CodeForces gives you programming problems and contests. You can choose to solve them in many different languages including Python.
Once you get an account, go to problem sets and sort by solved from “highest to lowest”. This will give you the easiest problems first.
I have made just a little progress. But I am hoping to do this on a daily basis. You can see my progress: codeforces.com/profile/GadgetNate
