Learn how to access Python dictionary values by key using square brackets, differentiate from lists, and see how dictionaries hold multiple data types.

Capture and store user input with the Python input function, assign it to a variable, and display a personalized hello to show how input is captured and reused.

Explore Python conditional statements, using if, elif, and else to control program flow, compare values with equality and inequality, and format code with colon and indentation in a code editor.

Master the python for loop to iterate a devices list and perform operations. Combine for loops with if statements to filter items into a switches list and print results.

Learn to access and manipulate file contents in Python by creating, opening, reading, writing, and appending files, then storing data in a list and closing the file.

Learn how to write text to files using Python by building a script that opens a devices text file, inputs device names, appends items, and closes the file.

Set up and manage Python development environments by creating and activating virtual environments, installing and isolating packages with pip, and sharing a requirements file to reproduce setups.

Explore the REST API constraints that shape the client-server architecture, uniform interface, statelessness, cacheability, layered system, and on-demand capabilities, and learn how these constraints enhance performance, scalability, and reliability.

Explore how webhooks enable real-time, event-driven communication between web applications, allowing automatic data delivery and seamless integration with payment gateways, email marketing, and syncing to external databases and data warehouses.

Explore REST payloads, including how requests and responses carry data, with JSON and XML formats; learn how GET retrieves data and how POST, PUT, and batch requests include payload data.

Install curl on Windows and learn to use it for transferring data to and from networking devices remotely, with get, post, put, patch, and delete requests and api examples.

Learn to use a books library api with endpoints, authentication, and http methods like get, post, put, and delete, testing responses in json or yaml.
