I have seen some people prefer to create a list of strings by using thing = list[str]() instead of thing: list[str] = []. I think it looks kinda weird, but maybe that’s just because I have never seen that syntax before. Does that have any downsides?

It is also possible to use this for dicts: thing = dict[str, SomeClass](). Looks equally weird to me. Is that widely used? Would you use it? Would you point it out in a code review?

    But I think that both are useless because you can put what you want in a list in python.

    You can say that about all type hinting, but assuming you actually adhere to the type hints, it’s a great tool to make python projects manageable.
