As someone who has written some Python at work, whenever I need to work on some code without type hints, I spend way too much time trying to figure out what all the parameter types should be for functions. I can't be the only one doing this though, I've seen functions that assume their inputs are strings receiving
pathlib.Pathon some uncommon branch that sure enough errors on some obscure user inputs.I've been pushing mypy hard though. It's not perfect, but it works well enough that it's still worth using over not using. The biggest pushback has actually been from the amount of time we'd have to spend fixing type-related bugs instead of developing new features.
I have the same problem. Any time I use a dynamically typed language, whatever time I save not specifying the type, I’ll lose immediately when I have to hunt down what sort of data this function expects or chase down some error that a compiler would have caught in a statically typed language.
