About the Python projects
Python is the number-one open source language by new projects: people write everything in it, from automation scripts to machine learning frameworks. Its low entry barrier produced the broadest ecosystem around — most tasks have several mature libraries to pick from.
This page collects Python tools, frameworks, and learning repositories. Cards show stars, the license, and a short description; each project page adds an architecture walkthrough with code samples.
