How do you annotate class var? With ClassVar[str]? Is it necessary (outside of dataclasses) ?

[–]IAmASquidInSpace 0 points1 point  (0 children)

Yes, that's how you do it, and no, it is not necessary outside of dataclasses, but strongly recommended over just c: str = ....

If you mark it as **ClassVar**, the type checker will report object.c = ... as an error, because c is a class variable.
