Or using your exact implementation, but subclassing AutoNumber from IntEnum:
class AutoNumber(IntEnum):
def __new__(cls):
value = len(cls.__enum_info__) + 1
obj = object.__new__(cls)
obj._value = value
return obj
def __int__(self):
return self._value
class Color(AutoNumber):
red = ()
green = ()
blue = ()
print(repr(Color.red))
---------- Run Python3 ----------
<Color.red: ()>
