declare python enum without value using name instead

Question

Is there any way in python to declare an enum's variables without values?

The syntax that works:

from enum import Enum
class Color(Enum):
  Red = 'Red'
  Blue = 'Blue'
  Green = 'Green'

Since for this case the enum values are the same as the variable names, I'd like to avoid duplication.

Something like this maybe:

from enum import Enum
class Color(Enum):
  Red
  Blue
  Green

This is why enum.auto() is a thing, so you don't need to write values explicitly.

from enum import Enum, auto
class Color(Enum):
  Red = auto()
  Blue = auto()
  Green = auto()

You can also do print(Color.Red.name) to retrieve the name of the member :D
