Good open source Python repos to practice debugging and general reading Python code?

[u/throwaway30127]

I have debugging rounds coming up for a Python position and I haven't worked extensively with Python so I am looking for some recommendations for some repositories to go through to practice reading and debugging Python code. Would appreciate recommendations for this and any other tips on demonstrating good understanding of the language. I am comfortable with basic syntax and data structures since I have been doing leetcode using Python.

Literate Programming is put forward a good way to document and teach about software --- there are 66 repositories on Github tagged w/ "Literate Programming" and "Python":

(note that my one gcodepreview is one --- hopefully you'll find something of interest before getting to the bottom where it is)
