>>> import enum
>>> class M(enum.EnumMeta):
...     def __contains__(self, value):
...         print("checking", value)
...         return super().__contains__(value)

>>> class Colors(enum.Enum, metaclass=M):
...     red = 1
...     green = 2
...     blue = 3
... 
>>> Colors.red in Colors
checking Colors.red
True
