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
>>> 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.
