This error was added in https://bugs.python.org/issue33018 . See some discussion on that issue. Note that first arg needs to be a type (i.e. instance of `type`) to avoid this error: [ins] In [41]: class C(ABC):0 [ins] In [42]: issubclass(dict, C) Out[42]: False [ins] In [43]: issubclass('', C) # TypeError: issubclass() arg 1 must be a class [ins] In [44]: issubclass(typing.Dict, C) # same error as above ---------- nosy: +andrei.avk _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45326> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
