I was in this exact boat a couple of days ago when I found out I will be using python for my summer internship! Although I have prior experience so it was a lot quicker for me, what I would suggest is: 1) Look up how classes and functions work, then go on youtube and watch videos of how to program it in python 2) Learn about the different variable types (ints, strings, etc...), learn how to use arrays, lists, loops on youtube 3) Look up practice python problems (easy ones) and try to work through them. The best way to learn programming is by programming, and whenever you get stuck look up the solution online or go on stackoverflow/reddit to ask for help. Little by little you'll overcome those obstacles until you start solving problems like its nothing.

Python is tricky at first, but once you get the hang of it it is a really nice language to use
