Ivan Levkivskyi <levkivs...@gmail.com> added the comment: You can use Iterator type, for example this works in mypy (didn't test in other type checkers):
def f() -> Iterator[int]: yield 42 In case you want annotate something specifically as Generator[int, None, None] (for example to use its .close() method), then you can create a generic alias: T = TypeVar('T') Gen = Generator[T, None, None] def f() -> Gen[int]: ... this is supported by mypy as well. ---------- nosy: +levkivskyi _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31700> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
