How can I represent an 'Enum' in Python?

Answer 1

The new standard in Python is PEP 435, so an Enum class will be available in future versions of Python:

>>> from enum import Enum

However to begin using it now you can install the original library that motivated the PEP:

$ pip install flufl.enum

Then you can use it as per its online guide:

>>> from flufl.enum import Enum
>>> class Colors(Enum):
...     red = 1
...     green = 2
...     blue = 3
>>> for color in Colors: print color
Colors.red
Colors.green
Colors.blue
