Factorial of n is the product of all positive descending integers. Factorial of n is denoted by n!. For example:

1. 5! = 5*4*3*2*1 = 120  
2. 3! = 3*2*1 = 6  

Program:

n=int(input("Enter the number"));       

f=1

for i in range(1,n+1,1):

           f=f*i   

       

print("Factorial of",n," is ",f);     

OutPut:

Enter the number5

Factorial of 5  is  120

Enter the number3

Factorial of 3  is  6
