Since I like puzzles, here is a working LenientStrEnum:
class LenientStrEnum(str, Enum):
#
def __init__(self, *args):
self._valid = True
#
@classmethod
def _missing_(cls, value):
logger.warning(
f"[{cls.__name__}] encountered an unknown value!\n"
f"Luckily I'm a LenientStrEnum, so I won't crash just yet.\n"
f"You might want to add a new case though.\n"
f"Value was: '{value}'"
)
unknown = cls._member_type_.__new__(cls, value)
unknown._valid = False
unknown._name_ = value.upper()
unknown._value_ = value
cls._member_map_[value] = unknown
return unknown
#
@property
def valid(self):
return self._valid
`_member_map_` is not guaranteed, but is unlikely to change.
