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 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]
