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.On Tue, Apr 20, 2021 at 7:59 AM Ethan Furman <et...@stoneleaf.us> wrote: > urllib.urlencode currently uses `str()` on its non-bytes objects before > encoding the result.
