You cannot prevent user from entering as many digits he want, but you can always check the size, and prompt the user to reenter if it exceeds it.

a=10001
while a > 9999 :
    a = int(input("Enter A Integer less than 9999: "))

Of course you would need exception handling if he passes a string instead of number.
