FootyStats/footy ? reverse-engineered prompt

Build me a small football statistics project that lets me explore and analyze soccer data in Jupyter notebooks and also use the same logic from a Python module.

I want a clean starting notebook that walks through the basic background and shows how to load match data, calculate useful stats, and compare teams or players in a simple way. Please make it feel like a lightweight data analysis toolkit, not a big app, with clear examples, reusable functions, and a few tests so I know the main pieces work.

If there’s any current Python or pandas detail you need, look up the latest docs online. Keep the setup simple, and make sure the documentation is easy to follow so someone can open the notebook and start experimenting right away.
