If the argument is not int then make it int!

Hi !
I have to write a function named Countdown:

def countdown(n):
    while n > 0:
        print(n)
        n = n - 1
    print('Blastoff!')

Now if I enter a non-integer value and I want Python to change it to int value how should I get Python to do that?

I treid with this:

def countdown(n):
    if n not int(n):
       n=int(t) 
    while n > 0:
        print(n)
        n = n - 1
    print('Blastoff!')

What is wrong with this code?
