Explanation: Python is a programming language. Numpy is a library for python that makes it possible to run large computations much faster than in native python. In order to make that possible, it needs to keep its own set of data types that are different from python's native datatypes, which means you now have two different bool types and two different sets of True and False. Lovely.

Mypy is a type checker for python (python supports static typing, but doesn't actually enforce it). Mypy treats numpy's bool_ and python's native bool as incompatible types, leading to the asinine error message above. Mypy is "technically" correct, since they are two completely different classes. But in practice, there is little functional difference between bool and bool_. So you have to do dumb workarounds like declaring every bool values as bool | np.bool_ or casting bool_ down to bool. Ugh. Both numpy and mypy declared this issue a WONTFIX. Lovely.

What years of dynamic typing brainrot does to mf

I currently work on a NodeJS/React project and apparently I'm going to have to start pasting "'any' is not an acceptable return or parameter type" into every damned PR because half the crazy kids who started programming in JavaScript don't seem to get it.

For fucks sake, we have TypeScript for a reason. Use it!

if you have a pipeline running eslint on all your PRs (which you should have!), you can set no-explicit-any as an error in your eslint config so it's impossible to merge code with any in it

+1 if you can have automated checks do part of your reviews for you, it's a win. I never comment about code style anymore, if I care enough I'll build it into the lint config
