Like a lot of us, I learned Python by Googling around for years and never really read a full book. I finally decided to write the one I wish I had.
It's called The Python Codex – free, open, and you can read it all here: https://py.qizhen.xyz/en/
I framed it as a story (a journey to the planet Pythora) but it's a serious tutorial underneath, in 5 parts:
Fundamentals
Functional Programming
OOP
Data Structures & Algorithms (with interview questions)
Python in the wild – viz, web, networking etc.
It's still a work in progress, and you can comment or even hit "Edit this page" on any page. Would love feedback from learners – what's confusing, what's missing?
Hope it helps someone here.
