Python program to find the factorial value of given number

Write a Python program to accept a integer number form user and find the factorial value of input number.

The factorial of a number is the product of all the integers from 1 to that number. For example, the factorial of 6 is 1*2*3*4*5*6 = 720 . Factorial is not defined for negative numbers, and the factorial of zero is one, 0! = 1 .

Sample:

Input : 5

Output : 120

num=int(input("Enter any Number : "))
fact=1
for a in range(1,num+1):
    fact=fact*a
print("Factorial of ",a," is : ",fact)

Enter any Number : 5

Factorial of  5  is :  120
