Documentation

Doc/library/enum.rst near line 537 reads:

Flag.__iter__() is new in Python 3.11, as already noted in typeshed and as may be verified using the following script:

from __future__ import annotations
from enum import (
        auto,
        Flag,
        )

class SomeFlag(Flag):

    A = auto()
    B = auto()
    C = auto()

if __name__ == '__main__':

    combined = SomeFlag.A | SomeFlag.B | SomeFlag.C
    # this works in Python 3.11, but not in Python 3.10 (no '__iter__()'
    # method)
    for flag in combined:
        print(flag)
