Factorial in numpy and scipy

How can I import factorial function from numpy and scipy separately in order to see which one is faster? I already imported factorial from python itself by import math. But, it does not work for numpy and scipy.
You can import them like this: In [7]: import scipy, numpy, math In [8]: scipy.math.factorial, numpy.math.factorial, math.factorial Out[8]: (<function math.factorial>, <function math.factorial>, <function math.factorial>) scipy.math.factorial and numpy.math.factorial seem to simply be aliases/references for/to math.factorial, that is scipy.math.factorial is math.factorial and numpy.math.factorial is math.factorial should both give True.
