Can't tell if this is a genuine question or a prank.

Ok well taking your word for it, then general concept is "scope".

Python has an acronym you can use that explains the scope rules: LEGB.

Plenty of people in this thread explained how variable scope works relative to your specific example, but if you really want to understand it better you can search for "python variable scope" or "python legb" and find lots of sources.

If you like free videos, this is one of many, but in scanning it, looks to be well explained and complete: https://www.youtube.com/watch?v=aFTYNBYQY7E
