I don't know, it feels like your inspiration for this post is stronly based on https://realpython.com/python-testing/. I was visiting the side yesterday it's kind of interesting to see such resemblance. Same analogy (lights gone), same code ...

TestStringMethods is straight copied from https://docs.python.org/3/library/unittest.html.And yet you covered just a fraction of what's important.

Your work on Julia is still strong, but with this vast amount of banal work on Python, I don't know if I should unfollow.
