Python program to calculate the factorial of a number using while loop

num=int(input("Enter a number: "))
fact=1
a=1
while(a<=num):
    fact=fact*a       #fact*=a
    a=a+1             #a+=1
print("The factorial of",num,"is",fact)

    Output 1:
             Enter a number: 4
             The factorial of 4 is 24
    Output 2:
