Question about function variables

So im trying to create a Tic Tac Toe game.. In the following code im trying to ask the user if he wants to play first or second. I want to ensure that he only input integers, and that the integers are between 1 and 2. However when i run this code, it says that first_or_second is not defined? Why is this, the user has just inputted what first_or_second is?? 

def Input():
    try:
        first_or_second = int(input("Would you like to go first or second? 1/2"))
    except ValueError:
        print("You can only input numbers!")

print("Welcome to a Tic Tac Toe game! You will play as X!")
Input()
if first_or_second not == 1 or 2:
    print("You can only input 1 or 2!")
    Input()
else:
    print("Ok youre playing as {}".format(first_or_second))

It's probably a scope issue, first_or_second is declared inside the Input() function, so its value is only accessible to other code within that function. Try declaring it before the Input function.

first_or_second is declared inside a function meaning the rest of your code doesn't have access to it. As Ben said, it's a scope issue.
