Why does this simple python function only work once

I want to create a simple counter so i created this function:

count = 0

def add(count):
    count += 1
    print(count)

and if re-called the count goes up to 1 but if I recall it again it stays at 1. I also tried to output the count variable outside of the function after recalling it but that led to a constant output of 0

The count variable in your function has a different scope to the count variable in the rest of your script. Modifying the former does not affect the latter.

You would need to do something like:

def add(count):
    count += 1
    print(count)
    return count

count = 0
count = add(count)
count = add(count)
