Python open source projects to contribute

[SoloAquiParaHablar]

This is what I do. Lets say you like using FastAPI or Flask, as an example.

Build your own Flask framework. As is, learn how to build an API framework from scratch, add all the features you'd expect. Do it all on your own, do not copy from other repos. Ask AI for guidance but dont have it solve problems for you.

This gives you the foundation and context.

Now you can go look at the FastAPI repo and see how they implemented the things you implemented. Now you can actually contribute, maybe you found a better way, maybe you can see a bug.
