def myfun():
    num=int(input("Enter a number: "))
    factorial=1
    if(num<0):
        print("Factirial does not exist for negative numbers")
    elif(num==0):
        print("Factorial of 0 is 1")
    else:
        for i in range(1,num+1,1):
            factorial=factorial*i
        print("The factorial of ",num," is ",factorial)
              
if __name__=="__main__":
    myfun()
