TL;DR Changes may be coming to Enum str() and repr() -- your (informed) opinion requested. :-)
Python-Dev thread [0], summary below:
As you may have noticed, Enums are starting to pop up all over the stdlib [1]. To facilitate transforming existing module constants to IntEnums there is `IntEnum._convert_`. In Issue36548 [2] Serhiy modified the __repr__ of RegexFlag: >>> import re >>> re.I re.IGNORECASE I think for converted constants that that looks nice. For anyone that wants the actual value, it is of course available as the `.value` attribute: >>> re.I.value 2 I'm looking for arguments relating to: - should _convert_ make the default __repr__ be module_name.member_name? - should _convert_ make the default __str__ be the same, or be the numeric value?
After discussions with Guido I made a (largely done) PR [3] which: for stdlib global constants (such as RE) - repr() -> uses `module.member_name` - str() -> uses `member_name` for stdlib non-global constants, and enums in general - repr() -> uses `class.member_name` - str() -> uses `member_name` The questions I would most appreciate an answer to at this point: - do you think the change has merit? - why /shouldn't/ we make the change? As a reminder, the underlying issue is trying to keep at least the stdlib Enum representations the same for those that are replacing preexisting constants. -- ~Ethan~ [0] https://mail.python.org/archives/list/python-...@python.org/message/CHQW6THTDYNPPFWQ2KDDTUYSAJDCZFNP/ [1] I'm working on making their creation faster. If anyone wanted to convert EnumMeta to C I would be grateful.
