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.

The formula for factorial is n! = n(n-1) (n-2) (n-3) .... n . Here n is the number whose factorial is to be calculated. Factorial is the product of integer and all the integers below it.
It's important to note that the Numpy factorial function (AKA, numpy. math. factorial) only accepts integer values as an input. It will throw an error if you attempt to use this function on a Numpy array.
You can implement a factorial function in Python using one of several tools: for loops. Recursive functions. math.
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.
