Oh, I forgot to mention that flufl.enum has an alternative API that's fairly close to this, although it does not completely eliminate DRY[1]:
from flufl.enum import make make('Animals', ('ant', 'bee', 'cat', 'dog')) <Animals {ant: 1, bee: 2, cat: 3, dog: 4}>
You can also supply the elements as a 2-tuples if you want to specify the values. An example from the docs providing bit flags:
def enumiter(): ... start = 1 ... while True: ... yield start ... start <<= 1 make('Flags', zip(list('abcdefg'), enumiter())) <Flags {a: 1, b: 2, c: 4, d: 8, e: 16, f: 32, g: 64}>
Cheers, -Barry [1] The first argument is currently necessary in order to give the right printed representation of the enum.
