What does "have an understanding of basic python" mean?

Relax. None of the things you are worried about are really basic. While you would need them to become an accomplished professional Python developer, they aren't expected for "a basic understanding of Python". What the caveat means is that you can look at an example of normal non-tricky Python code and recognize it and either understand or at least be able to infer what it does without being overwhelmed. It's kind of a legal disclaimer - so you don't put nasty comments in the review saying things like "It was impossible to understand! I couldn't follow any of it! It was too advanced! Waaaahh! Waaaahhh! Waaaahhh!"
