Due to the nature of `str`, if an Enum tries to mixin the str type, all of it's members will be strings -- even if they didn't start out that way:
class MyStrEnum(str, Enum):
tuple = 'oops',
okay = 'correct'
>>> list(MyStrEnum)
[<MyStrEnum.tuple: "('oops',)">, MyStrEnum.okay: 'correct'>]
The StrEnum class will have a check to ensure that each value was already a string, or can be converted to a string via
str(bytes, encoding, errors)

From Serhiy Storchaka: --------------------- The only exception is StrEnum -- overriding __str__ of str subclass may be not safe. Some code will call str() implicitly, other will read the string content of the object directly, and they will be different. |
