 >>> import random
 >>> fee, fye, foe, fum = [random.random() for _ in range(4)]
 >>> fee, fye, foe, fum
(0.39415235335694276, 0.43533547827112462, 0.47106288849970501, 
0.87920678036897715)

I don't know pychecker well enough, but I think it ignores variables 
named _, so I think you could also just switch your n with _. 
Personally, I find the list comprehension much more readable.
