Consider using flake8, pylint or black

[bittner]

The code base is nice and small enough to run QA tools over it to enforce code quality without a lot of pain. I suggest you try out flake8, pylint or black.

Flake8 is somewhat the standard option (and arguably the minimum requirement), and luckily there is not a lot for you to do to make it pass:
