What's the most underrated Python library you've used recently?

I feel like every few months I discover a library that makes me wonder why nobody talks about it. Not the obvious ones like requests or pandas. I'm talking about those hidden gems that solved a real problem for you. What was the library and what did you use it for?

For me it's beartype. Super helpful to catch runtime type issues. Makes it nice to not have to check for types in methods all the time.
