factorial of number program in python code example
Example 1: python calculate factorial
def factorial(n):
fact = 1
for num in range(2, n + 1):
fact = fact * num
return(fact)
Example 2: factorial in python
def fact(n):
if n==0 or n==1:
return 1
else:
return n*fact(n-1)
print(fact(4)) #4 is the sample value it will returns 4!==> 4*3*2*1 =24
#OR
import math
print(math.factorial(4))
