You can dispatch on collections.abc.Sequence. @functools.singledispatch def f(a: collections.abc.Sequence) -> None: pass But MyPy complains about this: error: Missing type parameters for generic type "Sequence" MyPy requires parametrized generic (like collections.abc.Sequence[int]), but singledispatch() does not work with it. ---------- components: Library (Lib) messages: 409295 nosy: gvanrossum, kj, rhettinger, serhiy.storchaka priority: normal severity: normal status: open title: Conflict between using annotations in singledispatch() and MyPy versions: Python 3.10, Python 3.11, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46191> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
