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.

Solution

  • 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.
