Furthermore, you could define methods/fields on enum values, like Java's enums.
E.g.: Errno.EBADF.strerror() -> 'Bad file descriptor'
Easily adapt to additional fields:
class Protocol(Enum):
HOPOPT = 0, "IPv6 Hop-by-Hop Option"
ICMP = 1, "Internet Control Message"
IGMP = 2, "Internet Group Management"
@property
def value(self):
return self._value[0]
@property
def description(self):
return self._value[1]
