Python

What Python is, how to install it, and how to run your very first program.

Make decisions and repeat work with if/elif/else, for, and while.

The four built-in collections — what they are, when to use which, and how they compare.

Object-oriented Python: classes, instances, methods, dunder methods, inheritance, encapsulation.

Read and write files safely, handle exceptions, and understand the `with` statement.

Organize code into modules, install third-party libraries, and isolate projects with virtual environments.

Concurrency without threads — async/await, the event loop, and when (and when not) to use them.

Build a typed, async, OpenAPI-documented Python REST API in minutes.
