PR27648 fixes this, but it also breaks test_abc.test_issubclass_bad_arguments so it's not quite right. I don't know this area, but I think the problem is in the place the PR changes, and that the issue is due to this difference in the type of __subclasses__ between C and Meta2: >>> class C: pass ... >>> from abc import ABCMeta >>> class AbstractMeta(type, metaclass=ABCMeta): pass ... >>> class Meta2(AbstractMeta): pass ... >>> C.__subclasses__ <built-in method __subclasses__ of type object at 0x7f96bf5040b0> >>> Meta2.__subclasses__ <method '__subclasses__' of 'type' objects> ---------- versions: +Python 3.10, Python 3.11, Python 3.9 -Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36881> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
