Write a Python function to calculate the factorial of a number (a non-negative integer). The function accepts the number as an argument 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):
return 1 if (n==0 or n==1) else n*fact(n-1)
fact(3)
