Thanks for the prompt replies. But I am still confused. This is what confuses me.... The first time you call the function, say with f(23), after the function ends, y no longer equals None. Therefore, calling f again, this time like this f(24), should make y equal [23,24], because the 'if y == None' test fails, or at least I think it fails, because y.append(x) added something that was not equal to None during the previous call.
