Best way to randomize a list of strings in Python

>>> import random
>>> x = [1, 2, 3, 4, 3, 4]
>>> random.shuffle(x)
>>> x
[4, 4, 3, 1, 2, 3]
>>> random.shuffle(x)
>>> x
[3, 4, 2, 1, 3, 4]

Looks like this is the simplest way, if not the most truly random (this question more fully explains the limitations): http://docs.python.org/library/random.html#random.shuffle
