backports.strenum 1.3.1

A backport of (copy and paste from) python 3.11’s StrEnum class for >=3.8.6:

See the design discussion, and Ethan Furman’s first and second PR with this implementation.

A slightly different implementation would likely be compatible with lower python versions; PRs are welcome if they pass the test suite. The existing (reference) implementation should still be the one used on supported versions.

Install with pip install backports.strenum, and use with:

import sys

if sys.version_info >= (3, 11):
    from enum import StrEnum
else:
    from backports.strenum import StrEnum

class MyStrEnum(StrEnum):
    POTATO = "potato"
    ORANGE = "orange"
    SPADE = "spade"

MyStrEnum.POTATO == "potato"  # True
MyStrEnum.ORANGE.upper() == "ORANGE"  # True
str(MyStrEnum.SPADE) == "spade"  # True

From version 1.3.0, this package cannot be installed on python >=3.11. It shouldn’t be used on them anyway. Make sure that in your package, this is a conditional dependency.
