Crap. I should have read the doc string:
Type: builtin_function_or_method
Base Class: <type 'builtin_function_or_method'>
String Form: <built-in method permutation of mtrand.RandomState
object at 0xb77abbb4>
Namespace: Interactive
Docstring:
Given an integer, return a shuffled sequence of integers >= 0 and
< x; given a sequence, return a shuffled array copy.
permutation(x)
