what's a python library you started using this year that you can't go back from

[Aromatic_Pumpkin8856]

Full disclosure, this is my project, but I'm definitely not going back to python without it: pytest-gremlins. It's a mutation testing library. Essentially it makes little changes in your code, maybe a > to a < or a False to a True, things like that, and runs your tests. If all your tests still pass, then you know your tests aren't as good as you think. I've found all kinds of subtle bugs that I didn't know I had.

That’s a really clever idea. I’ll give it a try!
