Yes, but without the need for multiple inheritance and separate
mixins ;-) Especially if the behaviour is enum-specific, e.g.:
class IETFStatusCode(IntEnum):
@classmethod
def from_statusline(cls, line):
return cls(int(line.split()[0]))
class HTTPStatusCode(IETFStatusCode):
NOT_FOUND = 404
class SIPStatusCode(IETFStatusCode):
RINGING = 180
Regards
Antoine.
