It is not specific to typing. >>> isinstance(1, (int, 1)) True >>> isinstance(1, (1, int)) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: isinstance() arg 2 must be a type or tuple of types >>> issubclass(int, (int, 1)) True >>> issubclass(int, (1, int)) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: issubclass() arg 2 must be a class or tuple of classes isinstance() and issubclass() with tuples always stopped on first positive match. I don't think there is need to change this. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44932> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
