Grad student requesting help to refine/optimize my Python code

I've been self-teaching myself Python and would love some feedback on how to refine/optimize my code for a few scripts. I'm somewhat new to computer programming so I'm just not familiar with best/optimal practices if that makes sense. I imagine we would walk through a few of my scripts and you could provide feedback/tips/suggestions. I have some CS friends who could help, but I'd rather not be a burden to them. Willing to pay $20/hour (I'm poor...)!
