mapping function to vars

I need to map a function to several variables. I'm trying to use map
and lambda to do this. Here's my attempt...

#!/usr/bin/env python
from random import *

[fee, fye, foe, fum] = map(lambda n: random(), range(4))

print fee
print fye
print foe
print fum

....I'm essentially trying to map a function that takes no parameters to
a group of variables. This works, but pychecker complains about the
'n' parameter. Is there a better way to do this? TIA

from random import random
fee = random()
fye = random()
foe = random(),
fum = random()
[color=blue]

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.

Thanks! This is exactly what I was after :)
