Python Write Better Python Cleaner Code Operator Spacing

Again for the "Fix the spacing . . ." challenge, there's an error that I don't see existing.

I have received the: "Bummer! Your file has 1 error(s) on line(s) 15: no newline at end of file." error again. I don't see why or how this is happening. I checked for a newline and there doesn't seem to be one and yet, I keep getting an error! What's going on?

starter.py
numbers = [1, 2, 3, 4, 5]


def add(num1, num2):
    return num1 + num2


def subtract(num1, num2):
    return num1 - num2


def mathy(num1, num2):
    up = add(5 + 7, 7 + 9)
    down = subtract(6, 3)
    return add(up, down)

The challenge is looking for an empty blank line at the end. Add a new line after line 15 with no spaces on it.

Thank you.
