth and encourages children to develop their own sense of purpose and direction [1, 2]. This emphasis on respecting individual differences and nurturing innate potential reflects his broader commitment to individual liberty and the importance of allowing each person to flourish in their own unique way.
Cultivating Curiosity and the Joy of Learning: Russell saw curiosity as the foundation of the intellectual life, lamenting the tendency of traditional education to extinguish this natural drive in children [3]. He argues that learning should be a source of joy and discovery, not a tedious chore enforced through punishment [4, 5]. He advocates for educational methods that engage children’s natural curiosity, presenting challenges that are stimulating yet attainable, allowing them to experience the satisfaction of success and develop a love for learning [5, 6]. This emphasis on fostering intrinsic motivation aligns with his broader belief that happiness and fulfillment are essential components of a good life.
The Importance of Emotional Education: In contrast to the traditional emphasis on intellectual development, Russell stressed the equal importance of emotional education [7]. He argued that schools should focus on fostering emotional well-being and cultivating desirable character traits such as courage, kindness, and a sense of justice [2, 8, 9]. He believed that psychology could play a key role in identifying environments that promote positive emotional development, allowing children to navigate the challenges of life with resilience and compassion [7]. This emphasis on emotional intelligence reflects his broader concern for creating a more humane and just world where individuals are equipped to handle conflict constructively and contribute to the well-being of others.
Promoting Critical Thinking and Open Inquiry: A champion of reason and critical thinking, Russell advocated for educational methods that encourage skepticism, independent judgment, and a willingness to challenge received wisdom [10, 11]. He believed that students should be exposed to diverse perspectives, learning to evaluate evidence and form their own conclusions rather than blindly accepting authority or dogma [9, 11]. He suggests using historical examples of flawed arguments to illustrate the dangers of unquestioning acceptance of authority and the importance of critical evaluation [11]. This emphasis on intellectual independence aligns with his broader philosophical commitment to free inquiry and the pursuit of truth through reason and evidence.
Education for Citizenship in a Global World: Recognizing the growing interconnectedness of the world, Russell argued that education should prepare students for responsible citizenship in a global community [12]. He believed that schools should foster an internationalist perspective, teaching world history from an impartial viewpoint and emphasizing the importance of cooperation and understanding across national boundaries [12]. He proposed innovative approaches to ensure impartiality in the teaching of history, suggesting that different sections of textbooks be written by authors from diverse cultural backgrounds [12]. This vision of global citizenship reflects his broader commitment to peace and his belief in the power of education to overcome prejudice and promote international understanding.
The Teacher as a Catalyst for Growth: Russell placed great value on the role of the teacher, arguing that their primary function should be to facilitate intellectual and emotional growth, not to impose conformity or instill dogma [13, 14]. He believed that the best teachers are those who possess a genuine love for their subject and a deep affection for children, creating environments where learning is a source of joy and discovery [14, 15]. He criticized the tendency of educational systems to prioritize administrative tasks over teaching, resulting in a hierarchy that rewards bureaucratic efficiency over genuine passion for education [15]. This emphasis on the importance of inspirational and dedicated teachers reflects his belief that education should be a transformative experience that empowers individuals to live meaningful and fulfilling lives.
In conclusion, Bertrand Russell’s opinions on education offer a compelling vision of learning as a process of individual growth, intellectual exploration, and ethical development. He challenges traditional approaches that prioritize rote learning and obedience, advocating for methods that foster curiosity, critical thinking, and emotional well-being. His emphasis on global citizenship, the importance of dedicated teachers, and the need for a reverence for the individual child provide valuable insights for those seeking to create a more just, compassionate, and intellectually vibrant world.
31-Russell on Religion: A Critical and Evolving Perspective
Bertrand Russell engaged with religious questions throughout his life, consistently expressing a critical and often controversial perspective on organized religion and traditional beliefs. While his views evolved over time, his stance can be characterized as agnostic, emphasizing the limits of human knowledge when it comes to metaphysical claims and advocating for an ethical framework grounded in reason and compassion rather than religious dogma.
Here are some of his key opinions on religion, as evidenced in the sources:
Rejection of Traditional Dogmas: Russell consistently rejected traditional religious dogmas, finding them unsupported by evidence and often harmful in their effects. He recounts his early loss of faith, triggered by reading John Stuart Mill’s argument against the First Cause argument for the existence of God [1]. This skepticism towards religious doctrines persisted throughout his life. In, he explicitly states, “An agnostic thinks it impossible to know the truth in matters such as God and the future life with which Christianity and other religions are concerned” [2]. He criticizes the reliance on scripture and Church teachings as sources of moral authority, arguing that such reliance stifles inquiry and perpetuates harmful superstitions, particularly in the realm of sexual ethics [3].
Critique of the Character of Christ: Russell did not shy away from critiquing the figure of Christ, challenging the widespread view of him as the epitome of moral perfection. He highlights passages in the Gospels where Christ displays anger and threatens eternal damnation, arguing that these instances are inconsistent with a truly compassionate and benevolent nature [4, 5]. He further challenges the notion that Christ was the wisest of men, suggesting that his teachings contain logical inconsistencies and promote fear and guilt rather than genuine ethical guidance.
Emphasis on Reason and Ethics: Despite his rejection of religious dogma, Russell did not dismiss the importance of ethical considerations. He advocated for a secular morality grounded in reason and compassion. In, he argues, “The world has need of a philosophy, or a religion, which will promote life. But in order to promote life it is necessary to value something other than mere life” [6]. This suggests that he saw a need for a system of values that transcends the mere pursuit of survival and embraces a broader vision of human flourishing. He proposed an ethical framework that prioritizes happiness, knowledge, and the pursuit of wider, more impartial perspectives [7].
Concern for the Social Impact of Religion: Russell expressed deep concern about the social and political consequences of organized religion. He argued that religious institutions, in their attempts to defend dogma and maintain power, often resort to suppressing dissent and hindering intellectual progress [8]. He criticizes the historical role of the Church in opposing social and moral advancements, citing its resistance to reforms in criminal law, the treatment of marginalized groups, and the pursuit of peace [9]. This critique suggests a deep skepticism towards the claim that religion is a necessary foundation for a just and compassionate society.
Agnosticism as an Open Stance: While consistently critical of organized religion and traditional beliefs, Russell maintained an agnostic position, acknowledging the possibility of truths beyond human comprehension. In, he explains, “An atheist, like a Christian, holds that we can know whether or not there is a God… The Agnostic suspends judgment, saying that there are not sufficient grounds either for affirmation or for denial” [2]. This suggests that while he found existing evidence for religious claims unconvincing, he remained open to the possibility of future evidence that might shift his perspective.
The Essence of Religion: Interestingly, while deeply critical of dogma, Russell did not entirely dismiss the concept of religion. In, he explores the “essence of religion” as residing in a sense of wonder, reverence, and a desire for unity with something larger than oneself [10]. He suggests that this essence can be experienced independently of specific beliefs, advocating for a form of spirituality that embraces an expansive worldview and a commitment to ethical living without relying on supernatural claims.
In summary, Russell’s opinions on religion were characterized by:
A steadfast rejection of traditional dogmas and reliance on scripture or Church teachings.
A critical examination of the figure of Christ and the ethical implications of his teachings.
An advocacy for a secular morality based on reason, compassion, and a commitment to human flourishing.
A deep concern for the social and political consequences of organized religion, particularly its tendency to stifle dissent and impede progress.
An agnostic stance that acknowledged the limits of human knowledge while remaining open to the possibility of future evidence.
An exploration of the “essence of religion” as a human experience independent of specific beliefs, suggesting that spirituality and a sense of unity with the universe can be cultivated without relying on supernatural claims.
Russell’s views on religion, while often controversial, offer a valuable perspective on the role of faith and reason in human life. He challenges us to engage in critical thinking about religious claims, to seek ethical guidance from sources beyond dogma, and to cultivate a sense of wonder and interconnectedness with the world around us.
32-Language as a Lens and a Tool: Russell’s View on the Interplay Between Language and the World
Bertrand Russell viewed language as a powerful instrument for understanding and interacting with the world, while also recognizing its potential to mislead and distort our perceptions of reality. He emphasized the importance of carefully analyzing language to avoid philosophical pitfalls and gain clearer insights into the structure of the world.
Here are key aspects of Russell’s position on the relationship between language and the world, as revealed in the sources:
Language as a Reflection of the World: Russell believed that the structure of language can provide clues about the structure of the world. In, he states, “I think, a discoverable relation between the structure of sentences and the structure of the occurrences to which the sentences refer. I do not think the structure of non-verbal facts is wholly unknowable, and I believe that, with sufficient caution, the properties of language may help us to understand the structure of the world.” This suggests that he saw language not merely as a tool for communication, but as a reflection of the underlying reality it attempts to represent.
The Limitations and Pitfalls of Language: While acknowledging the value of language as a tool for understanding, Russell also recognized its inherent limitations and the potential for it to create philosophical confusion. In, he cautions, “Language, as appears from the above discussion of Mr Jones, though a useful and even indispensable tool, is a dangerous one, since it begins by suggesting a definiteness, discreteness, and quasi-permanence in objects which physics seems to show that they do not possess.” This highlights his concern that language, with its tendency to categorize and label, can lead to a false sense of certainty and concreteness about the world, obscuring the dynamic and fluid nature of reality as revealed by science.
The Importance of Logical Analysis: To navigate these linguistic pitfalls, Russell emphasized the importance of logical analysis. He believed that by carefully examining the structure and meaning of language, we can identify and dismantle false beliefs and gain a more accurate understanding of the world. This approach is reflected in his work on logical atomism, which sought to break down complex propositions into their simplest, most fundamental components to clarify their meaning and relationship to reality.
Language as a Tool for Thought and Communication: Beyond its role in understanding the world, Russell recognized the crucial role of language in facilitating thought and communication. He argued that “Language serves not only to express thoughts, but to make possible thoughts which could not exist without it.” This highlights the idea that language is not merely a passive tool for expressing pre-existing thoughts, but actively shapes and expands our cognitive abilities, allowing us to formulate and grasp complex ideas that would otherwise remain inaccessible.
The Evolution and Autonomy of Language: Russell acknowledged the evolving nature of language and its capacity to develop independently of the specific objects and concepts it initially represented. In, he observes that “Language, once evolved, acquires a kind of autonomy: we can know, especially in mathematics, that a sentence asserts something true, although what it asserts is too complex to be apprehended even by the best minds.” This suggests that language, while rooted in our experiences of the world, can develop its own internal logic and systems of meaning, capable of expressing truths that extend beyond our immediate comprehension.
In conclusion, Russell’s position on the relationship between language and the world can be characterized as follows:
He saw language as both a reflection of and a tool for understanding reality, acknowledging its potential to reveal insights into the structure of the world.
He recognized the inherent limitations of language and its potential to mislead, urging careful analysis to avoid philosophical confusion.
He emphasized the importance of logical analysis as a means to clarify meaning, dismantle false beliefs, and gain a more accurate understanding of the world.
He acknowledged the dynamic nature of language and its ability to shape and expand our cognitive abilities, facilitating complex thought and communication.
Russell’s insights into the interplay between language and the world offer a valuable framework for navigating the complexities of human understanding and highlight the importance of using language with precision and awareness to illuminate, rather than obscure, our understanding of reality.
33-Knowledge as a Double-Edged Sword: Russell’s Perspective on the Intertwined Nature of Knowledge and Power
Bertrand Russell recognized a deep and complex relationship between knowledge and power, viewing knowledge as a potent force capable of both great good and profound harm. He saw the pursuit of knowledge as often intertwined with the desire for power, highlighting how knowledge can be a means to control and manipulate the world around us. However, he also believed that knowledge, guided by ethical principles and wisdom, could be a powerful tool for improving the human condition.
The sources provide several key insights into Russell’s perspective on this intricate relationship:
Knowledge as an Instrument of Power: Russell acknowledges that knowledge, particularly scientific knowledge, grants humans an increased ability to control and shape their environment. He argues that “The power of using abstractions is the essence of intellect, and with every increase in abstraction the intellectual triumphs of science are enhanced” [1]. This suggests that he sees the ability to think abstractly, a cornerstone of intellectual development and knowledge acquisition, as directly linked to a heightened capacity for intellectual power, a power that extends to manipulating the physical world.
The Allure of Power in Scientific Pursuits: While not suggesting that the pursuit of knowledge is solely driven by a desire for power, Russell recognizes the powerful allure that power holds for some individuals engaged in scientific endeavors. In discussing pragmatism, he points to “love of power” as one of its central appeals [2]. He observes that pragmatism, with its emphasis on the practical application of knowledge to effect change in the world, can be particularly attractive to those driven by a desire for power. This implies that he sees the thirst for knowledge as, at times, a manifestation of a broader human drive to acquire power and exert control.
The Potential for Both Good and Evil: Crucially, Russell recognizes that the increased power derived from knowledge is a double-edged sword. While it can lead to advancements that improve human life, it can also be used for destructive purposes. In discussing the potential for science to enhance happiness, he cautions that “Science has given us powers fit for the gods, yet we remain men, and we use them like small children” [3]. This stark statement underscores his concern that without wisdom and ethical guidance, the immense power unlocked by knowledge can be misused, leading to disastrous consequences.
The Need for Ethical Restraint: To mitigate the potential dangers of knowledge-derived power, Russell emphasizes the importance of ethical considerations in guiding the application of scientific discoveries. He argues that “To see that knowledge is wisely used is primarily the duty of statesmen, not of men of science” [4]. This suggests that he sees a shared responsibility for ensuring that knowledge is used for beneficial purposes. While scientists have a duty to pursue knowledge and share it responsibly, statesmen and policymakers bear the primary responsibility for shaping policies and regulations that guide its application toward ethical and constructive ends.
In summary, Russell’s perspective on the relationship between knowledge and power can be characterized as follows:
He recognizes that knowledge is inherently linked to power, providing the means to control and manipulate aspects of the world.
He acknowledges that the desire for power can be a significant motivating force in the pursuit of knowledge, particularly in scientific fields.
He emphasizes the crucial need for ethical considerations and wisdom to guide the application of knowledge, preventing its misuse and ensuring its contribution to human well-being.
Russell’s insights offer a valuable framework for considering the complexities of this relationship in an age marked by rapid scientific advancements and the immense power they place at our disposal. His perspective urges us to engage in careful reflection on the ethical implications of knowledge and to cultivate the wisdom needed to ensure that its power is harnessed for the betterment of humanity.
34-Two Fundamental Modes of Knowing Things
Bertrand Russell, in his exploration of epistemology, distinguishes between two primary ways we can have knowledge of things:
1. Knowledge by Acquaintance: The Foundation of Knowing
Knowledge by acquaintance is characterized by direct, immediate, and unmediated awareness of an object, without any reliance on descriptions, concepts, or inferences [1]. It’s a form of knowing that doesn’t depend on any other knowledge or truths about the object [1].
What we can know by acquaintance: Russell identifies several categories of objects that we can be acquainted with:
Sense-data: The immediate data of our senses—colors, sounds, smells, textures, etc.—provide the most obvious examples of knowledge by acquaintance [2]. We are directly aware of these sensory experiences.
Introspection: We can also be acquainted with our own internal mental states—thoughts, feelings, desires, etc.—through introspection [3]. This direct awareness of our own minds is the source of knowledge about mental phenomena.
Memory: We can have acquaintance with past sense-data and introspective experiences through memory [4]. Memory allows us to re-experience these past events, bringing them into our present awareness.
(Possibly) The Self: Russell acknowledges the difficulty of defining the self, but suggests that we might have a direct acquaintance with our own “I” as the subject of experiences, although the nature of this acquaintance remains elusive [4].
Key Features of Knowledge by Acquaintance:
Immediacy: The knowing subject is in direct contact with the object of knowledge, without any intermediary [1].
Certainty: Since it doesn’t involve inference or interpretation, knowledge by acquaintance is considered highly certain. We can’t doubt the reality of our immediate experiences [2].
Foundational: Russell argues that all our knowledge, both of things and of truths, ultimately rests upon acquaintance as its foundation [2]. Knowledge by description, as we’ll see, builds upon this foundation.
Limited Scope: Knowledge by acquaintance is confined to the realm of what we directly experience. It doesn’t extend to the wider world of physical objects, other minds, abstract concepts, or anything beyond our immediate sensory or introspective reach [2, 5].
2. Knowledge by Description: Extending Our Reach Through Concepts
Knowledge by description involves knowing an object indirectly, through descriptions, concepts, and propositions that apply to it [6]. It’s a way of knowing something by knowing truths about it, rather than by direct experience [1].
Russell’s Definition of “Description”: A description, for Russell, is any phrase of the form “a so-and-so” (an ambiguous description) or “the so-and-so” (a definite description) [6]. These descriptions serve as our means of referring to and knowing objects that we haven’t directly encountered.
What we can know by description:
Physical Objects: We know physical objects like tables and chairs not by direct acquaintance, but by the sense-data they cause in us, combined with our understanding of the causal laws connecting physical objects and sense-data [6].
Other Minds: We infer the existence and nature of other minds based on our observations of their behavior and our knowledge of the relationship between mental states and behavior [3, 6].
Historical Figures and Events: We learn about historical figures and events through descriptions based on historical records, documents, and accounts [7].
Abstract Concepts: Concepts like “justice,” “infinity,” or “democracy” are grasped through definitions and propositions that relate them to other concepts and experiences [8].
Key Features of Knowledge by Description:
Indirectness: Our awareness of the object is mediated through descriptions, concepts, and truths [6].
Inferential: Knowledge by description relies on drawing inferences based on prior knowledge and reasoning. It involves connecting what we know by acquaintance to what we want to know about the described object [6].
Fallibility: Since it depends on inference and interpretation, knowledge by description is more prone to error than knowledge by acquaintance [9]. Descriptions can be inaccurate, and inferences can be faulty.
Expanded Scope: Knowledge by description is essential for expanding our knowledge beyond the narrow limits of our private experience. It allows us to grasp the world of physical objects, other minds, the past, the future, and the realm of abstract ideas [5].
The Interplay of Acquaintance and Description
While Russell distinguishes between these two modes of knowing, he also recognizes that they are intertwined in our everyday understanding of the world [5]. Our knowledge often involves a dynamic interplay between the immediacy of acquaintance and the conceptual frameworks of description.
For example:
When you see a red apple, you are directly acquainted with the visual sense-datum of “redness,” but you also rely on knowledge by description—concepts of “apple,” “fruit,” “color,” and the causal relationship between objects and sense-data—to fully grasp the object you are perceiving.
When you read a historical account of the French Revolution, you are presented with descriptions of events and individuals, but your understanding of those descriptions depends on your acquaintance with particulars (the words and sentences in the text) and universals (concepts of revolution, political systems, historical actors).
In summary, Russell’s distinction between knowledge by acquaintance and knowledge by description provides a valuable framework for analyzing the different ways we come to know and understand the world around us. While knowledge by acquaintance provides a foundation of immediate certainty, knowledge by description allows us to extend our knowledge far beyond our immediate experience, encompassing a vast realm of objects and concepts.
35-Acquaintance vs. Description: Two Paths to Knowledge
The main difference between knowledge by acquaintance and knowledge by description, as articulated by Bertrand Russell in the sources, lies in the immediacy and directness of our awareness of the object of knowledge.
Knowledge by Acquaintance: Direct and Immediate Awareness
Knowledge by acquaintance involves a direct, unmediated awareness of an object without relying on any inference or knowledge of truths about it [1]. It’s a form of knowing something directly, intimately, without any conceptual or descriptive intermediary.
Examples of acquaintance:Sense-data: The immediate awareness of colors, shapes, sounds, and other sensory experiences [2, 3].
Introspection: Direct awareness of our own thoughts, feelings, and desires [4, 5].
Memory: Direct recall of past experiences, reliving them in our minds [6].
Possibly the Self: Russell suggests that we might have a direct, though elusive, acquaintance with our own “I” as the subject of experiences [5, 7].
Key Characteristics of Knowledge by Acquaintance:
Directness: It’s a direct encounter with the object, not mediated through descriptions or concepts.
Certainty: Since it doesn’t involve inference, knowledge by acquaintance is considered more certain than knowledge by description. We cannot doubt the reality of our immediate experiences.
Limited Scope: Knowledge by acquaintance is confined to what we directly experience through our senses, introspection, or memory. It doesn’t extend to the wider world of physical objects, other minds, or abstract concepts.
Knowledge by Description: Indirect Knowledge via Concepts and Truths
Knowledge by description, in contrast, involves knowing an object indirectly through descriptions, propositions, or concepts that apply to it [1, 3, 8]. It relies on knowledge of truths about the object, connecting it to things with which we have acquaintance.
Defining a Description: Russell defines a “description” as any phrase of the form “a so-and-so” (ambiguous description) or “the so-and-so” (definite description) [8].
Examples of Knowledge by Description:
Physical Objects: We know tables, chairs, and other physical objects through the sense-data they cause in us, combined with our knowledge of the causal connection between physical objects and sense-data [3].
Other Minds: We infer the existence of other minds based on our observations of their behavior and our knowledge of the connection between mental states and behavior [4].
Historical Figures: We know historical figures like Bismarck through descriptions based on historical records, accounts, and testimonies [9, 10].
Abstract Concepts: We grasp concepts like “justice,” “freedom,” or “infinity” through definitions and propositions that relate them to other concepts and experiences [11].
Key Characteristics of Knowledge by Description:
Indirectness: It relies on descriptions and concepts, not direct sensory or introspective experience.
Inferential: It involves drawing conclusions based on prior knowledge and reasoning.
Potential for Error: Since it involves inference, knowledge by description is more prone to error than knowledge by acquaintance. Descriptions can be inaccurate or incomplete, and inferences can be faulty.
Wider Scope: Knowledge by description allows us to extend our knowledge beyond the limits of our immediate experience, encompassing a vast realm of things we haven’t directly encountered.
The Fundamental Principle: All Knowledge Rooted in Acquaintance
Russell argues that even knowledge by description ultimately rests upon a foundation of knowledge by acquaintance [12-14]. Descriptions, he contends, must ultimately be grounded in particulars and universals with which we are directly acquainted. For example, our understanding of a historical figure like Bismarck, known to us by description, relies on our acquaintance with particulars like testimonies we have heard or read, and universals like concepts of political roles, nations, and diplomacy [10].
Bridging the Gap Between Acquaintance and Description
While Russell emphasizes the distinction between these two modes of knowing, he also recognizes that they are often intertwined in our everyday experience. Our knowledge of the world involves a constant interplay between the immediacy of acquaintance and the conceptual frameworks of description. For example, when we perceive a physical object, we are directly acquainted with its sense-data but also rely on descriptive knowledge about the nature of physical objects and their causal connection to sense-data to form a coherent understanding of what we are seeing.
36-A Cautious Optimism: Russell on Science and World Problems
Bertrand Russell recognized the immense potential of science to improve the human condition, but he also cautioned against an overly simplistic view of science as a panacea for all of the world’s ills. He believed that science, while offering powerful tools for solving problems, could also exacerbate existing problems or create new ones if not guided by wisdom, ethical considerations, and a deep understanding of human nature. His views on the potential of science to solve world problems can be characterized as a cautious optimism, tempered by a realistic awareness of the complexities of human affairs and the potential for misuse of scientific knowledge.
The Promise of Science
Throughout the sources, Russell emphasizes the positive contributions of science to human well-being:
Improved Health and Longevity: Science has led to significant advances in medicine, sanitation, and public health, resulting in increased life expectancy and a reduction in the prevalence of many diseases [1, 2].
Technological Advancements: Scientific discoveries and inventions have transformed our lives, providing us with new tools and technologies that have improved our living standards and expanded our horizons. [3]
Increased Understanding of the World: Science has given us a deeper understanding of the natural world, from the vastness of the cosmos to the intricacies of the human brain, expanding our knowledge and enriching our intellectual lives. [4]
Potential for Solving Global Challenges: Russell believed that science held the key to solving pressing global challenges such as poverty, hunger, and disease, provided that scientific knowledge was wisely applied. [5]
The Need for Wisdom and Ethical Guidance
While acknowledging the potential benefits of science, Russell cautioned that science alone was not enough to solve the world’s problems. He stressed the need for:
Wisdom in Application: Scientific knowledge could be used for good or evil, and the choices made about the application of science were ultimately in the hands of human beings, not science itself [6].
Ethical Considerations: Russell believed that scientific progress needed to be guided by ethical principles that prioritized human well-being and sought to minimize harm [7].
Understanding of Human Nature: Scientific solutions to social problems needed to be grounded in a realistic understanding of human nature, taking into account the complexities of human motivation and behavior [8].
The Dangers of Unbridled Scientific Power
Russell was acutely aware of the potential dangers of scientific knowledge falling into the wrong hands or being used for destructive purposes:
The Threat of Nuclear War: He was deeply concerned about the proliferation of nuclear weapons and the potential for a catastrophic global conflict that could destroy human civilization [9].
Misuse of Technology: Russell warned against the potential for technology to be used for oppression, surveillance, and control, undermining human freedom and autonomy [8].
Exacerbation of Social Problems: He recognized that scientific advancements could unintentionally exacerbate existing social problems, such as economic inequality or environmental degradation, if not carefully managed [10].
The Rise of Technocracy: Russell cautioned against the dangers of a technocratic society where decisions were made solely on the basis of technical expertise, without adequate consideration of ethical and social implications [4].
Science as a Tool for Human Progress
Ultimately, Russell saw science as a powerful tool for human progress, but one that needed to be wielded with wisdom, responsibility, and a deep respect for human values. He believed that the key to harnessing the power of science for good lay in:
Promoting Education and Critical Thinking: An educated and scientifically literate public was essential for making informed decisions about the use of science and technology [11].
Cultivating Ethical Values: Societies needed to cultivate ethical values that prioritized human well-being, cooperation, and a respect for the dignity of all individuals [12].
Fostering International Cooperation: Global challenges, such as climate change or nuclear proliferation, required international cooperation and a shared commitment to finding solutions that benefited all of humanity [13].
Taming Power: Russell argued that the key to a better future lay in taming power, both political and economic, and ensuring that it was used to promote human well-being rather than self-interest or domination [14].
In conclusion, Russell believed that science held immense promise for solving world problems, but only if guided by wisdom, ethics, and a deep understanding of human nature. He argued that the future of humanity depended on our ability to harness the power of science for good, while mitigating its potential for harm.
37-The Fundamental Distortion: A Self-Centered Perspective
Bertrand Russell considered the most fundamental distortion in our view of the world to be our egocentric bias, our inherent tendency to see everything from the limited perspective of “the here and now” [1]. This distortion, rooted in our human nature, prevents us from achieving true impartiality and a more objective understanding of the universe.
Limitations of a Self-Centered View
This egocentricity manifests itself in several ways.
Spatial and Temporal Limitations: We tend to prioritize things that are close to us in space and time, often overlooking the vastness of the cosmos and the grand sweep of history [2, 3]. This myopic view leads us to exaggerate our own importance and the significance of our immediate concerns [1].
Emotional Bias: Our emotions, particularly those rooted in self-preservation and self-interest, color our perceptions and judgments, often leading us to prioritize our own needs and desires over those of others [4, 5]. This emotional bias can fuel conflicts and hinder our ability to see situations objectively.
Overemphasis on Human Concerns: We tend to view the world through a distinctly human lens, ascribing human-like qualities and motivations to non-human entities and processes [1, 2]. This anthropocentric perspective can limit our understanding of the natural world and our place within it.
Moving Towards Impartiality
While complete impartiality may be unattainable for humans, Russell believed that we can, and should, strive to move beyond our egocentric limitations [1]. This involves cultivating a broader perspective that acknowledges the vastness of the universe, the interconnectedness of all things, and the limitations of our own knowledge.
He suggests several paths towards achieving greater impartiality:
Expanding Our Horizons Through History and Science: Engaging with history and science can help us to transcend the confines of our immediate experience and appreciate the vastness of time and space [2, 3]. This expanded perspective can help us to see our own lives and concerns in a more balanced light.
Cultivating Reverence for Life: Developing a sense of reverence for all forms of life, particularly for human beings and especially for children, can help us to overcome our ego-driven desires and appreciate the inherent worth and potential of each individual [6].
Embracing Reason and Rejecting Dogmatism: By cultivating intellectual discipline, being willing to admit facts even when they are unpleasant, and rejecting rigid dogmas, we can develop a more objective and nuanced understanding of the world [7]. This involves embracing the scientific method, with its emphasis on evidence and its willingness to revise theories in light of new discoveries [8].
The Ethical Imperative
For Russell, moving towards impartiality was not just an intellectual exercise but an ethical imperative. He believed that our egocentric bias lies at the root of many of the world’s problems, fueling conflicts, injustice, and a disregard for the well-being of others [9]. By cultivating a more impartial and compassionate outlook, we can create a more just and peaceful world.
38-Russell’s Evolving Philosophical Views: A Journey from Mysticism to Logical Analysis
Bertrand Russell’s philosophical journey was marked by significant shifts and transformations as he grappled with fundamental questions about knowledge, reality, and the human condition. His views on philosophy evolved from an early fascination with Hegelian idealism and a Pythagorean-inspired mysticism to a later embrace of logical analysis and a more empirical and scientifically informed perspective. This evolution was shaped by key encounters, intellectual breakthroughs, and a relentless pursuit of clarity and precision in philosophical inquiry.
Early Influences and the Allure of Mysticism
In his youth, Russell was drawn to the grand metaphysical systems of Hegelian idealism, finding solace in the idea of a unified and interconnected universe governed by a higher purpose [1]. He also experienced a period of mystical leanings, influenced by the Pythagorean belief in the profound emotional significance of mathematical logic [2]. This mystical outlook resonated with his yearning for a deeper understanding of the universe and a sense of connection to something larger than himself [3]. His early essay, “A Free Man’s Worship,” reflects this mystical tendency, expressing a sense of awe and wonder in the face of a vast and indifferent cosmos [4].
The Transformative Power of Logic and the 1900 Turning Point
The year 1900 proved to be a pivotal turning point in Russell’s intellectual development, as discussed in our conversation history. His encounter with Giuseppe Peano and symbolic logic at the International Congress of Philosophy in Paris opened his eyes to the power of precise notation and formal systems [5]. This experience led him to realize that symbolic logic could be a powerful tool for analyzing complex concepts and arguments, offering a path towards greater clarity and rigor in philosophical inquiry.
This newfound appreciation for logic and its potential to illuminate philosophical problems marked a significant shift in Russell’s thinking. He began to move away from the grand metaphysical systems of idealism and embrace a more analytical and logic-centered approach to philosophy. His collaboration with Alfred North Whitehead on Principia Mathematica, aimed at reducing mathematics to logic, solidified this shift [6].
Embracing Empiricism and the Limits of Knowledge
As Russell’s engagement with logic deepened, he also became increasingly influenced by empiricism, the view that knowledge is ultimately grounded in sensory experience [7]. This led him to question the traditional philosophical emphasis on ‘truth’ as a static and final concept. Instead, he embraced a more dynamic and process-oriented view of knowledge, emphasizing ‘inquiry’ as the central concept in philosophy [8]. This shift reflected a growing recognition of the limitations of human knowledge and the importance of continuous questioning and revision in the pursuit of understanding.
From Metaphysical Realism to Logical Atomism
Russell’s early leanings towards metaphysical realism, the belief in the independent existence of abstract entities, were challenged by his growing commitment to logical analysis [9]. He developed a view known as logical atomism, which sought to analyze the world into its simplest and most fundamental constituents, or “atoms,” and to understand their logical relationships [10]. This approach, as discussed in the sources, rejected the traditional metaphysical view of ‘substance’ as an underlying and unknowable entity, arguing instead that the world is ultimately composed of events and their logical connections [11].
The Enduring Significance of Science
Throughout his philosophical journey, Russell maintained a deep respect for the scientific method and its power to reveal truths about the natural world [12]. He recognized the importance of integrating scientific knowledge into philosophical inquiry, arguing that philosophy should be informed by the findings of science and should strive to develop a worldview consistent with scientific understanding [13]. This commitment to science is evident in his writings on physics, psychology, and the impact of science on society [14-16].
A Commitment to Clarity and the Rejection of Dogmatism
Perhaps one of the most enduring aspects of Russell’s philosophical approach was his unwavering commitment to clarity and precision in philosophical language [17]. He criticized the obscure and often convoluted language of traditional philosophy, arguing that philosophical problems could be better addressed through careful analysis of language and the logical structure of arguments [18]. This emphasis on clarity and precision is evident in his work on the philosophy of language, where he made significant contributions to our understanding of meaning, reference, and the logical structure of propositions [19, 20].
This commitment to clarity was closely tied to his rejection of dogmatism and his willingness to revise his views in light of new evidence or arguments [17, 21]. He recognized that philosophical inquiry is an ongoing process and that any claim to absolute certainty is likely to be misplaced [22]. This openness to revision is evident in his own philosophical development, as he readily acknowledged his changing views on various issues throughout his life [2, 21].
Conclusion: A Legacy of Reason and Humanism
Bertrand Russell’s philosophical journey exemplifies the dynamism and evolution of thought that characterize the best philosophical inquiry. His willingness to question established ideas, his rigorous pursuit of clarity, and his integration of scientific insights into philosophical reflection left an indelible mark on the 20th-century philosophical landscape. His legacy continues to inspire those seeking a philosophy grounded in reason, evidence, and a deep concern for the human condition.
39-A Pivotal Year: 1900 in Russell’s Intellectual Life
The year 1900 stands out as a landmark in Bertrand Russell’s intellectual journey, marking a significant shift in his philosophical outlook and setting the stage for his future contributions to logic, mathematics, and philosophy. Here’s why 1900 was so crucial:
Encounter with Peano and Symbolic Logic: Russell describes his visit to the International Congress of Philosophy in Paris in 1900 as a transformative event. He was particularly impressed by the precision and rigor of Italian mathematician Giuseppe Peano and his students, who were proponents of symbolic logic. This encounter exposed Russell to a new way of thinking about mathematics and logic, one that emphasized formal systems and symbolic representation.
The Power of Precise Notation: Russell immediately recognized the potential of Peano’s notation to extend mathematical precision into areas previously dominated by philosophical vagueness. He realized that symbolic logic could provide a powerful tool for analyzing complex concepts and arguments, allowing for greater clarity and rigor in philosophical inquiry. This realization ignited his interest in the foundations of mathematics and led him to collaborate with Alfred North Whitehead on the monumental work, Principia Mathematica.
From Metaphysical Realism to Logical Analysis: Before 1900, Russell had been heavily influenced by Hegelian idealism and held a metaphysical realist perspective, believing in the timeless existence of abstract entities like numbers and classes. However, his growing interest in symbolic logic and its focus on formal systems led him to question these metaphysical assumptions. He began to see the limitations of traditional philosophical methods and the potential of logical analysis to address philosophical problems with greater precision.
Shifting Focus from Metaphysics to Logic: Russell’s work on Principia Mathematica involved reducing mathematics to logic, demonstrating that mathematical concepts could be defined and theorems proven using a purely logical framework. This project further solidified his shift away from metaphysical realism towards a more analytical and logic-centered approach to philosophy.
The Seeds of ‘The Theory of Descriptions’: In 1900, Russell also encountered the work of Austrian philosopher Alexius Meinong, whose “theory of objects” posited the existence of non-existent objects. While initially intrigued, Russell eventually rejected Meinong’s view as overly populated with “being.” This encounter, however, planted the seeds for Russell’s later development of “the theory of descriptions,” a groundbreaking contribution to the philosophy of language that clarified the logical structure of language and helped resolve certain paradoxes.
In essence, the year 1900 marked a turning point for Russell. He moved away from the grand metaphysical systems of idealism and embraced the rigor and precision of symbolic logic, setting the stage for his groundbreaking work in logic, mathematics, and the philosophy of language.
40-William James’ Influence: A Catalyst for Change
The provided sources primarily focus on Bertrand Russell’s philosophical journey and don’t offer specific details about William James’ impact on the philosophical world. However, they do provide some glimpses into his influence, particularly in the context of the philosophical landscape of the early 20th century. Here’s what can be gleaned from the sources:
Challenging German Idealism: The sources highlight the dominance of German idealism, particularly the philosophies of Kant and Hegel, in academic circles during the late 19th and early 20th centuries. Russell acknowledges the initial appeal of these systems but eventually moves away from them [1]. He credits William James as a significant figure in the shift away from German idealism, particularly through his later works, which championed a more empirical and pragmatic approach [2].
Championing Pragmatism: The sources identify William James as a leading figure in the pragmatist movement, alongside Schiller and Dewey [3, 4]. They describe pragmatism as a philosophical approach that emphasizes the practical consequences of beliefs and theories, prioritizing their usefulness and effectiveness in guiding action over their correspondence with absolute truth [5]. This pragmatic approach, as advocated by James, resonated with those seeking a more experience-based and less abstract approach to philosophy.
Shifting Focus From ‘Truth’ to ‘Inquiry’: While discussing John Dewey, the sources note that Dewey, like William James, moved away from the traditional focus on ‘truth’ as a static and final concept. They both embraced a more dynamic and process-oriented view of knowledge, emphasizing ‘inquiry’ as the central concept in philosophy [6]. This shift reflected a broader movement away from the pursuit of absolute certainty towards a more tentative and evolving understanding of knowledge.
Influence on Bertrand Russell: While Russell ultimately diverged from James on certain philosophical points, he acknowledges the influence of James’ “radical empiricism” in the development of the “new realism” movement, which advocated for a pluralistic and less idealistic view of the world [7]. This suggests that James’ ideas, even when not fully embraced by Russell, played a role in shaping the direction of his own philosophical thinking.
It’s important to note that the sources offer a limited perspective on William James’ influence, primarily within the context of Bertrand Russell’s own philosophical development. A more comprehensive understanding of James’ impact on the philosophical world would require exploring sources specifically dedicated to his work and his contributions to pragmatism, psychology, and other areas of thought.
41-The Catalyst for Russell’s Loss of Faith
Bertrand Russell attributes his loss of religious faith to a specific moment when he was 18 years old, triggered by a sentence he encountered in John Stuart Mill’s Autobiography [1-3]. Before this pivotal moment, Russell had believed in a Deist God, finding the “First-Cause Argument” compelling [2]. This argument posits that everything in existence must have a cause, leading back to an ultimate First Cause, which is identified as God.
However, Mill’s simple statement, recounting a lesson from his father James Mill, exposed what Russell perceived as a flaw in this argument. The sentence that resonated so deeply with Russell was: “My father taught me that the question ‘Who made me?’ cannot be answered, since it immediately suggests the further question ‘Who made God?’” [3]
This realization, that the First-Cause Argument failed to address the origin of God, led Russell to abandon his belief in God at the age of 18 [4]. He concluded that if everything requires a cause, then God must also have a cause, rendering the argument invalid. He reasoned that if something could exist without a cause, it could just as easily be the world as God [5].
This encounter with Mill’s Autobiography marked a turning point in Russell’s intellectual journey. It’s worth noting that this pivotal sentence came from someone who had a close relationship with his own parents, as John Stuart Mill was a close friend of Russell’s father and mother [2]. This connection likely added further weight to Mill’s words, reinforcing the impact of the argument on Russell’s thinking.
42-Judging an Industrial System: Russell’s Four Tests
Bertrand Russell outlines four key tests to evaluate the effectiveness of an industrial system, whether it’s the existing system or one proposed by reformers [1]:
Maximum Production: This test assesses the system’s ability to generate the highest possible output of goods and services. It focuses on efficiency and productivity as key indicators of economic success.
Justice in Distribution: This test examines how equitably the system distributes the wealth and resources it generates. It considers whether the system ensures a fair allocation of benefits and burdens among different social groups.
A Tolerable Existence for Producers: This test focuses on the well-being of the workers within the system. It assesses whether the system provides workers with decent working conditions, fair wages, reasonable working hours, and overall a quality of life that avoids exploitation and misery.
Freedom and Stimulus to Vitality and Progress: This test evaluates the system’s impact on individual freedom, creativity, and innovation. It considers whether the system encourages personal initiative, allows for individual growth and development, and promotes social progress through innovation and technological advancement.
Russell argues that the existing industrial system primarily prioritizes maximum production, often at the expense of the other three factors [1]. He suggests that socialism aims to improve justice in distribution and the well-being of producers, but might still fall short in ensuring individual freedom and promoting progress [1].
He ultimately advocates for a system that balances all four factors, allowing for economic efficiency while ensuring social justice, worker well-being, and individual freedom [2]. He envisions a system that restricts the power of landowners and capitalists while promoting worker ownership and control, fostering a sense of pride in work and unleashing creativity [2].
43-Critiques of Traditional Ethical Theories
While the sources don’t explicitly outline a systematic critique of all traditional ethical theories, they do offer insights into Russell’s critical perspective on certain aspects of traditional ethics, particularly those with religious foundations.
Rejection of Absolute Moral Rules: Russell challenges the notion of universal and absolute moral rules, particularly in the realm of sexual ethics. He argues that moral beliefs have historically been tied to economic systems and have evolved over time. He observes that moral views on issues like marriage and sexuality often reflect the economic conditions prevalent three generations prior [1]. This historical perspective, he argues, undermines the claim that contemporary moral codes represent eternal truths. He further critiques the rigid and often hypocritical application of these rules, citing examples of individuals deemed “wicked” for minor transgressions while overlooking the harmful actions of those who technically adhere to the rules [2]. He advocates for a more flexible and nuanced approach to morality that considers context and consequences rather than blind adherence to rigid codes.
Critique of Sin and Virtue: Russell criticizes the traditional religious concepts of sin and virtue, seeing them as rooted in fear and a negative view of human nature [3]. He challenges the idea that virtue requires the suppression of natural impulses, arguing instead for an ethic based on positive values like intelligence, sanity, kindness, and justice [4]. He believes that a healthy individual should not be driven by a fear of sin but should instead develop naturally towards non-harmful behavior.
Challenge to Religious Authority in Ethics: Russell questions the authority of religious institutions in dictating moral principles. He argues that religious teachings, often based on dogma and superstition, can hinder intellectual and moral progress [5]. He contends that reliance on religious authority stifles critical thinking and perpetuates harmful beliefs, particularly in matters of sexual morality.
Emphasis on Reason and Human Well-being: Throughout his writings, Russell advocates for a more rational and humanistic approach to ethics, grounded in human experience and focused on promoting well-being. He rejects the notion of morality as a set of divinely ordained rules, instead favoring an approach that considers the consequences of actions and their impact on human happiness. He emphasizes the importance of individual liberty and the freedom to pursue a good life guided by reason and compassion.
Although the sources provide a glimpse into Russell’s critical perspective on certain aspects of traditional ethics, it’s important to note that they don’t offer a comprehensive critique of every traditional ethical theory. Further exploration of his works might reveal more detailed and systematic critiques.
44-A Critical Perspective on Religion Informed by Science
Bertrand Russell views science and religion as fundamentally opposed forces, with science representing a rational and evidence-based approach to understanding the world, while religion, in his view, relies on dogma, superstition, and an unwillingness to question traditional beliefs. Throughout his writings, he critiques religion from a scientific and humanistic perspective, highlighting the harm he believes it inflicts on individuals and society.
Science as a Source of Truth and Progress: Russell consistently champions science as the best method for acquiring knowledge about the world. He emphasizes the importance of observation, logical reasoning, and a willingness to adapt theories based on new evidence. This scientific approach, he argues, has led to significant advancements in human understanding and the betterment of human life. [1, 2]
Religion as a Barrier to Progress: In contrast, Russell views religion as a hindrance to intellectual and moral progress. He argues that religious doctrines, often rooted in ancient and outdated beliefs, discourage critical thinking and perpetuate harmful superstitions. He particularly criticizes the tendency of religious institutions to resist scientific advancements that challenge their authority. [3, 4]
The Conflict Between Reason and Faith: Russell sees a fundamental incompatibility between the rational inquiry of science and the reliance on faith in religion. He argues that religious beliefs, based on dogma and revelation, cannot withstand the scrutiny of scientific evidence and logical analysis. He criticizes the attempts to reconcile science and religion, believing that such efforts ultimately undermine the integrity of both. [5, 6]
The Ethical Implications of Religion: Russell criticizes the moral teachings of traditional religions, arguing that they often promote intolerance, cruelty, and a disregard for human well-being. He points to historical examples of religious persecution, the role of religion in justifying war and violence, and the opposition of religious institutions to social progress in areas such as sexual morality and reproductive rights. [4, 7, 8]
The Psychological Roots of Religious Belief: Russell explores the psychological motivations behind religious belief, suggesting that fear, the desire for comfort, and the longing for a sense of purpose drive many people to seek solace in religion. He argues that these emotional needs can be met through other means, such as humanism and a scientific understanding of the world. [9, 10]
Russell’s views on the relationship between science and religion are shaped by his broader philosophical outlook, which emphasizes reason, humanism, and a commitment to individual liberty. He sees science as a powerful tool for promoting human progress and criticizes religion for its role in perpetuating ignorance, superstition, and harmful social norms.
45-Russell’s Critique of “Common Usage” in Philosophy
Bertrand Russell argues against the “cult of ‘common usage’” in philosophy, finding it insufficient for rigorous philosophical inquiry. He outlines his critique in source [1], presenting five key objections:
Insincerity: He contends that proponents of “common usage” often use specialized language themselves, particularly when discussing fields like medicine. Russell provides an anecdote about a philosophy professor suffering a mental breakdown, where a “common usage” advocate readily adopts the doctor’s technical diagnosis when describing the situation to others. [2]
Excusing Ignorance: Russell asserts that “common usage” can be used to justify a lack of knowledge in essential fields such as mathematics, physics, and neurology. This is particularly problematic for individuals with solely classical educations. He argues that philosophy, like any discipline, requires specialized language and concepts to address complex issues adequately. [2]
False Appeal to Democracy: Russell criticizes the self-righteous tone adopted by some “common usage” proponents, who imply that opposing their view is somehow undemocratic. He counters this by stating that philosophy should not shy away from exploring complex concepts simply because they might seem elitist. He emphasizes that philosophy’s goal is to seek truth, not to pander to popular opinion. [3]
Trivializing Philosophy: Russell believes that relying solely on “common usage” reduces philosophy to a shallow exercise. He argues that philosophy must engage with profound questions, and that often, these questions require moving beyond everyday language and concepts. He fears that the oversimplification inherent in “common usage” leads to a superficial understanding of philosophical issues. [4]
Perpetuating Muddle-Headedness: Russell contends that “common usage” often carries inherent confusion and ambiguity. He uses examples like the location of a rainbow or the nature of pain in an amputated limb to illustrate the inherent inconsistencies within common sense. He argues that philosophy, by its nature, should aim to clarify and analyze these issues, requiring a move beyond everyday language and assumptions. [5]
Russell ultimately argues that philosophy, like any rigorous discipline, necessitates a specialized vocabulary and a willingness to challenge common-sense assumptions. While acknowledging the value of everyday language, he believes that it is inadequate for addressing complex philosophical issues. He emphasizes that clinging to “common usage” limits the scope and depth of philosophical inquiry, leading to trivialization and a perpetuation of pre-existing misunderstandings.
46-Purposes of Social Activities: Security and Progress
According to Bertrand Russell, the two main purposes of social activities are:
Security and justice. These require centralized governmental control, ideally extending to a world government for maximum effectiveness. [1]
Progress. This requires the greatest possible scope for personal initiative compatible with social order. [1]
To achieve a balance between these often-conflicting goals, Russell advocates for devolution:
A world government should focus on preventing war, leaving other matters to national governments. [1]
National governments should devolve power to local authorities whenever possible. [1]
Large industries, such as railways, should have significant self-governance. [1]
Freedom of opinion in areas like media and political discourse is crucial and must be protected from governmental control and monopolies. [1]
This structure, Russell believes, allows for the efficient maintenance of security and justice while simultaneously fostering individual initiative and progress.
47-Examining the Impact of Science on Society in Russell’s Works
The sources, which largely consist of Bertrand Russell’s writings, explore the profound impact of science on society, both in terms of its potential benefits and its capacity for destruction. Russell argues that science, while offering the possibility of immense human progress, also presents unprecedented dangers, requiring careful consideration of its social and ethical implications. He advocates for a scientific outlook that embraces critical thinking, reason, and a commitment to human welfare.
Science as a Liberator and a Threat
Russell recognizes the liberating potential of science, highlighting its ability to alleviate suffering, improve living conditions, and expand human understanding. He sees scientific knowledge as one of humanity’s greatest achievements and emphasizes its power to combat poverty, disease, and ignorance [1, 2].
However, he also acknowledges the dangerous aspects of scientific progress, particularly its potential for misuse in warfare and the creation of technologies that threaten human existence. He expresses deep concern about the development of nuclear weapons and the possibility of their use leading to global annihilation [1, 3, 4].
He warns against “cleverness without wisdom” [5], arguing that scientific advancements without corresponding ethical and social progress can lead to disastrous consequences. He sees the potential for science to be used for both good and evil, emphasizing the importance of directing scientific knowledge towards beneficial ends [6, 7].
The Need for a Scientific Outlook in Politics and Society
Russell advocates for a scientific approach to social and political issues, emphasizing the importance of observation, evidence-based reasoning, and a willingness to adapt to changing circumstances. He criticizes the tendency of politicians to cling to outdated ideologies and rely on emotional appeals rather than rational arguments [8, 9].
He argues that scientific thinking should guide decision-making in areas such as economics, education, and international relations, urging a shift away from traditional, often superstitious, approaches to these challenges [10, 11].
He stresses the need for greater public understanding of science, recognizing that informed citizens are essential for making responsible choices about the use of scientific knowledge and technology. He advocates for education systems that promote critical thinking and scientific literacy [12, 13].
He calls for scientists to play a more active role in shaping public policy, urging them to engage with society, communicate their findings, and advocate for the responsible use of scientific knowledge. He emphasizes the moral responsibility of scientists to use their expertise to benefit humanity and prevent the misuse of their discoveries [7, 14-17].
The Impact of Technology on Human Life
Russell recognizes the transformative impact of technology on human life, noting that scientific advancements have led to profound changes in the way people live, work, and interact with each other. He emphasizes the need for society to adapt to these changes and develop new social structures and institutions that can effectively manage the challenges posed by technological progress [9, 11].
He expresses concern about the potential for technology to dehumanize society, warning against excessive reliance on machines and the erosion of individual creativity and autonomy. He argues for a balance between technological progress and human values, advocating for the use of technology to enhance human well-being rather than diminish it [18, 19].
The Importance of Ethical Considerations
Russell stresses the importance of ethical considerations in the application of scientific knowledge. He argues that science alone cannot determine the ends of human life and that moral values must guide the choices made about how scientific discoveries are used [20-22].
He criticizes the view that science is value-neutral, arguing that scientists have a moral responsibility to consider the potential consequences of their work and advocate for its ethical use. He calls for a greater awareness of the social and ethical implications of scientific progress, urging scientists and policymakers to work together to ensure that science is used to benefit humanity [21, 23].
The Tension Between Individuality and Social Control
Russell recognizes the tension between individual freedom and the need for social control in a scientific age. He acknowledges that technological advancements and the growing complexity of society may require limitations on individual liberty in order to maintain order and stability [11].
However, he also emphasizes the importance of preserving individual initiative and creativity, arguing that a society overly focused on control and uniformity would stifle progress and undermine human happiness. He advocates for a balance between individual freedom and social responsibility, seeking ways to harness the power of science while protecting human dignity and autonomy [24, 25].
The Future of Science and Society
Russell expresses both hope and fear about the future of science and society. He sees the potential for science to create a world free from poverty, disease, and war, but also recognizes the risk that scientific knowledge could be used to destroy humanity [26, 27].
He emphasizes the importance of human choices in determining the course of scientific progress, arguing that whether science leads to utopia or dystopia depends on the values and decisions of individuals and societies. He calls for a conscious effort to direct scientific knowledge towards beneficial ends, urging a commitment to peace, cooperation, and the pursuit of human well-being [28, 29].
Concluding Thoughts
The sources reveal Russell’s complex and nuanced view of the relationship between science and society. While recognizing the transformative power of science and its potential for both good and evil, he emphasizes the importance of ethical considerations, social responsibility, and a scientific outlook that embraces critical thinking, reason, and a commitment to human welfare.

Saudi Real Estate Finance and Vision 2030
Real Estate Finance is identified in the sources as a fundamental pillar of Saudi Arabia’s comprehensive national development project, Vision 2030, which aims to increase the rate of residential ownership to 70% by 2030. The stability of the real estate market and the family unit is a primary concern for the leadership.
The discussion of real estate finance covers the existing Saudi model, recent government interventions to stabilize the market, and international comparisons that highlight areas for development.
The Saudi Real Estate Finance Model
The Kingdom’s approach relies heavily on government support and rapid market growth:
Market Size and Growth: The volume of real estate finance in Saudi Arabia reached approximately $226 billion in 2024, demonstrating a robust annual growth rate of 13%.
The “Sakani” Program: The government provides subsidized loans through the “Sakani” program, which offers low-interest rates (ranging from 3% to 5%) and financing up to 90% of the property value for first-time buyers.
Liquidity Mechanism: The Saudi Real Estate Refinance Company (SRC) plays a key role by purchasing new issue loans from banks to provide liquidity. While this system is considered effective, the secondary market for mortgage-backed financial securities (MBS) is less developed compared to markets like the United States.
Policies for Market Stabilization and Balance
The Kingdom has taken decisive action to address market volatility and ensure housing stability, particularly in response to rapid price escalation.
1. Addressing Price and Supply Imbalances
The market, especially in Riyadh, experienced high volatility, with real estate prices recording the highest change rate in the Kingdom at 10.7% in the first quarter of the current year. This rapid increase was attributed to high demand and a shortage of real estate supply.
To mitigate these issues, policies were introduced that:
Encourage Investment: Policies were put in place to discourage land hoarding (“treasuring it”) and promote real investment.
Increase Supply: Measures included lifting the suspension on throwing (selling) lands in Riyadh and other areas (covering over 81 million square meters), which is expected to increase the supply of real estate and subsequently lead to a reduction in prices.
2. Stabilizing Rental Values (Tackling the Price Surge)
Recent directives were issued to stabilize the rental market, which had suffered from arbitrary and unsupported price increases.
Tackling Monopolistic Practices: The new regulations aim to break non-standard pricing and monopolistic practices.
Fixed Rental Value: A key measure is the fixing of the rental value for both residential and commercial properties for a period of five years (effective from September 2025).
Protection for Tenants: This aims to enable tenants (individuals and businesses) to plan financially over the medium term without unexpected increases, thereby stabilizing the financial planning of small and medium-sized companies, especially in the retail sector.
“Ejar” Platform: The regulations require mandatory contract documentation on the “Ejar” platform to preserve the rights of all parties involved.
These policies reflect a high degree of flexibility and efficiency on the part of the government to intervene with solutions that ultimately benefit the public.
Global Comparisons and Future Development Needs
A review of global real estate finance models highlights the areas where the Saudi model could evolve to achieve the goals of Vision 2030:
Global ModelKey FeatureComparison/Insight for Saudi ArabiaSource(s)United StatesHighly competitive market, strong secondary market for MBS.Saudi Arabia needs to develop its secondary market to increase liquidity and potentially lower interest rates (currently higher than US rates due to risk calculation).China & SingaporeReliance on mandatory savings schemes (CPF/Housing Fund) to support loans.Saudi Arabia lacks a comprehensive mandatory savings system. Implementing such a system could reduce reliance on external debt and protect against interest rate fluctuations.GermanyStable market relying on “Bausparverträge” (savings contracts) with fixed, low-interest rates.Germany offers greater stability. Saudi Arabia needs a similar regulated savings system to protect against inflation in interest rates.FranceGovernment-backed interest-free loans for first-time buyers (PTZ).The Saudi “Sakani” loans are subsidized but have low interest; France’s model provides an example of maximizing youth support through zero-interest options, which should be linked to sustainability criteria.JapanStable long-term loans (up to 100 years), benefiting from lessons learned during past asset bubbles.Japan’s focus on long-term stability and avoiding bubbles is valuable. Saudi Arabia needs to focus on long-term loans to enhance stability.Recommendations for Improvement:
Based on international comparisons, the sources suggest that the Saudi model could be enhanced by:
Developing a strong secondary market for financial securities.
Launching a national compulsory savings program to target youth (18–35 years).
Offering interest-free government loans for housing.
Accelerating digitization of finance services (using rapid technology adoption like the UK and Japan) and enhancing financial market oversight.
World Teachers’ Day and Saudi Vision 2030
The sources discuss the observance and significance of the Teacher’s Global Day (or World Teachers’ Day) and the central role of the teacher in national development, particularly within the context of Saudi Arabia.
Global Observance and Historical Context

Python Programming and Web Scraping Tutorial
Okay, I have reviewed the provided text and here’s a briefing document summarizing its main themes and important ideas:
Briefing Document: Python Basics and Web Scraping Tutorial
Overall Theme:
This document contains the script for a video tutorial aimed at teaching beginners the fundamentals of Python programming, including setting up the environment, covering core concepts, and introducing web scraping with Beautiful Soup. The tutorial is structured as a hands-on lesson, walking the viewer through installing Anaconda, using Jupyter Notebooks, understanding variables, data types, operators, control flow (if/else, for loops, while loops), functions, data type conversions, and finally applying these skills to a web scraping project.
Key Ideas and Facts:
Setting up the Python Environment:
The tutorial recommends installing Anaconda, describing it as “an open source distribution of python and our products. So within Anaconda is our jupyter notebooks as well as a lot of other things but we’re going to be using it for our Jupiter notebooks.”
It walks through the Anaconda installation process, emphasizing the importance of selecting the correct installer for the operating system (Windows, Mac, or Linux) and system architecture (32-bit or 64-bit).
Introduction to Jupyter Notebooks:
Jupyter Notebooks are the primary environment for writing and executing Python code in the tutorial. “Right here is where we’re going to be spending 99% of our time in future videos this is where we’re going to write all of our code.”
Notebooks are comprised of “cells” where code or markdown can be written.
Markdown is introduced as a way to add comments and organization to the notebook: “markdown is its own kind of you could say language but um it’s just a different way of writing especially within a notebook.”
Basic notebook operations are explained, including saving, renaming, inserting/deleting cells, copying/pasting cells, moving cells, running code, interrupting the kernel, and restarting the kernel.
Python Variables:
A variable is defined as “basically just a container for storing data values.”
Variables are dynamically typed in Python, meaning the data type is automatically assigned based on the value assigned to the variable.
Variables can be overwritten with new values.
Multiple variables can be assigned values simultaneously (e.g., x, y, z = 1, 2, 3).
Multiple variables can be assigned the same value (e.g., x = y = z = “hello”).
Lists, dictionaries, tuples, and sets can all be assigned to variables.
The tutorial covers naming conventions such as camel case, Pascal case, and snake case, recommending snake case for readability: “when I’m naming variables I usually write it in snake case because I just find it a lot easier to read because each word is broken up by this underscore”.
It also covers invalid naming practices and what symbols can be used within variable names.
Strings can be concatenated using the + operator, but you can’t directly concatenate strings and numbers within a variable assignment (you can in a print statement using commas).
Python Data Types:
The tutorial covers the main data types in Python.
Numeric: Integers, floats, and complex numbers.
Boolean: True or False values.
Sequence Types: Strings, lists, and tuples.
Set: Unordered collections of unique elements.
Dictionary: Key-value pairs.
Strings can be defined with single quotes, double quotes, or triple quotes (for multi-line strings). Strings are arrays of bytes representing Unicode characters.
Indexing in strings starts at zero and can use negative indices to access characters from the end of the string. Slicing also works.
Lists are mutable, meaning their elements can be changed after creation using their indexes. Lists are index just like a string is. “One of the best things about lists is you can have any data type within them.”
Tuples are immutable, and lists and tuples are very similar with that being one main exception. “typically people will use tupal for when data is never going to change”.
Sets only contain unique values and are unordered.
Dictionaries store key-value pairs, and values are accessed by their associated keys. Dictionaries are changeable. “within a data type we have something called a key value pair… we have a key that indicates what that value is attributed to”.
Operators:
Comparison Operators: Used to compare values (e.g., ==, !=, >, <, >=, <=).
Logical Operators: Used to combine or modify boolean expressions (and, or, not).
Membership Operators: Used to check if a value exists within a sequence (in, not in).
Control Flow:
If/Elif/Else Statements: Used to execute different blocks of code based on conditions. The tutorial mentions “You can have as many ill if statements as you want but you can only have one if statement and one else statement”. Nested if statements are also covered.
For Loops: Used to iterate over a sequence, the diagram in the text walks through this, ending in “exit the loop and the for loop would be over”.
While Loops: Used to repeatedly execute a block of code as long as a condition is true. Break statements, continue statements, and using else statements to create a “counter” are also covered.
Functions:
Functions are defined using the def keyword.
Arguments can be passed to functions.
The tutorial describes many types of arguments including custom arguments, multiple arguments, arbitrary arguments, and keyword arguments. Arbitrary arguments use *args, and arbitrary keyword arguments use **kwargs.
Data Type Conversion:
Functions like int(), str(), list(), tuple(), and set() are used to convert between data types. This is important because the tutorial also says “it cannot add both an integer and a string.” Converting a list to a set automatically removes duplicate elements.
BMI Calculator Project:
The tutorial walks through building a BMI calculator.
The program takes user input for weight (in pounds) and height (in inches).
The BMI is calculated using the formula: weight * 703 / (height * height).
The program then uses if/elif/else statements to categorize the BMI into categories like underweight, normal weight, overweight, obese, severely obese, and morbidly obese.
The program uses input() for user input, which is then converted to an integer.
Web Scraping Project:
Introduction to Web Scraping: Web scraping is the process of extracting data from websites.
Libraries Used:requests: Used to send HTTP requests to retrieve the HTML content of a webpage.
Beautiful Soup: Used to parse the HTML content and make it easier to navigate and extract data. “Beautiful Soup takes this messy HTML or XML and makes it into beautiful soup”.
pandas: Used for data manipulation and analysis, specifically creating a DataFrame to store the scraped data. “We can use Pandas and manipulate this”.
Steps in Web Scraping:Send a Request: Use the requests library to get the HTML content of the target webpage.
Parse the HTML: Use Beautiful Soup to parse the HTML content into a navigable data structure.
Locate Elements: Use Beautiful Soup’s methods (e.g., find(), find_all()) to locate the specific HTML elements containing the data you want to extract.
Extract Data: Extract the text or attributes from the located HTML elements.
Store Data: Store the extracted data in a structured format, such as a pandas DataFrame or a CSV file.
Key Beautiful Soup Methods:find(): Finds the first element that matches the specified criteria.
find_all(): Finds all elements that match the specified criteria.
HTML Element Attributes: The tutorial mentions the importance of HTML element attributes (e.g., class, href, id) for targeting specific elements with Beautiful Soup.
Targeting Elements with Classes: The .find() and .find_all() methods can be used to select elements based on their CSS classes.
Navigating HTML Structure: The tutorial demonstrated how to navigate the HTML structure to locate specific data elements, particularly focusing on table, tr (table row), and td (table data) tags.
Data Cleaning: The tutorial showed how to clean up the extracted data by stripping whitespace from the beginning and end of the strings.
Creating Pandas DataFrame: The scraped data is organized and stored into a pandas DataFrame.
Exporting Data to CSV: The tutorial shows how to export the data in a data frame to a CSV file.
Quotes:
“Right here is where we’re going to be spending 99% of our time in future videos this is where we’re going to write all of our code.”
“a variable is basically just a container for storing data values.”
“when I’m naming variables I usually write it in snake case because I just find it a lot easier to read because each word is broken up by this underscore”
“typically people will use tupal for when data is never going to change”
“Beautiful Soup takes this messy HTML or XML and makes it into beautiful soup”
“we can use Pandas and manipulate this”
“It cannot add both an integer and a string”
Overall Assessment:
The provided text outlines a comprehensive introductory Python tutorial suitable for individuals with little to no prior programming experience. It covers a wide range of essential concepts and techniques, culminating in practical projects that demonstrate how these skills can be applied. The step-by-step approach and clear explanations, supplemented by hands-on examples, should make it accessible and engaging for beginners. However, some familiarity with HTML is assumed for the web scraping portion.

Variables are containers for storing data values. They are useful because they allow you to assign a name to a value (like a number, string, or list) and then refer to that value throughout your code by using the variable name, without having to rewrite the value itself.
4. How does Python automatically determine the data type of a variable, and what are some common data types?
Python uses dynamic typing, meaning it automatically infers the data type of a variable based on the value assigned to it. Common data types include integers (whole numbers), floats (decimal numbers), strings (text), Booleans (True/False), lists, dictionaries, tuples, and sets.
Python Fundamentals & Usage
5. What are the key differences between lists, tuples, and sets in Python?
Lists: Ordered, mutable (changeable) collections of items. They allow duplicate values.
Tuples: Ordered, immutable (unchangeable) collections of items. They also allow duplicate values.
Sets: Unordered collections of unique items. Sets do not allow duplicate values.
6. What are comparison, logical, and membership operators in Python, and how are they used?
Comparison Operators: Used to compare values (e.g., == (equal), != (not equal), > (greater than), < (less than)). They return Boolean values (True or False).
Logical Operators: Used to combine or modify Boolean expressions (e.g., and, or, not).
Membership Operators: Used to test if a value is present in a sequence (e.g., in, not in).
7. Explain the purpose of if, elif, and else statements in Python, and how they control the flow of execution.
if, elif (else if), and else statements are used to create conditional blocks of code. The if statement checks a condition, and if it’s true, the code block under the if statement is executed. elif allows you to check additional conditions if the previous if or elif conditions were false. The else statement provides a default code block to execute if none of the if or elif conditions are true.
8. How do for and while loops work in Python, and what are the differences between them?
for Loops: Used to iterate over a sequence (like a list, tuple, or string) and execute a block of code for each item in the sequence.
while Loops: Used to repeatedly execute a block of code as long as a specified condition is true. The loop continues until the condition becomes false.
The main difference is that for loops are typically used when you know in advance how many times you want to iterate, while while loops are used when you want to repeat a block of code until a specific condition is no longer met.
Creating Jupyter Notebooks with Anaconda
To create a notebook in Anaconda using jupyter notebooks, these steps can be followed:
Download Anaconda, which is an open source distribution of Python and R products, from the Anaconda website. Make sure to select the correct installer for your operating system (Windows, Mac, or Linux). For Windows users, it’s important to check the system settings to determine if it’s a 32-bit or 64-bit system.
Install Anaconda by clicking ‘next’ on the installer window. Review the license agreement and click ‘I agree’. Choose the installation type, either for the current user only or for all users on the computer. Select the file path for the installation, ensuring there is enough disk space (approximately 3.5 GB).
In the advanced options, it is not recommended to add Anaconda to the path environment variable unless you are experienced with Python. It is safe to register Anaconda as the default Python version. Allow the installation process to complete.
After the installation is complete, search for and open Anaconda Navigator.
In Anaconda Navigator, launch jupyter Notebook. This will open a new tab in the default web browser. If this is the first time opening jupyter Notebook, the file directory may be blank.
In the jupyter Notebook interface, go to the ‘new’ drop down and select ‘Python 3 (ipykernel)’ to create a new notebook with a Python 3 kernel.
A new jupyter Notebook will open where code can be written. This is where code will be written in future tutorials.
In the notebook, there are cells where code can be typed. To run the code in a cell, press Shift + Enter.
Besides writing code, markdown can be used to add comments and organize the notebook. To use markdown, type a hashtag/pound sign (#) followed by the text.
After creating a jupyter Notebook, the title can be changed by clicking on the name at the top of the page. It is also possible to insert cells, delete cells, copy and paste cells and move cells up or down.
Python Code: Concepts and Web Scraping
Python code involves several key concepts, including variables, data types, operators, control flow (if statements, loops), functions, and web scraping.
Variables:
Are containers for storing data values, such as numbers or strings.
A value can be assigned to a variable using the equal sign (=), for example, x = 22 assigns the value 22 to the variable x.
The print() function displays the value of a variable. For example, print(x) would output 22 if x has been assigned the value of 22.
Python automatically assigns a data type to a variable based on the assigned value.
Variables can be overwritten with new values.
Variables are case-sensitive.
Multiple values can be assigned to multiple variables. For example, x, y, z = “chocolate”, “vanilla”, “rocky road” assigns “chocolate” to x, “vanilla” to y, and “rocky road” to z.
Multiple variables can be assigned to one value. For example, x = y = z = “root beer float” assigns “root beer float” to all three variables.
Variables can be used in arithmetic operations. For example, y = 3 + 2 assigns the value 5 to the variable y.
Variables can be combined within a print statement using the + operator for strings or commas to combine different data types.
Data Types:
Are classifications of the data that you are storing.
Numeric data types include integers, floats, and complex numbers.
Integers are whole numbers, either positive or negative.
Floats are decimal numbers.
Complex numbers are numbers with a real and imaginary part, where j represents the imaginary unit.
Booleans have two built-in values: True or False.
Sequence types include strings, lists, and tuples.
Strings are arrays of bytes representing Unicode characters and can be enclosed in single quotes, double quotes, or triple quotes. Triple quotes are used for multi-line strings. Strings can be indexed to access specific characters.
Lists store multiple values and are changeable (mutable). Lists are defined using square brackets []. Lists can contain different data types. Items can be added to the end of a list using .append(). Items in a list can be changed by referring to the index number. Lists can be nested.
Tuples are similar to lists but are immutable, meaning they cannot be modified after creation. Tuples are defined using parentheses ().
Sets are unordered collections of unique elements. Sets do not allow duplicate elements. Sets are defined using curly brackets {}.
Dictionaries store key-value pairs. Dictionaries are defined using curly brackets {}, with each key-value pair separated by a colon :. Dictionary values are accessed using the key. Dictionary items can be updated, and key-value pairs can be deleted.
Operators:
Comparison operators compare two values.
== (equal to)
!= (not equal to)
> (greater than)
< (less than)
>= (greater than or equal to)
<= (less than or equal to)
Logical operators combine conditional statements.
and (returns True if both statements are true)
or (returns True if one of the statements is true)
not (reverses the result, returns False if the result is true)
Membership operators test if a sequence is present in an object.
in (returns True if a sequence is present in the object)
not in (returns True if a sequence is not present in the object)
Control Flow:
If statements execute a block of code if a condition is true.
if condition: (body of code)
else: (body of code) – executes if the initial if condition is false
elif condition: (body of code) – checks an additional condition if the initial if condition is false
Nested if statements can be used for more complex logic.
For loops iterate over a sequence (list, tuple, string, etc.).
for variable in sequence: (body of code)
Nested for loops can be used to iterate over multiple sequences.
While loops execute a block of code as long as a condition is true.
while condition: (body of code)
break statement: stops the loop even if the while condition is true
continue statement: rejects all the remaining statements in the current iteration of the loop
else statement: runs a block of code when the condition is no longer true
Functions:
Are blocks of code that run when called.
Defined using the def keyword.
Arguments can be passed to functions.
Arbitrary arguments allow an unspecified number of arguments to be passed.
Keyword arguments allow arguments to be passed with a key-value assignment.
Arbitrary keyword arguments allow an unspecified number of keyword arguments to be passed.
Web Scraping:
Involves extracting data from websites using libraries like Beautiful Soup and requests.
The requests library is used to send HTTP requests to a website.
Beautiful Soup is used to parse HTML content.
find() and find_all() methods are used to locate specific HTML elements.
Python Variable Assignment: A Comprehensive Guide
Variable assignment in Python involves using variables as containers for storing data values. You can assign a value to a variable using the equal sign (=). For example, x = 22 assigns the value 22 to the variable x. You can display the value of a variable using the print() function, such as print(x).
Key aspects of variable assignment:
Data Type Assignment: Python automatically assigns a data type to a variable based on the assigned value. For example, assigning 22 to x makes it an integer.
Overwriting: Variables can be overwritten with new values.
y = “mint chocolate chip”
print(y) # Output: mint chocolate chip
y = “chocolate”
print(y) # Output: chocolate
Case Sensitivity: Variables are case-sensitive. Y and y are treated as different variables.
Y = “mint chocolate chip”
y = “chocolate”
print(Y) # Output: mint chocolate chip
print(y) # Output: chocolate
Multiple Assignments: Multiple values can be assigned to multiple variables. For example:
x, y, z = “chocolate”, “vanilla”, “rocky road”
print(x) # Output: chocolate
print(y) # Output: vanilla
print(z) # Output: rocky road
One Value to Multiple Variables: Multiple variables can be assigned the same value. For example:
x = y = z = “root beer float”
print(x) # Output: root beer float
print(y) # Output: root beer float
print(z) # Output: root beer float
Combining Variables in Print: Variables can be combined within a print statement using the + operator for strings or commas to combine different data types. However, it is important to note that you can only concatenate a string with another string, not with an integer, unless you are separating the values by a comma in the print statement.
x = “ice cream”
y = “is”
z = “my favorite”
print(x + ” ” + y + ” ” + z) # Output: ice cream is my favorite
x = 1
y = 2
z = 3
print(x, y, z) # Output: 1 2 3
It is allowable to assign lists, dictionaries, tuples, and sets to variables as well.
Python Data Types: Numeric, Boolean, Sequence, Set, and Dictionary
Data types are classifications of the data that is stored; they inform what operations can be performed on the data. The main data types within Python include numeric, sequence type, set, Boolean, and dictionary.
Numeric data types include integers, float, and complex numbers.
An integer is a whole number, whether positive or negative.
A float is a decimal number.
A complex number is used for imaginary numbers, with j as the imaginary number.
Boolean data types only have two built-in values: either true or false.
Sequence type data types include strings, lists, and tuples.
Strings are arrays of bytes representing Unicode characters. Strings can be in single quotes, double quotes, or triple quotes. Triple quotes are called multi-line. Strings can be indexed, with the index starting at zero.
Lists store multiple values and are changeable. A list is indexed just like a string. A bracket means that it will be a list. Lists can have any data type within them. The comma in a list denotes that the values are separate. Lists can be nested.
Tuples are quite similar to lists but the biggest difference is that a tuple is immutable, meaning that it cannot be modified or changed after it is created. Typically, tuples are used when data is never going to change.
A set is similar to a list and a tuple, but does not have any duplicate elements. The values within a set cannot be accessed using an index, because it does not have one.
A dictionary is different than the other data types because it has a key value pair.
Web Scraping with Beautiful Soup and Requests
Web scraping involves extracting data from websites using libraries like Beautiful Soup and requests.
Key points regarding web scraping:
Libraries:
Requests: Used to send HTTP requests to a website to retrieve its HTML content. The requests.get() function sends a GET request to the specified URL and returns a response object. A response of 200 indicates a successful request.
Beautiful Soup: Used to parse HTML content, making it easy to navigate and search for specific elements.
Send a GET request to the URL and retrieve the page content:
page = requests.get(URL)
Create a Beautiful Soup object to parse the HTML content:
soup = Beautiful Soup(page.text, ‘html.parser’)
HTML Structure:
HTML (Hypertext Markup Language) is used to describe the structure of web pages.
HTML consists of elements defined by tags (e.g., <html>, <head>, <body>, <p>, <a>).
Tags can have attributes, such as class, id, and href.
Inspecting web pages using browser developer tools helps identify the relevant HTML elements for scraping.
Finding Elements:
find(): Locates the first occurrence of a specific HTML element.
find_all(): Locates all occurrences of a specific HTML element and returns them as a list.
Elements can be filtered by tag name, class, id, or other attributes.
soup.find_all(‘div’, class_=’container’)
Extracting Data:
.text: Extracts the text content from an HTML element.
.strip(): Removes leading and trailing whitespace from a string.
Workflow:
Import libraries: Import Beautiful Soup and requests.
Get the HTML: Use requests to fetch the HTML content from the URL.
Parse the HTML: Create a Beautiful Soup object to parse the HTML.
Find elements: Use find() or find_all() to locate the desired elements.
Extract data: Use .text to extract the text content from the elements.
Organize data: Store the extracted data in a structured format, such as a list or a Pandas DataFrame.
Pandas DataFrames and Exporting to CSV:
The extracted data can be organized into a Pandas DataFrame for further analysis and manipulation.
The DataFrame can be exported to a CSV file using df.to_csv(). To prevent the index from being included in the CSV, use index=False.
Learn Python in Under 3 Hours | Variables, For Loops, Web Scraping + Full Project
The Original Text
what’s going on everybody welcome back to another video today we’re going to be learning the basics of python in under 3 [Music] hours python is a fantastic skill to know how to do but I remember when I was first learning python it was a little bit intimidating it a little bit more difficult than I was used to when I had just known Excel and SQL and python seemed really really difficult but I’ve been using python for over 7even years now is a fantastic skill to know how to use so in this really long lesson we’re going to be walking through every you need to know in order to get started in Python I’ll be walking you through how to set up your environment to make sure that you can actually run your code and then we’ll be walking through all of the basics all the variables and for loops and while loops and even web scraping and we’ll even have a full project in this as well so we have a ton of things to cover and I hope it is really helpful without further Ado let’s jump onto my screen and get started all right so let’s get started by downloading anaconda anaconda is an open source distribution of python and our products So within Anaconda is our jupyter notebooks as well as a lot of other things but we’re going to be using it for our Jupiter notebooks so let’s go right down here and if I hit download it’s going to download for me because I’m on Windows but if you want additional installers if you’re running on Mac or Linux then you can get those all right here now if you are running on Windows just make sure to check your system to see if it’s a 32-bit or a 64 you can go into your about and your system settings to find that information I’m going to click on this 64-bit it’s going to pop up on my screen right here and I’m going to click save now it’s going to start downloading it it says it could take a little while but honestly it’s going to take probably about two to three minutes and then we’ll get going now that it’s done I’m just going to click on it and it’s going to pull up this window right here we are just going to click next because we want to install it this is our license agreement you can read through this if you would like I will not I’m just going to click I agree now we can select our installation type and you can either select it for just me or if you have multiple admin or users on one laptop you can do that as as well for me it’s just me so I’m going to use this one as it recommends now it’s going to show you where it’s installing it on your computer this is the actual file path it’s going to take about 3.5 gigs of space I have plenty of space but make sure you have enough space and then once you do you can come right over here to next and now we can do some Advanced options we can add Anaconda 3 to my path environment variable and when you’re using python you typically have a default path with whatever python IG or notebook that you’re using I use a lot of Visual Studio code so if I do this I’m worried it might mess something up so I am not going to do this it also says it doesn’t recommend it again messing with these paths is kind of something that you might want to do once you know more about python so I don’t really recommend you having this checked we can also register in AA 3 as my default python 3.9 you can do this one and I’m going to keep it this way just so I have the exact same settings as you do so let’s go ahead and click install install and now it is going to actually install this on your computer now once that’s complete we can hit next and now we’re going to hit next again and finally we’re going to hit finish but if you want to you can have this tutorial and this getting started with anonda I don’t want either of them because I don’t need them but if you would like to have those keep those checked and you can get those let’s click finish now let’s go down and we’re going to search for Anaconda and it’ll say Anaconda navigate and we’re going to click on that and it should open up for us so this is what you should be seeing on your screen this is the Anaconda Navigator and this is where that distribution of python and R is going to be so we have a lot of different options in here and some of them may look familiar we have things like Visual Studio code spider our studio and then right up here we have our Jupiter notebooks and this is what we’re going to be using throughout our tutorials so let’s go ahead and click on launch and this is what should kind of pop up on your screen now I’ve been using this a lot um so I have a ton of notebooks and files in here but if you are just now seeing this it might be completely blank or just have some you know default folders in here but this is where we’re going to open up a new jupyter notebook where we can write code and all the things that we’re going to be learning in future tutorials and you can use this area to save things and create folders and organize everything if you already have some notebooks from previous projects or something you can upload them here but what we’re going to do is go right to this new we’re going to click on the drop down and we’re going to open up a Python 3 kernel and so we’re going to open this up right here now right here is where we’re going to be spending 99% of our time in future videos this is where we’re going to write all of our code so right here is a cell and this is where we can type things so I can say print I can do the famous hello world and then I’ll run that by clicking shift enter and this is where all of our code is going to go these are called cells so each one of these are a cell and we have a ton of stuff up here and I’m going to get to that in just a second one thing I want to show you is that you don’t only have to write code here you can also do something called markdown and so markdown is its own kind of you could say language but um it’s just a different way of writing especially within a notebook so all we’re going to do is do this little hashtag and actually I think it’s a pound sign but I’m going to call it hashtag we’re going to do that and we’re going to say first notebook and then if I run that we have our first notebook and we can make little comments and little notes like that that don’t actually run any code they just kind of organize things for us and I’m going to do that in a lot of our future videos so just wanted to show you how to do that now let’s look right up here a lot of these things are pretty important uh one of the first things that’s really important is actually saving this so let’s say we wanted to change the title to I’m going to do a AA because I want it to be at the beginning um so I can show you this I’m do AAA new notebook and I’m going to rename it and then I’m going to save that so if I go right back over here you can see AAA new notebook that green means that it’s currently running and when I say running I mean right up here and if we wanted to we go ahead and shut that down which means it wouldn’t run the code anymore and then we’d have to run up a new cluster uh so let’s go ahead and do that I didn’t plan on doing that but let’s do it so we have no notebooks running and right here it says we have a dead kernel so this was our Python 3 kernel and now since I stopped it it’s no longer processing anything so let’s go ahead and say try restarting now and it says kernel is ready so it’s back up and running and we’re good to go the next thing is this button right here now this is an insert cell below so if I have a lot of code I know I’m going to be writing I can click a lot of that and I often do that because I just don’t like having to do that all the time so I make a bunch of cells just so I can use them you can also delete cells so say we have some code here we’ll say here and we have code here and then we have this empty cell right here we can just get rid of that by doing this cut selected cells we can also copy selected cells so if I hit copy selected cells then I can go right here and say paste selected cells and as you can see it pasted that exact same cell you can also move this up and down so I can actually take this one and say I wanted it in this location I can take this cell and move it up or I can move it down and that’s just an easy way to kind of organize it in instead of having to like copy this and moving it right down here and pasting it you can just take this cell and move it up which is really nice now earlier when I ran this code right here I hit shift enter you can also run and it’ll run the cell below so you can hit run and it works properly if you’re running a script and it’s taking forever and it’s not working properly at least it’s you don’t think it’s working properly you can stop that by doing this interrupt the kernel right here and anything you’re trying to do within this kernel if it’s just not working properly it’ll stop it you can restart it then you can try fixing your code you can also hit this button if you want to restart your kernel and this button if you want to restart the kernel and then rerun the entire notebook as we talked about just a second ago we have our code and our markdown code we’re not going to talk about either of these because we’re not going to use that throughout the entire series the next thing I want to show you is right up here if you open this file we can create a new notebook we can open an existing notebook we can copy it save it rename it all that good stuff we can also edit it so a lot of these things that we were talking about you can cut the cells and copy the cells using these shortcuts if you would like to we also go to view and you can toggle a lot of these things if you would like to which just means it’ll show it or not show it depending on what you want so if we toggle this toolbar it’ll take away the toolbar for us or if we go back and we toggle the toolbar we can bring it back we can also insert a few different things like inserting a cell above or a cell below so instead of saying This plus button you can just say A or B adding above or below we also have the cell in which we can run our cells or run all of them or all above or all below and then we have our kernels right here which we were talking about earlier where we can interrupt it and restart those there are widgets we’re not going to be looking at any widgets in this series but if it’s something you’re interested in you can definitely do that then we have help so if you are looking for some help on any of these things especially some of these references which are really nice you can use those and you can also edit your own keyboard shortcuts and now that we walked through all of that you now have anacon and jupyter notebooks installed on your computer in future videos this is where we’re going to be writing all of our python code so be sure to check those out so we can learn python together hello everybody today we’re going to be learning about variables in Python a variable is basically just a container for storing data values so you’ll take a value like a number or a string you can assign it to a variable and then the variable will carry and contain whatever you put into it so for example let’s go right over here we’re going to say x and this is going to be our variable we’re going to say is equal to now we can assign the value to it so let’s say I want to put 22 x is now equal to 22 so we won’t have to write out the number 22 in later scripts that we write we can just say x because X is equal to 22 it now contains that number so now we can hit enter and say print we do an open parentheses and we’ll say x now I’m going to hit shift enter and now it prints out that 22 because we are printing x and x is equal to 22 this is our value and this is our variable one really great thing about variables is that it assigns its own data type it’s going to automatically do this so we didn’t have to go and tell X that it’s an integer it just automatically knew that 22 is a number so we can check that by saying type and then open parenthesis and writing X and we’ll do shift enter again and this says that X is an integer type now we only assigned a integer to X let’s try assigning a string value or some text to a variable so we’ll say Y is equal to uh let’s say mint chocolate chip I’m feeling some ice cream today so we’ll say mint chocolate chip now if we print that again we’ll do print open parentheses Y and do shift enter it’ll print mint chocolate chip and if we look at the type we can see that the type is a string this time and not an integer now again we did not tell it that X was an integer and Y was a string it just automatically knew this let’s go up here really quickly we’re going to add several rows in here because we’re about to write a lot of different variables and really learn in- depth how to use variables the next thing to know about variables is that you can overwrite previous variables right now we have mint chocolate chip and that is assigned to the variable y so if I go down here I say print y I hit shift enter it’s going to print out mint chocolate chip but if I go right above it I say Y is equal to and let’s say chocolate if I print that out it’s now going to say chocolate whereas up here I’m reassigning it to Y it’s still going to say mint chocolate chip so if I come right down here and I copy this and I’m going to paste this right here initially it is going to assign y to Chocolate but then right here it will automat Ally overwrite y as mint chocolate chip and when we hit shift enter it’s going to show mint chocolate chip variables are also case sensitive so if I come up here and I say a capital Y this is a lowercase Y and this is a capital Y it is going to print out the correct one instead of mint chocolate chip and then if I go down here to the print and I type the capital Y it will give us the mint chocolate chip up till now we’ve only assigned one value to one variable but but we can actually assign multiple values to multiple variables so let’s do X comma y comma Z is equal to and now we can assign multiple values to all of those so we can say chocolate and then we’ll do a comma oops a comma then we can say vanilla and then we’ll do another comma and we’ll say rocky road now now this is going to assign chocolate to X vanilla to Y and Rocky Road to Z so what we can do is we’ll say print and we’ll go print print print and we’ll say X Y and Z so it prints out chocolate vanilla and rocky road and these are our three different values we can also assign multiple variables to one value and we can do this by saying X is equal to Y is equal to Z is equal to and we can put whatever we would like let’s do root beer float then we’ll come back up here we’ll copy this and let’s print off our X our Y and Z and they are all the exact same now so far we’ve really only looked at integers and strings but you can assign things like lists dictionaries tupal and sets all to variables as well so let’s go right down here so let’s create our very first list I’m going to say ice _ cream is equal to and that is our variable right there the ice uncore cream is our variable so now we’re going to do an Open Bracket like this and we’re going to come up here and copy all of these values and we’re going to stick it within our list so now within ice cream we have three string values chocolate vanilla and rocky road all within this list so what we can do is we can say x comma y comma Z is equal to to ice cream so now these three values chocolate vanilla and rocky road will be assigned to these three variables X Y and Z and we can copy this print up here and we’ll hit shift enter and now the X Y and Z all were assigned these values of chocolate vanilla and rocky road now something that we just did which is really important or something that you really need to consider is how you name your variables so right here we have ice cream now this to me is exactly how I usually write my variables but there are many different ways that you can write your variables so let’s take a look at that really quickly and let’s add just a few more because I have a feeling we’re going to go a little bit longer than what we have so there are a few best practices for naming variables first I’m going to show you kind of what a lot of people will do I’ll show you some good practices and I’m going to show you some bad practices as well that you should avoid doing the first thing that we’re going to look at is something called camel case and let’s say we want to name it test variable case oops case now if we have a test variable case the camel case is going to look like this we’ll have lowercase test and then we’ll have uppercase variable and uppercase case is equal to this is what this variable is going to look like and we can assign it a nilla swirl and this is what your camel case will look like it’s going to be lowercase and then all the rest of those uh compound words or however you want to say that these letters are going to be capitalized to kind of separate where the words end and begin let’s go right down here we’re going to copy this the next one is called Pascal case so Pascal case is going to look just a little bit different instead of the lower case at test it’s going to be a capital T in test so test variable case again this is a very similar way of writing it very similar to camel case but just a capital at the beginning now let’s look at the last one and this one is my personal favorite this one is going to be the snake case now this one is quite a bit different in the fact that you don’t use any capital letters and you separate everything using underscore so we’re going to write testore variable uncore case now typically let me have them all in there typically these are the best practices these are what you typically want to do but probably the best one to use is this snake case right here what a lot of people say is that it improves readability if you take a look at either the camel case or the Pascal case which you will see people do it’s not as easy to distinguish exactly what it says and the name of a variable is important because you can gain information from it if people name them appropriately so when I’m naming variables I usually write it in snake case because I just find it a lot easier to read because each word is broken up by this underscore so now let’s look at some good variable names these are all ones that you can use or could use so let’s do something like test VAR so test VAR is completely appropriate we can also do something like testore VAR oops underscore we could do underscore testore VAR you’ll see that often as well well people will start it with an underscore you can do test VAR capital T oops capital T capital V in test VAR or you could even do something like test VAR two now adding a number to your variable is not inherently a Bad Thing usually it’s semif frowned upon but there are definitely some use cases where you can use it but one thing that you cannot do is do something like putting the two at the front if you put the two at the front it no longer works it won’t run properly at all so we’re going to take that out so we can’t do that so I’m going to use this as an example of what you should not do you also can’t use a dash so something like test- var2 that doesn’t work either and you also can’t use something like a space or a comma or really any kind of symbol like a period or a backslash or equal sign none of those things will work work within your variable now another thing that you can do within your variable is use the plus sign so let’s assign this we’ll say x is equal to and we’ll do a string we’ll say ice cream is my favorite and then we’ll do a plus sign and we’ll say period now what this will do is it will literally add these two strings together so let’s do print and we’ll do X so now it says ice cream is my favorite one thing that we cannot do in a variable is we cannot add a string and a number or an integer so we can’t do ice cream as my favorite two if we try to do that it will give us this error right here so in this error it’s saying you can only concatenate a string not an integer to a string so only a string plus a string for this example you can also do and we’ll say x is equal to or we’ll say y we’ll say Y is equal to 3 + 2 and it should output 5 because you can also do an integer and an integer now so far we’ve only been outputting one variable in the print statement but you can actually add multiple variables within a print statement so let’s go right down here we’re going to say let’s give it some more right there so we’ll say x is equal to ice cream and we’ll say Y is equal to is and then the last one Z is equal to my favorite and we’ll do a period at the end now we can go to the bottom and we can say print x + y + C and when we enter that and when we run and when we run that we get ice cream is my favorite now we can actually add a space before is a space before my and when we hit shift enter it says ice cream is my favorite you can also do this exact same thing with numbers as well so we’ll say x = to 1 2 and what Z is equal to 3 so this should equal six now one thing that we tried to do was assign to one variable a string plus an integer and that did not work but what you can do is you can take something like this and you can say ice cream and we’ll get rid of this one and we’ll get rid of the Z Now say Plus is actually not going to work let’s try running this so again we can’t concatenate these but what we can do in the print statement is we can separate it by a comma so when we add this comma it should work properly let’s hit enter and it says ice cream 2 again this makes no sense but you are able to combine a string and an integer separating by a comma now this is the meat and potatoes of variables there are some other things as well but some of those things are a little bit more advanced and not something I wanted to cover in this tutorial although we may be looking at some of those things in future tutorials but this is definitely the basics what you really really need to know about variables hello everybody today we’re going to be talking about data types in Python data types are the classification of the data that you are storing these classifications tell you what operations can be performed on your data we’re going to be looking at the main data types within python including numeric sequence type set Boolean and dictionary so let’s get started actually writing some of this out and first let’s look at numeric there are three different types of numeric data types we have integers float and complex numbers let’s take a look at integers an integer is basically just a whole number whether it’s positive or negative so an integer could be a 12 and we can check that by saying type we’ll do an open parenthesis and a Clos parenthesis and if we say the type of 12 it’s going to give us an integer or if we say a -2 that is also an integer we can also perform basic calculations like -2 + 100 and that’ll tell us it is also an integer so whether it’s just a static value or you’re performing an operation on it it’s still going to be that data type if those numbers are whole numbers whether negative or positive now let’s take this exact one and let’s say 12 and we’ll do plus 10.25 when we run this it’s no longer going to be a whole number it’ll now be a float so let’s check this now this is a float type because is no longer a whole number it’s now a decimal number and the last data type within the numeric data type is called complex let’s copy this right down here now personally this is not one that I’ve used almost ever but it is one just worth noting so you can do 12 plus and let’s say 3 J and if we do this it’s going to give us a complex the complex data type is used for imaginary numbers for me it’s not often used but if you do use it J is used as that imaginary number if you use something like C or any other number it’s going to give you an error J is the only one that will work with it now let’s take a look at Boolean values so we’ll say Boolean the Boolean data type only has two built-in values either true or false so let’s go right down here and say type true and when we run this it’ll say bu which stands for Boolean we can do the exact same thing with false that is also Boolean and this can be used with something like a comparison operator so let’s say 1 is greater than 5 and let’s check this this is giving us a Boolean because it’s telling us whether one is greater than five let’s bring that right down here this will give us a false so it’s telling us that one is not greater than five and just as we got a false we can say 1 is equal to 1 and this should give us a true so now let’s take a look at our sequence type data types and that includes strings lists and tupal we let’s start off by looking at string strings in Python strings are arrays of byes representing Unicode characters when you’re using strings you put them either in a single quote a double quote or a triple quote I call them apostrophes it’s just what I was raised to call them but most people who use Python call them quotes So Right Here we have a single quote and that works well we can do a double quote and that works also and as you can see they are the exact same output and then we have a triple quote just like this and this is called a multi-line so we can write on multiple lines here so let’s write a nice little poem so we’ll say the ice cream vanquished my longing for sweets upon this diet I look away it no longer exists on this day and then if we run that it’s going to look a little bit weird it’s basically giving us the raw text which is completely fine but let’s let’s call this a multi-line and we’re going to call this a variable multi-line and we’re going to come down here and say print and before I run this I have to make sure that this is Ran So now let’s print out our multi-line and now we have our nice little poem right down here now something to know about these single and double quotes is how they’re actually used so if we use a single quote and we say I’ve always wanted to eat a gallon of ice cream and then we do an apostrophe at the end obviously something went wrong here what went wrong is when you use a single quote and then within your text within your sentence you have another apostrophe it’s going to give you an error so what we want to do is whenever we have a quote within it we need to use a double quote these double quotes will negate any single quotes that you have within your statement they won’t however negate another double quote so you need to make sure you aren’t using double quotes within your sentence if you want to do something like that you need to use the triple quotes like we did above so we can do double double and then let’s paste this within it and anything you do Within These triple quotes will be completely fine as long as you don’t do triple quotes within your triple quotes we’ll say this is wrong so even though it’s between these two triple quotes it doesn’t work exactly again you just have to understand how that works you have to use the proper apostrophes or quotes within your string and just to check this we can always say here’s our multi-line we can always say type of multi-line and that is still a string one really important thing to know about strings is that they can be indexed indexing means that you can search within it and that index starts at zero so let’s go ahead and create a variable and we’ll just say a is equal to and let’s let’s do the all poopular hello world let’s run this and now when we print the string we can say a and we’re going to do a bracket and now we can search throughout our string using the index so all you have to do is do a colon we going say five what this is going to do is is going to say zero position zero all the way up to five which should give us the whole hello I believe let’s run this and it’s giving us the first five positions of this string we can also get rid of the colon and just say something like five and then when we run this it’s actually going to give us position five so this is 0 1 2 3 4 and then five is the space let’s do six so we can see the actual letter and that is our w we can also use a negative when we’re indexing through our string so we could say -3 and it’ll give us the L because it’s -1 2 and three we can also specify a range if we don’t want to use the default of Z so before we did 0 to 5 and it started at zero because that was our default but we could also do 2 to 5 let’s run this and now we go position 0 1 and then we start at 2 L L O now we can also multiply strings and we have this a hello world so we can do a time three and if we run this it’ll give us hello world three times and we can also do A+ a and that is hello world hello world now let’s go down here and take a look at lists lists are really fantastic because they store multiple values the string was stored as one value multiple characters but a list can store multiple separate values so let’s create our very first list we’ll say list really quickly and then we’ll put a bracket and a bracket means this is going to be a list there are other ones like a squiggly bracket and a parentheses these denote that they are different types of data types the bracket is what makes a list a list so to keep it super simple we’ll say 1 2 3 and we’ll run this and now we have a list that has three separate values in it the comma in our list denotes that they are separate values and a list is indexed just like a string is indexed so position zero is this one position one is the two and position two is the three now when we made this list we didn’t have to use any quotes because these are numbers but if we wanted to create a list and we wanted to add string values we have to do it with our quotes so we’ll say quote cookie dough then we’ll do a comma to separate the value and then we’ll say strawberry and then we’ll do one more and this will just be chocolate and when we run this we have all three of these values stored in our list now one of the best things about list is you can have any data type within them they don’t just have to be numbers or strings you can basically put anything you want in there so let’s create a new list and let’s say vanilla and then we’ll do three and then we’ll add a list within a list and we’ll say Scoops comma spoon and then we’ll get out of that list and then we’ll add another value of true for Boolean and now we can hit shift enter and we just created a list with several different data types within one list now let’s take this one list right here with all of our different ice cream flavors we’ll say icore cream is equal to this list now one thing that’s really great about lists is that they are changeable that means we can change the data in here we can also add and remove items from the list after we’ve already created it so let’s go and take ice cream and we’ll say ice cream. append and this is going to append it to the very end of the list we do an open parenthesis let’s say salted caramel now when we run this and we call it just like this it’s going to take this list add salted caramel to the end and we’ll print it off and as you can see it was added to the list and just like I said before let me go down here we can also change things from this list so let’s say ice cream and then we need to look at the indexed position so we’re going to say zero and that’s going to be this cookie dough right here we can say that is equal to so we can now change that value so let’s call that butter peon and now when we call it we can now see that the cookie dough was changed to butter peon another thing that you saw just a little bit ago is something called a list within a list basically a nested list so we had Scoops spoon true let’s give this and we’ll say nested uncore list is equal to now when we run this we now have this nested list so if we look at the index and we say 0 we’ll get vanilla if we say two we’ll get scoops and spoons now since we have a list within a list we can also look at the index of that nested list so let’s now say one and that should give us just spoon and you can go on and on and on with this you can do lists within lists within lists and all of them will have indexing that you can call now let’s go down here and start taking a look at tupal so a list and a tupal are actually quite similar but the biggest difference between a list in a tupal is that a tupal is something called immutable it means it cannot be modified or changed after it’s created let’s go right up here we’re going to say Tuple and let’s write our very first tupal so we’ll say Tuple undor Scoops is equal to and then we’ll do an open parenthesis now these open parentheses you’ve seen if you do like a print statement but that’s different because that’s executing a function this is actually creating a tupal which is going to store data for us so we’ll say one 2 three two and one let’s go ahead and create that tupal and we can just check the data type really quickly and it’s a tupal and just like we saw before a tupal is also indexed so if we go at the very first position which is a one we will get the output of a one but we can’t do something like aend and then add a value like three if we do that it’s going to say tupal object has no attribute aend it’s just because you cannot change or add anything to a tupal just like we were talking about before typically people will use tupal for when data is never going to change an example for this might be something like a city name a country a location something that won’t change they definitely have their use cases but I don’t think they’re as popular as just using a list so now let’s scroll down and start taking a look at sets but really quickly let me add a few more cells for us and let’s say sets now a set is somewhat similar to a list and a tupal but they are little bit different in the fact that they don’t have any duplicate elements another big difference is that the values within a set cannot be accessed using an index because it doesn’t have an index because it’s actually unordered we can still Loop through the items in a set with something like a for Loop but we can’t access it using the bracket and then accessing its index point so let’s go ahead and create our very first first set so we’re going to say daily pints then we’re going to say equal to and to create a set we’re going to use these squiggly brackets I don’t know if there’s an actual name for those if I’m being honest I call them squiggly brackets and that’s what we’re going to go with we’re going to put in a one a two and a three so let’s go ahead and run this and let’s look at the type and as you can see it is a set now when we print this out it’s going to show us one a two and a three and those are all the values Within set but if we copy this and we’ll say daily pant log this is going to be every single day maybe I had different values now when we run this and we do the exact same thing now when we print this it’s going to have just the unique values within that set now a use case for set and this is something that I’ve done in the past is comparing two separate sets maybe you have a list or a tupal and you convert that into a set and that will narrow it down down to its unique values then you can compare the unique values of one set to the unique values in another set and then we can see what’s the same and what’s different so let’s go down here and let’s say wife’s uncore daily and we’ll just copy this right here we’ll say is equal to let’s do our squiggly lines let’s do one two let’s do just random numbers so now this is my daily log and this is my wife’s daily log and now we can compare these values so let’s go right down here let’s say print we’ll do my daily logs and then we’ll do this bar right here and this is going to show us the combined unique values it’s basically like putting them all in one set and then trimming it down to just the unique values so we’ll take wife’s daily pintes log and when we run this we actually need to run this first when we run this we should see all the unique values between these two sets and so as you can see 0 1 2 3 4 5 6 7 24 31 so these are all the unique values between these two sets we can also do another one and instead of this bar we’re going to do this symbol right here which I believe is called an Amper sand don’t quote me on that but when we run this it’s going to show what matches that means which ones show up in both sets so the only ones that show up in both sets are 1 2 3 and five we can also do the opposite of that by doing a minus sign and this is going to show us what doesn’t match and so we have 4 6 and 31 now where is our 24 that was in our wife’s daily pints log it’s in this one but we’re subtracting the values on this one so let’s reverse this and we’ll say daily pints log and let’s run it now those are our other values so we’re taking the values of this and then we’re subtracting all the ones that are the same and getting the remaining values and then for our last one we can get rid of this and we’ll do this symbol right here and this is going to show if a value is either in one or the other but not in both so let’s run this so these values are completely unique only to each of those sets now the very last one that we’re going to look at in this video is dictionaries so let’s go right down here let’s add a few cells and let’s say dictionaries now I saved dictionary for last because this one is probably the most different out of all the previous data types that we’ve looked at within a data type we have something called a key value pair that means when we use a dictionary it’s not like a list where you just have a value comma value comma value we have a key that indicates what that value is attributed to so let’s write out a dictionary to see how this looks so we’re going to say dictionary cream and just like a set we use a squiggly line but the thing that differentiates it is that in a dictionary we’ll have that key value pair whereas in a set each value is just separated by a comma so let’s write name and this is our key and then we do a colon and this is then where we input our value so we’re going to say Alex freeberg and then we separate that key value Pair by a comma and now we can do another key value pair so we’ll say weekly intake and and a colon and we’ll say five pints of ice cream do a comma and then we’ll do favorite ice creams and now what we’re going to do is we’re going to put in here a list so within this dictionary we can also add a list we’ll do MCC from mint chocolate chip and then we’ll add chocolate another one of my favorites so now we have our very first dictionary let’s copy this and run it and let’s just look at the type and as as you can see it says that this is a dictionary let’s also print it out now if we want to we can take our dictionary cream and say dot values with an open parenthesis and when we execute this we’ll see all of the values within this dictionary so here’s our values of Alex freeberg five mint chocolate chip and chocolate we can also say keys and when we run this all of the keys the name weekly intake and favorite ice creams and we can also say items so this key value pair is one item and this key value pair is another item now one difference between something like a list and a dictionary is how you call the index but you can’t call it by doing something like this where you just do a bracket oops and say zero so this would in theory take this very first one right our very first key value pair that’s going to give us an error how you call a dictionary is actually by the key so it doesn’t technically have an index but you can specify what you want to call and take it out so we’re going to say name and this is going to call that key right here and when we run this we’ll get the value which is Alex freeberg one other thing that you can do is you can also update information in a dictionary which we can’t with some other data types so for this for the name it was Alex freeberg now let’s say Steen freeberg and when we update that I’m also going to print the dictionary get rid of this so it’s going to update Christine freeberg in that value of the name so let’s go ahead and run this and now it changed the name from Alex freeberg to Christine freeberg we can also update all of these values at one time so let’s copy this and I’m going to put it right down here I’m going to say dictionary.c cream. update then we’re going to put a bracket or not a rocket but a parenthesis around these so now what we’re going to do is update this entire thing let me take this say print this dictionary now we can update this to anything we want so instead of here I can say I’ll say weight and because of all that ice cream I now weigh 300 lb so let’s run this and as you can see it did not delete our key value pair right here instead it just added to it when you’re using the update we can’t actually delete that’s the delete statement and I’ll show you that in just a second but all we did was added this new value it also is going to check and see if you changed anything with your key value pair so we can go in here and change this value and we’ll say 10 so now when we run this the value of this key value pair was changed but let’s say we do want to delete it we’ll say deel that stands for delete part of this dictionary cream and now let’s specify the key which will also delete the value with it but let’s specify the key that we want to get rid of and let’s say wait and then let’s print that again and as you can see the weight was deleted from that dictionary so hello everybody today we’re going to be taking a look at comparison logical and membership operators in Python operators are used to perform operations on variables and values for example you’re often going to want to compare two separate values to see if they are the same or if they’re different within Python and that’s where the comparison operator comes in right here you can see our operators you can also see what they do so this equal sign equal sign stands for equal we have the does not equal the greater than less than greater than or equal to and less than or equal to and honestly I use these almost every single time I use Python so these are very important to know and know how to use so let’s get rid of that really quickly and actually start writing it out and see how these comparison operators work in Python the very first one that we’re going to look at is equal to now you can’t just say 10 is equal to 10 let’s try running that really quickly by clicking shift enter it’s going to say cannot assign to literal that’s because this is like assigning a variable we’re trying to say 10 is equal to 10 and then we can call that 10 later but that’s not how this actually works what we’re trying to do is to determine whether 10 is equal to 10 so we’re going to say equal sign equal sign and then if we run that by clicking shift enter again it’s going to say true now if we put something else like 50 in there and we try to run this it’s going to say false so really what you’re going to get when you use these comparison operators is either a true or a false if we take this right down here we can also say does not equal and we’re going to use an exclamation point equal sign and that says 10 is not equal to 50 and that should be true you can also compare strings and variables so let’s go right down here and we’re going to say vanilla is not equal to chocolate and when we run this it’ll say false now if it was the same just just like when we did our numbers it should say true and we can also compare variables so we’ll say x is equal to vanilla and Y is equal to chocolate and then when we come down here we can say x is equal to Y and it’ll give us a false and we say X is not equal to Y and it’ll give us a true the next one that we’re going to take a look at is the less than so let’s copy this one right up here let’s scroll down and let’s say 10 is less than 50 now this will come out as true now let’s say we put a 10 in here before 10 was of course less than 50 but is 10 less than 10 no that’s false because they are the same so if we want an output that is true all we would have to add is an equal sign right here and this would say 10 is less than or it is equal to 10 and now it’s true of course we can say the exact same thing by saying greater than so 10 is equal or greater than 10 that’ll be true because 10 is equal to 10 we can also say 50 is greater or equal to 10 because 50 is obviously greater than 10 now let’s look at logical operators that are often combined with comparison operators so our operators are and or and not so if you have an and that returns true if both statements are true if it’s or only one of the statements has to be true and the not basically reverses the result so if it was going to return true it would return turn false I don’t use this not one a lot but I will show you how it works so let’s actually test that out so before we were saying 10 is greater than 50 and of course this returned false so now let’s add a parentheses around this 10 is greater than 50 and we’re going to say and we’ll do an open parenthesis 50 is greater than 10 now this statement right here is true 50 is greater than 10 so we have a true statement and a false statement but this and is going to look at both of them it’s going to say they both need to be true in order to return a true so let’s try running this and we still have a false if we want it to return true we’re going to have to change this to make it a true statement so 70 is greater than 50 and 50 is greater than 10 when we run this it should return true now let’s look at the or so let’s copy this and we’ll say 10 is greater than 50 or 50 is greater than 10 now this is a false statement and this is a true statement so if even one of them is a true statement the output should be true and again we can do this even with strings so we can do vanilla and chocolate there we go and vanilla is actually greater than chocolate because V is a higher number in the alphabetical order so V is like 20 something whereas chocolate is three right so it actually looks at the spelling for this so if we say or here it will come out true and if we say and here it should also be true because V is greater than C and 50 is greater than 10 so this should also be true now let’s copy this right here and we’re going to say not so what we had before is 50 is greater than 10 that returned true but now all we’re doing is putting not in front of it so instead of returning true it’s going to return false so now let’s take a look at membership operators and we use this to check if something whether it’s a value or a string or something like that is within another value or string or sequence our operators are in and not in so it’s pretty simple if it’s in it’s going to return true if the sequence with a specified value is present in the object just like we were talking about and for not in it’s basically the exact same thing if it’s not in that object so let’s start out by taking a look at a string we’re going to say icore cream is equal to I love chocolate ice cream and then we’re going to say love in icore cream and that will will turn true so all we’re doing is searching if the word love or that string is in this larger string we could also just do that by literally copying this and putting this where this is so we can check is this string part of this string and it’ll say true we can also make a list so we’ll say Scoops is equal to and then we’ll do a bracket and we’ll say 1 2 3 4 5 and then we’ll say two in Scoops so all we’re doing is searching to see if two is within this list and that should return true now if we put a six here and we said not in it will also return true because six is not in scoops and that is true and just like we did we could also say wanted underscore Scoops and we’ll say eight so I wanted eight Scoops so we can say wanted Scoops in Scoops and this should return true because there’s not an eight within the Scoops that we wanted and if we said in and we said we wanted eight is that within our list that we created and that’s going to return a false hello everybody today we’re going to be taking a look at the if statement within python now it’s actually the if lfl statement but that’s a mouthful so I’m just going to call it the if L statement now we have this flowchart and I apologize for being blurry but this is the absolute best one that I could find right up top we have our if condition now if this if condition is true we’re going to run a body of code but if that condition is false we’re going to go over here and go to the LF condition the LF condition or statement is basically saying if the first if statement doesn’t work let’s try this if statement if this LF statement is true it goes to this body of code if it’s false it’ll come over here to the else and the else is basically if all these things don’t work then run this body of code now you can have as many ill if statements as you want but you can only have one if statement and one else statement so let’s write out some code and see how this actually looks let’s first start off by writing if that is our if statement and now we have to write our condition which is about to be either met or not met so we’ll say if 25 is greater than 10 which is true we’ll say colon and then we’re going to hit enter and it’s going to automatically indent that line of code for us and this is our body of code so if 25 is greater than 10 our body of code will execute so for us we’re just going to write print and we’ll say it worked now if we run this it’s going to check is 25 greater than 10 if that is true print this so let’s hit shift enter and it worked now let’s take this exact code we’ll paste it right down here and we’ll say is less than and right now this if statement is not true so it’s not actually going to work as you can see there’s no output there’s nothing that happened really but it did check to see if 25 was less than 10 but it just wasn’t true now we can use our else statement so we’re going to come right down here and we’re going to say else and we’ll do a colon and we’ll hit enter again automatically indenting and we’re going to say print and we’re going to say it did not work dot dot dot so what it’s going to do is it’s going to come up here and check is 25 less than 10 no it’s not so this body of code is not going to be executed it’s going to go right down to this else statement now this else statement is going to be printed there’s no condition on this so the if statement has a condition 25 is less than 10 this has no condition so if this doesn’t work if this is false it’s going to come down here and it will run this body of code let’s run this by clicking shift enter and as you can see our output is it did not work now let’s go back up here and put greater than because this is now true it’s going to say if 25 is greater than 10 print it worked and then it’s going to stop it’s not going to go to this L statement at all so let’s run this and our output is it worked so what if we have a lot of different conditions that we want to try let’s come right down here this is where the LF comes in so really quickly let’s change this to a not true a false statement we’re going to go down and say LF and we’re going to say if it is and let’s say 30 we’ll say LF worked so now it’s going to check is 25 less than 10 no it’s not let’s look at the next condition is 25 less than 30 and if it is we’ll print L if worked so let’s try running this and L if worked now we can do as as many of these LF statements as we want we can do let’s just try a few of them right here so we’ll say if 25 is less than 20 is less than 21 and let’s do 40 and let’s do 50 so we’ll say LF lf2 lf3 and lf4 now if you look at this the first one that is actually going to work is this 25 to 40 right here once this one is checked and it comes out as true none of the other LF or L statements will work so let’s try this one it should be lf3 and this one ran properly now within our condition so far we’ve only used a comparison operator we can also use a logical operator like and or or so we can say if 25 is less than 10 which it’s not let’s say or actually and we’ll say or 1 is less than three which is true if we run this now it will actually work so we can use several different types of operators within our if statement to see if a condition is true or not or several conditions are true there’s also a way to write an if else statement in one line if you want to do that so we can write print we’ll say it worked and then we’ll come over here and say if 10 is greater than 30 and then we’ll write else print and we’ll say it did not work just like we had before except now it’s all occurring on one line so let’s just try this and see if it works so it’s saying print it worked if 10 is greater than 30 which it wasn’t so it went to the L statement and then it printed out our body right here although we didn’t have any indentation or multiple lines it was all done in one line now there’s one other thing that we haven’t looked at yet uh and I’m going to show it to you really quickly and that’s a nested if statement so when we run this it’s going to say it worked it works because it says 25 is less than 10 or 1 is less L than three since this is true it’s going to print out it worked but we can also do a nested if statement so we can do multiple if statements as well so we’re going to hit enter and we’ll say if and we’ll do a true statement here so we’ll say if 10 is greater than 5 let’s do a colon hit enter then we’ll say print and then we’ll type A String saying this nested if statement oops worked now let’s try this out and see what we get so it went through the first if statement it said it was true and it prints out it worked this is still the body of code so it goes down to this next if statement and it says if 10 is greater than five we’re going to print this out and you could do this on and on and on it can basically go on forever and you can create a really in-depth logic and that actually happens a lot when you start writing more advanced code hello everybody today we’re going to be learning about four Loops in Python the for Loop is used to iterate over a sequence which could be a list a tube an array a string or even a dictionary here’s the list that we’ll be working with throughout this video and I have this little diagram right here which kind of explains how a for Loop works the for Loop is going to start by looking at the very first item in our sequence or our list and that’s going to be our one right here it’s going to ask is this the last element in our list and it is not so it’s going to go down to this body of the for Loop now we can have a thousand different things that can happen in the body of the for loop as we’re about to look out in just second then it’s going to go up to the next element and ask is this the last element reached so it’ll be no again because we’ll be going to the two and then the three and then the four and the five once it reaches the five it’ll go to the body of the for Loop and then when it asks if that’s the last element the answer would be yes because it’s iterated through all the items within the list and then we would exit the loop and the for Loop would be over now that may not have made perfect sense but let’s actually start writing out the syntax of a for Loop so we can understand understand this better to start our for loop we’re going to say four and then we’re going to give it a temporary variable for this for Loop so it’s a variable as it iterates through these numbers it’s going to assign the variable to that number so for this one we’re just going to say number because it’s pretty appropriate because these are all numbers and then we’re going to say in integers now right here you can put just about anything this could be the list this could be a tuple this could be a string even but that is what we’re going to iterate through so we’re saying for the variables each of these numbers within this list of integers and then we’re going to write a colon this is the body of code that’s going to actually be executed when we run through and iterate through our list so for our first example we’re going to start off super simple and all we’re going to do is say print open parentheses and say number as it iterates through the one two 3 4 and five number becomes our variable that is going to be printed so during that first loop our one will be printed because that will be assigned right here then through the next iteration the two will be assigned and it’ll be put right here in each Loop until the very end so let’s hit shift enter and as you can see it did exactly that now in this body and I’ll copy and paste this down here in this body we really can do just about anything we want we don’t even have to use this variable number right here we can just print yep if we wanted to and and what it’s going to do is for each iteration all five of those every time it Loops through it’s going to print off yep so let’s hit shift enter and it printed it off for us so really we weren’t even using the numbers within the list we were really just using it as almost a counter now let’s copy this integers once again let’s go right up here and let’s go copy this for Loop that we wrote now we do not have to call this number this can be anything you want any variable name that you’d like to name it we could call it jelly and we can do jelly plus jelly I think you’re getting the picture right when it Loops through that one it’s doing one plus one when it Loops through the two it’s doing 2 + 2 that is basically how a for Loop works now for a dictionary it’s going to handle it a little bit differently so let’s create a dictionary really quickly so we’ll say ice cream d iary is equal to we’re going to do a squiggly brackets so we’re going to say name and we’re going to say colon we need to assign our value for that item so we’re going to say Alex freeberg we’ll do our next one separated by a comma and we’ll say weekly intake and I’ll say five Scoops per week the next one we will do is favorite ice creams and for this one we’re going to do something a little bit different for this we’re going to have a list list within this dictionary so we’ll say within our list of my favorite ice creams we’ll say mint chocolate chip and I’ll just do MCC for that and we’ll separate that out by a comma and we’ll say chocolate so now we have this dictionary ice cream dick and within it we have my name my weekly intake and my favorite ice creams with a list in there as well let’s hit shift enter and now we’re going to start writing our for Loop now the for Loop is going to look very similar but to call it dictionary it’s just a little bit different so we’re going to say for the cream in icore creamore dictionary. values and then we’re going to do parentheses and then a colon now we’re going to print the cream so in order to indicate what we actually want to pull we have to specify within the dictionary what we want are we pulling the item are we pulling the value we need to specify this so that’s why we have thist value right here so let’s run this and see what we get so as you can see we are pulling in the values right here that’s why we’re pulling in Alex freeberg 5 and mint chocolate chip SL chocolate now we are able to call both of those both the key and the value so let’s go right down here and we can do both the key and the value so we can pull two things at one time and we’re going to do this by saying do items so we could also do key if we just wanted to do a key but we want to do items so we going to do both of them so we’re going to go right down here and say four key and value in ice cream dictionary. items print and let’s write key and then we’ll do a comma and then let’s give it a little arrow or something like that uh something like this and then we’ll do a comma and we’ll say value and let’s print this off and see what we get so it’s looping through and for each key and value it’s saying here is the key so that’s the name then we have weekly intake then we have favorite ice creams it’s giving us a little arrow and then we’re also printing off the value so we have name Alex freeberg weekly intake five favorite ice creams mint chocolate chip and chocolate so now let’s talk about nested for Loops we’ve looked at for Loops we understand how they work and why they do what they do but what about a nested for Loop a for Loop within a for Loop for this example let’s create two separate lists let’s create flavors and let’s make that a list by making it a bracket and we’ll do vanilla the classic chocolate and then cookie dough all great flavors so that’s our first list and then we’re going to say toppings and we’ll do a bracket for that as well and we’ll say fudge and then we’ll do Oreos and then we’ll do Marsh mows is how you spell marshmallows I think it’s an e that looks wrong I might be spelling it wrong but that’s okay so let’s save this by clicking shift enter and now we have our flavors and our toppings so now let’s write our first for Loops we’re going to say 41 as in our number one for loop we’re going to say in flavors and we’ll do a colon we’ll click enter now we can write our second for Loop so we’re going to say 42 in toppings and then we’ll do a colon and enter and then we’re going to say print and we’ll do an open parenthesis and then we’re going to say one so we’re printing the one in flavors and then we’re going to say one comma we to say topped with comma two so what this is essentially going to do is we’re going to say for one we’re going to take the very first one in flavors and then we’re going to Loop through all of two as well so we’re going to Loop through hot fudge Oreos and marshmallows and once we print that off then we will Loop all the way back to Flavors and look at the next iteration or the next sequence within the first for Loop so let’s run this really quickly and see what we get so as you can see it goes vanilla vanilla vanilla and vanilla is topped with the hot fudge the Oreos and the marshmallows and then we start iterating through our second one in our first for Loop so there’s that hierarchy so we’re iterating completely through this one before we actually go to the very first for Loop and start iterating through that one again now that is essentially how a nested for Loop works these nested for Loops can get very complicated in fact for Loops in general can get very complicated the more you add to it and the more you’re wanting to do with it but that is basically how a for Loop and a nested for Loop Works hello everybody today we’re going to be taking a look at while Loops in Python the while loop in Python is used to iterate over a block of code as long as the test condition is true now the difference between a for Loop and a while loop is that a for Loop is going to iterate over the entire sequence regardless of a condition but the while loop is only going to iterate over that sequence as long as a specific condition is met once that condition is not met the code is going to stop and it’s not going to iterate through the rest of the sequence so if we take a look at this flowchart right here we’re going to enter this while loop and we have a test condition right here the first time that this test condition comes back false it’s going to exit the while loop so let’s start actually writing out the code and see how this while loop works so let’s create a variable we’re just going to say number is equal to one and then we’ll say while and now we need to write our condition that needs to be met in order for our block of code beneath this to run so we’re going to say while number is less than five and then we’ll do colon enter and now this is our block of code we’re going to say print and then we’ll say number now what we need to do is basically create a counter we’re going to say number equals number + 1 if you’ve never done something like this it’s kind of like a counter most people start it at zero in fact let’s start it at zero and then each time it runs through this while loop it’s going to add one to this number up here and then it’s going to become a one a two a three each time it iterates through this while loop now once this number is no longer less than five it’ll break out of the while loop and it will no longer run so let’s run this really quick by hitting shift enter so it starts at zero and it’s going to say while the number is less than five print number so the first time that it runs through it is zero and so it prints zero and then it adds one to number and then it continues that y Loop right here and it keeps looping through this portion it never goes back up here to this line of code this is just our variable that we start with and then once this condition is no longer met once it is false then it’s going to break out of that code now that we basically know how a y Loop Works let’s look at something called a break statement so let’s copy this right down here and what we’re going to say is if number is equal to three we’re going to break now with the break statement we can basically Stop the Loop even if the while condition is true so while this number is less than five it’s going to continue to Loop through but now we have this break statement so it’s going to say if the number equals three we’re going to break out of this while loop but if this is false we’re going to continue adding to that number just like normal so let’s execute this so as you can see it only went to three instead of four like before because each time it was running through this y while loop it was checking if the number was equal to three and once it got to three this became true and then we broke out of this while loop the next thing that I want to look at and we’ll copy this right down here is an else statement much like an if statement but we can use the else statement with a while loop which runs the block of code and when that condition is no longer true then it activates the else statement so we’ll go right down here and we’ll say else and we’ll do a colon and enter and then we’ll say print and we’ll say no no longer less than five now because this if statement is still in there it will break so let’s say six and then we’ll run this and so it’s going to iterate through this block of code and once this statement is no longer true once we break out of it we’re going to go to our else statement now as long as this statement is true it’s going to continue to iterate through but once this condition is not met then it will go to our L statement and we’ll run that line of code now the L statement is only going to trigger if the Y Loop no longer is true if we have something like this if statement that causes it to break out of the while loop the lse statement will no longer work so let’s say if the number is three and we run this the L statement is no longer going to trigger so this body of code will not be run now the next thing that I want to look at is the continue statement if the continue statement is triggered it basically rejects all remaining statements in the current iteration of the loop and then we’ll go to the next iteration now to demonstrate this I’m going to change this break into a continue so before when we had the break if the number was equal to three it would stop all the code completely but when we change this to continue which we’ll do right now what it’s going to do is it’s no longer going to run through any of the subsequent code in this block of code it’s just going to go straight up to the beginning and restart our while loop so what’s going to happen when we run this is it’s going to come to three it’s going to become three it’s going to continue back into the while loop but it’s never going to have that number changeed to be added to one to continue with the while loop this will create an infinite Loop let’s try this really quickly and as you can see it’s going to stay three forever eventually this would time out but I’m just going to stop the code really quick so if we just change up the order of which we’re doing things we’re going to say there and we’re going to put this down here so what it’s going to do now instead of printing the number immediately and then adding the number later we’re going to add the number right away and then we’re going to say if it is three we’re going to continue and it’s going to print the number so let’s try executing this and see what happens so as you can see we no longer have the three in our output what it did was when we got to the number three it continued and didn’t execute this right here which prints off that number hello everybody today we’re going to be taking a look at functions in Python a function is a block of code which is only run when you call it so right here we’re defining our function and then this is our body of code that when we actually call it is going to be ran so right here we have our function call and all we’re doing is putting the function with the parenthesis es that is basically us calling that function and then we have our output throughout this video I’m going to show you how to write a function as well as pass arguments to that function and then a few other things like arbitrary arguments keyword arguments and arbitrary keyword arguments all these things are really important to know when you are using functions so let’s get started by writing our very first function together we’re going to start off by saying DF that is the keyword for defining a function then we can actually name our function and for this one we’re just going to do first underscore function and then we do an open parenthesis and then we’ll put a colon we’ll hit enter and it’ll automatically indent for us and this is where our body of code is going to go now within our body of code we can write just about anything and in this video I’m not going to get super Advanced we’re just going to walk through the basics to make sure that you understand how to use functions so for right now all we’re going to say is print we’ll do an open parenthesis we’ll do an apostrophe and we’ll say we did it and now we’re going to hit shift enter and this is not going to do anything at least you won’t see any output from this if we want to see the output or we actually want to run that function and some functions don’t have outputs but if we want to run that function what we have to do is just copy this and put it right down here and now we’re going to actually call our function so let’s go ahead and click shift enter and now we’ve successfully called our first function this function is about as simple as it could possibly be but now let’s take it up a notch and start looking at arguments so let’s go right down here and we’re going to say Define number underscore squared we’ll do a parenthesis and our colon as well now really quickly when you’re naming your function it’s kind of like naming a variable you can use something like X or Y but I tend to like to be a little bit more descriptive but now let’s take a look at passing an argument into a function the argument is going to be passed right here in the parenthesis so for us I’m just going to call it a number and then we’re going to hit enter and now we’ll write our body of code and all we’re going to do for this is type print and open parenthesis and we’ll say number and we’ll do two stars at least that’s what I call it a star and a two and what this is going to do is it’s going to take the number that we pass into our function it’s going to put it right here in our body of code and then for what we’re doing it’s going to put it to the power of two and so when the user or you run this and call this function this number is something that you can specify it’s an argument that you can input that will then be run in this body of code so let’s copy this right here and then put it right down here into this next cell and we’ll say five and so this five is going to be passed through into this function and be called right here for this print statement let’s run it and it should come out as I believe 25 that is my fault I forgot to actually run this block of code so I’m going to hit shift enter so now we’ve defined our function up here and now we can actually call it so now we’ll hit shift enter and we got our output of 25 now in this function we only called one argument but you can basically call as many arguments arents as you want you just have to separate them by commas so let’s copy this and we’ll put it right down here now we’ll say number squared uncore custom and then we’ll do number and then we’ll do power so now we can specify our number as well as the power that we want to raise it to so instead of having two which is what you call hardcoded we can now customize that and we’ll have power and now when we call this function we can specify the number and the power and both of those will go into this body of code and be run and we can customize those numbers so let’s copy this and we’ll say 5 to the power of three and let’s make sure I Ram this so let’s do shift enter and now we will call our function and let’s hit shift enter and we got 5 to the^ of 3 which is 125 and just one last thing to mention is if you have two arguments within your function and you are calling right here you have to pass in two arguments you can’t just have one so if we have a five right here it’s going to error out we have to specify both Arguments for it to work now let’s take a look at arbitrary arguments now arbitrary arguments are really interesting because if you don’t know how many arguments you want to pass through if you don’t know if it’s a one a two or a three you can specify that later when you’re calling the argument so you don’t have to do it upfront and know that information ahead of time so let’s define our function so we’re going to say Define and then we’re going to say number underscore args and we’ll do an open parenthesis and a colon now within our argument right here typically we would just specify here’s what our argument will be it will be number or it will be a word right but what we’re going to do is something called an arbitrary argument so it’s unknown so we’re going to put star and then we’ll say args now you will see something exactly like this typically if you’re looking at tutorials that’ll have star args in there or you’re looking at just a generic piece of code this is what it will look like but for us we’re going to actually put number so again we have the star and then we have our arbitrary argument right here and then we’ll hit enter and we’re going to say print open parentheses and this is where it’s going to get a little bit different so we’re going to say number and then we’re going to do an open bracket and let’s say zero and then we’ll do that times and then we’ll say number again with a bracket of one so in a little bit once we run this and then we call this number args function right here we’re going to need to specify the number zero and the number one that’s going to be called so let’s go ahead and run this and then we are going to call it and let’s say 5 comma 6 comma 1 2 8 so right up here we did not know how many arguments we were going to pass through it could be five it could be a thousand and we could also call in a tuple and that’s what this is right here we’re calling in a tup so what it’s going to do now is when it calls this number it’s going to call the very first within that tupal which will be that five and then it’ll also call in this number which will be the first position which is the six so let’s hit shift enter and it’s going to multiply these numbers together so five * 6 is equal to 30 now like I just said this is a tuple so we don’t actually have to write out these numbers like we just did we can pass through a tuple when we are actually calling this function let’s do that right up here let’s just create um let’s call it argor Tuple and we’ll do open parentheses and we’ll do the same numbers let’s just copy it make it easier and now we’ve created this tupal right here which we can then pass in and this is a lot more handy a lot more specific and this is most likely how someone would do something like this but let’s now create this and now we can copy AR Tuple and pass it through now really quickly this is going to fail and I’m doing that on purpose but I want to show you what you need to do in order to pass through this tupal so right now it’s going to say Tuple index is out of range all you have to do in order to use this is you have to specify a star before it just like you did when you creating your argument up here we have to put a star in front of our Tuple that we just passed through and now let’s try running this and now it works properly now the last two things that we’re going to look at are keyword arguments and arbitrary keyword arguments there are more things that you can learn and do within functions but again I’m just trying to teach you the basics to make sure that you understand how they work so let’s go right up here and a keyword argument is kind of similar to this right here and let’s actually copy this and put it right down here now a keyword argument is very similar in that you’re going to specify your arguments right here but what we did up here let me bring this down when we actually called the function what we did was we just put a five and a three and when we did that it automatically assigned number to five and power to three and that’s totally fine and you can do that but if you want a little bit more control you can use a keyword argument so right here we could say our is equal to five and number is equal to three so I just switched it around right number was assigned to five and power was assigned to three but I just switched it to show you how this might work let’s run both of these and now it’s 3 to the^ of 5 which is 243 so that essentially is a keyword argument again it just gives you a little bit more control you don’t have to put them in specific positions like if you’re just calling multiple arguments now let’s come right down here we’re going to create basically another custom function uh so for this one we’re going to write Define number underscore org and then we’ll do an open parenthesis a colon and enter and what this one is is is this one is a keyword argument or an arbitrary keyword argument now to specify an arbitrary argument all we did was a star and then we input number but if we’re doing a keyword argument we actually have to have two stars right here so let’s start taking a look and again if you’re doing arbitrary it means we don’t really know how many keyword arguments we want to pass into our function so we’re just going to put star star number and then later within our body of code and when we’re calling it we’ll be able to specify it and just like the arbitrary argument before the arbitrary keyword argument means we really just don’t know how many keyword arguments we’re going to need to pass into our function so to demonstrate this let’s write print do an open parenthesis and we’ll say my oops need to do an apostrophe my number is we’ll do just like that little space and we’ll say plus and this is kind of where it gets a little interesting or a little bit more tricky so what we’re going to say is number So This Is Us calling our number and then we’re going to do a bracket and then I’m actually going to go to calling the function it’s a little bit backward or a little bit different than what you might think but when we’re calling it what I’m going to do is I’m going to say integer is equal to let’s just do some random number now when we’re calling that keyword within our body of code what we’re going to do is we’re going to actually type out integer just like this and this looks a little bit different but what this this allows us to do is we can put as many keyword arguments in here as we want later and I’ll show you in just a second but for us we’re just creating this key and this value when we are calling it within the function so now when we create this and we run this oh whoops I forgot this has to be a string um so let’s run this again now we will say my number is 2309 then we’re going to add we’ll say plus and this isn’t going to look great but we’ll say my other number this will all be in the same line that’s okay my other number and then we’ll say number and we can specify again what we want in there so now we can go down here to where we’re calling it we’ll just put a comma and we’ll say integer oops integer 2 is equal to we’ll do a random number and then we’ll put integer two right here and then we’ll add plus right here so we don’t error out we’ll create this we’ll run this and as you can see both numbers were passed through again the syntax is terrible but now you can see that you have this arbitrary keyword argument right here and all we have to do is put number number and we can pass through as many of these arbitrary keyword arguments as we want as long as we just specify within our function when we’re calling it hello everybody today we’re going to be talking about converting data types in Python in this video I’m going to show you how to convert several different data types in including strings numbers sets tupal and even dictionaries so let’s start off by creating a variable we’ll say numor int is equal to 7 and we can check that data type by saying type and then inserting our variable number undor int and that will tell us that our data type for this variable is an integer let’s go ahead and create another one we’re going to say numor string is equal to and for this one we’ll also do a seven but let’s check the type and and we’ll do an open parenthesis and we’ll say the type of num string and that one is a string now let’s say we wanted to add those we’ll say num underscore sum so the sum of numor int plus numor string now when we’re adding these two values it is not going to work it’s going to give us an error and it’s going to say unsupported operand for INT and string so it cannot add both an integer and a string what we need to do in order to add these two numbers is to convert that string into an integer so let’s go right up here let’s add another cell and let’s say numor string undor converted is equal to and we want to convert it into an integer so all we have to do to convert it into an integer is type int and then we’re going to say numor string and that is as easy as it’s going to get all we have to do is say integer with our numb string inside of it and then it’s going to convert it and we can even check it right after by saying type num string converted and let’s run this and now we can see that it was converted into an integer so now let’s add that num string converted right here let’s copy and replace that string with the string converted and let’s actually print out that numor sum and it worked properly now we did not specify what type of value this Num Sum was going to be but because it was two integers in here it’s going to automatically apply that data type of integer to that num suum let’s go right down here and now let’s look at how we can convert lists sets and tupal so now let’s say we have a listor type and that’s equal to 1 2 3 and we can check it again by saying type and that is a list let’s say we want to convert it to a tuple it’s fairly easy all we’re going to do is write Tuple say listor type that listor type is now going to be a tupal and we can check that by saying type and wrapping it around this tupal and it shows us that it is converting that list into a tupal now we can also convert a list into a set but it may change the actual values within it let’s check that out really quickly so let’s say we have this list and let’s add a few more values to this just like that now let’s say we want to convert it to a set so we’re going to run this and we’ll say set of listor type and let’s try running this and see what the output is so this is something that you really need to be aware of when you are converting data types because set does not act the same as a list a set is basically going to take the unique values in the list and convert it to a set and it fundamentally changes the data that was in that original list and just to check the data type we can say type I’m just doing this for all of them and as you can see that is now a set now let’s go down here and take a look at dictionaries now let’s say we have a dictionary called dictionary type and we’ll do a squiggly bracket and we’ll say name and we’ll do a colon and we’ll say Alex then we’ll do age and a colon and we’ll say 28 and then we’ll do hair col and so really quickly let’s take that dictionary type and just confirm that it is a dictionary and it is and now what we’re going to do is take a look at all the items within that dictionary so we’re going to do dictionary type. items open parenthesis and this is going to show us all the items within it now we can also take this and look at something like the values and when we run that these are our values So within our dictionary we have items and that’s what this is right here this is one item and then within that we have our values which are right here so Alex 28 and Na and then we have something called a key and this is the key the name age and hair are all keys and we can look at that by saying dot keys so let’s say we want to take all of the keys and put that into a list what we’re going to do is we’re going to take this right here to say list we’ll do an open parenthesis we’ll type that in right there so it says a list and we’re converting these Keys into a list and let’s run that and now this is a list and let’s just check the type as well just to confirm and as you can see it was converted properly into a list and we can do the exact same thing with value Val and the values can also be converted into a list now we can also convert longer strings that aren’t just numbers like we did above in our very first example so let’s do longcore string and we’ll say I like to party now we’re going to take this string and we’re going to say list long string so we’re going to convert this string into a list and let’s see what happens so it took every single character in that string and put it into a list and we could also do a set as well that one’s a lot shorter because it’s only looking at unique values so that is how you convert data types in Python hello everybody today we’re going to be working on building a BMI calculator in Python now before we get started I want to show you this BMI calculator that I found online and it shows you the basic calculation that they use and that’s the one we’re going to use in this video and they also have this calculator right down here and some ranges that we can use for our calculator as well so for reference I weigh about 170 I’m about 59 let’s calculate this so I’m about a 25.1 BMI which falls into the overweight category that’s unfortunate but we can see exactly how this works and how RS should work when we actually build it so we’re going to kind of reference this throughout the video so let’s go right over here to our BMI calculator we need to calculate weight and height and then run this calculation right here so let’s go ahead and copy this and we’re going to put it right down here and so now we have our calculation so what we need is we need input from a user and there is an input function within python that we’re going to be using so let’s actually give me a few more cells so the first thing that we need to calculate is their weight let’s type out weight right here we’ll say weight is equal to and this is where we’ll use our input function so we’ll say input and when we actually run this it’s just going to give us this blank square or a user can input something we’ll say Alex so this is our output is what the actual user input and it does save it to this variable so if we say print weight it will still print out Alex now this is where we want the user to just like we did before where they’ll input their weight so we want to kind of give them a prompt for this we’ll put a string in here so I’ll do a double quote and then I’ll say enter your weight in and we’re using pounds say pounds colon space so now when we do this it’ll say enter your weight in pounds I’ll say 170 and then when we run this it does store that now let’s do print I should have saved it wait again oops now it’s only storing the value of 170 it’s not actually storing this string right here so that’s really important for when we do our calculations later um I’m going to I’m going to save this right down here because I’m sure I’m going to use that later um so we have that it’s working now we need to also do our height so let’s copy this and we’ll put it right here and we’ll do height and enter your height in inches so now for this one if we hit enter it’s actually running let’s stop it really quick and interrupt it let’s try running this so it’s going to say enter your weight and pounds that’s the first input say 170 and then when I hit enter it’s going to prompt me for that second input and so in inches 59 is 69 in and then I can hit enter again and now we have both of our inputs now we need this calculation right down here and just like that so now we have weight in pounds * 703 divided by height in inches by height in inches so we actually have weight and it’s already written in there but I’m just going to do it like this we’ll do weight time 703 so that’s pounds there our weight in pounds time 703 divided by now we have our height in inches times the height in inches so this is our calculation right here so let’s do this exact same thing let’s run this and this times of course is not going to work oops we need to do our star for both of these right now this is our calculation so let’s run this so we have 170 and that’s pounds and inches was 69 hit enter and it says cannot multiply the sequence of non- integer type of string Ah that’s because these are being stored in strings if right down here I do and we’ll do type of height we run that this is actually a string so we want to change that cuz we don’t need that anymore that so we don’t want it to be a string we need those to be integers or Floats or really anything besides a string it just needs to be numerical so integer float really so let’s do integer and we’ll wrap that input in it and we’ll do the same thing for this one now we have an integer for our weight an integer for our height so now when we’re running this calculation it should work properly let’s run this again our pounds are 70 our height is 69 in and it’s not giving us our output because we’re not printing anything okay so I just need to do print BMI so let’s try this again 1 70 69 and there is our BMI 25.1 so it worked the exact same as this one so they input well we input our height we inputed our or we inputed our weight we inputed our height and then it calculated rbmi the next thing that we need to do is we need to kind of give the user some context is that good is there BMI in within a good range a bad range we don’t know uh so let’s go ahead and I’m going to see if I can copy this know if this will work or not let’s go ahead and copy this right down here perfect so what we now need to do is we need to say okay if the user has given us this input we want to give them or tell them if they are a normal weight overweight obese severely obese anything like that and we have these ranges so that should help us out quite a bit so let’s just write our if statement and then we’ll include it up here but let’s go down here and we’ll say if and then we’ll do BMI and let’s just say BMI is greater than zero so if it’s greater than zero if they had any input where the BMI was not zero which should be every time if they do it properly don’t you know put a string in there or something or type out 40 which maybe we should make a prompt for that if that happens then we can say if we’ll do BMI and now we need to give that first range so this range right here so if it’s under 18.5 so we need to do a less than so if it’s less than 18.5 and it just says under it doesn’t say under or equal to so I’ll keep it at 18.5 so if it’s under 18.5 then let’s give kind of the output we’ll say print and the output or the basically the prompt is underweight so we’ll just say you are under under case underweight and just like that um then we’re going to pass several ellf statements through here well let’s just say else so I guess this would be like if they are if they don’t input something properly or something messes up maybe I we could write something like um print oops I’m thinking all this through we can write print enter valid inputs or something like this or we can always change that but let’s really quickly let’s run this okay so I’m not in that range uh let’s make the next one so then I can be within a certain range oops and we need we should need one more a minimum so we’ll say LF and LF these next two are this 24.9 so it’s going to check this one first so if it’s 18.5 or below 18.5 it’s automatically going to print this one so this next one we don’t have to do like a range or anything we can just say if it’s below if it’s between 25 and 20 9.9 so this one actually should be less than or equal to um this one is normal oh whoops 24.9 so this one is 24.9 this one is going to say you are normal weight so let’s run this now let’s see BMI was 25.1 oh guys I’m just messing up here I apologize all right this is the one that I was part of so now it’s going to be part of the overweight crowd now let’s run this and now our prompt is you are overweight because remember the BMI was saved right here as 25.1 down here if we run through this it’s saying no you’re not in oops get rid of that no you’re not in under 18.5 you’re not under 24.9 if you are under 29.9 you are overweight so that did work properly so that’s really good and I don’t think I want this to be our output for the person because we’re going to add this up here it’s just going to give us the BMI and then the output is going to say you are overweight uh let’s make it a little bit more customized um I’m going to say name is equal to input and then we’ll say enter your name um so it’ll be enter your name we’ll do Alex 70 69 there’s our BMI now it’s going to run through this logic or it will run through this logic in just a second when we actually finished this then we have 34.9 and let’s do one more oops and then this one’s going to be for 39.9 so this one was overweight this one is obese severely obese OB we’ll say severely you spell it severely obese and then anything that’s over that 40 and over so if it’s not this one anything else should be S morbidly obese so actually this else statement right here should say uh you are you are severely obese this is going to say morbidly morbidly obese now I added that name up here here because I wanted to add that down below actually so we’re going to say uh name plus and then we’ll do like comma you are underweight so it’ll be a little bit more personalized uh I think it’ll I think it’ll be a nice touch I really do we’ll do it like this and we’ll say you and let’s go back and do that to all of them and let me see how quickly I can do this oh whoops what I do got rid of that name plus u like that geez you guys are seeing me mess up a ton name plus you and then name plus you so now let’s run this and now it’s a little more personalized it says Alex you are overweight so this is all really good now this is an if statement um what we had done before I think is actually what we should put right down here so we’ll say else and then if that doesn’t work we’ll say what do we say enter valid input we’ll just put that um and let let me see if I can test this out don’t I don’t know if this will error out or if this will even work let me just see if I can mess with it and see if I can get it to work actually let’s copy this we’re going to copy this whole thing we’re going to include it right here and now we have basically our entire calculator so um let’s run this enter your name we’ll say Alex enter your pounds 170 Ander your inches 69 and then it’s going to say 25.1 Alex you are overweight and that’s perfect we could even go as far as adding like some feedback we could say you are overweight and then it would be a period and we could say um you need to exercise more stop sitting and writing so many python tutorials so now if we run this we’ll do Alex 17069 it says Alex you are overweight you need to exercise more and stop sitting and writing so many python tutorials period and that’s it this is the entire project um you can go a ton farther you can include much more complex logic you could even build out a UI to create your own you know app just like this where it has this input and this UI you can build that out with in jupyter notebooks with python um but that’s not really what this tutorial is for this is just to kind of help you um think through some of the logic of creating something like this hello everybody in this lesson we’re going to be taking a look at beautiful soup and requests now these packages in Python are really useful these are the two main ones that I use when I was first starting out with web scraping it can get a lot of what you want done in order to get that information out now of course there are other packages that you can use that may be a little bit more advanced but again this is just the beginner Series in a future series we’ll look at other packages as well that have some more advanced functionality so what we’re going to be doing is we’re going to import these packages and then we’re going to get all of the HTML from our website and make sure that it’s in a usable State and then in the next lesson we’re going to kind of query around in the HTML kind of pick and choose exactly what we want we’ll look at things like tags variable strings classes attributes and more so let’s get started by importing our packages what we’re going to say is from bs4 this is the module that we’re taking it from we’re going to say import and then we’ll do beautiful soup then we’re going to come down and we’re going to say import requests now let’s go ahead and run this I’m going to hit shift enter and it works well for me now if this do does not work for you you may potentially need to actually install bs4 so you may have to go to your terminal window and say pip install bs4 I’ll just let you Google how to do that if you need to do that CU it’s pretty easy but if you’re using Jupiter notebooks through Anaconda like how we set it up at the beginning of this python series then you should be totally fine it should be there for you the next thing that we need to do is specify where we’re taking this HTML from so what we need to actually do is come right over here to our web page and we need to get the URL so we’re going to go here we’re going to copy this URL and I’m just going to put it right here for a second and what we’re going to do is we’re going to be using this URL quite a bit so we just want to assign it to a variable so just say URL is equal to and then we’ll put it right in here now we can get rid of that so now this is our URL going forward this is where we’re going be pulling data from let’s go ahead and run this now we’re going to use requests and what we’re going to do is we’re going to say requests.get and then we’re going to put in url now this get function is going to use the request Library it’s going to send a get request to that URL and it’s going to return a response object let’s go ahead and run this as you can see here I got a response of 200 if you got something like a 204 or a 400 or 401 or 404 all of these things are potentially bad something like a 204 would mean there was no content in the actual web page 400 means a bad request so it was invalid the server couldn’t process it and you don’t get any response if you you got a 404 that might be one that you’re familiar with that’s an error that means the server cannot be found the next thing that we’re going to do is take the HTML now if you remember we come right back here and we inspect this we have all of this HTML right here now on this web page specifically right now it’s completely static it’s not a bunch of moving stuff or anything like that usually when you’re looking at HTML if you’re looking at something like Amazon and those web pages can update but when you actually pull that into python you’re basically getting a snapshot of the HTM at that time so what we’re going to do is bring in all of this HTML which is our snapshot of our website and then we can take a look at it so we’re going to come right down here and now we’re going to say beautiful soup so now we’ll use the beautiful soup package or Library so we need to say beautiful soup and we’re going do an open parenthesis we’re going to do two things there’s two parameters that we need to put in here first we need to put in this get request we actually need to name this and we’ll call this page we’ll say page is equal to and let’s run this and now we’re going to put that page in here and what we’re going to say is text so the page is what’s sending that request and then the text is what’s retrieving the actual raw HTML that we’re going to be using then we’re going to put a comma here and what we need to specify is how we’re going to parse this information now this is an HTML so what we’re going to do is HTML just like this this is a standard this already built into to this Library so we don’t need to go any further but it’s basically going to parse the information in an HTML format now let’s go ahead and run this let’s see what we get and as you can see we have a lot of information and as we scroll down I’ll try to point out some things that we’ve already looked at in previous lessons umm something like this th tag that should be very similar that’s the title then we have these TD tags and then of course if we scroll down even further we’ll have things like ATR tag so these are all things that we looked at in that first lesson when learning about HTML now again we want to assign this to a variable so we’re going to say soup that’s going to say equal to this information right here now I’m not going to go into all the history behind beautiful soup what I will say is the guy who created this beautiful soup Library uh what he said was is that it takes this really messy HTML or XML which you can also use it for and makes it into this kind of beautiful soup so I just thought that was kind of funny uh but that’s why we’re calling it soup right here and we’re going to go ahead and run this and we’ll come right down here here and we’ll say print soup and let’s run it and now we have everything in here so we have our HTML our head we have some HR and some links in here let scroll down a little bit more and then we have our body right there and of course we have a bunch of information in here now in the next lesson what we’re going to be doing is learning how to kind of query all of this to take specific information out and basically understand a lot of what’s going on in this HTML to make sure we can actually get what we need now if this looks really kind of messy to you and it just doesn’t make a lot of sense there is one more thing that I’m going to show you and we’ll come right down here so we’ll say soup. prettify and if you’ve ever used a different type of programming languages uh pry is very common in a lot of them where it’ll just make it a little bit more easy to visualize and see uh you’ll notice that it kind of has this hierarchy built in whereas if we scroll up there’s no hierarchy built in it’s all just down this left hand side so if you kind of want to view it and just kind of visually see the differences this does help a lot but it doesn’t actually help a lot when you’re you know querying it or using you know find and find all which is what we’re going to look at in the next lesson now the first thing that we need to learn is HTML HTML stands for hypertext markup language and it’s used to describe all of the elements on a web page now when we actually go to a website and start pulling data and information we need to know HTML so we can specify exactly what we want to take off of that website so that’s where HTML comes in and we’re going to look at the basics understanding just the basic structure of HTML then we’ll go look at a real website and you’ll kind of see that’s a little bit more difficult than what we just have right here but this is the basic building blocks to get to what the HTML actually looks like on a website now this is basically what HTML looks like we have these angled brackets with things like HTML head title body and then you’ll notice that at the end we’ll have a body and then we’ll have a body at the bottom this forward SL body denotes that this is the end of the body section in HTML so everything inside of this is within this body so there is this hierarchy within HTML we have HTML and HTML at the bottom which encapsulates all the HTML on the website then we have things like head and head body and body now Within These sections we usually have things like classes tags attributes text and all these other things things that we’ll get to in different lessons but one of the easiest ones to notice and look at are tags things like a P tag or a title tag now Within These tags because this is a super simple example we have these strings here my first web page and this is what’s called a variable string and this is actual text that we could take out of this web page now that you understand the super basics of HTML let’s actually go to our website and I’m going to have a link down below but it’s going to be this one right here this is basically just a website that you can you know practice web scraping on it’s called scrape the site.com and what we’re going to do is look at the HTML behind this web page and you can do this on any website that you go on so we’re going to right click we’re going to go down to inspect now right off the bat this looks a lot more complicated and a lot more complex than the very simple illustration that we’re looking at but let’s kind of roll this up just a little bit you’ll notice we have HTML and HTM at the bottom we have a head and there is the end of the head and then a body and the end of the body so in a super simple sense it is similar but just the information that’s within it is a lot more difficult now if we look at this title right here this is our title tag if we click this little arrow this is our drop- down you’ll notice that here we have the string hockey teams forms searching imagination now let’s say we didn’t know we didn’t want to click on that and go find it there’s something that’s super helpful within this inspection page that you can click on right here it says select an element in the page to inspect it so we’re going to click on that and as we go through our page and let’s click on this title it’s going to take us to exactly where this is in our HTML this is extremely helpful extremely useful for example let’s say the data I want is down here I want to take in the Boston Bruins I can click on it and it’s going to take me to where that is exactly in the HTML this is where we can start writing our web scraping script to specify okay I’m looking for a TR tag I’m looking for a TD tag I’m looking for the class called team this is all information and things that we can use to specify exactly what we want to pull out of our web page now there are other things that we didn’t really look at as well in just our simple illustration let’s come right over here there’s things like HRS now these are hyperlinks so if we went and then clicked on this this is just regular text but inside of it is this hyperlink where if we clicked on it it would take us to another website and typically that’s denoted by this hre right here then you’ll typically see things like a P tag which usually stands for a paragraph now the last thing that I want to show you while we’re here and we’re going to learn a lot more in the next several lessons but if we come right down here there is this actual entire table here and let’s try to find this table and I’m having trouble selecting the entire thing but let’s select this team name and if we look at this team name you can see that this is encapsulating the tables this table tag now these are super helpful because it takes in the entire table now if we wrap this up and we look just at this it says class table and then we have the end of this table tag now when we open it it’s going to have all of this information so as you can see as I’m highlighting over it we have these th tags and we have these TD tags and even these TR tags which is the individual data and this is something that we’ll look at when we’re actually scraping all of the data from this table in a few future lesson so this is how we can use HTML how we can inspect the web page and see exactly what’s going on kind of under the hood and then in future lessons we’ll see how we can use this HTML to specify exactly what data we want to pull out thank hello everybody in this lesson we’re going to be taking a look at find and find all really we’re going to be looking at a ton of different things in this lesson this is where we really start digging in seeing how we can extract specific information from our web page but in order to do that let’s set everything up where we actually bring in the HTML like we did in the last lesson and we’re just going to write all this out one more time just for practice if nothing else and then we’ll get into actually getting that information from the HTML so we’re going to start by saying from bs4 import beautiful soup there we go and import requests we’ll go ahead and run this then we’re going to come up here grab our HTML or sorry our URL we’ll say URL is equal to to and we’ll have that right here now we need to say page is equal to and then we’ll do requests.get and then we’ll put in our URL right here and we’re going to come over here and run this and lastly we need to say soup so we’ll say soup is equal to beautiful soup there we go and then within our parentheses we need to specify the page. text because we need that and our parser which is HTML and there we go and let’s go ahead and run this let’s print it out make sure it’s working and there we go so we have our soup right here all this should look really similar to uh our last lesson and so now we’ brought in our HTML from our page we have a lot a lot a lot of information in here now really quickly let’s come over and let’s inspect our web page now in here we have a ton of information right we have bunch of different tags and classes and all these other things but how do we actually use these well that’s where the find and find all is going to come into play and they’re pretty similar and you’ll see that in just a little bit but let’s say we want to take uh one of these tags and let’s come down let’s say we just want to take this div tag now there’s going to be a lot of different div tags in our HTML but let’s just come right here let’s go down and let’s say we’re going to call soup we’re going to say soup that’s all of our information we’re going to say do find now within our parentheses we can specify a lot of different things but we’re going to keep it really simple right now we’re just going to say di let’s go ahead and run this what this is going to bring up is the very first div tag in our HTML and that’s going to be this information right here now let’s copy this and we’re going to do the exact same thing except we’re going to say find underscore all now let’s run this now we’re going to have a ton more information really all find and find all do is that they find the information now find is only going to find the first response in our HTML lead that’s the div class container let’s go back up to the top that’s our div class container but find all is going to find all of them so it’ll put it in this list for you so it’s going to have this first one and it goes down to uh this word SL div which should be right here and then we have have a comma which separates our next div tag so that is how we can use it now what if we want to specify one of these div tags we pulled in a ton of them but we want to just look for one of them well this is something where the class comes in handy because right now we have classes equal to container class is equal to co md-12 I don’t know what these are at the off the top of my head but um usually they’ll be somewhat unique and we can use these to help us specify what we’re looking for for example just kind of glancing of this we could also use this a tag if we wanted to look at this so we could say oh we’re looking for uh these H refs so we have an hre here and this right down here we have this hre as well which again uh if you remember from previous lesson that stands for a hyperlink now something like the class or the href um or these IDs these are all attributes so we can specify or kind of filter Down based off of these now let’s try it so what we can do is we can do class first and this is kind of the default uh within something like find all is you can even do class underscore we can come right back up we have this div and then here’s our class so again we have to have the div and the class if we took this a tag this is an a tag which would go right here with the class of something like navlink or something like navlink again down here we need to specify that more but we have our div so we’ll say CL Cole md12 right here and let’s go ahead and run this and now it’s going to pull in just that information now we’re still getting a list because we have multiple of these so this div class uh Co md-12 doesn’t just happen once if we scroll down we’ll see it multiple times something like right here uh or actually let me see right here so here’s this comma then here’s our next one so we have two of these uh div tags with a class of coal- md-12 and in each of these we have different information this looks like a paragraph with this P tag right here and let’s scroll back up uh so I also think we should try out doing something like this P tag typically these P tags stand for paragraphs or they have text information in them let’s try to P tag really quickly let’s just see what we get and let’s run this and it looks like we get multiple P tags now if we come back here you can see that there’s this information and it’s this information that we’re pulling in and I’m just you know noticing that from right here and then we have this information right here and it looks like there’s one more which is this hre which looks like this open source so data via and then that uh hyperlink or that link right there so we have three different P tags now just to verify and make sure that that’s correct what we could do is come over here we’re going to click on this paragraph it’s going to take us to that P tag where the class is equal to lead let’s come over here and look at this paragraph now we have another P tag right over here where the class is equal to glyphicon glyphicon education I have no idea what that means um and then we’ll go to our last one which is right here where the P tag is equal to uh we have AAG hre class uh and a bunch of other information so let’s say we just wanted to pull in this paragraph right here let’s go here and see how we can specify this information so it looks like P or the class is equal to lead that looks like it’s going to be unique to just that one so if we come down here we’re going to say comma and it was class so you can do uh class underscore is equal to and then we’re going to say lead let’s try running this and we’re just pulling in that information now let’s say we actually want to pull in this paragraph We actually want this text right here and this is a very real use case you know let’s say I’m trying to pull in some information or or a paragraph of text well let’s copy this and what we’re going to then do is say. text and let’s run this now we’re going to get an error right here and this is a very common error because we’re trying to use find all unfortunately find all does not have a text attribute we actually need to change this to find typically when I’m working with these find and find alls I’m using find all most of the time until I want to start extracting text then when I specify it I’ll change this back to find just like this now let’s try this and now we’re getting in parentheses this information now this is all wonky it needs to definitely be cleaned up a little bit but if we Cod back up it’s no longer in a list and we no longer have things like these P tags in here or this class attribute so we’re really just trying to pull out this information now again this does not look perfect we could even trying to do something like strip look like there’s some white space uh that cleans it up a little bit this definitely looks a little better um and we could definitely go in here and clean this up more but just for you know an example this is how we can then extract that information now let’s look at one more example this is some information and this is what we’re going to do kind of our little mini project in the next lesson on let’s say we wanted to take all this information well what if we wanted to pull in something like the team name that’s going to be in right here in this TR tag and each of these TR tags have th tags underneath them so if we scroll down you’ll notice that each row is this TR tag so let’s go ahead and search for let’s do th let’s just search for that first so let’s come right back up here let’s use this find all and we’ll get rid of this text for right now and let’s just say we want to look for the TR is that what we said we were looking for no th so let’s say we’re looking for th let’s go ahead and run this so we’re going to have underneath this th we have team name year wins losses and notice these are all the titles so these titles are the only ones with these th tags if we go down you’ll notice that the data is actually TD tags so now let’s go back and look for TD we’ll say d and this is going to be a lot longer we have a lot of information but these are all the rows of data let’s see if we can just get one piece of this data we’re going to get back we want just this team name that’s all we’re trying to pull in for now um and then we’ll try to get this row and then in the next lesson we’re going to try to get all of this information make it look really nice and then we’ll put it into a panda’s data frame so let’s just get this team name right now let’s go ahead we’re going to say th let’s run this and we have this th and now that we know we’re getting this information in we can do find let’s run this so there’s our team name I’m just going to say. text and again we can do do strip just like that and Bam we have our team name so you can kind of start getting the idea of how we’re pulling this information out we’re really just specifying exactly what we’re seeing in this HTML and and what’s really really helpful and you know something that I do all the time is I’m inspecting it I’m just kind of searching like how what do I want what piece of information do I want then I go ahead and click on it and then I’m looking you know where is this sitting in the hierarchy it’s within the body it’s within this table with the class of table then it’s down here where this TR tag and then this TD tag so I’m looking kind of at the hierarchy and I’m specifying exactly what I’m looking for so that is what we’re going to look at in today’s lesson that’s how we can use f find and find all we were able to look at classes and tags and attributes and variable strings which is this right here getting that text uh and variable strings and we will look at find and find all and how it’s pulling that information in and how we can specify exactly what we’re looking for hello everybody in this lesson we are going to be scraping data from a real website and putting it into a panda’s data frame and maybe even exporting it to CSV if we’re feeling a bit spicy now in the last several lessons we’ve been looking at this page right here and I even promised that we were going to be pulling this data but as I was building out the project I just I honestly thought it was a little bit too easy since in the last lesson we kind of already pulled out some information from this table and I want to kind of throw you guys off so we’re going to be pulling from a different table we’re going to be going on to Wikipedia and looking at the list of the largest companies in the United States by revenue and we’re going to be pulling all of this information so if you thought this was going to be easy in a little mini project uh it’s now a full project because why not so let’s get started uh what we’re going to do is we’re going to import beautiful soup and requests we’re going to get this information and we’re going to see how we can do this and it’s going to get a little bit more complicated and a little bit more tricky we’re going to have to you know format things properly to get it into our Panda data frame to make it looking good and making it more usable so let’s go ahead and get rid of this easy table we don’t want that one uh and we’re going to come in here and we’re just going to start off this should look uh really familiar by now we’re going to say from bs4 import beautiful soup I don’t know if you’ve noticed but I’ve messed up spelling beautiful soup in every single uh video I’ve noticed uh let’s run this and now we need to go ahead and get our URL so let’s come up here let’s get our URL say URL is equal to and we’ll just keep it all in the same thing really quickly because we know this by Heart by now right uh we’ll say request. get and then URL to make sure that we’re getting that information it give us a response object um hopefully it’ll be 200 that’ll mean a good response and then we’ll say soup is equal to and then we’ll say beautiful soup and we’ll do our page. text now we’re pulling in the information from this URL and then we use our parser which will be oops HTML and let’s go ahead and run this looks like everything went well let’s print our soup now this is completely new to you it’s completely new to me I don’t know what I’m doing uh but it looks like we’re pulling in the information am I right so we got a lot of things going for us uh the uh stuff was imported properly we got our URL we got our soup which is uh not beautiful in my opinion but let’s keep on rolling let’s come right down here now what we need to do is we need to specify what data we’re looking for so let’s come and let’s inspect this web page now the only information that we’re going to want want is right in here we’re going to want these uh titles or these headers whoops so we’re going to want rank name industry Etc and then we are for sure going to want all of this information let’s just scroll down see if there’s anything tricky in here all right that looks pretty good uh and there is another table so there’s not just one table in here there are two tables in this page so that might change things for us but let’s come right back and let’s inspect our page by using this little button right here and let’s specify in let’s see if I can highlight just this page oh it’s not oh let’s do that right there so now we have this uh Wiki table sorter now I’m going to actually come right here I’m going to copy and I’m just going to say copy the outer HTML I’m just going to paste it in here real quick and that’s a ton of information I didn’t think it was going to copy all of it and we’re just going to delete that I just wanted to keep that class uh because I wanted to then come right down here at the bottom and just see what this table uh looks like I don’t know if it’s part of it or if it’s a if it’s its own table um I can’t tell let’s look at this Rank and let’s come up so it says uh it’s under this table and it looks like it’s its own table but it says Wiki table sort sortable jQuery table sorter what could be do a sortable jQuery table Ser so it looks like there are two tables with the same class which shouldn’t be a problem if we’re using find to get our text because we should be taking the first one which will be this table and this is the table we want um and if we wanted this one we could just use find all and since it’s a list we could use indexing to pull this table right um but I think we’re going to be okay with just pulling in this one so let’s go ahead and let’s do our find so we’ll do soup. find and we could find all or we could just do find a table let’s just try this and see what we get and if it pulls in the right one that we’re looking for that’ be great now this does not look correct at all um I don’t know what table it’s pulling in oh maybe it’s this right here this might be a table yeah it is so we have this uh box more citations so actually we are going to have to do exactly like what I was talking about uh let’s pull this and we well we could do comma class uh right here and let’s do both you know what this is a learning opportunity let’s do both so let me go back up to the top because I need these um and what we’re going to do let come right down here I want to add in uh another thing actually I’ll just push this one up there we go so we’re going to say findor all let’s run this so now we have multiple and again we got that weird one first but if we scroll down here’s our comma and then here’s our wik Wiki table sortable and then we have rank name industry all the ones that we were hoping to see and I guarantee you if you scroll all the way to the bottom um we’re going to see potentially Wells Fargo Goldman Sachs I’m pretty sure those are um let’s see yeah here we go like Ford motor Wells Fargo Goldman Soxs that’s this table right here so now we’re looking at the third table but again this is a list so we can use indexing on this and we’ll just choose not position zero because that’s this one right here which we did not like well now we’ll take position one let’s run this let’s go back up to the top and this is our table right here rank name industry this is the information that that we were actually wanting just to confirm rank name industry Etc so this is the information we’re wanting and we’re able to specify that with our find all and this is the information we want so we now want to make this the only information that we’re looking at so I’m just going to copy this we didn’t need to use our class for this one you could probably could have um but we could so let’s actually um put this right down here this will be our table we’ll say equal to but then I’ll come right here and I’m going to say soup. find this is just for demonstration purposes we do table comma glcore is equal to and then we’ll look at this right here whoops me do this let’s see if we get the correct output and let’s run this and looks like we’re getting a nun type object uh if I remember looks like the actual class is this right here so let’s run this instead and I got to get rid of the index there we go okay so we were able to pull it in just using the find so the find table class and it says Wiki table sortable at least that’s the HTML that we’re pulling in right here let me go back because I don’t I don’t know if that’s what I was seeing earlier let’s just get this rank let’s go back up where’s the rank go rank there we go so here’s our Rank and let’s go up to the table and there’s our class yeah and and that’s just uh to me that’s a little bit odd so it says Wiki table sortable jQuery Das table sorder right here but in our actual um in our actual python script that were running it was only pulling in the wiki table sortable so it wasn’t pulling in the jQuery dasht sorter why uh I’m not 100% sure but all things that we’re working through and we were able to uh we were able to figure out so we’re going to make this our table we’re going to say tables equal to uh soup. findall and let’s run this and if we print out our table we have this table now this is our only data that we are looking at now the first thing that I want to get is I want to get these titles or these headers right here that’s what we’re going to get first so let’s go in here we can just look in this information you can see that these are with these th tags and we can pull out those th tags really easily let’s come right down here we’re just going to say t and we can get rid of this let’s run this now these are our only th tags because everything else is a TR tag for these rows of data so these th tags are pretty unique which makes it really easy which is really great because then we can just do worldcore titles is equal to so now we have these titles but uh they’re not perfect but what we’re going to do is we’re going to Loop through it so I’m going to say worldcore titles and I’ll kind of walk through what I’m talking about is in a list and each one is Within These th tags so th and then there’s our um string that we’re trying to get so we can easily take this list and use list comprehension and we can do that right down here so I’m going to keep this to where we can see it um we’ll do worldcore tore titles that’s equal to now we’ll do our list comprehension should be super easy uh we’ll just say for title in worldcore titles and then what do we want we want title. text that’s it um because we’re just taking the text from each of these we’re just looping through and we’re getting rank then We’re looping through getting name looping through getting industry that’s it so let’s go and print our world table titles and see if it worked and it’s did uh this looks like it needs to be cleaned up just a little bit so let’s go ahead and do that while we’re here before we actually put it into the uh P’s data frame oops I just wanted uh I just wanted this actually so what we’re going to do is try to get rid of those back slash ends if we do dot strip that may actually not work yeah uh because this is a list what we need to do is we can actually do it dot. text. strip right here let’s try to do it in there there there we go so now we have uh this and now this world tables is good to go now I’m actually noticing one thing that may be odd yeah so we have rank name industry it goes to headquarters but then in here we’re getting rank name industry and then the profits which is from this table right here which we don’t want uh let’s scroll back up let’s kind of backtrack this and see where this happened we did find all table we’re looking at the first one right and then we’re doing [Music] headquarters uh so we’re doing print table ah okay I think I found the issue here and let’s backtrack again this is we’re working through this together we’re going to make mistakes uh the table is what we actually wanted to do we just did soup. findall th which is going to pull in that secondary table um jeez we were not thinking here um so now we need to do find all on the table not the soup because now we were looking at all of them oh what a rookie mistake okay uh let’s go back now let’s look at this now it’s just down to headquarters okay okay let’s go ahead and run this let’s run this now we just have headquarters now let’s run this now we are sitting pretty okay excuse my mistakes Hey listen you know if it happens to me it happens to you I promise you this is you know this is a project this a little U little project we’re creating here so we’re going to run into issues and that’s okay we’re figuring out as we go now what I want to do before we start pulling in all the data is I want to put this into our Panda data frame we’ll have the uh you know headers there for us to go so we won’t have to get that later and it just makes it easier uh in general trust me so we’re going to import pandas as PD let’s go ahead and run this and now we’re going to create our data frame so we’ll say PD dot now we have these world uh t titles so what we’re going to do is pd. data frame and then in here for our columns we’ll say that’s equal to the world table titles and let’s just go ahead and say that’s our data frame and call our data frame right here let’s run it there we go so we were able to pull out and extract those headers and those titles of these columns we’re able to put it into our data frame so we’re set up and we’re ready to go we’re rocking and rolling the next thing we need let’s go back up next thing we need is to start pulling in this data right here so we have to see how we can pull this data in now if you remember that we had those th tags those were our titles as you can see I’m highlighting over it but down here now we have these TD tags and those are all encapsulated within a TR tag so these TR represent the rows right then the D represents the data within those rows so R for rows D for data so let’s see how we can use that in order to get the information that we want so let’s go back up here just going to take this cuz again we’re only pulling from table not soup not soup what were we thinking um and let’s go ahead and let’s look at TR let’s run this now when we’re doing this TR these do come in with the headers so we’re going to have to later on we’re going to have to get rid of these we don’t want to pull those in um and have that as part of our data but if we scroll down there’s our Walmart um we have the location these are all with these TD tags and then of course it’s separated by a comma then we have our td2 so above we had our td1 so Row one row two Row three all the way down now we will easily be able to use this right because this is our column data and we can even call it that column underscore data is equal to we’ll run that um and what we’re going to do is we’re going to Loop through that cuz it was all in a list so we’re going to Loop through that information but instead of looking at the TR tag we’re going to look at the T D tag so let’s come right down here we’ll say for the row in column row and we’ll do a colon now we need to Loop through this we’ll do something like row. findor all and then what are we looking for we’re not looking for the TR looking for the TD and just for now let’s print this off see what this looks like apparently I didn’t run this uh column data that’s why and let’s run this and what we actually need to do is something almost exactly like this and I’m going to put it right below it um instead of printing this off because again this is all in a list we’re using find all so we’re we’re printing off another list which isn’t actually super helpful um for each of or all these data that we’re pulling in what we can do is we can call this uh the rowcor data and then we’ll put the row data in here so we’ll say four and we’ll say in row data so we’ll just say for the data in row data and we’ll take the data we’ll exchange that and now instead of uh World Table titles we can change this into uh individual row data right and now let’s print off the individual row data so it’s the exact same process that we were doing up here and that’s how we cleaned it up and got this and we may not need to strip but let’s just run this and see what we get there we go um and strip I’m sure was helpful let’s actually get rid of this yeah strip was helpful it’s the exact same thing that happened on the last one so let’s keep that actually let’s run this and now let’s just kind of glance glance at this information let’s look through it this looks exactly like the information that’s in the table let’s just confirm with this first one uh 25 uh two what am I saying 572 754 2.4 2300 57275 2.4 2200 so this looks exactly correct now we have to figure out a way to get this into our table because again these are all individual lists it’s not like we’re just you know putting all of this in at one time we can’t just take the entire table and plop it into um into the data frame we need a way to kind of put this in one at a time now if you’re just here for web scraping and you haven’t taken like my panda series that’s totally fine that’s not what we’re here for anyways um but what we can do we’ll have our individual row data and we’re going to put it in kind of one at a time now the reason we have to do that is because when we had it like this and let’s go back when we had it like this it’s printing out all of it but what it’s really doing and let’s get rid of it um what it’s really doing is it’s kind of doing it like this it’s printing it off one at a time and it’s only going to save that current row of data this last one it’s only going to save that as it’s looping through so what we actually want to do is every time it Loops through we append this information onto the data frame so as it goes through and eventually it’s going to end up with this one but as it goes through let’s run this as it goes through it puts this one in and then the next time it Loops through it puts this one in and the next time it Loops through Etc all the way down um so let’s see how we can do this so we have our data frame right here let’s get rid of this let’s bring our data frame in now again like I just mentioned if you don’t know pandas and you haven’t learned that uh you know go take my uh series on that it’s really good and we do something very similar to this in that Series so I’m not going to kind of walk through the entire logic um but there is something called l which stands for location when you’re looking at the index on a data frame and we’re going to use that to our advantage so we’re going to say the length of the data frame so we’re looking at how many rows are in this data frame and then we’re going to say that’s our length then we’re going to take that length and use it when we’re actually putting in this new information pretty um pretty cool so we’re going to say df.loc then a bracket and we’re putting in that length so we’re checking the length of our data frame each time it’s looping through and then we’re going to put the information in the next position that’s exactly what we’re doing let’s go ahead and put in the individual row data um so let’s just recap We’re looping through this TR this is our column data so these TR that’s our row of data then we’re as as We’re looping through it we’re doing find all and looking for TD tags that’s our individual data so that’s our row data then we’re taking that that data each piece of data and we’re getting out the text and we’re stripping it to kind of clean it and now it’s in a list for each individual row then we’re looking at our current data frame which has nothing in it right now we’re looking at the length of it and we’re appending each row of this information into the next position so let’s go ahead and run this it’s working it’s thinking and it looks like we got an issue and not set a row with mismatched columns now we’re encountering an issue not one that I got earlier but we’re going to cancel this out we’re going to figure this out together so let’s print off our individual row data let’s look at this this one is empty uh this is I’m almost certain is probably the issue um I didn’t encounter this issue when I wrote these uh when I wrote this lesson um but I’m almost certain that this is the issue right here so let’s do the column data but let’s start at position um let’s try one and not parentheses I need brackets because this is a list right so it should work and there we go so now that first one’s gone so now we just have the information I didn’t even think about that um just a second ago but I’m glad we’re running into it in case you ran into that uh issue let’s go ahead and try this again and it looked like it worked so let’s pull our data frame down I could have just wrote DF let’s pull our data frame down and now this is looking fantastic fantastic now um these three dots just mean there’s information in there just doesn’t want to display it but it looks like we have our rank we have our name have the industry revenue revenue growth employees and headquarters for every single one so this is perfect now this is exactly what I was hoping to get now you can go in and use pandas and manipulate this and change it and you know dive into all the information in there but we can also export this into a CSV if that’s what you’re wanting so we could easily do that by saying we’ll do DF do2 CSV and then within here we’re just going to do R and specify our file path so let’s come down here to our file path then we’ll go to our folder for our output so we’re just going to take this path and let me do it like that so I have this path in my one drive documents python web scraping folder for output so you know I already made this um and I’m just going to put this right down here now I do have to specify what we’re going to call this um we’ll just call this companies and then we have to say CSV that is very important now if we run this I already know just because uh we have this Rank and this index here we’re going to keep this index in the output not great uh but let’s run it let’s look at our output there’s our companies and when we pull this up as you can see this is not what we want because we have this extra thing right here now if we’re automating this this would get super annoying so what we’re going to do is go back and just say index equals false let’s go out of here and now we’re just going to come right down here we’re going to say comma index equals false and so it’s going to take this index and it’s not going to import or actually export it into the CSV now let’s go ahead and run this let’s pull up our folder one more time and let’s refresh just to make sure should be good and now this looks a lot better so we’re able to take all of that information and put it into a CSV and it’s all there so this is the whole project so if we scroll all the way back up let’s just kind of glance at what we did here scroll down we brought in our libraries and packages we specified our URL we brought in our soup um and then we tried to find our table now that took a little bit of uh testing out but we knew that the table was the second one so in position one so we took that table we were also able to specify it using find but then we use the class and of course we just wanted to work with that table that’s all the data we wanted so we specified this is our table and we worked with just our table going forward of course uh we encountered some small issues user errors on my end but we were able to get our world titles and we put those into our data frame right here using pandas then next we went back and we got all the row data and the individual data from those rows and we put it into our Panda’s data frame then we came below and we exported this into an actual CSV file so that is how we can use web scraping to get data from something like a table and put it into a panda’s data frame I hope that this lesson was helpful I know we encountered some issues that’s on my end and I apologize but if you run into those same issues hopefully that helped uh but I hope this was helpful and if you like this be sure to like And subscribe below I appreciate you I love you and I will see you in the next

OneNote: Keyboard Shortcuts for Efficiency
OneNote has keyboard shortcuts to help you work more efficiently. Many shortcuts are the same across other Microsoft applications.
General Information
A keyboard shortcut is a combination of keystrokes that executes a task.
Screen tips provide a description of the command and its keyboard shortcut when hovering over different commands on the ribbons. To ensure screen tips are enabled, navigate to File > OneNote options > General tab > User interface options and select “Show feature descriptions in screen tips” in screen tips style.
Pressing the Alt key on the keyboard assigns keyboard shortcuts to the different ribbon tabs, allowing navigation and execution of tasks without a mouse.
A full list of shortcut keys available in OneNote can be found within the help files. The Help tab may need to be turned on in OneNote options. To turn it on, go to file, options, customize ribbon and make sure there is a tick next to help. The shortcut key for help is the F1 key.
Frequent keyboard shortcuts
Bold: Ctrl + B
Italics: Ctrl + I
Underline: Ctrl + U
Cut, Copy, and Paste also use the same keyboard shortcuts as other Microsoft applications.
OneNote Quick Access Toolbar: Customization and Use
The Quick Access Toolbar in OneNote provides quick access to frequently used commands. It can be customized to include the commands you use most often. This feature is available across all Microsoft applications.
Location and Appearance
The Quick Access Toolbar is located in the top left-hand corner of the OneNote interface.
By default, it may contain commands such as Undo and Touch/Mouse Mode.
The toolbar can be positioned either above or below the ribbon. To change the location, click the drop-down button on the right end of the toolbar and select “Show below the Ribbon”.
Customization
To add commands, click the drop-down button on the right end of the toolbar. This will display a list of popular commands that can be added.
Commands from the ribbon can be added by right-clicking on them and selecting “Add to Quick Access Toolbar”.
The “More Commands” option in the drop-down menu opens the OneNote Options, where you can add any command available in OneNote. This includes commands not listed on the ribbon.
To access all commands, in the OneNote Options, choose “All Commands” from the drop-down menu. To see commands not on the ribbon, select “Commands not in the ribbon”.
Commands can be removed from the toolbar via the OneNote Options.
Organization
The order of commands on the Quick Access Toolbar can be reorganized using the up and down arrows in the OneNote Options.
Separators can be added between commands to visually group them. Separators are available at the top of the list of commands in the OneNote Options.
OneNote: Inserting and Refreshing File Printouts
File printouts in OneNote allow you to insert the contents of a file stored locally or in OneDrive into a OneNote page. This can be any kind of file, such as a Word document, Excel spreadsheet, or PDF.
Key aspects of file printouts:
Insertion: To insert a file printout, select “File Printout” from the Insert tab. This will prompt you to select the desired file from File Explorer.
Content Copy: The content is printed directly into the page. It’s a copy, so the text isn’t directly editable from within OneNote.
Updating Content: To update the printout with any changes made to the original file:
Double-click the printout to open the original file in its respective application (e.g., Word).
Make the necessary edits and save the file.
In OneNote, right-click on the printout and select “Refresh Printout” to display the updated content.
Copying Text: The text from a printout can be copied and pasted elsewhere. Right-click the printout, select “Copy Text from this Page of the Printout”, and paste the text wherever it is needed. The text will then be editable.
As with other types of inserted content, you can use the send to OneNote tool to print to OneNote from other applications. When printing this way, you must select the notebook and section to send the content to.
OneNote: Managing Notebook Sections and Section Groups
Notebook sections in OneNote are a way to organize your notebooks. Sections function as dividers within a paper notebook and are displayed as tabs. Each section can contain multiple pages.
Here’s what you should know about working with sections:
Adding Sections The most direct way is to click the plus sign, which says ‘create new section’. Alternatively, you can right-click on any one of the tabs and select ‘new section’.
Renaming Sections Right-click on a section tab and choose ‘rename’.
Section Colors Section tabs are color-coded. To change the color, right-click on the tab, select ‘section color’, and choose a new color.
Reordering Sections To move a section, click and drag the tab to the desired position. You can also right-click a tab, choose ‘move or copy,’ and select where to move the section.
Copying Sections To copy a section, right-click on the tab, choose ‘move or copy’, select a location, and click ‘copy’.
Deleting Sections Right-click on a section tab and select ‘delete’. Deleting a section will also delete all of the pages within it. When you delete sections, pages, or anything from your notebooks, they go into the notebook recycle bin.
Section Groups
Section groups are a way to group different sections together, which is useful if you have a lot of information in one notebook. To create one, right-click on any of the tabs and select ‘new section group’.
To move sections into a section group, right-click on a section tab, select ‘move or copy,’ choose the section group, and click ‘move’. Unfortunately, in OneNote, there is currently no way to select multiple sections and move them all at once.
In OneNote for Windows 10, you can add sections at the bottom. You can also reorder sections by dragging them.
OneNote Tutorial: Getting Started with Microsoft OneNote – 3.5 hour+ OneNote Class
The Original Text
subscribe and click the bell icon to turn on notifications hello everyone and welcome to this course on onenote for microsoft 365. my name’s deb and i’m a microsoft i.t trainer and your excitable host for this course and the reason why i’m so excited is because i love onenote and i can’t wait to show you some of the awesome features available in this digital note-taking application which is really going to make you rethink how you go about the simple task of taking notes over the balance of this course i’m going to show you how to get started with onenote how to gather information from different sources how to insert different types of media files how to organize that information logically so it’s easier to read and find i’m going to show you how you can collaborate with others on team notebooks now this is a very comprehensive course and it offers a complete guide to all of the features available in the latest version of onenote so if that’s what you’re looking for then you’ve come to the right place now this course is divided down into 13 sections and i’ve tried to arrange these logically to correspond with the natural flow of how you would work in onenote now i’m going to be making some assumptions before we begin this course i’m going to assume that you have some familiarity with microsoft applications so maybe you are a word or an excel or a powerpoint user prior to coming to onenote and what i mean by this is that i won’t be going through the basics of how microsoft applications work per se i am going to assume you are reasonably familiar with the ribbon layout and the standard user interface that’s common amongst all microsoft applications and when it comes to the scope of this course i’m going to be working in the onenote for microsoft 365 desktop application i’ll be providing information on things like the mobile app and the online version but it will be a high level overview as opposed to a full training course in those specific parts now if you’re feeling a bit confused by what i’ve just said there don’t worry at all in the next module we’re going to start by running through the different versions of onenote that are available because as with all things in microsoft there are quite a few options but for now that is all i just want to say thank you so much for choosing this course i can’t wait to dive into it with you so with that said grab yourself a coffee and let’s get started hello everyone and welcome back to the course now i just thought i’d start out this section by running you through the different versions of onenote that are available because in my experience this is one of those things that causes a lot of confusion in fact very recently i was running a webinar on onenote and we got about halfway through and i had many of the participants say to me what you’re looking at on the screen looks nothing like what i’m looking at on my screen and we determined that we were actually using different versions of onenote so this is something you really have to watch out for so i’m going to run you through the different versions available and also let you know the version that i’m going to be using throughout the balance of this course if you are a windows 10 user what you might find is that you have access to the windows version of onenote because onenote now comes packaged with windows 10 so if you’ve downloaded that onto your pc or maybe you’ve bought a new laptop that has it already installed you’ll find that you will have a version of onenote 2016 already installed and ready to go on your pc so i’m using a windows 10 laptop and this is a fairly new laptop so i have this version installed so i’m going to jump down to my search bar at the bottom and i’m going to start to type in one note now i want you to ignore the onenote app which is showing underneath best match for the moment because that’s something different to the one underneath which is one note for windows 10. this is the one that comes installed with windows 10 and it looks completely different to the onenote desktop version and also the online version so if i very quickly open onenote for windows 10 you’ll see that it looks like this so if when you open up your version of onenote it looks very similar to something that i have here then you’re more than likely using the windows 10 version and a really quick and easy way to check that is that in the title bar at the top it will say onenote for windows 10. so this is one of the versions now this isn’t the version that i’m going to be using throughout this course and the reason why is that it doesn’t have quite as many features as the full desktop version however because a lot of people do have this on their pc for free without having to have any kind of 365 subscription at the end of each section of this course i am going to provide a module which basically runs through everything we’ve been through in the section but in the windows 10 version as well so if you do have this version you should still be able to follow along nicely so that’s the first version of windows 10 that you may or may not have available depending on what operating system you’re using now the second way that you can access onenote is through a microsoft 365 subscription and you can see here that i’m currently logged in to my online 365 portal and if you’re a bit confused by microsoft 365 it’s just the new name for office 365 so if you have a subscription to microsoft 365 then you should have access to onenote so if i click the little waffle or the app launcher at the top here you can see that one of the applications i have access to is onenote i can click it and it’s going to jump me into the online version of onenote and again this looks very different to the windows version and also the full desktop version that we’re going to open shortly now if you’re fairly used to using microsoft 365 you’ll know that this kind of online browser online portal is where you can come to access the lite versions of the applications so they’re intended for you to be able to update read things work on the go on whatever device you’re using as long as you’ve got an internet connection you can jump into your office 365 account and access online versions but these aren’t the full versions and because of that this also isn’t the version that we’re going to be covering in this particular course now i’m going to click on home for the time being because when you do have a microsoft 365 subscription when you log into the portal you’re able to download and install the full versions of all of these applications and you do that via this button just here install office and by clicking that and running through the setup process you’re then going to have the full versions of all of the applications available on your desktop so that’s exactly what i’ve done and once you’ve done that you’ll then be able to search for onenote it’s actually this one here so not the one with four windows 10 after it this is the full desktop version so you can click here to launch it or you can do what i’ve done and pin it to your taskbar and you’ll see mine is located down here with the rest of my microsoft applications so i can click to open it up and this is the feature rich desktop version and it’s this one that i’m going to be using throughout the balance of this course so what i’m trying to say to you here is if you predominantly work in the online version then this isn’t a training course that’s going to cover that however if you do have the desktop version and also if you have that free version through windows 10 then this course is going to be perfect for you just bear in mind there will only be one module per section that relates to the windows 10 version as we’re mostly going to be working in the desktop version phew quite a lot to take in there as always microsoft likes to make things a little bit confusing for everybody and just a final point to note there is a mobile app that you can download for windows phone android and ios and i will be doing a brief overview on the ios app at the end of this course so hopefully that is reasonably clear to everybody and we’re all on the same page with regards to the version we’re going to be using and what we’re going to be covering in this course i’m going to jump across to the next module where we’re going to start to explore some of the keyboard shortcuts in onenote so i’m going to go across there now and i hope to see you there now in this first module we’re going to talk about keyboard shortcuts and it wouldn’t be one of my courses if i didn’t start out with this module because keyboard shortcuts are such an important thing when it comes to being able to work efficiently not just in onenote but any microsoft application now if you’re coming to onenote having used word excel powerpoint or even outlook then you’ve got a bit of a head start here because many of the keyboard shortcuts are exactly the same in onenote as they are in those other applications at least the ones that you’ll use most frequently now if all things microsoft are completely new to you and you’re not entirely sure what i mean by a keyboard shortcut keyboard shortcut is essentially a combination of keystrokes that will execute a task and a lot of the time using a keyboard shortcut is a lot quicker than using your mouse to hunt through the different ribbons to find the task that you need and there are so many different keyboard shortcuts in onenote that you would never be expected to remember them all but most people have a catalog of about five to ten in their minds which they use frequently now as i mentioned the keyboard shortcuts in one note do bear a lot of similarities to the keyboard shortcuts in other microsoft applications so for example something like bold control b is the keyboard shortcut and that is the same across every single microsoft application italics is control i underline control u and of course we have things like cut copy and also paste with the same keyboard shortcuts now you’ll see that as i hover over these different commands on the ribbons i’m getting a little screen tip which not only gives me a little bit of description text so i know exactly what that command does it’s also showing me the keyboard shortcut now if for some reason when you hover over these icons you can’t see those screen tips i would advise you to turn them on so let’s just take a look at how we do that if we can’t see these screen tips so i’m going to jump up to file and you’ll find this in the onenote options and it’s this first general tab just here in this first group user interface options so in screen tips style make sure you have show feature descriptions in screen tips now if for some reason you find those completely annoying then you can also turn them off from here as well but soon as you turn those on it’s going to allow you to see those keyboard shortcuts in that screen tip text so that can be super useful now if you’re somebody who likes to work predominantly using the keyboard as opposed to the mouse if you press the alt key on your keyboard you’ll see that you get some keyboard shortcuts assigned to the different ribbon tabs so this is great because it enables me to navigate and do things without touching my mouse and i know a lot of people who are really into working with keyboard shortcuts use this option quite frequently it’s also really good if you have any wrist problems or something that prevents you from fully working with your mouse you don’t technically have to use it in order to work within onenote so for example if i want to navigate to the insert tab i can press capital n which is going to jump me to that tab and then i get a whole new list of keyboard shortcuts that i can use to execute a task so if i want to insert a picture i could press p and it’s going to open up file explorer and let me browse for the picture that i want to add and also with screens like this if you take a look at the bottom if i was to hit my enter key it’s going to open whatever i have selected now if i want to just cancel out of this window which i do i can use my tab key to move to cancel and then hit the enter key so i’ve been able to cancel that dialog box without touching the mouse at all so those alt key shortcuts are really useful now the only other thing i really want to mention to you regarding keyboard shortcuts here is if you’re somebody who does like their keyboard shortcuts and you want to see a full list of all of the shortcut keys available in onenote then you can find a list of those within the help files so you can see here in onenote i have a help tab and once again this isn’t a tab that’s turned on by default so if you can’t see help up here you’re going to want to jump to file go down to options and then jump into customize ribbon and on the right hand side here this is where you can select what ribbon tabs you can see in your onenote so just go into here and make sure that you have a tick next to help in order to be able to see that ribbon tab so if i hold my mouse over where it says help you’ll see that there’s also a shortcut key for this as well and that is the f1 key and again as you would expect that is the same across all microsoft applications so let’s jump into help and that’s going to open a pane up on the right hand side and what i can do is type in keyboard shortcuts and press enter to run that search and the top result i get is keyboard shortcuts in onenote and if i jump into here i get a lot of information about different keyboard shortcuts and then i can view all of the shortcuts divided down by category so i can jump to frequently used shortcuts and i can see all of them listed in here i then have shortcuts for formatting inserting items onto a page working with tables so on and so forth so this is a really great place to come if you want just to see a full list of all the keyboard shortcuts available in onenote now i will say that throughout this training course i’m going to try to use keyboard shortcuts as little as possible and the only reason for that is because it’s a lot more difficult for you to see what i’m doing if i’m using a keyboard shortcut as opposed to if i’m actually clicking on things bringing up menus so on and so forth so if you wonder why i’m not personally using them i will say that in my day-to-day work when i’m not recording a training course i use keyboard shortcuts all the time but i’m going to be using my mouse throughout the balance of this course so that’s it on keyboard shortcuts in the next module in this introductory section i’m just going to be talking to you a little bit about customizing the quick access toolbar again this is something you might have done in previous applications so if you’re familiar with how to do that then you can probably jump over the next module but if not stay tuned i’m going to show you how you can be more efficient by adding frequently used commands to the quick access toolbar i’m going to jump over there now so join me when you’re ready hi guys and welcome back to the course in this module we’re going to take a look at customizing the quick access toolbar now once again this is one of those features that’s available across all of the microsoft applications so if you are a excel powerpoint word user and you’re fairly familiar with how the quick access toolbar works and how to customize it then you can probably skip over this module and head straight to the next one however if this is all fairly new for you stay tuned and let’s run through why the quick access toolbar is useful and how you can customize it now the quick access toolbar you’ll see located in the top left hand corner and it’s this little toolbar just here so it’s kind of tucked away a little bit now i don’t have a great deal on my quick access toolbar at the moment just a couple of commands and that’s pretty much what this quick access toolbar is you can add whatever commands you like to it in particular commands that you use frequently to make them super easy for you to access so for example if i’m always inserting pictures into my onenote notebook instead of jumping to the insert tab and then selecting pictures from here i could essentially add this command to my quick access toolbar which then gives me one click access to that particular option now by default when you first open up onenote you’ll already see a couple of things assigned to your quick access toolbar so for me that is the undo command a very popular command ctrl z to take us back a step and also the command that allows me to switch between touch and mouse mode now i’m going to be going into that in more detail in the next module so i’m not going to delve into exactly what this command does right at this moment and then right on the end here we have this little drop down button and when i hover over it says customize quick access toolbar and what this is going to show you is a number of different commands that you could add to your quick access toolbar so i could add forward i could add redo print print preview so on and so forth so these are merely suggestions of popular commands that you might consider adding to that quick access toolbar now something else i want to draw your attention to here is as you can see currently my quick access toolbar is tucked away in the top right hand corner now whilst i don’t have too many options as to the location of this toolbar i do have one more option and that is i can choose to show it below the ribbon so i’m going to click that and you can now see that it pulls it down to below my ribbons now this is where i like to have my quick access toolbar because i just find it a lot easier to get to and less tucked out the way so let’s click our drop down again and look at how we can customize and add commands to this toolbar now if i wanted to choose any of these i can just select them so let’s add the redo button like so i could also add the print button and let’s add print preview as well and you’ll see it just builds a long list of all of these different commands which i can then execute simply by clicking on them so it’s a lot more efficient than having to find them in the ribbons or in that file area backstage now one thing you will notice is that obviously we just have a selection of commands which we can choose from here but what if you want to add a command that’s on the ribbon well as i said at the beginning if i insert a lot of pictures into my onenote notebook then what i could do is right click on the pictures command and say add to quick access toolbar to add that on and you’ll see that you have this option whenever you right click on any of these commands and of course i could carry on going and build myself up a nice long list of all of the commands that i access frequently now in addition to adding them this way through the right click menu if i click the drop down again you’ll see right at the bottom we have a more commands option and that’s going to jump you straight into the onenote options and into the quick access toolbar area so over on the right hand side of the screen you’re going to see everything that you currently have on your quick access toolbar and what you can essentially do is go through all of the commands available in onenote and add them in from here so it’s definitely worth noting that not every single command that’s available in onenote is listed out as a command on ribbons so what you could do is click the drop down here and i could say all commands which is going to show absolutely every command available in one note if i just wanted to see the commands that weren’t available to select from a ribbon i could select commands not in ribbon now i’m going to select all commands to bring up the full list that’s available so i’m going to scroll through and i can add a couple of things from here so let’s say customize tags is something i do all the time i’m going to select it click on the add button to add it over to my quick access toolbar and of course once i have it over here i could then choose to remove so let’s remove print preview if i want to get rid of any of these so i could go through this big long list just adding commands i use frequently to my quick access toolbar now another thing that you can do within here is you can reorganize the way these are listed out so for example undo and redo are kind of in the same category so i want these to be together so i’m going to click on redo and then i can use my arrows to move that up one maybe i want touch mouse mode to be right at the beginning so i’m going to select it and say move up just to put that at the beginning so you can organize your list however you like now something else you might want to add in here and again this is more of an organizational tip if you start to get quite a lot of icons on your quick access toolbar sometimes it’s nice to have a little bit of separation between commands of similar type and we can do that by adding in a separator now you’ll find separators available at the top of any of these lists that you select and it’s this just here i can click click on add to add in a separator and i can add in as many separators as i like so i’m going to add another one i can then use my up and down arrows to move these into position so i’m going to have one separator there and i’m going to move this one down two so now when i click on ok you can see how that looks on my quick access toolbar i now have these very faint lines in between separating out different groups of commands so it’s just a little bit easier on your eye to have them organized in this way as opposed to just a big long row of random icons so that is how you can customize your quick access toolbar and it is something i always advise people to do because it does really increase your efficiency when you’re looking for commands you use frequently in onenote in the next module we’re going to finish off this introductory section by talking about using onenote on a touch device so i’m going to grab a coffee head over there now and i look forward to you joining me hi guys welcome back now i didn’t want to finish up this introductory section without giving a bit of a shout out to all the touch screen users out there more and more these days people have tablet devices and also laptops that have touch screen capabilities i am in fact using one of those laptops as we speak and out of all of the microsoft applications onenote is the application that is most suited to people who use touch device with a stylus pen and you’ll see as we work through this course particularly in certain sections when it comes to things like handwriting things are a lot easier if you are using a touch device with a stylus because let’s face it trying to write a word using your mouse never works well so before we finish up this section i just want to run through a couple of the options for all of the touch screen users out there now currently i’m working with the mouse and keyboard and so i’m in what we call mouse mode now helpfully one of the default commands on my quick access toolbar is this option just here the touch mouse mode option so this allows me to toggle between using a mouse and using touch now when you’re using a mouse and keyboard the interface is really optimized for that particular usage whereas if we jump into touch you’ll see that the screen changes slightly more because it’s then going to optimize for people who use a touch screen so let me briefly switch into touch mode now the most obvious thing that’s changed here is that i have a lot more space between the different commands on the ribbons so what it’s doing here is just accommodating for your finger your finger is a lot bigger than your mouse pointer and so you need a little bit more room because the last thing you want to be doing is pressing one command and accidentally hitting two or three so if you’re watching this course now and you are using a touch device i would advise you to switch into this particular mode and remember if you can’t see this option on your quick access toolbar by default then you can jump into more commands and then find touch mouse mode in here and add it to make it super simple for you to switch between the two modes now we are going to be typing a lot of text throughout the balance of this course and again if you are using a touch device then you’re going to want to make sure that you know how to pull up your touch screen keyboard now mine’s located right in the bottom corner on my taskbar and you can see as i hover over it says touch keyboard and if i click that that’s going to pull up my touch keyboard and i can then go through and i can start to use that to type in different words and notes so make sure you know where that is because it’s going to make your life a whole lot easier as we’re going through this course now we’re going to dip back into touch a little bit later on particularly when we get to this section of the course here where we start to draw things as i said it’s a lot easier to do if you do have a touch screen with a stylus but of course as always i will try to accommodate both keyboard and mouse users as well as touch users so that’s it on touch i am going to very quickly toggle back to mouse and keyboard mode and i will see you in the next section hello everyone and welcome back to the course this is deb your host and we are about to get into section two which i’ve titled getting started with onenote and over the course of this section we’re going to learn some of the skills that you need to know in order to get going with onenote and we’re going to start out in this first lesson by just taking a look at how we open onenote i’m going to show you how to open a notebook and then we’re going to do a quick tour of the onenote interface so you understand the ribbon structure and the kinds of commands that you’ll find on the different ribbons so let’s dive in now as i mentioned in the previous section i’m going to be demonstrating one note for desktop so what i could do in order to launch onenote is click in the search bar down here and i’m using windows 10 type in onenote and you’ll see that i have onenote listed underneath my apps so i could launch it from here simply by clicking on this menu item but what i’ve actually done is i’ve pinned the application to my taskbar just to make it super simple for me to access and it’s all the way down here right in the middle i’m going to click to launch now when you open onenote for the first time it’s probably going to look something similar to this so you can see there right in the middle we have this big old message that says you don’t have any open notebooks and that would be correct i haven’t created a notebook and i don’t have an open notebook now one thing you’ll notice is that with no notebook open a lot of the commands on the menus are out so in order to give you a quick tour of this interface i’m going to need to either create a new notebook or open a notebook that i have saved off so i’m going to do the latter i’m going to open a notebook that i’ve already created and we are going to go into this in more detail a bit later on but for demonstration purposes let’s quickly run through the process now much like any other microsoft application you’ll see that we have our ribbon tabs at the top we have our file menu which jumps us into that backstage area and if you are familiar with other microsoft applications you’ll know that this is kind of where you’ll find those admin style tasks so if you need to create a new notebook open print share all of those kinds of things you’re going to find in here so what i want to do is i want to jump straight down to open and you’ll see at the top some of the notebooks that i’ve had open recently and these are notebooks that i have stored in onedrive and then if i scroll down i can see some more lists so on the right hand side i’ve got notebooks selected and this is showing me any notebooks that i’ve recently used so i could select to open one of these alternatively if i can’t see the notebook that i want to open listed either down here or at the top here what i can do is choose to open from other locations and jump across to my onedrive or maybe even browse my local drives to find a notebook that i want to use now as i said we’re going to get into this a bit more later on so for the time being i’m just going to open something that i’ve opened recently and i’m going to choose this one here that is my work trips notebook click to open it up so this is a very basic notebook but we’re not going to worry about the content too much at this time really what i want to do in this lesson is just run you through the interface so you kind of start to get an idea of where things are located on the different ribbons now again something that’s very consistent across all microsoft applications your home ribbon is going to contain all of the things that you’re probably going to utilize most often so we have our clipboard group which contains cut copy paste we have add text formatting options and also styles if we want to apply them we then have a big section here called tags and tags is something that’s really cool and we’re going to talk a lot about this a bit later on in the course i can email my page from here and i also have some interaction with outlook on the end here and again we’re going to cover this a bit later on moving across to the insert ribbon this contains all of the things that you can insert into your notebooks so that might range from things like tables file printouts attachments even excel spreadsheets you can also insert pictures whether they be saved on your local drives or located online you can add screen clippings or screenshots directly into your notebook and you can also do cool things like record audio and video from directly within your onenote notebook this is also where you would come if you wanted to use some kind of page template as well so the insert tab you come to whenever you want to insert something into your notebook we then have our draw tab and this is probably most useful if you are somebody who uses a laptop or maybe a touch device that has a stylus because this is where you can come to draw make annotations handwrite your own notes and insert things like shapes now whilst it is possible to do these things using a mouse a lot of the time it is quite hard to use a mouse to do handwriting as i said this does tend to work best if you’re using a stylus moving across to the next tab we have our history tab and this really relates to having lots of people collaborating on one notebook you’ll see as we move through the course you can share your notebook with team members other people and then everybody can jump into the notebook and make changes their own annotations things like that so the history tab really comes into play if you want to essentially see changes that have been made to a notebook by author if you want to find specific changes or even if you want to see different versions of your page and again we’re going to get into how all that works a little bit later on moving across we have our review tab and this is pretty much what you would expect to find on any review tab in your microsoft applications this is where you would come to spell check use the thesaurus check your accessibility change things like language or even password protector section we also have something in here called linked notes which is a very useful feature which we’ll explore in more detail later on in the course the view tab is where you can view your notebook or your page in different ways and you can also format your page background so if you want to change your page color or maybe you want to add raw lines to your page you can definitely do that you can do things like zoom in and out to make things a bit easier to see and also make modifications to how you’re displaying your window and then finally on the end here we have our help tab now as i mentioned at the beginning of this course the help tab isn’t always there by default if you think that you’re going to utilize this tab then it’s definitely worth jumping into onenote options and turning that tab on i’m not going to focus on this because we have already been through this tab earlier on in the course so aside from that ribbon structure underneath we have our quick access toolbar which we’ve seen how to customize and then we have our notebook and the way that a notebook is structured is it has sections and then it has pages so i liken this to a paper notebook that maybe you have dividers in the dividers are very similar to the different sections that we have up here and you can see them showing as tabs and then within each section i have pages and if you cast your eyes over to the right hand side in this blue panel you can see i currently have three pages milan rome and venice within the italy section and of course you can add sections and you can add more pages to each section and this is in general how all of the notebooks that you create will be structured don’t forget if you feel that you need a little bit more room when you’re working in your onenote notebook and you want to temporarily minimize the ribbon you can definitely do that by clicking on this small little up arrow over on the right hand side and this up arrow does have a keyboard shortcut control plus f1 and that’s going to minimize up your ribbon which gives you a little bit more room when you’re working in your notebook if you want to bring your ribbons back after you’ve collapsed them up if you click on any of the tabs the ribbon will drop down again if i click back on my notebook that ribbon’s going to disappear if you decide that you want to have that ribbon back permanently what you need to do is just click on one of the ribbons again to pull it up and then go over to the right hand side and click on the pin the ribbon icon again control plus f1 and that’s going to lock that ribbon in place so that is pretty much what your interface looks like when you open up a workbook so the main point i want you to take away here is this notebook structure you have your sections running in tabs across the top and each section can contain multiple different pages and we’re going to see in the next lesson exactly how we create a new notebook from scratch and how we start to add sections and pages so i’m going to jump over to the next module now and i look forward to you joining me hello everyone and welcome back to the course it’s time for us to start creating some stuff let’s start creating some content in wonderful onenote now in the previous module we took a quick tour around the onenote interface and of course we’re going to be dipping in and out of these ribbons and exploring all of the commands over the balance of this course but the first thing we want to do the most fundamental thing in one note is we want to create a new notebook and this is a very simple process so we’re going to go up to the file tab and as you would expect we want to make sure that we’ve got new selected now what you’ll see in here is essentially a split screen on the left hand side we have different locations so this is where we want to save a new notebook and then on the right we have a list of recent folders so recent folders that you’ve saved into are used now this is a reasonably new account that i’ve set up so currently i only have one recent folder listed and that’s my documents folder in onedrive and the way this works is that when you create a new notebook you essentially save it first which is why we’re being asked to select a location now i’m going to save my notebook into onedrive but before i do that let’s just take a look at the other options that we have so you could if you wanted to choose to save this directly to a sharepoint team site you could save it to this pc you can add a place so if you have more than one onedrive account you can choose to add those from here to make them easy to access alternatively if you just want to save your notebook locally you can do that by selecting browse and it’s going to jump you into file explorer and you can then jump in and choose a folder now one thing to note here if you want to share your notebook with other people then your notebook must be saved to location that’s shareable so for example saving your notebook to your desktop is not a shareable location whereas saving your notebook to maybe a network drive that you have within your company or even saving it to onedrive cloud storage those are considered shareable locations now whilst it is a good idea to have a little bit of an idea as to if you want to share your notebook right at the point where you’re creating it it doesn’t matter so much if you create it in one location and then change your mind because you can move your notebook at a later time if you then want to share it but what i’m going to do is i’m going to save to onedrive and i’m going to put it just in my onedrive train it now limited folder and when i click it it’s going to jump me to that folder and i’m going to say i want to put it in the folder notebooks and then i’m going to give my notebook a name so i’m going to click in the notebook name field and i’m going to call my notebook project artemis so maybe where i work we are working on a project that’s got a code name of project artemis and i want all of my notes all of the meetings all of the content related to this project to be contained within this notebook so i’ve given my notebook a name and i’m going to say create and this is a really important point you’ll see straight away it’s popped up with a little message that says your notebook has been created would you like to share it with other people and that’s come up because i’ve saved it in a location that is shareable so if i wanted to maybe i know right now that i want to share this with the rest of the project artemis team i could choose invite people now i’m not going to do that at this stage because i want to talk you through that process a bit later on so i’m going to say not now and it creates my notebook and what you’ll see is that my notebook name is now listed just here and as i hover over it gives me a little bit of information in that screen tip so it says i can click to view other notebooks so if you have more than one notebook open if you click just here you’re going to be able to see all of your notebooks listed and you can easily switch between the different notebooks that you’re working in now obviously i only have project artemis open which is why it’s the only one i can see listed here something else you can see when i hover over is you can see the location where i have this notebook saved so onedrive train it now notebooks and it’s telling me that it’s up to date and this is another important thing to note onenote notebooks automatically save so you don’t have to worry about going into file and save you don’t have to press ctrl s as you’re working everything automatically saves and synchronizes and this is particularly important if you’ve saved your notebook to cloud storage like onedrive every change you make will be synchronized every change that anybody else makes to your team notebook if they have access will also be synchronized so all this message is telling me is that all of the changes are up to date so that is basically how you create a notebook from scratch if you wanted to create another one you could just jump back into file go to new and go through exactly the same process select your location first give your notebook a name and then it’s going to open in onenote and it will be listed in your notebooks drop down and we’re going to create a couple of notebooks a bit later on so you can see how you can very easily switch between the two and work in multiple workbooks at the same time now in the next lesson we’re going to delve a bit more into notebook properties i’m going to show you the different things that you can change and i’m also going to show you how you can essentially close a notebook and come out of it when you’re done but for now that is it i will see you in the next module hello everyone welcome back to the course we are down in section two where we are getting started with onenote and in the previous module i showed you how to create a new notebook from scratch and select a location in which to store it so what we’re going to do in this module is i’m just going to show you how you can modify the properties on a notebook and also how you can close a notebook when you’re finished with it so let’s take a look at properties first of all now as we’ve already discovered any notebook that we have open will be listed underneath this drop down and currently i only have project artemis open now if i want to view the properties for this particular notebook if i right click my mouse you’ll see right towards the bottom in this little menu we have a properties option so let’s select it and see what we get now when you go into notebook properties there isn’t a great deal of information that you can change in here but there are some important things that you should be aware of if for example you want to change the display name of your notebook so maybe i want to change this to project alpha project beta something else i can come in here and i can edit the display name and what you’ll see underneath is it says does not affect the actual notebook folder name so what that’s essentially saying is you are merely changing the display name the name that you can see in onenote it doesn’t change the folder name so for example if i just quickly pull up file explorer this is essentially where i have my notebook saved in onedrive in the notebooks folder and you can see here a couple of workbooks that i have within this folder and one of them is project artemis so if i was to change the display name to project beta and click on ok it’s going to change the name here but what it’s not going to do is change the actual folder name within notebooks so that’s a really little important point to be aware of now so we don’t confuse things i’m actually going to go back into my properties and i’m just going to change that name back to project artemis the next property that we can change is the color of the notebook and we have a drop down here which brings up a little palette of muted pastel shades and we can essentially color code our different notebooks it makes them stand out from one another you could even color code notebooks that are maybe related with the same color just as a way of organizing your notebooks in a more visual way so i’m going to select this purple color for this particular notebook underneath that we have the location so it’s telling me the location where my current notebook is stored and if i decide i want to move that somewhere else i can click on change location once again it’s going to open up file explorer and i can choose a different folder to save my notebook into and then finally at the bottom it’s telling me what my default format is so it’s saying that this is a onenote 2010 to 2016 notebook format and the convert to button is grayed out for me so if i was to open a notebook that was in a different format i could choose to convert it to 2010 to 2016 format but at the moment we are all good with how we have our format set so i’m just going to click on ok so now when i click the drop down you can see that my notebook is that purple color so those are the properties that you have for each notebook as i said not a great deal but some important things in there now the final thing i want to talk to you about in this particular module is how to close notebooks so you might have multiple notebooks open and if you’ve finished working in one of them for the day you’re going to want to close down that particular notebook now in most microsoft applications when you want to close something you would jump up to file and there would be a handy little close button in here but you can see with onenote we don’t actually have that so we need to close in a slightly different way again we’re going to click the drop down we’re going to hover the mouse over the notebook that we want to close right click and in here you’ll find a close this notebook option and when i click it it’s going to remove that notebook from the list now i want to stress here you haven’t deleted your notebook it hasn’t disappeared you have literally just closed it down and of course if you want to reopen it you would go back up to file down to open and because this is a notebook that i’ve recently opened the quickest way for me to open this would be to scroll down make sure i’m clicked on recent and then underneath the notebooks tab i should be able to see the last notebook that i had open at the top of this list so i’m going to click project artemis just to re-open this notebook so modifying your notebook properties and closing notebooks very straightforward very simple but very important in the next module i’m going to talk you through the process of deleting a notebook because this is not as easy as it might sound and it’s something that i find confuses people quite a bit because it works a lot different to how other things work in microsoft so i’m gonna grab a coffee jump over to the next lesson and i look forward to you joining me over there hello everyone and welcome back to the course this is still deb and we are still down in section two where we’ve been taking a look at some of the fundamental skills you need to know in order to get started with onenote and in the previous modules i’ve shown you how you can create a notebook from scratch and as is called project artemis and i’ve also shown you how you can modify those notebook properties and we finished off by taking a look at how we can close down any open notebooks once we’re finished using them now the subject that i want to discuss in this particular module is deleting notebooks because i’ve been training onenote for quite a few years now and i find that this is a really common question people get very confused when it comes to deleting because it’s not as straightforward and obvious as you might expect it to be so for example if i said to you how do you think you would delete a notebook the logical assumption is that you might jump into your notebooks list right click on the notebook and you have an option in here to delete the notebook but what you’ll find when you come into this right-click menu is that you actually don’t the only thing you have is close this notebook now whilst that will get rid of the notebook from your notebooks list it hasn’t deleted it it’s just closed it and you can jump back into file and reopen that notebook whenever you like however there will be times where maybe you’ve completed a project and you have no use for the notebook anymore we want to actually delete it and all of its contents so how do we actually delete a notebook this is where it’s really important to know where you have your notebook stored or saved so if i pull up file explorer so here i can see the two notebooks that i have saved into the notebooks folder in onedrive so what do you think i might do here in order to delete this notebook well again the logical assumption as i’ve led you down this path is that you can come into here click on the notebook you want to delete and press the delete key on your keyboard but look what happens i’m going to delete it i’m going to wait a few seconds and you’ll see that it automatically comes back again and this is where i find people have a problem they try to delete it from one drive but it keeps appearing back now the reason why that is happening is because you can see that i’m working within file explorer and i have my onedrive synchronized to file explorer so i can work with my onedrive files without having to log in to the microsoft 365 portal but what happens is my portal synchronizes with my folders in file explorer so as soon as i delete project artemis the synchronization happens onedrive can see the project artemis notebook still in microsoft 365 and so it pulls it back into my folder structure so with all that said how do we actually delete this notebook well we need to log into the online portal so i’m going to minimize file explorer and the first thing i’m going to do is i’m going to close down project artemis because this is the one that we’re going to delete so i’m going to right click and i’m going to say close this notebook what i’m then going to do is jump across to my microsoft 365 portal now i’m already logged in and for those of you that are familiar with using microsoft 365 this should be instantly recognizable and what i want to do is i want to access onedrive from here so i’m going to select the onedrive icon and then i’m going to go to my notebooks folder and this is where i have my onenote notebook saved so what i need to do is select the notebook in this case project artemis and delete it from my portal and you’ll see that when i delete it from here it doesn’t come back again so now if i jump back into file explorer you can see that in my notebooks folder i don’t have that project artemis notebook anymore so essentially it is deleted so this is a really important point to note if you want to delete a notebook that you have saved to cloud storage now i will say that if the notebook that you’ve created is just a local notebook it does work in a slightly different way but we’re going to save that for the next module where we’re going to jump in i’m going to show you how you can create a locally stored notebook and then we’ll look at the difference when it comes to deleting but for the time being that is it i will see you in the next module hello everyone and welcome back to the course in the last module i showed you the process of deleting a notebook that’s been stored into onedrive so what i want to do in this lesson is really just talk a little bit about locally stored notebooks and show you how you can manage those how you can delete them so that you can see the difference between local notebooks and notebooks that are stored in the cloud so let’s jump in and let’s create ourselves a couple of notebooks so we’re going to go up to file down to new and i’m going to recreate one saved into onedrive because we did delete project artemis and i kind of want to use that one so let’s select onedrive i’m going to select the folder of notebooks and i’m just going to call it the same thing let’s call it project artemis just to recreate that notebook and click on create now because i’m saving to a shareable location it’s asking me if i want to invite people i’m going to say not now because that’s something i’m going to do later and there i have my notebook opened again and of course we’ve already seen we can right click and maybe i want to go into the properties and i’m going to change the color to blue and click on ok so what i’m going to do next is i’m going to create another notebook but this time i’m going to save it to my local drives not in onedrive so back up to file down to new and this time i’m going to browse for a location to save now what i’m looking for here is a location that doesn’t synchronize and these days with onenote if you have it installed on your pc even your desktop will synchronize so i’m going to select a folder that i know doesn’t synchronize which is the downloads folder now i know this is an extremely strange folder to save a notebook into but as i said i just want one that i know for sure doesn’t synchronize at all so i’m going to give my notebook a name i’m going to call it my personal notebook and click on create now did you notice the difference there it didn’t ask me if i wanted to invite people to my notebook and that’s because onenote has recognized that this is a locally saved notebook and so it’s not shareable another thing you’ll notice is that if i click this drop down you can now see both of my notebooks in here now if i just make a quick change so i’m going to right click and i’m going to say properties and let’s just change the color of the folder again and click on ok notice this little sinking icon that comes up it was pretty quick so you may have missed it let me do it one more time i’m going to right click go to properties i’m just going to change the color of the notebook look for this icon when i click on ok can you see it just there that tells me that the notebook is synchronizing to cloud storage now when it comes to locally saved notebooks it doesn’t matter how many changes you make you’re never going to get that icon because it’s just saving to your local drive it doesn’t have to synchronize with cloud storage so if you’re wondering what that little sync icon is that appears every now and again when you’re working in a notebook that’s been saved to the cloud that’s what it’s doing it’s just updating any changes that you’ve made or any changes that other people have made to the notebook with the copy in the cloud now when it comes to local notebooks you can right click and you can change the properties in exactly the same way so i can change the color of the icon the location and the display name as well so maybe i want to remove the word notebook let’s just delete that out as it’s a bit of overkill and just call it my personal click on ok and there we go and i can very easily switch between my two notebooks now when it comes to deleting locally stored notebooks it works in a slightly different way now i still can’t delete it from within one note so if i right click i don’t have a delete option so what i need to do is open up file explorer again and navigate to the folder where i have this notebook stored so i’ve stored this notebook in the downloads folder you can see it there sitting at the top so if i want to delete it i can actually just delete it directly from here because i don’t need to jump into cloud storage because it’s just saved locally and because there’s no synchronization happening it’s not going to keep reappearing however the first thing i’m going to want to do is close down this notebook i can then jump into the folder click on the notebook press delete and that notebook is essentially deleted so the process is a little bit shorter a little bit easier when you’re deleting local notebooks now in the next module we’re gonna start to actually expand on our notebook by adding in sections and pages so i’m looking forward to it i hope you are too i’m gonna head over there now and i look forward to seeing you so so far in this course we’ve been taking a look at some of the more admin tasks that you might wish to do within onenote such as closing notebooks creating new notebooks and also the process for deleting notebooks it’s now time to move on to something a little bit more interesting and that is to start to build our notebook with content now before we can start adding content in we need to understand the structure of a notebook and that means talking about sections and pages so currently i’m in the project artemis notebook and you can see at the top i have a tab that says new section one then if you cast your eyes over to the right hand side you can see i have add page at the top here and then something that says untitled page now untitled page is currently where i’m clicked now i’m going to speak a little bit more about pages in the next couple of modules but for now we’re going to focus on sections and really organizing our notebook now the way i like to think about this is i like to imagine a book project artemis is the book title and then within that book i might have part one which would be the section and then i would have the different chapters which might be the different pages so these are kind of like dividers within your notebook and within each section you can have numerous different pages now when it comes to sections there are lots of different things that you can do with them so let’s start out by running through some of the basics so currently i’m clicked on new section one and if i right click my mouse you’ll see that i get that contextual menu come up which has lots of different things i can do with this particular section so the first thing i have in this menu is the rename option now obviously most of the time you’re not going to want to keep that tab as new section one you’re going to want to give it a more meaningful name so i’m going to select rename and i’m just going to over type what i have on the screen and i’m going to call this tab meetings now what i can do here is i can either hit the enter key on my keyboard or i can just click away in order to set that so that is my first section now i want to have lots of other different sections within this notebook to store different types of information so i’m going to add another section in and there’s a couple of ways that you can do this the most easiest and probably the most obvious to everybody watching this lesson is that we have a little plus sign and when we hover over it it says create new section that’s going to give me another tab and i can now type the name of that tab and this one is going to be called corsets and hit enter now the other way that i can add a new section is if i right click on any one of the tabs you’ll see that i have a new section option down here as well which is basically going to do exactly the same thing so for this one i’m going to call this offices and hit enter and i’m going to carry on just adding a couple more sections into this notebook so let’s click the plus and i’m going to call this one travel hit enter click the plus again and we’re going to call this one costs and hit enter so very quickly i’ve been able to add into my notebook all of these different tabs and i can then just click on them to switch to those different sections and what you’ll also notice is the section tabs are color coded so if you want to keep them all different colors that’s absolutely fine however if you have sections that maybe relate to each other a nice way of just visually indicating that to whoever is looking at the notebook is to make those tabs the same color so maybe both offices and travel are related and i want to make them both orange what i can do is click on that travel section right click my mouse and right at the bottom of the contextual menu i have a section color option so i might want to change this to orange as well and so visually i’ve now created a link between those two different sections now of course when you have a whole bunch of sections added into your notebook there might come a time where you want to reorder them or rearrange them and again that’s very simple to do if you want to move a section all you need to do is grab that particular section so let’s say the courses section click your mouse drag and you’ll see as i drag back and forth across the section tabs i’m getting that little black arrow and that’s indicating to me where that section is going to be dropped when i let go of my mouse so i want this to be the first tab in this particular notebook so i’m going to let go of my mouse and it moves that tab across another way that i can move section tabs is to utilize that right click menu also so for example if i take this meetings tab and right click my mouse within that right click menu you’ll see that we have a move or copy option so if i select that i can now choose where i want to move this particular tab to and what it’s showing here are all of these sections that are currently in my notebook and all i need to do is select the one that i want to move this particular section after so i’m going to say i want meetings to move after the travel section so i’m going to select travel and click move and it’s going to move that across similarly if i right click my mouse and just jump back into there i might want to copy a section instead of moving it so if i want to copy this meeting section and i want that copy to be placed after the cost section i’m going to select costs and then click copy at the bottom and it’s going to give me a new tab that’s called meetings 2. i can then right click go in and rename that to something else so we’re going to call this one schedule like so and you’ll see that because i copied it it takes on the same tab color as that particular section now in this case i don’t want these two to be the same color so i’m going to right click section color and i’m going to make this a purple color and of course i’m sure you get the idea now but if you want to delete a particular section you can right click and you have a delete option in here now it’s worth noting and you’ll see this a bit later on when we start talking about pages when you delete a section it’s going to delete all of the pages within that section as well so just bear that in mind before you actually execute this particular task but more about that later so that is the basics of adding new sections and a few tips and tricks there when it comes to managing them in the next lesson i’m going to talk to you about section groups so i’m going to head over there now and i look forward to you joining me hello everyone and welcome back to the course in the previous module i introduced you to the concept of sections and we took a look at some of the things that you can do to add new sections and also manage them so we’re going to kind of follow on from that in this particular module and i’m going to talk to you about section groups and just show you what they are and how you can use them now the first thing i’m going to do in here is i’m actually going to delete one of these sections that i’ve created so i’m going to delete this courses section because what i’m going to do is i’m going to make courses a section group so i’m going to right click and i’m going to say delete and i’m getting a message here saying are you sure you want to move this section to deleted notes so i’m going to say yes now that’s actually an important point to know when you do delete sections or pages or anything from your notebooks they don’t disappear entirely they go into what we call the notebook recycle bin i’m going to talk a little bit more about that later on in the course so just keep that in your memory for a bit later on so now what i’m going to do is i’m going to create a section group and this is really just another way of organizing your notebooks and this is particularly good if you have a lot of information in any one notebook now to create a section group it’s pretty simple all you need to do is right click on any of the tabs and you can see you have an option here for new section group and what that does is it gives me another little heading up here that currently says news section group and you can see the icon next to it has all of these different tabs so that gives you an idea as to what we’re doing here this is a way of grouping different sections together so i’m going to call this section group courses and hit enter what i’m going to do within here is create sections within this section group so if i right click i’m going to say new section and what you’ll notice is something a bit strange it adds it as if it’s just another new section it doesn’t necessarily fall directly underneath where we’ve created the new section group so i’m going to go ahead and create my sections that i want to be part of my section group now this whole project artemis is about the rollout of office 365 across all of my company’s global offices and part of that rollout program is going to be training and we want to retrain everyone on the applications within office 365 or microsoft 365 as it’s now known so i’m going to have a section for each of the courses that are going to be offered so the first section is going to be called word i’m going to create another new section called excel another one called powerpoint we’re going to have one for one drive and i could carry on going now obviously this is just a demo so i’m gonna stop there but you would add as many sections as you needed now once you’ve added in your sections if you want to group them together underneath this courses section group all you need to do is right click so let’s right click on this first section tab i’m going to say move or copy i’m going to select the section group which is courses and then i’m going to say move and you’ll see immediately it jumps me from my main notebook into this kind of sub group so project artemis courses section group and there is my section so if i want to jump back i just click that green arrow so if i take this excel section i’m going to click i’m going to drag over and hover my mouse on top of courses and you’ll see it jumps me across i can let go and it moves that section now unfortunately there is currently no way in one note to make a multiple selection so you can’t select multiple sections and then move them all in one go unfortunately you have to do them all individually so i’m going to do the last two let’s do powerpoint i’m going to drag and drop and then the final one i’m going to right click i’m going to say move or copy select courses and click on move so now i have these essentially sectioned off from the main bulk of my notebook and i have my courses section group just there so if you have a particular section that has lots of different subsections then this is a great way of organizing your notebook so we’re starting to get some kind of structure to our notebook now we’ve got a notebook ready we’ve got all of our sections we’ve got a little section group on the end there now we want to start adding pages and content and that’s exactly what we’re going to do in the next module so i’m going to head over there and i look forward to you joining me hi guys and welcome back to the course this is still deb and we are heading towards the end of section two and over the course of this section we’ve really got to grips with some of the basics of working in onenote and in the last couple of modules i’ve shown you how you can add sections into your notebooks and also section groups it’s now time to start adding pages because there’s a couple of things that you need to be aware of when you’re doing this so as i mentioned within each section you can have different pages and each of those pages will contain content so let’s first walk through the process of adding pages to sections so currently i’m clicked on this offices section now what i want to have here is i want to have maybe an overview of all of the different offices which we’re rolling out microsoft 365 to and then i might want to have a specific page that lists out each office individually with bits of information that are particularly important to that office now if you cast your eyes over to the right hand side of the screen you’ll see that you have this kind of orange bar running down the side and this is where you basically create all of your pages for your sections and onenote will automatically create a page called untitled when you add a new section and that page is currently what i’m clicked on within the offices section now currently it’s called untitled which isn’t particularly meaningful so i’m probably going to want to go in and rename this page so it’s easy for me to identify so my first page in this section is just going to be called overview so i’ve clicked my mouse just above where we have the date and time and i’ve typed in the word overview and you’ll see as soon as i do that over on the right hand side the page is now renamed so i’m going to go through and i’m going to add a few more pages and we do that by clicking on the add page link at the top of that right hand pane so let’s click on add page you’ll see automatically i get another untitled page and i can now type a title for this particular page so this one is going to be called europe i’m going to add another page called north america another page for asia another page for africa and then one final page for australia and as we move through this course i’m going to be adding information onto these pages so adding pages in itself is a very simple and straightforward process but what you might not know is that you can also add sub pages so for example underneath each of these pages which i’ve just created i might want to have sub pages for each of these specific office locations in each of these regions so what i’m going to do is i’m going to add a page and you’ll see it adds it to the bottom i’m going to call this one london i’m going to add another page i’m going to call it paris i’m going to add another page and let’s call this new york and i’m going to add two pages for each of the regions and we’ll do bangkok and we’ll say durban and finally for australia we will have sydney and melbourne so you can see that now i have quite a collection of pages and at the moment they’re not really organized as i want them to be so the first thing i’m going to want to do is i’m going to want to move the pages i’ve just created underneath their relevant locations so for example we’ve got london and that needs to go underneath europe so all i need to do to move a page is click drag and you’ll see i get that line let go and it’s going to move that page i’m going to grab paris and we’re going to do the same thing we’re going to move that up now of course when i’m moving these i can go to the right click menu and move or copy but for me by far the quickest way of doing it is just simply to drag and drop them so i’m going to move new york and chicago underneath north america and for pages you can actually move multiple pages in one go so i want to move shanghai and if i hold down my control key i can also select bangkok and then i can move both of those underneath asia so i’m going to do the same for durban and johannesburg hold down control drag and drop and then finally at the bottom we have australia with sydney and melbourne so these look slightly better but the structure still isn’t quite there because essentially these city pages that i’ve added are subpages of the continent so i want to indicate that these are in fact sub pages and again there’s a couple of different ways that we can do this the first thing i can do is if i click on london if i click my mouse and just drag to the right very slightly you can see i can indent it so this is a sub page so i’m going to indent it once and i could do the same for paris click drag once and that essentially makes london and paris subpages of europe and the structure is now reflecting that now i can do this a slightly different way so let’s select new york hold down control and also select chicago if i right click i can say make subpage and it’s going to move both of those in i’m going to select shanghai bangkok durban johannesburg sydney and melbourne and i’ve done that again simply by holding down the control key as i’m clicking right click make subpage and it’s going to move all of those in in one go so right away i now have a much better structure it’s a lot easier for me to see what’s going on here and as you can imagine you can have sub pages of sub pages as well so if i just show you a quick example if i add another page and let’s call this sync kilda which is a very specific area in melbourne what i might want to do is make the syncilda page a sub page of melbourne so again i can click on it i can drag once twice to make that a sub page of a sub page and you can carry on going making whatever structure it is that you need and of course if we right click we now have that contextual menu come up so everything in here is related to pages as opposed to sections or anything else you can promote the sub page so that’s essentially pulling it back up a level or you can collapse all sub pages for whichever one you’re clicked on so for me that was australia it’s collapsed them all up i can then click that drop down arrow to bring those back again i can right click i can move or copy i can add a new page from here as well and you can also see the keyboard shortcuts in there now i’m actually going to delete this page so let’s select delete to bring me back to how we were so i’ve got a pretty good outline or structure going on on this offices section and of course i can go to each of these sections and start adding in different pages you don’t necessarily have to do that before you add content you can definitely do it as you go but for me on this particular section it works best if i set them up beforehand so that’s how you can very simply add pages to a section and also make subpages and that draws this section to a close in section three this is where the fun begins we’re going to start adding all different types of content into a notebook so you can get a really good feel for the application and what it can do so i’m really looking forward to this section i’m gonna head across there now and i look forward to you joining me hi guys and welcome back to the course now as i mentioned in the introduction at the end of each section i’m going to also throw in a module using onenote for windows 10 because this is something that is available for free and comes automatically installed for anybody who has windows 10 on their pc or laptop so in general what we tend to find is that if somebody doesn’t have a microsoft subscription necessarily they can still utilize onenote but the windows 10 version so in order to cater for those people who are using this version i’m just going to do a module at the end of each section just recapping the main points in that particular section so let’s get started with our first look at onenote for windows 10. so if you do have a windows 10 device you’ll probably find that you already have onenote pre-installed so i’m going to jump down to search and i’m going to type in onenote and you’ll see the first one that comes up is onenote for windows 10. so let’s click to open this app and take a look at the differences so immediately what you’ll notice is that the look and feel is completely different to one note for desktop so first of all let’s take a quick look at the interface now we still have essentially a ribbon structure but our ribbons look slightly different they’re a bit more compact we have a home ribbon that has all of our basic formatting options on it an insert ribbon if we want to do things like insert tables files pictures a draw ribbon for making annotations and inserting shapes a view ribbon for doing things like zooming in and out changing the page color adding raw lines so on and so forth and then finally we have a help ribbon that’s going to allow us to access help on demand if we need it and then all the way over in the right hand corner we have some icons so this first icon here allows me to open a feed so this is basically going to allow me to see a feed of all activity that’s going on in my onenote notebook i then have this little light bulb icon which is basically my search so this is the tell me what you want me to do pain i have a notifications area where i can see exactly what’s going on in my notebooks i have a share button that’s currently grayed out i can choose to enter full screen mode and then i have three dots in the top corner or ellipses that’s going to allow me to access my settings now when it comes to actually viewing my notebooks if you cast your eyes over to the left hand side this first icon just here is the show navigation button so if i click this this is going to open up a pane where i can view all of my notebooks now i haven’t created a new notebook yet so that’s why there’s nothing in there but when i do this is where you’ll find them and this is how you can switch between your notebooks so let’s start out by doing exactly that and there’s a couple of different ways that you can create notebooks in onenote for windows 10. if you take a look in the big empty space in the middle where it says start taking notes it says tap or click here to create a new notebook you can also open one of your existing notebooks from the notebooks list so that’s an important point if i click the drop down where it says notebooks and then click on more notebooks it’s going to allow me to open an existing notebook that i have saved off so if i want to go in and open up project artemis or personal i can do that simply by clicking on that notebook and then opening it now in this case i actually want to create a brand new notebook so i could click somewhere in this center pane select a name for my notebook and then click create notebook alternatively i could right click up where it says notebooks and select new notebook or if i click on notebooks right at the bottom i have a plus symbol that says add notebook so i’m going to call this notebook project sierra i’m going to select an account and click on create notebook so now i have my new notebook and it’s created a new section with a default name and also an untitled page for that section now of course i’m going to want to rename this particular section so i can right click my mouse to pull up the contextual menu and say rename section now i’m going to call this to-do list and click away to set that and then i can name my page so let’s say today’s list what you’ll notice is right at the bottom if you want to start adding more sections and more pages you can so i’m going to click add page tomorrow’s list add page next week’s list so on and so forth and i can do the same with sections so let’s say add section things to remember and then maybe i want to name this page emails so on and so forth so pretty easy to create notebooks sections and pages and of course if you click that drop down this is where you’re going to see a list of your notebooks and if i had more than one i can easily switch between them from up here if i right click on this notebook you can see that i have other options that are similar to the desktop version for example i can change the notebook color to something that’s a bit brighter so let’s say pink and another thing i can do here is if i want to close this notebook and essentially remove it from my list if i right click i have an option to close the notebook from here now when it comes to things like sorting or moving rearranging sections and pages around again the process is very simple it’s just drag and drop so if i want to reorder these pages for example if i want to move tomorrow’s list above today’s list i can click drag just to reorder those the same thing goes for sections so i can click on things to remember and drag it above to-do list just to reorder those items i also have a sort button over here so i can sort these pages in alphabetical order by day created or date modified now you can also create sub pages in this version of onenote so let me add in a couple more pages i’m going to call this one monday let’s add another one and call it tuesday and what i want to do is make monday and tuesday subpages of next week’s list so what i can do here is select both monday and tuesday right click my mouse to pull up the contextual menu and you see all of the different options you have in there related to pages so i can delete my pages i can cut copy and paste i can move them to other sections and i can also make these two selected pages sub pages so let’s click that option you can see that they indent very slightly and next week’s list is now a collapsible and expandable menu item and of course if i want to go in and right click and say move this particular page i can then select where i want to move it to so let’s say things to remember and i can say move it’s going to move that across and now when i click on things to remember i can see that page sitting there so in this case it’s really important where you’re clicked when you right click if i right click on a section i get a contextual menu full of options related to that section whereas if i right click on a page i get a completely different contextual menu that allows me to select options related to managing this particular page now what i’m going to do here is select tuesday right click and say delete page and if at any point when you’re working in onenote for windows 10 you want to get rid of this navigation pane to give yourself a little bit more room if you click on the hide navigation icon it’s going to minimize that down and now you have loads of room from which to type your notes so that is it that is all the information that you need in order to get started working in onenote for windows 10. hello everyone and welcome back to the course we’re down to section three now and in this section we’re going to explore all the different tools that you have available for adding content into your notebook and really this is what a notebook is all about of course once we’ve created our sections and our pages we’re going to start to want to add content to each of those pages and in onenote there are so many different types of content that you can add in so that what you end up with in the end is a really nice functional informative and interesting way of storing notes and throughout most of this section we’re going to be focusing on the insert tab up here because this is where you’ll find all the different types of content you can insert into your notebook now before we get on to some of the more interesting and exciting aspects of onenote we’re going to start out with the basics and that is adding a text note onto a page now that might seem fairly straightforward i have my cursor flashing flush with that left hand margin and as you could probably imagine i can start typing a note and that is very true now when you type a text note in onenote it does work a little bit differently to something like word in word when we have a document open we start typing from the left hand margin and work across the page and unless we use things like tabs or maybe indents we’re pretty much limited to starting our typing from the left hand side of the page now one note works in a slightly different way because what you can see is i can literally click my mouse anywhere on this page my cursor starts flashing and i can start typing so it has much more of a scrapbook like quality so what i’m going to do is i am going to click over towards the left hand margin and i’m going to start to type my first note on the overview page so this is my first note just a little bit of information about the rollout and what you’ll see is that when you type in a text note it kind of puts it in this little placeholder and this is kind of like a movable text box in a way you can see that if i hover over the gray bar that runs across the top i get a crosshair it just means i can pick this note up and i can literally drag and drop it anywhere on the page that i like so it is a lot more flexible than when you’re typing text directly into a word document what you’ll also notice is that on the end here i have these two arrows and that just allows me to resize this placeholder so i can drag it in if i want to make it smaller and drag it out if i want to make it wider and as you would imagine if i right click my mouse on this grey bar i get a contextual menu that has options in it relating specifically to this particular placeholder and the text contained within it now if i want to edit any of this text i just click back in the placeholder and i’m going to add a little bit of a title here i’m going to hit enter and let’s call this rollout dates and of course i can treat this like any other text across all of the microsoft applications and i can apply formatting if we jump up to the home tab this is where you’ll find all of your text formatting options so it might be that i want to change the font style of all of this text now what i can do there is because the text is contained within one placeholder i can just select that placeholder i can jump up and i can change this to something else so i’m going to do my favorite font so go ui hit enter and it’s going to change that and if i want to make this heading stand out a little bit i can maybe make it slightly bigger so let’s make that 12. i might want to make it bold i can change the color i can do all different kinds of things and if you’ve used any of the other microsoft applications you’ll know that this is fairly standard when it comes to font formatting now i’m going to add a little bit more text into here so i’m going to press enter a couple of times now i’m going to add some bulleted text so again up to the home tab into that basic text group and we’re going to utilize our bullets and i can add my bulleted text much like i would in any other application now everything that i’ve typed so far has been contained within this one placeholder you don’t have to carry on typing absolutely everything within the same placeholder you could click somewhere else and start to type in some more text like so and then i’m going to add some more bullet points in like so now one thing you’ll notice here is that as soon as i started typing in a different placeholder it’s switched back to the default font which for me is calibri so if you want to keep things consistent then you’ll probably have to go in and change that font to match the rest of the font in this particular document and i can then pick that up and i can drag it underneath so what i’m trying to say here is don’t think that you’re limited to just always typing in one placeholder you can have multiple going on on the same page another thing you can also incorporate into your text notes is that you can utilize styles and you’ll find those on the home tab in the styles group and this can sometimes make it a little bit easier to achieve a level of consistency when it comes to the headings that you’re using in your notebooks so for example instead of going through and manually formatting the headings like i did with rollout dates i could select the heading and utilize a style instead which has pre-formatting already applied so i could say heading 1 to change that and i know that every time i add a heading 1 it’s going to look exactly the same throughout the entire notebook so don’t forget about those you have headings 1 to 6 and you also have other styles in here for page title quotes anything else that you want to add in now the final thing i’m going to do in my text notes is i’m just going to highlight the dates that this rollout is going to start and end just so it’s super clear to everybody who is looking at this notebook so i’m going to highlight january the 1st 2021 and i’m actually going to apply some highlighting like so now i want to apply the same highlighting to the 31st of july 2021 so i could repeat the same process alternatively i could utilize the format painter so i’m going to highlight january the 1st 2021 i’m going to go up to the home ribbon and select format painter let go and it’s going to apply that highlight for me so format painter is a great tool if you just want to copy formatting from one piece of text to another it can save you a lot of time particularly if you have a lot of manual formatting applied to a specific piece of text or paragraph and we’re going to be utilizing format painter quite a lot as we work our way through the course so for the time being that is the basics of adding in a text note into your notebook page over the next few modules we’re going to move into adding all different types of content in and we’re going to start out by taking clippings from web pages and pulling those into our notebook so i’m going to head over to the next module now and i look forward to seeing you there hello everyone and welcome back to the course we’re down in section 3 where we’re talking about adding content to onenote and in the previous lesson i showed you the very simple task of adding text notes to your onenote pages so we’re going to move up a gear now and we’re going to start to add content from other sources now there are many different ways that you can do this in one note and we are going to explore all of them over the balance of this section but i want to start out by introducing you to a little tool that you can install that’s going to make your life a lot easier in certain respects and that is the send to onenote tool now you won’t find this when you’re actually working in onenote there is no button on any of the ribbons called send to onenote this is a little app that you can install which makes it super easy for you to send things like excel spreadsheets or word documents or even emails directly to a specific page in onenote so i’m going to show you first of all how you can install the app it’s very very simple and then i’m going to show you how to use it so the first thing you’re going to want to do if you don’t have this app installed is just open up your preferred web browser so for me that is microsoft edge and then search for send to onenote app and hit enter and the first link you’re going to get takes you to the microsoft web page and you can see there it is send to onenote we have a little description underneath so it says send to onenote lets you print from any app to a onenote page once it’s in onenote you can access it from any device even if you’re offline so this is also great if you have maybe something like a pdf document and you want to bring that information into your onenote page so it’s viewable to everyone so what you do from here is you can see over on the right hand side is actually a free app which is always good i’m going to click on get and that’s going to ask me to open the microsoft store so it’s jumping me across to the application within the microsoft store and from here i can install it now the first thing you’ll notice is that i actually already have this product installed if you don’t what you’ll see here is an install button where i currently have wishlist so all you need to do is click install it takes a few seconds for that to download and that is pretty much it once you’ve done that you are good to go so let’s take a look at how we would then use it so i’ve jumped across to outlook just to show you an example of how you can utilize send to onenote once you’ve downloaded and installed the app and you might have to restart your applications in order for this to show but for example on the home ribbon in outlook you can see in the move group i now have this little icon here send to onenote and that’s going to allow me to directly send any email message that i have selected to a specific page in my onenote notebook so i can see here that i have an email which is all about team leader assignments for this rollout project and it has a file attachment there as well so this is important information that everybody’s going to need to know so this would be great content for me to add into my notebook so i’m going to click the onenote button and you can see what i get so underneath all notebooks i have project artemis now i’m going to click on the plus to expand that out and you can then see all of my different sections and tabs now if i have a specific page in onenote that i want to send content to i can expand for example the offices section and see all of the pages that i have underneath there so what i might decide to do is select the overview page click on ok and there we go you can see that i now have that email added into my onenote page it’s telling me the subject who it’s from who it’s to the date it was sent and i also have the attachment just here so what i can do is double click on this attachment and it’s going to open it up and the cool thing about this is if any changes are made to this particular spreadsheet those are going to update because you’re essentially you’ve just created a link to the original spreadsheet now it might be that now that i have this email on the overview page i think to myself actually you know what this needs to go on a different page so what i might want to do is create a new section let’s click on plus and i’m going to say important emails and i’m going to call this page team assignments and what i’m going to do is i’m simply going to move that content across to this new page now i can do that by selecting the placeholder and the simplest way of doing this is to do a cut and paste so i can either jump up to my home ribbon and select cut from there or i can utilize the keyboard shortcut of control x i’m going to jump across to important emails and the team assignments page i can do ctrl v to paste or select my paste button just to paste that in so a nice simple way of adding content using that send to onenote tool and just to show you another example of how you can utilize this if i had this information in a word document as opposed to an email i could also send this directly to onenote as well so any content you have in spreadsheets documents powerpoint presentations once you’ve installed this app when you go to the file area and go down to print underneath printer you can select onenote desktop and then when you click on print you’re going to get the same thing you need to select a location in which to print this piece of content to so i’m going to expand offices again i’m going to select overview and click on ok and you can see exactly what it does there it’s going to pull that information in now one of the drawbacks of this which you can see immediately is that it’s brought it in with a load of white space at the bottom so everything else gets pushed down underneath now i have scoured the internet trying to find a way to get around this and there doesn’t appear to be any particular method of cropping out all of that white space so just think about that before you utilize it to send word documents and excel spreadsheets to your notebook but for now that is how you utilize send to onenote in the next lesson i’m going to show you how you can use onenote’s clipping tool so i’m going to head over there now and i look forward to you joining me hello guys and gals and welcome back to the course we’re down in section three where we’ve been taking a look at how we can add different types of content to our onenote notebook and in the previous module we saw how we could download and install the send to onenote app in order to send documents different files pdf content to onenote now we’re going to stay along similar lines and when i say similar lines i just mean that what i’m going to show you next is also an app that you have to install and that is the onenote clipper now onenote clipper is pretty much the same as any other clipping utility that you might find in microsoft applications most of the applications these days contain some kind of screen clipping tool which makes it super easy for you to grab content off of different applications or maybe even web browsers and pull that into whichever application you happen to be working in now the cool thing with onenote is that there is a specific clipper extension that you can add into your browser to make clipping things off the web super easy to pull into a specific page in onenote so what i’m going to do in this module is to show you where you go to install the onenote clipper and then we’ll do a quick demonstration so the first thing you need to do is open up a web browser of your choice and for me i’m using microsoft edge but you could be using chrome firefox safari whatever it is that you choose now depending on what your web browser of choice is will depend what you search for when looking to install the onenote clipper so for me because i have edge i would search for onenote clipper app edge if you’re using chrome you might want to type in onenote clipper app chrome so on and so forth just to make sure that you get the correct download so i’m going to click on search and i’m going to click on this link just here which is going to jump me across to the microsoft store now what you’ll see here is the web clipper app and because i’ve already installed this i only have a remove button if this is the first time that you’re using this then you’ll have an install button just here so you just need to click it run through the process again it just takes a few seconds it’s a very small little app and once you’ve installed it you should then see a button in your web browser in the toolbar running across the top that says clip to onenote and you can see mine just there so once you have it installed let’s take a look at how you can use it so i’ve just jumped across to the microsoft 365 homepage and this is a web page that just gives me some information about microsoft 365 and the different subscription plans so maybe i want to add into my document some information related to the business plans for microsoft 365. so i’m going to scroll down and see if anything takes my fancy and i can see here we have some information relating to the costs of subscriptions so this might be something that i want to add into my rollout plan for when we’re trying to work out our budget so what i can do is i can clip this information and send it directly to a page in onenote and i’m going to do that by clicking on my clip to onenote tool now if this is the first time that you’re using it it’s going to ask you to sign in with a microsoft account now once you’ve signed in you’re going to have a few different options when it comes to clipping and by default it’s going to clip a full page so if i wanted to send everything on this page to onenote that is my default option now in this particular case i don’t want to send the full page i just want to select a region so let’s select region and you’ll see it says drag and release to capture a screenshot the other thing you’ll notice is that the page background has kind of faded out very slightly and my cursor has changed to a crosshair so this means that i can just click and drag over the region that i want to clip and you can see it adds it to this clipboard ready to send to onenote now if i have lots of different things that i want to clip off of a certain web page then i can just select to add another region and then scroll through and find the next piece of information that i like to clip so let’s say for example i want to add in this i’m going to select it and it’s added that to this clipboard as well and i could carry on going collecting different pieces of content now once i’m finished and i want to send these to my page in onenote i then need to select the location so if i click this drop down you’ll see it’s going to show any onenote notebooks that i have and the one that we’re working in is project artemis so i’m going to click to expand and then i can see all of my different sections now with this you can’t select a specific page you can only select a specific section so i’m going to select offices and i’m going to say clip it goes away it clips those regions it tells me it’s been successful and i can either choose to view in one note or i can just pull it up from my taskbar and what you’ll then see is if you look at all of the pages for this particular section right at the bottom i have a new page and when i click on it it’s labeled it microsoft 365 for business and there are my clips and another really useful thing that it does is it gives you a direct link back to the page where these clips came from so if you essentially want to view the source or maybe read more information you have the link there you can simply click on it and it’s going to jump you back to that specific page now of course because you weren’t able to select a page in your notebook to send this to you might want to do some rearranging at this point you might want to copy and paste this information into a different section so i’m going to select this entire placeholder simply by clicking on it and i’m going to do a simple cut from the home ribbon i’m going to go to the overview page i’m going to click my mouse at the bottom and i’m going to say paste and that then pastes that content in i can resize it to make it a bit neater but i essentially have my nicely clipped content with a link back to the original document of course what i would then need to do would be to go in and delete that temporary page so over in my pages list i’m going to select it right click and i’m going to say delete just to get rid of that so very simple and very straightforward to utilize that clipping utility in the next module i’m going to show you how you can add pictures and video to your onenote notebooks so i’m excited i hope you are too please join me in the next module for that hello everyone and welcome back to the course we’re down in section 3 where we’re talking about adding content to our onenote notebooks and in the previous module i showed you how you can utilize the onenote clipper app in order to clip information content from the web and pull it through into onenote so now what i want to do over the course of the next few modules is show you how to add pictures video and different types of content into your notebooks so for this we’re going to need to be on the insert tab and we’re going to focus on this images group just here now the first thing that we have in images is a screen clipping utility now you might be thinking to yourself well why on earth would i need that you’ve just shown me how to use the onenote clipper well the onenote clipper is an installation for your browser so essentially it only really allows you to clip content from the web now the screen clipping utility that you have available within onenote allows you to clip anything that you have open on your pc so maybe you want to clip something from a pdf document or maybe an excel spreadsheet or from a powerpoint presentation pretty much anything that you can open on your pc you can clip using the screen clipping utility within onenote and you can see as i hover over it we get the screen tip that tells us what this is going to do so it’s going to allow us to take a snapshot of parts of your screen and add it to the page it says onenote will hide while you capture web pages documents or anything else and one interesting point to note that we’re going to get onto a little bit later when we cover searching is that onenote can search for text in screen clippings and that’s a really cool little feature if you clip something so maybe a paragraph of text you can make it searchable but more on that specific aspect a bit later on let’s concentrate on utilizing this screen clipping utility now what i’ve done here is i’m still in the offices section but i’m clicked on the london page and i’ve added a text note that gives the address of the london office now what i might also want to do here is maybe add in a map that shows where the office is located so i’ve opened up google maps and i’ve navigated to the address of the office and maybe what i want to do is take a screen clipping of a certain section of this map now because this is in a web browser i definitely could utilize my clip to onenote utility but i’m going to do this a slightly different way i’m going to utilize the screen clipping option now one of the things that you have to be careful of here is that whatever it is that you want to clip needs to be open directly behind onenote because what happens is as soon as you click on screen clipping it minimizes one note and allows you to clip whatever it finds behind it so if you want to clip a section from a word document you need to make sure that that is directly behind onenote so a way that i do this is i want to clip this so i want to have it as the last thing open and then i’m going to open up onenote on top of it so let’s click on screen clipping you’ll see it minimizes down and shows what’s directly behind it my screen has kind of faded away and i have my cursor as a crosshair so i’m going to clip a certain section of this particular map and pull it through to onenote so let’s just drag a big region over here and i can see rope maker street in the middle let go and like magic it pulls it directly into my page what you’ll also see when you take a screen clipping in this way is that you have underneath the date and time that this screen clipping was taken now if you don’t want this screen clipping information you can delete it out an easy way of doing that is as i hover over this text you’ll see i get this little arrow or tab at the side if i click on that it’s going to highlight that text and i can just press the delete key to get rid of it i can of course then click on the image and i can resize it if it’s a little bit too big and as i mentioned at the beginning if i right click on this image i can choose to make the text in the image searchable now i’m not going to do that right now because we’re going to do that a bit later on but just hold that piece of information in your minds until we get to that section let’s do another screen clipping but this time of something that’s not on the web now earlier i showed you how you can send a word document to your page in onenote utilizing the send to onenote tool under file print but if you remember when we do it that way we get a lot of white space in the bottom so what i could do instead is use the screen clipping utility just to clip out that part of the word document so again i need to make sure that i have the word document open directly behind onenote i’m going to jump to screen clipping it minimizes down and i can then just clip this specific area and pull that through so you can see that’s a much neater way i don’t have loads of blank space at the bottom and once again i can resize that as necessary so screen clipping is a tool that i use all the time in onenote just to grab different pieces of content i find it a lot quicker and a lot easier than other options and if i’m adding content where i’m not too concerned about it being updated dynamically then screen clipping is just a great way to get information into a page in the next module we’re going to start adding some life to our pages by adding pictures so please join me for that hi guys and welcome back to the course this is still deb and we are still down in section three where we’re looking at the different methods that you can use to add different types of content into your onenote notebooks and so far we’ve seen how we can add text notes we’ve seen how we can add screen clippings and now i want to show you how you can insert pictures into your pages so once again for this we’re going to be working predominantly on that insert ribbon and we’re sticking within this images group now you’ll see within here we have two options we have pictures and we also have online pictures so if you have a particular image that you want to add into your notebook and you have that image already stored off locally maybe into your my pictures folder then you would use this option just here however if you want to browse online for a picture to use you could do that through the online pictures option and i’m going to show you an example of both of these so let’s start out with pictures that i have already saved off so currently i am clicked on the europe page within the offices section and what i have on this page is just some suggested activities for free time in both of the european office locations so london and paris so if this is a rollout project we’re maybe sending trainers to these different offices around the world and those trainers might have to stay there for a couple of weeks they’re going to have some free time we want to give them some ideas of things they can do whilst they’re there and in order to illustrate that point make it a little bit more interesting we’re going to add some pictures in so you can see here i have free time suggested activities and i’ve applied a heading 1 style to that particular piece of text i then have london underneath and i have a heading 2 style applied to that and what i now want to do is add in a couple of pictures of some of the main sites in london so i’m going to jump up to the insert tab i’m going to jump into pictures and it’s going to open up file explorer so all you need to do now is navigate to whichever folder you have those pictures stored in and there we go i can see a selection of pictures so i’m going to add in tower bridge i’m going to hold down control and also select the london eye and click on insert and it’s going to pull both of those pictures through now one thing to note when you insert multiple images in this way is that they will become part of the same container the same placeholder so maybe if i want this bottom image to be next to this image of the london eye if i click on it when i drag i’m essentially dragging it out of that particular placeholder now you might think to yourself well why is that a problem well if i then wanted to add some more text in if i hit enter a couple of times it’s going to move down one image but this image is going to stay where it is so just be aware of that if you do drag an image out of its original placeholder you may have to reorganize its placement on your particular page alternatively i’m going to control zed a couple of times just to put this back how it was so now what i might want to do here is click next to london press enter a couple of times and then just add some bullet points which has london eye tower bridge and of course again if you don’t like the font you can go in and change the font for any of the text in your notebook now what i’m going to do is i’m going to click somewhere over in this blank space on the page and i’m going to create another placeholder and this one is going to be called paris i’m going to double click and give that a heading 2 format so it matches london i’m going to drag the placeholder out and just reposition that very slightly now when it comes to lining things up because really i want this paris heading in line with this london heading you are a bit limited with options but one thing i will generally do is jump across to the view tab and turn on raw lines so this just gives me some paper lines running across the page and i just find it a little bit easier to line things up when i have these turned on so now i’m going to add some bullet points we’re going to have eiffel tower and sacra ke let’s apply some formatting so it matches the rest of the document and now i’m going to add in my images so up to insert across to pictures it’s going to default to the last folder that i was in i can pick up the image of the eiffel tower hold down control select sac recur click on insert and it’s going to add those images in for me and of course these images can be resized if you need to do that but there we go fairly straightforward to insert pictures that you have stored off locally so now let’s take a look at how we can add in online pictures now this is pretty much exactly the same as jumping into google or a different web browser googling an image saving it off and inserting it but it’s just a little bit quicker as we’re missing out some of those steps what i can do is click on online pictures and it’s going to jump me across to a image gallery browser which is powered by microsoft bing and what i can do is i can utilize images in any of these galleries alternatively if i know what i’m looking for i can just type my search term into that online picture search bar so i’m looking for an image of big ben i’m going to hit enter and there you go so let’s select this one and click on insert and it’s inserted that very nicely into the bottom of this document i’m going to do the same thing but i’m going to add an image for paris this time so let’s jump up to online pictures once more and i’m going to type in notre dame and hit enter this image looks pretty good to me i’m going to select it but one thing i want to point out here is when you are adding online pictures into your documents it’s really important that you check this little setting just here you want to make sure that you’re searching and using only images that have a creative commons license so it basically means you can use that image for not-for-profit reasons so if this is just a one note team notebook that’s going to be shared between me and maybe three of my colleagues then that’s absolutely fine any of these images i can use because i’m filtering for creative commons license now even when you have this filter on if the notebook that you’re adding it into is going to be used for any kind of commercial purpose so if you are going to demonstrate this to a wide audience or if you’re going to create a youtube video something that you’re going to get money from then you need to delve a bit further as to whether you can use this image a lot of people make the mistake when it comes to copyright by thinking that if they have creative commons selected they can use any image that comes up in any type of document and that’s simply not the case and a lot of people have been caught out by this if you’re using it for a non-commercial purpose then yes normally it’s fine but otherwise you might want to review and you’ll see here right at the bottom it says you are responsible for respecting others rights including copyright and then you have a link to learn more here so if you’re not entirely sure what creative commons licenses are then it’s definitely worth having a read up about that before you start to use these images in any commercial projects now just while we’re in here we do also have a filter button which allows us to search for specific types of images so i can search by size i can search by type so if i want to photograph a clip art or if i want something that has a transparent background and this is an option i use fairly frequently sometimes maybe i’m looking for an icon or maybe a logo but i don’t want to have any background even if it’s just a white background i just want images that have transparent backgrounds and you can also do things like search for images by their layout so square white tall and also color or black and white photographs only so don’t forget about those filters that you have within this little area now for this particular image i don’t need to do any of that i’m going to click on insert and it’s going to pull that through and once again i can just go ahead and resize that as necessary i’m going to jump up to the top of this document and just add in another bullet point so we’re going to say big ben and then for paris we’re going to say notre dame like so so pretty simple and straightforward to add pictures into your notebooks if you’ve used microsoft applications for a while this will be like second nature to you we’re going to move on to the next module now where we’re going to talk a little bit about inserting video into your notebooks so i’m looking forward to that i hope to see you over there hello everyone and welcome back to the course in the last lesson i showed you how you can insert pictures both online and locally saved pictures into pages in your onenote notebook but did you know that onenote also has the ability to embed videos right into your pages and adding videos really makes your notebooks come alive and they’re particularly good if you’re creating an interactive notebook to share with others it’s worth noting at this stage that inserting video is a little bit different to inserting pictures when it comes to video you cannot insert a video that you have saved off locally so if you’ve got your own video stored off to file explorer there isn’t an option to browse your local drives to upload that video and add it into your notebook what you can do however is pull in videos from other video sites so online video essentially and if you take a look at that insert ribbon in the media group in the middle you’ll see exactly what i mean we just have one option here which is online video so if you have a video that you’ve uploaded to youtube then you can essentially embed that link into the page now if you’re wondering which sites you can embed video from i would advise you to jump onto the microsoft help page if you search for embedding videos in onenote you’ll get to this page and that goes through and shows you all of the currently supported sites and services and you’ll find in there most of the ones that you’re going to want to use are listed there so we have things like dailymotion vimeo youtube ted talks all of those kinds of things and microsoft do advise that you check back here periodically as they’re consistently adding more and more video sites to this particular list so let’s jump back to onenote and let’s take a look at how we can add an online video now for this i’m going to go across to my courses section group and i’ve got the excel section selected and what i want to do here is add in a tutorial video related to excel pivot table so this might be something that we want to send out to different staff members in offices to back up the in-person training that they’re gonna get when we roll out microsoft 365. now if i was to click on online video what you’ll see is that immediately it asks for the video address and you’ll see underneath it says view supported video which is going to jump you to that help page that i was just showing you so really what you need to do here is jump onto youtube or dailymotion or vimeo grab the url and then come back to this option so that’s what we’re going to do i’ve just jumped into youtube i have the pivot tables in excel open i’m going to copy url control c jump back to onenote and then go to online video control v to paste it in if i click on ok it’s then going to embed that video into my page and what i get here is a clickable link so if i click this it’s going to take me to youtube where i can view the video but i can also view the video from within my onenote page so if i click on play that video is going to start and i can move through the video as i would on youtube or any other video application so super straightforward you just need to make sure you grab the url first and then just paste it in to embed that video that’s it for now i will see you in the next module hello everyone and welcome back to the course we’re down in section three where we’ve been taking a look at adding different types of content into our onenote notebooks and in the previous few modules i’ve shown you how you can add in screen clippings pictures online pictures and also online video now in this and the next couple of modules we’re going to concentrate on adding files into our notebooks and adding files is just another way of gathering together information that’s going to be useful to anybody who has access to this notebook it’s also a great way of saving time so for example instead of retyping information or maybe relying on links to documents that might become unavailable if you go offline you can bring content that you need directly into onenote either as an attachment or as a printout that you can annotate and you’ll find these options on the insert tab in the files group and it’s these three that we’re going to concentrate on over the next couple of modules so let’s start out by taking a look at inserting file printouts now when you insert a printout it basically allows you to select a file that you have stored in onedrive or locally and that could be any kind of file it might be a word document an excel spreadsheet powerpoint pdf anything like that and it’s going to print the contents of that file into wherever you’re clicked so in my case i’m in the schedule section and i’m clicked on the course plan page so let’s click on file print out and you can see it’s going to jump me across to file explorer and i have a word document here called course descriptions that i want to add into this notebook now it’s worth noting that i just have some junk text inside this word document to demonstrate this but hopefully you’ll still get the idea so i’m going to click on insert and you’ll see exactly what that does so it prints the contents into the actual page now it’s worth noting that this is a copy so when i click on this page i get my resize handles at the side but it doesn’t let me directly edit the text from within onenote however if i did want to update this text you’ll see just above i basically have a link back to the original word document so what i can do if i want to update is i can double click to open in word i can go in and make my changes save the document and i’m going to close down word now what you’ll see when i go back to onenote is that it doesn’t automatically update you can’t see that text that i’ve just added onto the beginning of the first paragraph what i do have just above it says the printout below may be out of date right click here to refresh so all i need to do is right click and then in the contextual menu i have a refresh print out option so if i click this it basically reloads that print out and now you can see that my changes have updated so that’s one important point to note when you insert it you’re essentially getting a copy that you can’t edit within the notebook but you can edit the original and then just refresh the printout to update it now if you come across a situation where you have inserted a printout and then maybe you want to copy and paste this first paragraph into another page well you can do that as well if you click on the printout and right click your mouse you’ll see you have an option here for copy text from this page of the printout so i’m going to click to copy and that’s going to copy everything it doesn’t allow me to select a specific paragraph so i’m going to just quickly add a new page and if i right click and paste it’s going to paste all of that text in and i can then jump into the text and this is in fact editable so i can make some changes i can select different paragraphs copy and paste elsewhere so on and so forth so that’s a really useful little option as it essentially makes the text editable and allows you to do other things with it so let’s add another page and move on to the next option which is file attachment so this is more like adding a file attachment like you would in an outlook email or something along those lines if i click file attachment again it’s going to jump me into file explorer and i can select a document to attach so this time i’m going to select the course descriptions pdf click on insert and i get a choice of attaching the file or inserting the printout now if i was to select insert printout that is basically exactly the same as selecting file print out from here so we’ve pretty much just run through how that works so let’s go for attach file instead and as you would expect this looks a lot like an email attachment it just gives you a link to your document and of course you can double click to open that up and because it’s a pdf it has opened in a web browser for me once you’re in here of course you then have lots of different annotation tools if you do want to make changes to it but essentially what you have here is a link to the original document so any changes made in that document will automatically update the next time you open you’re going to see the latest version so that’s all very straightforward now before we carry on so we don’t get too crazy i’m going to rename some of these pages so i’m going to title this one course details and the other page that we created i’m actually just going to delete that one out now the final option we have in here is to insert a spreadsheet and if you click the drop down you have two options you can insert an existing excel spreadsheet or you can create a new excel spreadsheet so let’s go for existing excel spreadsheet first of all again it’s going to jump me into file explorer i can then select an excel spreadsheet click on insert and this time i get three different ways i can insert this file so i can attach the file which means it’s going to show very similar to this pdf it’s going to be a link back to that original document i can insert the spreadsheet or i can choose to just insert a specific chart or table so let’s go for the insert spreadsheet option and there we go so i’m going to move this over like so now this spreadsheet had four different workbooks so i had a chart which you can see there i then had some data and i then had a list of employees and you can see here it’s brought everything in that workbook into my onenote notebook and once again if you don’t want to make any changes if i double click on where it says course plan europe it’s going to open up in excel and let’s just make a simple change let’s make a formatting change here i’m just going to change the color of these bars to a dark red color i’m going to save and close down and this time you’ll see that it has automatically updated with those changes that i’ve made so it works slightly different to inserting a printout even though it looks fairly similar it does link directly back so any changes you make to the original document will automatically update in your onenote notebook now i’m going to scroll all the way down to the bottom here and let’s take a look at this final option which is new excel spreadsheet so what this essentially allows you to do is create a new excel spreadsheet directly from within onenote and you can see here i have an edit button and if i click on edit it basically opens up a temporary excel spreadsheet for me and i can start to add data i’m just going to add a couple of columns click on save close it down and you can see that that data then updates so a great way of creating a spreadsheet kind of on the fly if it doesn’t already exist somewhere on your system so those are all the different ways that you can add files and documents into your onenote notebooks in the next module we’re going to move on to talking about recording and i’m going to show you how you can add audio and video recordings into your notebooks so i’m going to head over there now i look forward to you joining me hello everyone and welcome back to the course we’re still down in section three where we’ve been taking a look at adding different types of content into our onenote pages and what we’re going to take a look at now is how we can record and add to our notebooks audio and video files now it might be at some stage when you’re working in your notebooks that you want to maybe take a quick audio note or record a video and the cool thing about this little feature in onenote is that if you do record a piece of audio or a piece of video and insert it into your page if you type any notes as you’re recording your audio or video the notes will essentially bookmark within the audio or video file so you can easily find the place in the recording where you typed your note so let me show you an example of both so we’re working up on the insert tab and you can see that i’ve just added a new page to the travel section called recording audio and video i’m going to click my mouse somewhere on this page and then in the recording group we’re going to choose record audio now what this does is that as soon as you click on that button it’s automatically recording everything that you say and you can see the audio files sitting there nicely in the onenote notebook underneath we have the time that the audio recording was started and if you take a look up to the ribbons at the top you can see i now have a contextual ribbon that’s called recording and this contains all of the options i might need in order to manage this audio recording so currently because it is recording i have a pause and a stop button and you can see as i hover over those they both have keyboard shortcuts now it might be that you are taking a recording of a meeting or maybe a lecture or something like that and as you’re recording you might also be making notes so let me show you how this works so if i take some notes just here so i’m going to type taking notes for audio recording [Music] and if i was to type something else so i’m just going to type in test test test test i could carry on going but now when i stop this recording so i’m going to press stop on that contextual ribbon i now have a couple of different ways that i can play this audio recording back if i just want to play the whole thing you can see if i hover over this file i get a little play button next to it and i can click play yo now what this does is that as soon as you click on that button it’s automatically record but alternatively what i could do is if i hover my mouse over my notes underneath you’ll see that each line of notes also has a little play button next to it so this is essentially bookmarked in the recording where i was when i was taking this note so what i can do is just click on play so if i take some notes just here and i could do the same for the line underneath recording so it essentially keeps track of what was being said at the point that the note was written now this also works for video as well so if we go back to the insert tab and click on record video this is going to pop open a window hi everybody nice to see you and it’s going to allow you to take a recording in exactly the same way so if i’m again working through this and typing in some notes so i’m going to say typing notes for video recording again that’s bookmarking where i am in my recording when i typed that note so now if i press stop on the contextual ribbon i can choose to either play back the entire recording or just the part where i took the note if i’m again working through this and typing in some notes so i’m going to say typing and it’s as simple as that now you’ll also notice that when these recordings start to play some of these other buttons in the playback group become active so you can do things like rewind for 10 minutes rewind for 10 seconds and also fast forward and then right on the end here we have audio and video settings so this is where you can customize how onenote creates and plays audio and video recordings and this is essentially going to jump you into your onenote options where you can set up things like your default audio recording device and also your video recording settings so this is particularly helpful i find if i’m ever in a training course or there is something that someone is saying that i want to make sure i get correct you can start a quick recording record it all and then you can type your own notes that is it for this module i will see you in the next one hello everyone and welcome back to the course we’re still in section three and in this section we’ve been looking at adding content and it’s now time to look at adding links into our notebooks this is a very simple process again if you’re used to using microsoft applications then you’re not going to find this difficult at all because it’s pretty similar to every other application so occasionally you might need to add links to external websites or even links to other documents into your notebooks so for example i’m currently clicked on the travel tab and i’ve created a page and i’ve called it flights so what i might want to have in here are some links to websites where you can book flights and to do this we’re staying on the insert tab and you’ll see right in the middle we have a group called links and we only have one option in there you can see as i hover over it says create a link to web pages files or other places in your notes and the keyboard shortcut to bring that up quickly is control k so let’s click and see what we get now the first two links that i’m going to add are links to external websites now there’s a couple of different ways that you can approach this the first box you have to fill out here is text to display so i’m going to put in here expedia i now need to add in the link to that particular website and you can see just to the right i can choose to browse the web from here or if i already have the website open i can just jump across and copy and paste the link so i’m just going to go to microsoft edge where i have a few different websites open and the first one here is in fact expedia so all i’m going to do is click in the url bar to highlight that web address control c to copy i’m going to jump back to onenote and ctrl v to paste it into the address field i can then simply click ok and it adds in that link let’s do another one but in a slightly different way i’m going to hit enter i’m going to go back up to link this time i’m going to display a link to sky scanner but i’m going to use the browse the web option so let’s click and this time it opens up the default page in my default web browser which for this is microsoft edge i can then simply navigate to http://www.skyscanner.net i can then copy the link control c jump back to onenote and then paste that address in so it’s pretty much exactly the same just a slightly different way of getting to your web browser and now i’ve managed to add in another link now i’m just going to give these a little bit of a title [Music] recommended sites for booking flights and then i have my two links to my web pages and of course if i hover over i can see the url if i click it’s going to jump me to that particular webpage so all very straightforward and simple let’s look at some other options that we have underneath link now what we can also do is we can choose a file to link to so if i click browse for file just here i can navigate to where i have my file stored and it’s this one just here flights.x click on ok i’m going to have the text to display as suggested flights and click on ok so now essentially i’ve created a link to a document and you’ll see when i click it’s going to open that document up in word now the final option that i have in here is i can link to other sections within my notebook so you can see at the bottom here i can expand the project artemis notebook it’s going to show me all my different sections and i can choose any one of these sections to link through to so i’m going to link to the overview section the text to display is guide for flight dates click on ok and that’s exactly what i get so if i now click it’s going to jump me to that particular section so those are the different kinds of links that you can add into your notebooks and of course if you right click on any of these you get a contextual menu which is going to allow you to jump in and edit that link if you need to make any changes you can also remove the link from here select it or copy it and that is pretty much it it is as simple as that in the next module we’re going to explore how to add equations and symbols into our onenote notebooks so please join me for that hello everyone and welcome back to the course we’re heading towards the end of section three and i just want to start to round out this section by running through a few other things that we haven’t looked at yet which you can insert into your onenote notebooks and what i’m going to go through in this module is inserting equations and symbols now i will say when it comes to equations this isn’t particularly relevant for the notebook that i’m constructing but you may find there are times where you need to insert some kind of mathematical equation into your notebooks and fortunately onenote provides an equation editor to assist you with this so let’s take a look at some of the things that you can do now again i’m still working on the insert tab and if we go all the way across to the last group that’s called symbols you can see we have in there an equation button and this is a two-part button so i can click on the top half or i can click on the lower half so let’s click the lower half first of all and what you’re finding here is a whole host of predefined equations that you can just click and insert into your notebook so for example if we take the top one just here which works out the area of a circle i can click and it’s going to insert that equation into its own little placeholder in my notebook and of course you can format this however you like using your tools on the home ribbon now when i insert this equation another thing that you’ll notice is that i then get the equation contextual ribbon and remember contextual ribbons are ribbons that only appear as and when they’re needed so from here you have lots of different options for manipulating this particular equation you have a large symbols group in the middle so if you need to change any of the symbols or add symbols then you can definitely do that and then in the structures group there’s all these other different types of fractions that you can add in to your equation now remember all of these buttons are for adding to the current equation that you have you’ll see if i was to click away that equations ribbon disappears so just be aware of that you must be clicked in your equation in order to see this ribbon but for example if i was to press space just here go up to structures and click the fractions drop down i could choose this first option just here which is a stacked fraction if i click it it’s going to add that to my equation and of course then i can add numbers to this and customize it to my needs now if i click away from this equation to get rid of that equations ribbon what i could also do is jump back to my insert tab and i could create my own equation from scratch there’s a couple of different ways i can do this if i click the lower half of the equation drop down you’ll see right at the bottom i have an insert new equation button and the keyboard shortcut for that is alt plus equals alternatively in a much quicker way of doing this is to click the top half of the button which then just gives me essentially a blank placeholder and i can construct my own equation from here and you’ll see once again i get my equation ribbon back again and i can go in and choose whatever equation it is that i want to add in and everything within these equations can be modified simply by clicking in the placeholder and replacing the characters or the operators now if you are somebody who is using a touch screen device then you also have a few extra options so once again let’s jump up to insert and i’m going to insert a blank equation so if you have some kind of stylus that you use with your touchscreen device what you can do is handwrite out your equation and then one note will do its best to convert it to text for you so in this first group here the tools group we have a button called ink equation and it says insert mathematical equations using your handwriting so let’s jump into here and we get our insert ink equation box and what i can do is i can now write my equation using my stylus and get one note to convert it for me now what i’m going to do is i’m going to drag this box out to make it a bit bigger and i’m going to use my stylus because i am using a touchscreen device to write out my equation and let’s just use einstein’s most famous equation e equals m c squared so i’m going to do my best to write this out but there we go and you can see just above it’s giving me a preview of what it thinks i’ve written and in this case that looks to be correct now if i need to make a correction when i’m writing this out you can see at the bottom we have some options for manipulating our handwriting so i could choose select and correct and then i can draw around whatever it is that i want to correct i wonder it’s going to provide me a few different options that it thinks i might want to do from this little menu now in this case i don’t want to correct it i’m just going to click on close and i can also erase any of my handwriting as well so if i click on erase once again i can just drag it over whatever it is i want to get rid of and of course if i want to clear the whole lot and just start again then i have a clear button down here now i’m going to go back into right mode and just add that to back in like so and i’m fairly happy with that so i’m going to insert it into my page and there we go we have our little equation so that’s particularly good if you have a very bespoke long equation that you want to add in instead of going through all of these different structures and symbols you can simply open up the ink equation editor write it down and then onenote will do its best to convert it and you can make any corrections that you need to make so equations probably not something you’ll use all that frequently but just know that it’s there and you can use it if you need to finally let’s jump back up to insert and quickly look at symbols now again this is fairly straightforward this will just allow you to insert any symbols into your onenote pages and you can see there i have a selection of a few that i’ve used most recently if i want to see the full list of symbols i can just say more symbols and it’s going to bring up that full list and i’m going to insert one of these symbols now let’s just move that window out the way because i’m going to go to the offices section i’m going to select the london office and you can see here i have the office address so what i’m going to do is just click at the start of office address and just add in a little symbol i’m going to add this little envelope one so i’m going to click insert close i might want to put a little bit of space in there so it just adds a little bit more interest into my onenote page so don’t forget you have a whole host of different symbols that you can use in your pages as well again this is a feature that’s available across all of the other microsoft applications so that’s it for this module very straightforward equations and symbols use them when you need to that’s it for this module i will see you in the next one hi guys welcome back to the course we’re down into the last module of section three and in this section we’ve been seeing how we can add all different types of content into our onenote notebooks so i’m just going to finish up this section by running through the options that you have when it comes to copying and pasting content from other documents into your notebook the first thing i’m going to do here is create a new page so i’m going to jump into my courses group i’m going to click the plus to create a new section and we’re going to rename this one onenote and hit enter and this page is going to be called training script and what i want to do is i want to take the training script what i’m going to say in this particular course from a word document and paste it into this page in onenote and this is fairly straightforward if you’re used to copying and pasting things across different microsoft applications you’re probably not going to have too many worries but let’s run through it because there are a couple of things when it comes to pasting that you need to be aware of so i’m going to jump across to a word document and all you need to do is make your selection so select the text that you want to copy and paste so i’m going to say i want these first few paragraphs and then of course you need to copy it and you can use whatever method you want to use in order to copy this text so that might be control c if you like your keyboard shortcuts alternatively up on the home ribbon you have a copy button or you could right click your mouse and select copy from the little contextual menu so let’s click copy and jump back to onenote so now what i’m going to do is i’m going to paste this text in now you’ll find your paste options on the home tab in this first clipboard group now again this is a dual button so it’s split into a top half and a lower half now if you click the top half of this button it’s exactly the same as doing a control v to paste and what onenote will do is it will use your default paste option in order to paste that text in if you’re wondering what your default paste option is if you click the lower half of the paste button whatever icon you have showing first is going to be your default paste option so for me that is to keep the source formatting so what that means is if i just do control v it’s basically going to retain all formatting from the source document so if i have my font formatted in times new roman in the source document if i was to choose keep source formatting when i paste it’s still going to be in times new roman in onenote now of course i have a few other options in here i could choose to merge formatting so that means whatever my default fonts are in onenote when i paste text in from another document it’s going to take on the formatting that’s set in onenote the third option i have is to keep text only so that’s going to bring across unformatted text and you can do whatever you like with it or i could choose to insert the text as a picture now i’m just going to do that just to show you the difference with this option let’s select picture and what you’ll see is that within the placeholder if i click i now get these handles around the outside so onenote is treating this as a picture which means i can’t just jump into this text and edit it so just bear that in mind if you decide to use that option now i’m going to control z just to undo that and what i’m going to do is i’m going to select keep source formatting paste that in and there we go and you can see with this option i can jump in and i can make any changes i need to this text and what you’ll also see at the bottom is that i have a link back to the original document if i need to refer to it at any stage so that was copying and pasting text from a word document into onenote let’s run through one more example of copying and pasting something from excel into onenote so i’m gonna go back a level and i’m just going to jump to where it says schedule and click somewhere down here now if i go to excel you can see i have an excel worksheet here that has the course plan table on it so what i could do is select this entire table i can click on copy jump back across to onenote and then once again i have my different paste options so this time i’m going to select merge formatting to pull that through and it’s going to take on the default formatting that i have in this onenote notebook if i control z just to undo that and do it once more but this time i’m going to say keep source formatting you can see i get something slightly different because it’s bringing across the formatting from the original source document so the main takeaway from this lesson is just be aware of those different paste options that you have and how they can affect the look and feel of the content that you’re pasting in that’s it for this module that is it for this section in the next section section four we’re going to move into taking a deeper look at formatting our notes so i’m excited grab yourselves a coffee and i will see you over there hello everyone and welcome back to the course it’s time for us to take a look at some of the options that we’ve run through in this section in onenote for windows 10. so we are pretty much picking up from where we left off in the last windows 10 tutorial and if you remember we created a project called project sierra we created some sections and some pages and then i showed you how you can make sub pages and we also took a look at the main options that we have in the onenote for windows 10 interface so let’s move on a little bit now and start taking a look at how we can insert items into our pages now this is fairly straightforward in onenote for windows 10. all of your insert options are found on the insert tab and from here you can insert various different items like tables files printouts pictures and online video as well as things like links and audio meeting details symbols so on and so forth so fairly similar in that way to the desktop version now when it comes to typing notes this works in exactly the same way you just click somewhere in your page [Music] and type your note and you’ll see that the note appears in a very similar placeholder that you can pick up and move around you can also resize it by dragging it out to give yourself a little bit more room and you can pretty much place this wherever you want on your page now when it comes to formatting text that you have within placeholders if you jump back to the home tab this is where you’re going to find all of your formatting options that you have available so i can make this bold i can make it italic i can highlight it i can even do things like copy the formatting using format painter or add things like bullet points and numbered items now i’m gonna do undo a couple of times just to take that back to the plain text because what i want to focus on in this particular lesson is things that you can insert into your notebook so let’s jump back to the insert tab and let’s start out by taking a look at how we can insert a table so i’m going to click the table button and again this is probably fairly similar to what you’re used to i’m going to select how big i want my table and very quickly i’ve managed to insert a nice table into here and i can now start to add in my required data now i’m going to select that placeholder and just delete that out and just show you a couple of other options that you have on this ribbon because most of them are pretty much the same as the desktop version so let’s click on file and i’ll just show an example of inserting a file into your notebook so i’m going to select this word document just here and click on open and i can choose to upload it to one drive and insert a link to it i can insert it as an attachment or as a printout so i’m going to say insert attachment and just like that we have that document sitting there ready to open we can insert pictures in pretty much the same way we can choose to insert a picture that we have saved off we can choose to select one from a camera or from an online source so if i was to select from online it’s going to open up a pane where i can then search for a particular picture so let’s just say london i can then choose the picture that i want and it’s going to insert that very quickly into my notebook now once again i’m going to click on undo to get rid of that now when it comes to something like online video again this is where you’re going to need to know the exact url of the video that you want to insert so you might have to jump onto youtube or vimeo grab the url paste it in here in order to put your video into your notebook now pretty much everything else in this section is exactly the same in the desktop version as in this one when it comes to copying and pasting you can utilize exactly the same keyboard shortcuts so for example if i press ctrl c to copy click down here and ctrl v to paste that’s going to work nicely now if you’re looking for your cut copy and paste options on that home tab you’re going to need to click on the clipboard and then you’ll see a drop down menu with those three available in there so when it comes to inserting items into this particular version of onenote fairly straightforward insert tab there you have your options and for the most part it works pretty much the same as the desktop version that’s it for this module i will see you in the next one hi everyone welcome back to the course this is still deb and we are down into section four where we’re going to be taking a deeper look at formatting notes now formatting is reasonably simple but it’s a very important process because it makes your text more readable it allows you to emphasize certain points and also gives a bit more structure to content that you have on your page and i’ve been utilizing font formatting throughout this course so far but in this particular module i just want to delve into all of the options that you have so that you’re clear and can format your notes effectively so i’m currently clicked on the onenote section in the training script and you can see here currently i have a few paragraphs of completely unformatted text now i can see in here i have some spelling errors that i might want to correct and i’ll do that later but for now i want to give this a bit more structure make it a little bit more interesting by formatting my paragraphs now in onenote you can choose to format everything that you have on your page or you can select specific paragraphs to format so let me show you examples of both now if i click on my text you can see that i have this placeholder around the outside now if i select that placeholder i’m effectively selecting everything contained within the placeholder so any formatting that i apply at this point is going to apply to everything within the placeholder what you’ll also see is that as soon as i clicked on that placeholder i get my mini toolbar just above and the mini toolbar holds lots of different formatting options to make it a bit more convenient when it comes to formatting now currently i’m clicked on the home ribbon where i have all of my formatting options but it might be that i’m clicked on a different ribbon and i want to format some text so instead of having to jump back to home to get to those formatting options the mini toolbar gives me quick access to them wherever i am so the first thing i’m going to do here is i’m going to change my font style so currently i have this set to calibri and if i click the drop down this is going to give me a list of all of the inbuilt fonts within onenote you’ll see at the top i have my most recently used fonts and then i have a list of all of the fonts within one note in alphabetical order which makes them a little bit easier to find now if you know the particular font that you want to use you can scroll through the list and look for it or alternatively you can just start typing the name of that font and it will jump you to the correct place in that list so for me i’m going to use lato light and you can see as i type it it’s found that in the list it’s the last one just here if i click it it’s going to apply that font to everything i have within that placeholder now currently i have a little title here called what to expect from this course and it doesn’t really stand out from the rest of the text so what i could do is just select that line of text as opposed to the entire placeholder jump up to my font drop down and this one i’m going to select lato again but this time i’m going to choose lato black so what i’m doing here and this is quite important is i’m sticking within the same font family i’ve used lato light for my paragraphs and i’m using latte black for my heading and this ensures that my fonts aren’t going to look too different to each other as they’re within the same family it just gives a more consistent overall look and feel there’s something else i might want to do here is i might want to select that heading again and increase the font size so once again from the drop down menu currently i’ve got 11 point font selected but i could choose something that’s a little bit bigger just to make that heading stand out a little bit more now underneath those two options we have some additional ways of styling up our text we can make text bold and you can see the keyboard shortcut there ctrl b italic we can underline we can add a strikethrough to cross something out and then we have a choice of subscript or superscript so for example if you typed the word h2o you could use superscript to make that look correct so let’s just apply some of these options i’m going to take the let’s just take this first sentence in the second paragraph i can make it bold i can make it italic i can underline it i could strike through and if i type in h2o what i could do is select the number two jump up to my superscript and subscript button and make it superscript so that looks a little bit more accurate now i don’t actually want all of this formatting applied so i’m going to delete out the word h2o and what i’m going to do is i’m going to highlight this whole sentence again and if we go up to our basic text group you can see here i have a clear or formatting button keyboard shortcut ctrl shift n and you can see it says it removes all formatting from the selection leaving only the normal unformatted text so when i click this it’s going to remove absolutely everything including the font style that i selected now in this case it’s a little bit quicker for me to use this button and then just go back in and reselect later light to apply that font but in some cases it might be quicker for you just to highlight the sentence and undo all of the formatting that you applied now a couple of other options in this second group that we have here we have a text highlighter and i showed you how to use this before it’s a really nice little option if you want to highlight or make something stand out in your bulk of text so let me take this sentence here where i’m introducing myself and if i go up to highlighter click the drop down i have a choice of different highlight colors so let’s highlight this in a bright green and there we go and once again if i wanted to remove that i can select the text and i can go back into here and choose no color or i could clear the formatting but remember it’s going to clear that font style as well and take it back to your default and then of course if we highlight this first paragraph i can change the font color and i have a selection of theme colors to choose from and then a selection of standard colors now if i’m not finding the color that i want in this palette i could click on more colors i can choose from a standard color selection or i can go to custom and get super granular about the color that i’m choosing so i can move around this color palette and let’s go for a purple i’m going to go for a lighter purple and you can see in the bottom corner it’s showing me what that color is going to look like click on ok and then it’s going to apply that to whatever paragraph i have selected now i’m going to ctrl z just to put that back to black now the final few options that we have in here are the increase and decrease indent so once again if i wanted these first two paragraphs to be slightly indented from the rest of the text i could select them and choose to increase my indent position and it’s going to indent those and if i want to do the opposite again i can select and i can choose to decrease my indent position to move that back again then finally underneath i have some alignment options so currently my text is all aligned to the left now for this i’m actually going to select the entire placeholder and i’m going to say align to center and you can see i get a completely different layout for my text i could also choose to align to the right and that’s sometimes useful if you want to move your text box over to here it gives it a different look and feel now again i’m going to ctrl z just to pull that back to align left and then right at the bottom we have some paragraph spacing options so currently you can see the spacing in between my paragraphs is reasonably small so it might be that i want to increase that to make it a bit more obvious and prominent so if i go down to paragraph spacing options i can choose how much space i want to set before the paragraph and how much space after and i’m going to say i want 20 point spacing afterwards click on ok and you can see i get a much wider gap after each paragraph and the final button that we have in this little basic text formatting group is the delete item button so this is just another way of being able to very quickly select a paragraph so if i hover over the second paragraph you’ll see i get a little arrow at the side i can click it to select the paragraph i can click delete and it’s pretty much the same as pressing the delete key on your keyboard so that is it a very quick run through of all of those font formatting options that you have available in the next module i’m going to show you how you can utilize format painter so please join me for that hello everyone and welcome back to the course we’re down in section 4 where we’re taking a look at formatting and in the previous module i showed you the different options that you have when it comes to formatting paragraphs of text in your notebooks now in this particular module we’re going to follow on from the previous one i’m going to introduce you to the format painter now again this is something that i use towards the beginning of this course but i want to make sure that you understand exactly how to use it because there are a couple of things that aren’t immediately obvious so once again i am working in the training script page and i’ve added a bit more text into this page now if you take a look at the text that i’ve actually added i have some times 10 to 12 and also 2 to four a bit further down and i want to make those stand out from the rest of the text on the page so once again what i can do is i can hover my mouse over the little arrow that appears in the margin and click to select that piece of text now if i want to select another piece of text i can hold down my control key click to select that line as well and i’m going to make both of these bold like so and then underneath i have a list of items that i’m going to cover and then underneath each of these headings i have essentially a list of agenda items so again what i might want to do here is apply some formatting to make them stand out and give this notebook a little bit of structure so the most obvious thing i might want to do with some kind of list would be to either add bullets or numbering and if we jump back up to our basic text options you can see i have a whole host of different symbols that i can use as bullets so i’m going to pick this little tiny black square click to add that in now an alternative option to adding in just symbols as bullets is that you can number items as well so if i go up to the button next to bullets we have a numbering option and this is going to pull up the numbering library and it shows me all the different styles of numbering that i could choose so again it really depends on what your personal preference is or what matches the overall theme of the notebook that you’re working in so for this one i’m actually going to choose these roman numerals click to add those in and when it comes to things like numbering you’ll notice that if i click on one of the numbered items it selects them all so if i wanted to change to a different style of numbering i can just jump back up to numbering and then choose whatever it is that i need to now the final thing i want to show you in this lesson is how to utilize the format painter so what i’m going to do is i’m going to press enter and you’ll see that automatically it’s going to give me my next numbered item now i don’t want to have a numbered item here i want to create a new heading so all i need to do is i can just click on numbering but you’ll see that it’s going to leave my cursor indented so if i want to pull it back so it’s flush with that left-hand margin this is where i would use my decrease indent position and when i click that it pulls it back to where i need it to be so i’m going to add another heading in here we’re going to say 4 to six and i’m going to add in a few more items now a quick way of me formatting this new list the same as the list that i have above is to utilize the format painter and what the format painter does it allows you to select a piece of text that already contains formatting and then essentially transfer it to another piece of text so in this example i want this heading 4 to 6 to look exactly the same as the one just above two to four now in practice this just contains bold formatting so it’s not too much of a hassle for me to just apply bold but if i had multiple pieces of formatting applied so if i select it and maybe if i change the color maybe i’ve gone in and i’ve made it bigger maybe i’ve made it italic i’ve now applied a number of different steps and so to recreate those manually for this particular title is going to be a little bit time consuming a much quicker way of doing it would be just to select the text that contains the formatting you want to copy and in the clipboard group click on the format painter and you can see the keyboard shortcut there is ctrl shift c now i’m going to click the format painter once and you’ll see that my cursor changes to a paintbrush and now all i need to do is paint over and let go and it’s going to copy that formatting across now one thing you’ll also notice is that as soon as i’ve done that my cursor returns to just that standard cursor so what do i need to do if i want to carry on painting this format so we’re going to do the same again but this time i’m going to copy the formatting to multiple items so it’s the same process i’m going to select the text but this time i’m going to double click on the format painter i can then paint over this heading scroll up and paint over this heading and you can see that my cursor is still showing in paint mode so if you click on format painter once you only get to paint once if you have a lot of painting or copying of formatting that you want to do you need to double click on that format painter once you’re done with your formatting you can just click on format painter to turn it off alternatively you can press the escape key on your keyboard and that will take you back to your regular cursor so format painter is a great way of working a little bit more efficiently saving time and also ensuring that your formatting is consistent throughout your notebook that’s it for this module i will see you in the next one hello everyone and welcome back to the course in this section we’re taking a look at everything to do with formatting notes to give our notebook structure and make it easier for the reader to decipher exactly what they’re looking at and in the previous module i showed you how you can utilize bullets and numbering and also use that format painter to copy formatting to other pieces of content i’m just going to start out by finishing that up so if you remember right at the end of the last lesson i added in another list of items and currently these don’t have any bullets or numbering applied to them like the previous two sections and i want everything in here to be consistent i want everything to have bullets supplied as opposed to numbering so once again i’m going to select the text that contains the formatting i want to reuse and i’m going to double click on my format painter and i’m going to paint over the list below and then i’m going to paint over the final list and then i’m going to click on format painter to come back to my regular cursor so now everything’s starting to look a little bit more uniform and this is a really important point when you’re working in any application not just one note making everything look consistent is really important when it comes to the readability of the document that you’re creating and something that can help you with that is styles and you’ll see on the home ribbon in the middle we have a styles drop down and again this is something we took a look at very briefly in one of the earlier modules but let’s just delve into it a little bit deeper so you understand exactly why these can be useful now styles are essentially pre-formatted pieces of text which are available as standard in onenote and you can see from this drop down you get a little preview as to what each of these will look like when you apply them to any piece of content in your notebook and the idea of these is to give your document consistency and also structure and it also makes it a lot easier for you to very quickly apply formatting without having to manually apply it from your basic text formatting options so let’s take a look at how we might use these now at the top here i have the heading what to expect from this course and i just applied manual formatting to this i changed the font style i increased the font size to 14 and i also made it bold so that’s essentially three clicks to get the result that i want what i could have done instead was select this heading go to styles and select heading 1 and that’s going to apply that heading 1 style and all of the formatting to that heading and if whenever i have a heading in my notebook i consistently use heading 1 that’s going to make my document look a lot more tied together and it also saves me a lot of time because it just requires one click now i’m going to go in and i’m going to add a subheading here called agenda i’m going to select it and i’m going to give this a heading 2. i’m then going to select 10 to 12 and i’m going to give this a heading 3. so you can see that each of these headings as i’m applying them are slightly different from the previous one but they still give a cohesive look so let’s apply heading three to this one as well and also heading three down here now of course i could carry on going and it really depends how many subheadings i have in my document but i can utilize all of these throughout to give a consistent feel you’ll also see that i have some other styles available in here which i could also use so if i have a page title i might decide to apply this particular style if i have a citation or maybe a quote and what you’ll see is if i just show you if i select this paragraph maybe this is a quote and i want to emphasize that i could use the quote style and when i click in it you can see the formatting that’s applied for this style so it’s calibri font it’s size 11 it’s italic and if i click the font color drop down you can see the font color that it’s using highlighted in the theme colors palette so i can see all of the individual properties that essentially make up that quote style now i’m going to control z because i don’t need that to be a quote now i’m going to leave you to have a little play around with these see which ones you like which ones you don’t but they are a super quick way of just applying some kind of structure to your document that’s it for this module i will see you in the next one hello everyone and welcome back to the course in this section we’ll be taking a look at some of the options that we have when it comes to formatting our text notes and i want to move on from that a little bit in this module and run through some options that you have when it comes to organizing information on your page and we’re going to start by taking a look at tables now once again we’re going to be working predominantly on the insert ribbon as that is where we will find add tables option in the second group just here now again if you’ve worked in other microsoft applications such as word or maybe excel you may be pretty familiar with the concept of tables now if you are used to using tables in those applications then you might find the option in onenote a little bit limited there’s definitely not as much that you can do with a table in one note compared to something like word but nevertheless it can still be super useful for organizing text making things easier to read and also lining up items on a page so in this module i’m going to show you how you can insert a table and we’re going to run through the formatting options that you do have so i’m clicked on the training script page and what i’m going to do here is i’m going to add in a table which is essentially going to replace these bulleted items so currently the way i have this laid out these bulleted items take up quite a bit of room so i’ve decided that these would look a little bit better if i organize them in a table so i’m going to click after the word agenda and hit my enter key to put me onto a blank line i’m going to jump up to table and at this point i have a couple of different options i can select how many columns and rows i want in my table simply by dragging over the grid alternatively i can click on insert table and manually type in the number of columns and the number of rows now for me i always find it a little bit easier just to drag over the grid so i’m going to create a table that is seven rows by three columns click to insert and what you’ll see is you get this rather small kind of cramped up table now of course this is a little bit small for me to be able to work with effectively so the first thing i want to do here is resize these columns and it’s a simple case of hovering your mouse over the column boundaries until you get that double-sided arrow and just dragging out to the size that you want and of course you can adjust these later if you don’t have it quite right at the outset so let’s make this table a little bit bigger like so now one thing that you’ll notice again is that when i’m clicked inside this table if you cast your eyes up to the ribbons you can see that i now have a contextual ribbon called table and this ribbon contains all of the options that i have in relation to formatting and organizing this table so i have a select group first of all that will allow me to select the entire table i can select specific columns so wherever i’m clicked it’s going to highlight again i can select specific rows or i can just select a specific cell and all of these selection options are really dependent on where you’re clicked within your table now of course when it comes to selecting you can also utilize this little gray arrow in the margin if i want to select the first row i can click the grey arrow to select it and if i hover just above the table you’ll see that i get that black downward facing arrow which is going to allow me to select different columns i can of course drag my mouse so if i want to select a few different rows i can definitely do it that way or maybe if i want to select a few cells within one column i can do it that way as well so a few different options there when it comes to making selections the next group along is deleting so we can delete our entire table we can delete specific columns that we’ve selected or specific rows and then we have an insert group and this is going to allow us to insert additional rows either above or below where it clicked or additional columns to the left or to the right of where we’re clicked we then have a group that contains some formatting options so if i want to hide all the borders of a table i can do that and that will look a little bit more useful when we actually have some content within the table i can also choose shading so if i want to change the background fill of some of the rows or maybe a specific cell or column then i can definitely do that and then i have alignment options and this relates to the text contained within each cell i can choose to align it to the left to the center or to the right now we have a couple of other options on the end here which i’m going to cover at the end of this module let’s just focus on the ones that we’ve just run through so what i’m going to do here is i’m going to start to add some content in and in this first cell i want to have the text 10 to 12. so i’m going to select that text and i’m going to do control x which will cut alternatively you could have used the cut command on the home ribbon or you could right click and select cut from there i’m going to click in this first cell just here and i’m going to press ctrl v to paste that in and you’ll see that it’s pasted with all of its original formatting because i used ctrl v which essentially invokes my default paste option which is to keep the source formatting now underneath here i’m going to type in agenda item we’re going to have description and then i’m going to have time now one thing you might notice is that the font style has gone back to calibri because calibri is my overall default font it’s not picking up the latter light that i changed everything in this notebook to be so probably what i’m going to want to do here is select the entire table and to do that again i can jump up to the table ribbon and in the first group i can click select table and then i’m going to go to home and i’m going to change all of the font to lato light so that now ensures that everything that i’m going to type into this table is going to have the correct font style now another thing i’m going to do here with these column headings is i’m going to select the entire row and i’m going to make them bold and now i’m going to take these bulleted items and i’m going to cut and paste into the table so let’s select the first one ctrl x to cut ctrl v to paste and i’m going to do exactly the same for all of the others like so now you can see because i’ve just done a direct cut and paste it’s brought across those bullets as well now it might be that once you put them in the table you don’t have any need for the bullets so all you need to do to get rid of those is select all of the bulleted text jump up to the home ribbon and just deselect bullets to put those back now when i talk about tables in onenote being slightly less functional than in other applications i mean for things like this so for example this first row where we have the times if i was working in a table in say word what i would probably do here would be to merge all of these cells so we just have essentially one cell running across the top but you’ll notice if we go to the table ribbon we don’t have any merge options so you kind of have to keep it in this format what i’m going to do now is just go in and type in some text into the description fields so there we go i’ve added in a brief description for each of these agenda items and also the time that each item is going to start now it might be that i want to add another column that contains the room that this course is taking place in so what i might want to do here is first of all i’m going to drag this table board in as i don’t need as much space here i’m going to select this last column and i’m going to say insert right to insert another column now you’ll see as soon as i do that onenote is going to resize my table to accommodate the widest item in that column now normally this is fine but if you want to widen then you’re going to have to go in and manually widen these columns again so i’m going to say room and we’ll say room a room b c d and e now some other things i can do in here to liven up my table if i click in this heading row i can jump up to my select group and say select rows and just to make this stand out a bit i’m going to apply some shading so let’s apply some lilac shading to that heading row i’m also going to click where we have the times i’m going to say select cell and for this i’m going to apply bold formatting and then i’m going to select the time column so all of these items just here just by clicking and dragging my mouse and i’m going to make these italic now something else i also could do is hide these table borders so if i jump up to the format group i have a hide borders option which is just going to give me that so essentially it is still in a table and you can resize still by dragging but you’re just not seeing those table boundaries so sometimes that does tend to look a little bit neater and a bit more professional now just for demonstration purposes i’m going to bring those borders back and remember i can highlight two columns of content and maybe i want to center align those two now another option i have up here is the sort option so i can choose to sort the items in my table in ascending order so a to z or descending zed to a and this is really important here it’s got a tick next to header row my table’s a little bit different to most tables that you might create because my first row isn’t actually my heading row really where i have these column headings that essentially is my heading row so for me if i wanted to sort in ascending order and i have header row ticked one note is going to think that the first row is my header row and so when i sort it’s going to look a little bit strange so for me i can’t actually do that if i just want to sort the items so maybe i want to sort these agenda items into alphabetical order i would need to select them go up to sort and say sort selected rows i’m going to sort by column 1 in ascending order click on ok and now you can see that that has worked so just be aware of that header row option now essentially what i want here is this table for each of these different parts of the training course now what i find is the easiest way is just to copy this particular table i want everything to look pretty much the same so i’m going to click in my table up to my table tools select table and then going to go to the home ribbon and say copy or ctrl c if you want and i’m going to place my cursor where i want the new table to be and i can do control v to paste that in so once i’ve done that i have all my formatting everything that i need and all i would have to do is go through and replace the items in the table so once again i can do a control x but this time i’m going to say paste and merge formatting to take on the formatting of the table let’s do a couple more i’m going to select control x i’m going to do paste and merge formatting i’m going to carry on going through repeating this process for the rest of these agenda items so this now looks a lot more interesting and also a lot neater and more organized now that i’m using tables i’m just going to make a few further changes to these tables so i’m going to click in the second table in that second row i’m going to go up to the select group and select the row and i’m going to change the shading to green i’m going to do the same thing for the final table select the row and let’s change the shading to a yellow color and one thing you’ll notice is that with this table at the bottom we don’t have quite as hefty as schedule in the last part of the day and so i have a blank row at the bottom here that needs to be deleted and again this is a simple process you can either click in the margin to select the row alternatively click on the select rows button and then you can utilize your delete options so i’m going to say delete rows just to remove that and then finally at the top here we have an option to convert to an excel spreadsheet so what i could do is i could click in this table i’m going to say select table and click convert to excel spreadsheet and you can see what i get now i’m now working within essentially a mini excel window and if i click on the edit button it’s going to open that up in excel which then of course widens what i can do with this data because i have all of excel’s functionality to hand so it might be at this point that i choose to merge these cells so i’m going to say merge cells like so click on save and when i close the excel spreadsheet back down again you can see that those cells are now merged so it gives the table a bit of a different look and feel and it really depends what you want to do but this is a great way of having a table in onenote but having access to excel functionality so lots of options you have in there for organizing your data with tables that’s it for this module i will see you in the next one hello everyone and welcome back to the course in this module i want to start to introduce you to the concept of tagging in onenote i’m going to start out with the most basic tag that you can add and probably one that you’ll use most often and that is the to-do item tag now the to-do item is great if you want to create like a to-do checklist so for example for this project project artemis there are lots and lots of different tasks that need to occur before this project can go ahead anything from organizing which team members are going to be sent to the different locations to booking the training rooms organizing flights and hotels writing the training content all of those different kinds of things so in its most basic form what you can do in one note is you can add a list of items or to-do items utilize the to-do tag and then check them off once they’re done so let’s take a look at how this works so i’ve created a new section called to-do list and i’ve called this page to do items i’m going to click my mouse right at the top there and on the home ribbon in this tags group you’ll see that i have a to-do tag now what you also might notice is that to do also appears at the top of this tags list and that’s because it’s probably one of the most popular ones you’re going to use now there is a keyboard shortcut to insert this particular tag of control plus one and we haven’t covered tags yet you can see we have a lot of items in this big long list we are going to go through some of these so you understand what they all do and how helpful they can be for the time being we’re just going to concentrate on this first one so let’s click on to do and you’ll see that it enters in a placeholder with a little checkbox and i can then type in my to-do item so assign team members to locations if i hit the enter key you can see i get another to-do box hit enter again i get another one so on and so forth and i could carry on going adding my different to-do items and that’s pretty much all it is it’s a very simple little utility but it just allows you to keep track of the things that you need to do and once they’re done you can just click in the box to tick those off now you can make some very minimal modifications to how these to-do boxes look so if i right-click my mouse you can see i have options to uncheck the box i can also remove the tag entirely i’m going to talk to you about find tags a bit later on but the one i want to go into is customize tags so i’m going to select the to do tag at the top and i’m going to say modify tag so if i wanted to i could change the display name of this particular tag but i can also do things like change the symbol the font color and the highlight color so you have some limited customization options so for example if i click the symbol drop down you can see i can change to any of these symbols now i actually like having a check box but it might be that i want something that looks a little bit different maybe this green star check box and you can see in the preview below what that’s going to look like it might be that i want to change the font color so let’s change that to a dark green color and if i wanted to i could add a highlight now i don’t particularly want that i’m going to say none and one important thing to know is it says underneath customizations do not affect notes you’ve already tacked so if i click on ok and ok again you can see that the check boxes i’ve already added aren’t affected so i’m not getting that updated formatting but if i was to click somewhere else and then select to do from tags i’m going to get that new style but of course if i did have quite a long to-do list and i wanted to change the formatting i could just select the current tags jump up to my tags group and click the newly formatted to-do tag and that’s going to replace all of those now there’s a whole heap of other things that you can do with tags including the to-do tag which i’m going to show you a bit later on because we have a whole module dedicated to exploring all of the tags that you can see in here and using them in a meaningful way but for now that’s how you create a very simple to-do list with checkboxes that’s it for this module i will see you in the next one hi guys and welcome back to the course we’re heading steadily towards the end of section four in this section we’ve been taking a look at formatting tools and how you can organize your information within onenote effectively and no section on formatting would be complete if i didn’t run you through the options you have when it comes to spell checking nothing makes a document or a notebook look unprofessional quite like misspelt words particularly if you’re going to be sharing this notebook with your team colleagues or maybe even a manager you want to make sure that every time you create a page you do run through a spell check now i want to start out just by taking you into the backstage area just so you can see where all of your spelling options are because that’s really going to determine how you spell check your notebook so let’s go up to file and we’re going to go all the way down into our one no options and the section that we are interested in is the proofing section now i would advise you to jump into here and just review the options that you have turned on but the thing i want to draw your attention to is this section at the bottom so underneath here you can see that i have selected to check my spelling as i type and i’ve also got check grammar with spelling as well so what that basically means is that as i’m typing my notes in one note onenote is checking to make sure i’ve spelt words correctly and if i do spell something incorrectly it’s going to indicate that and i have an option to correct it as i go the same thing applies with grammar because i have this option selected as well now some people don’t like their applications checking their spelling as they go they’d rather just wait until the end and then spell check the entire thing and that’s entirely up to you if you do want to turn off that option make sure you select hide spelling and grammar errors now i’m happy with mine set as they are i’m going to click on ok and just show you what i mean so if i was to type a word let’s spell something incorrect i’m going to say microsoft instead of microsoft and you can see automatically onenote has recognized i’ve spelt that wrong and i have a red squiggly underline so if i right click my mouse you can see straight at the top it’s going to give me some suggestions of what i might have been trying to say and in this case it’s picked up that i probably wanted to say microsoft so i can click to make that correction i can choose to ignore or i can choose to add it to a dictionary now the add to dictionary option is really useful particularly for things like names so onenote won’t necessarily recognize your manager’s name and so might think that that’s an error when you type it into the page and if you’re always typing your manager’s name it is a bit annoying to have to go in and ignore the error each time so what you could do is add the word to the dictionary instead so that the next time you type it one note knows that that’s an actual word and it doesn’t highlight it as an error but in this case i’m going to select microsoft and you can see it updates that word so i’m going to double click to delete that out because i don’t need it but hopefully you get the idea so if you want to check your spelling and your grammar as you go just make sure you turn on those two little options now the alternative thing that you can do is you can spell check each of your pages at the end so if i jump up to the review tab you can see i have a spelling group here and the first option is spelling so let’s click that button and you can see it’s telling me straight away the spelling check is complete so essentially i’ve been pretty good here i haven’t got a misspelt word or a grammatical error on this page at all let’s click on ok to get rid of that now let me jump to a page where i know i do have some errors i’m going to go into my courses section group and on the onenote page let’s run our spell check again now this time you can see that i have the spelling pane opened on the right hand side and it’s picked up the word powerpoint and that’s because i’ve used a lowercase p within this word and it should really look like this and you can see that i’ve got some suggestions underneath which i can choose from so i’m going to say i meant powerpoint with a capital just to replace that word it’s then picked up the word won’t so you can see that i’ve missed out an apostrophe now as i’m going through you can also see that the word that i’m currently spell checking is highlighted in the notebook and this is a good opportunity for you to see the different visual indicators applied to different errors so because this is a grammar error as opposed to a spelling error the word has a blue double underline whereas spelling errors have that red squiggly underline so once again the suggestion i have here is correct i’m going to select it to replace it moves on to the next one and i can see here that this is actually a spelling error so this should say i can’t wait to dive into it so once again the suggestion here is correct i’m going to select to change it to weight and then i have another grammatical error once again i’ve missed out an apostrophe so i’m going to accept this suggestion and now my spelling check is complete now it’s worth noting with this spell check that you can only check one page at a time there isn’t any feature that allows you to define the scope of what you’re checking so i can’t say to one note check the entire notebook which would include all sections and all pages i just have to check each page separately so how you want to manage that whether you want to do it as you go or do it right at the end is entirely up to you now let’s do one final spell check i’m clicked on the schedule tab in the course plan group and i can already see here i have the word sharepoint repeated throughout this little table which is a red squiggly underline so it’s telling me that it’s a spelling error so i can jump back up to spelling i can see that once again it’s because i haven’t capitalized that p so i’m going to select the suggestion and replace that for each of these by simply clicking again there’s no way to replace them all in one go unfortunately so that’s it for this module and also for this section we’re going to be moving across into section 5 now where i’m going to show you some more tools available to organize your content so i’m looking forward to it i hope you will join me hi guys and welcome back to the course so now let’s take a look at some of the things that we’ve learned in this section in the windows 10 version of onenote so the first thing i’m going to do here is i am working in project sierra i’m on the to-do list section and i’m currently clicked on the monday page and currently i have a single note in there that says remember to call the bank now what i’m going to do here is i’m going to press enter i’m just going to add a bit of a title and i’m going to call this important things and what i want to do here is apply some formatting to this title and you’ll see as i highlight important things i get that little mini toolbar pop-up that’s going to give me some of those formatting options that i might find useful and if i click on the three dots it’s going to give me access to a lot more options as well it just so happens that the option that i want to use isn’t on this mini toolbar so i’m just going to select important things and go up to the home tab because what i want to do here is i want to apply one of those heading styles to really make this title stand out from the points below so i’m going to go all the way across this ribbon to where we have heading 1 click the drop down and i’m going to give this a heading 2 heading so once again when it comes to applying styles it works exactly the same way as onenote for desktop now what i want to do is i want to add some tags and again we’re working on our home ribbon and if we go over to this little check box item and click the drop down this is where we can find all of our tags now the list in onenote for windows is not as comprehensive as what you’ll find in that desktop app if you remember we have a very long list of tags to choose from but we have a few really important ones so the to-do list checkbox the important tag questions remember for later and also definition and of course if you want to you can jump into here and create your own custom tag so maybe i want to be able to tag contacts so i’m going to call this one contacts i’m going to select an icon now for this i’m going to jump to all icons and let’s see what we’ve got in here i’m going to select this one click on create it’s telling me my tag was created successfully so now if i click that drop down i should be able to find my newly created tag in here and of course right at the bottom i have the option to delete my custom tags which at the moment is only this context one now i don’t want to delete it so let’s just go back because the one that i want to choose is the to do tag and that’s going to give me that all important check box and then when i hit enter i can carry on going through and typing in my checklist items [Music] now if i wanted to create another list down here i’m going to say medium priority it might be that i want this to take on the same formatting as the important things heading so what i could do is i could jump up to the home tab and just apply heading 2 but i could utilize my format painter so i’m going to select important things because that contains the formatting i want to use and then on that home tab in the middle i have a format painter icon so let’s click it once to activate and then all i need to do is paint over my text to apply the same formatting hit enter and i can now enter my medium priority to do items like so and once again i could tag these if i wanted to i’m going to select both items jump up to my tags and this time i’m going to say that these are important now one other thing we took a look at in this section was utilizing spell check now with onenote for windows 10 if you go through all of these ribbon tabs then you won’t find an option on here for checking spelling and that’s because one note is set up to check your spelling as you type so for example if i was to go into here and make a blatant spelling mistake so let’s say i say [Music] like that once i click away then one note is going to highlight that to me by a red squiggly line letting me know that i have a spelling error just there so what i can do is right click go to proofing and it’s going to give me some suggestions i can also choose to ignore or add to the dictionary from here so i’m going to choose the correct spelling which is priority and it fixes that spelling error for me the same thing is going to apply with grammar now if you want to check what you have set up for your spelling settings if you go up to the three dots in the top corner and then choose settings and go to options if you scroll down you’ll see that underneath proofing you want to make sure that you have hide spelling errors toggled off this means that onenote is going to check as you type so if you know that you have a spelling error but onenote isn’t recognizing it it’s probably because you’ve got this setting toggled on so don’t forget to check that so that is it for this section i will see you in the next one if you’re not a subscriber click down below to subscribe so you get notified about similar videos we upload to get four free courses

Python Fundamentals: A Comprehensive Study Guide
Quiz (Short Answer)
What is the Python interpreter, and what is its role in executing Python code? The Python interpreter is a program that reads and executes Python code, line by line. It translates the human-readable code into instructions that the computer can understand and perform.
Briefly explain the difference between a code editor and an IDE (Integrated Development Environment). A code editor is a basic text editor with features for writing and editing code, such as syntax highlighting. An IDE is a more comprehensive tool that includes a code editor along with debugging, testing, and auto-completion features.
Why is “linting” important in software development, and how does it benefit the coding process? Linting involves analyzing code for potential errors and stylistic inconsistencies before execution. It helps catch syntax errors and ensures code adheres to style guides, making it cleaner and more maintainable.
What is Pep 8, and why is it important for Python developers to adhere to it? Pep 8 is the style guide for Python code, outlining rules for formatting and styling to ensure consistency across different codebases. Adhering to it promotes readability and collaboration.
Explain the concept of a variable in programming and provide examples of different data types that can be stored in variables. A variable is a named storage location in a computer’s memory used to store data. Data types that can be stored in variables include integers, floats, booleans, and strings.
What is the purpose of the len() function in Python, and what type of argument does it typically take? The len() function returns the length of a sequence, such as a string or a list. It takes the sequence as its argument and returns the number of items in the sequence.
Explain the use of escape characters in Python strings and provide a few common examples. Escape characters are special characters in strings used to represent characters that are difficult or impossible to type directly. Examples include n (newline), t (tab), \ (backslash), ” (double quote), and ‘ (single quote).
Describe the purpose and syntax of formatted strings (f-strings) in Python and explain their benefits over traditional string concatenation. Formatted strings (f-strings) allow embedding expressions inside string literals, making string formatting more readable and concise. Using an f-string, you can put variables and expressions inside curly braces {} within the string.
What is the difference between functions that “perform a task” versus those that “calculate and return a value”? Give an example of each. Functions that perform a task carry out actions, often with side effects, but don’t necessarily return a value (e.g., print(), which displays output on the console). Functions that calculate and return a value perform computations and return the result, which can then be used elsewhere in the program (e.g., round(), which returns a rounded number).
Explain the purpose and usage of a for loop and a while loop, highlighting the key differences between them. A for loop is used to iterate over a sequence (e.g., list, string, range), executing a block of code for each element in the sequence. A while loop is used to repeatedly execute a block of code as long as a specified condition is true, making it useful when the number of iterations is not known in advance.
Essay Questions

CPython execution: The course describes that CPython compiles Python into Python Byte code then passes the Byte code to the Python virtual machine to be converted into machine code and executed.
III. Fundamental Concepts Covered (Excerpt)
Variables: Used to store data in computer memory. Examples given include integers, floats, booleans and strings.
“we use variables to store data in computer’s memory here are a few examples I’m going to Define a variable called students underline count and setting it to a th000”
Data Types: Introduction to primitive data types (integers, floats, booleans, and strings) and type conversion.
“primitive types can be numbers booleans and strings”
“In Python we have a few built-in functions for type conversion we have int for converting a number to an integer we have float we have bull and stir or string”
“for all these types of numbers we have the standard arithmetic operations that we have in math let me show you so we have addition subtraction multiplication division but we actually have two different types of divisions”
User Input: Using the input() function to get input from the user and convert it to the correct type.
“we use the input function to get input from the user as an argument we pass a string this will be a label that will be displayed in the terminal you’ll see that in a second so let’s add X colon now this function returns a string”
Comparison Operators: Used to compare values to form a boolean expression.
“we use comparison operators to compare values here are a few examples so 10 is greater than three we get true so what we have here is a Boolean expression because when this expression is evaluated we’ll get a Boolean value that is true or false”
Conditional Statements: Demonstrate if, elif, and else statements for decision-making, along with the use of logical operators (and, or, not).
“in almost every program there are times you need to make decisions and that’s when you use use an if statement here’s an example let’s say we have a variable called temperature we set it to 35 now if temperature is greater than 30 perhaps we want to display a message to the user”
Loops: Explain for and while loops for repetition, including the range() function, break statement, and for…else construct.
“there are times that we may want to repeat a task a number of times for example let’s say we send a message to a user if that message cannot be delivered perhaps we want to retry three times now for Simplicity let’s imagine this print statement is equivalent to sending a message in a real world program to send a message to a user we have to write five to 10 lines of code now if you want to retry three times we don’t want to repeat all that code that is ugly that’s when we use a loop we use Loops to create repetition”
Functions: Defining custom functions, passing parameters (arguments), returning values, optional parameters, and variable number of arguments using *args.
“so far you have learned how to use some of the built-in functions in Python such as print round and so on in this section you’re going to learn how to write your own functions now you might ask but why do we even need to write our own functions well when you build a real program that program is going to consist hundreds or thousands of lines of code you shouldn’t write all that code in one file like we have done so far you should break that code into a smaller more maintainable and potentially more reusable chunks you refer to these chunks as functions”

Booleans: True or False values used for decision-making
Strings: Text surrounded by quotes (e.g., “Python Programming”)
7. What are functions in Python and how are they created?
Functions are reusable blocks of code designed to perform specific tasks. They are created using the def keyword, followed by the function name, parentheses for parameters (inputs), and a colon. The code within the function is indented. Functions can either perform a task (e.g., printing something to the console) or calculate and return a value.
Example:
def greet(first_name, last_name):
“””Greets a person by their full name.”””
return f”Hi {first_name} {last_name}”
message = greet(“Mosh”, “Hamedani”)
print(message)
8. How do loops work in Python, and what are the differences between for and while loops?
Loops allow you to repeat a block of code multiple times.
for loops: Iterate over iterable objects like ranges, strings, or lists.
for number in range(5):
print(number) # Prints numbers 0 to 4
while loops: Repeat a block of code as long as a specified condition remains true.
number = 100
while number > 0:
print(number)
number //= 2 # Integer division by 2
`break` statements can be used to exit a loop prematurely.

Keyword Arguments: Improve code readability by explicitly specifying the parameter name when calling a function (e.g., increment(2, by=1)).
Optional Parameters: Give a parameter a default value to make it optional (e.g., def increment(number, by=1)). Optional parameters must come after required parameters.
Variable Number of Arguments: Use an asterisk (*) to collect a variable number of positional arguments into a tuple.
Python Fundamentals for AI and Machine Learning
The sources provided focus on the fundamentals of Python programming and do not contain specific information about machine learning. However, they do establish that Python is a language used for AI and machine learning.
The course aims to equip learners to use Python confidently for AI and machine learning, along with web development and automation. Furthermore, a long-lasting career with high pay is available in AI and machine learning for those who learn Python.
Beyond what is in the sources, it is important to note that machine learning involves algorithms that enable computers to learn from data without explicit programming. Since the sources do not elaborate, it would be best to independently verify that information.
Python for Web Development
The provided source material does not offer specifics on web development. However, it does identify web development as one of the applications for Python. The course outlined in the source aims to equip learners to confidently use Python for web development, along with AI, machine learning, and automation.
Outside of the provided sources, it is important to note that web development typically involves creating websites and web applications using a combination of front-end and back-end technologies, but since the source does not elaborate, it would be best to independently verify that information.
Python for Code Automation
The sources identify code automation as one of the applications of Python. The course is designed to equip learners to confidently use Python for automation, along with AI, machine learning, and web development.
Outside of the provided sources, it is important to note that code automation involves using programming to automate repetitive tasks. However, since the sources do not elaborate, it would be best to independently verify that information.
Understanding Python Function Arguments
Here’s a discussion of function arguments, based on the sources:
Parameters vs. Arguments: A parameter is an input defined within a function’s definition, while an argument is the actual value provided for that parameter when the function is called.
Required Arguments: By default, all parameters defined in a function are required. If a required argument is missing when the function is called, Python will raise a TypeError.
Keyword Arguments: When calling a function, you can specify arguments using the parameter name, which can improve code readability. For example, increment(2, by=1) uses a keyword argument to specify the value for the by parameter.
Optional Parameters: To make a parameter optional, provide a default value in the function definition. For example, def increment(number, by=1) makes the by parameter optional with a default value of 1. If the caller omits the argument, the default value is used; otherwise, the provided value is used. All optional parameters must come after the required parameters in the function definition.
Variable Number of Arguments: You can define a function to accept a variable number of arguments using an asterisk (*) before the parameter name. This collects all positional arguments into a tuple, which can then be iterated over within the function. For example:
def multiply(*numbers):
total = 1
for number in numbers:
total *= number
return total
result = multiply(2, 3, 4, 5) # result will be 120
