# Creating an enum (Python 2.4 through 3.3)
Enums have been backported from Python 3.4 to Python 2.4 through Python 3.3. You can get this the enum34 backport from PyPI.
pip install enum34
Creation of an enum is identical to how it works in Python 3.4+
from enum import Enum class Color(Enum): red = 1 green = 2 blue = 3 print(Color.red) # Color.red print(Color(1)) # Color.red print(Color['red']) # Color.red
Enums are iterable:
class Color(Enum): red = 1 green = 2 blue = 3 [c for c in Color] # [<Color.red: 1>, <Color.green: 2>, <Color.blue: 3>]
Enums were added to Python in version 3.4 by PEP 435.
