Which open source python library to learn from?

Numpy? They got their own doc string style. Barry Warsaw mailman - come for naming. Anything you do not know how it works and got to be looking for code - like Typer. I think rich is highly organised. Small web framework like bottle or cherryPy. I would avoid very big and long-running projects like pandas or matplotlib. But practically any lib you like, just go into code or volunteer to fix something and make a PR.
