Sorry if this question is incredibly easy to answer, or I sound like an idiot. I'm wondering how I would execute a script in one file, pygame event loop, blits, etc, then switch to another file, SelectWorld.py, which has it's own event loop, and blits, and etc. If I just call it's main function, does it create any slowdown because I still have the original file open, or am I fine just doing that? SelectWorld.transition() sort of thing. Thanks in advance.
Turns out the answer to this was painfully simple, and I asked this back when I was just learning Python. There is no speed downgrade from just calling a function from another file and letting it do all the work. Thanks for all the answers, guys.
