Python 3 Intermediate

Comprehensions, OOP, files, and the standard library rabbit hole.

Level up with list comprehensions, exceptions, classes, modules, file I/O, decorators, and generators. Covers the broad middle ground every working Pythonista needs — with enough quirks to keep you humble.

Learn with Ada, your AI coding mentor — ask questions or tap I’m stuck in any lesson for a nudge without spoilers.
