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
