I'd guess it is totally up to the object, since str() calls `__str__` and format() calls `__format__`. Of course this now begs the question whether those enums should perhaps change their `__format__` to match their `__str__`...? But that would not suit your purpose. Then again, how would one get the pretty IntEnum-specific representation in a format- or f-string? I guess f"{flag!s}" would work.

urllib.urlencode currently uses `str()` on its non-bytes objects before encoding the result. This causes a compatibility break when integer module constants are converted to IntEnum, as `str(IntEnum.MEMBER)` no longer returns the integer representation; however, `format()` does still return the integer representation.
The fix is to add a separate branch to check if the argument is an Enum, and use the value if so -- but it got me wondering: in general, are there differences between calling str() vs calling format() on Python objects?
