New submission from theeshallnotknowethme <nohackingofkrow...@gmail.com>:
When I tried using `isinstance` with a type (e.g. `bool`) as the 1st argument and a parameterized generic in a tuple (e.g. '(`bool`, `list[bool]`)') as the 2nd argument, it raised a `TypeError`, 'isinstance() argument 2 cannot be a parameterized generic'. But when I did the same thing in `issubclass`, it returned a boolean and did not raise any `TypeError`s. Using `isinstance` with an object as the 1st argument and the same tuple 2nd argument also returned a boolean, and did not raise any `TypeError`s. Is this expected behaviour, or should this be fixed? This was tested in Python 3.10.0rc1 in a 64-bit system. ---------- components: Tests, Windows messages: 399717 nosy: February291948, paul.moore, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: `issubclass` and `isinstance` doesn't check for all 2nd argument types type: behavior versions: Python 3.10 _______________________________________ 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
