[Python-ideas] Iterate through members of enum.Flag

10 Sep 2021

      My proposal is that iterating through a member of a Flag enum will return all the constituent members.

Demonstration Setup:

class FlagEnum(enum.Flag):
    A = enum.auto()
    B = enum.auto()
    C = enum.auto()

FlagCombo = FlagEnum.A | FlagEnum.B

My proposed change would cause the following to occur:
...
...
...
print(list(FlagCombo))
[FlagEnum.B, FlagEnum.A]
print(list(FlagEnum.A))
[FlagEnum.A]
Compared to the current implementation:
...
...
...
print(list(FlagCombo))
Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
TypeError: 'FlagEnum' object is not iterable
What do you all think?
