Python: Factorial of a number using itertools module

Python Itertools: Exercise-20 with Solution

Write a Python program to find the factorial of a number using the itertools module.

Sample Solution:

Python Code:

import itertools as it
import operator as op

def factorials_nums(n):
    result = list(it.accumulate(it.chain([1], range(1, 1 + n)), op.mul))
    return result;
    
 
print("Factorials of 5 :", factorials_nums(5))
print("Factorials of 9 :", factorials_nums(9))

Sample Output:

Factorials of 5 : [1, 1, 2, 6, 24, 120]
Factorials of 9 : [1, 1, 2, 6, 24, 120, 720, 5040, 40320, 362880]
