Intializing return value to 0

[loomski]

This is a pretty choppy way to do this but I'm not sure why you set the value of num to 0 and then added 1 to it before even checking to see if it equals to 0 first. I rewrote what I (think?) you originally meant:

def running_average():
    total = 0
    num_values = 0
    average = 0
    while True:
        value = input("Enter an integer: ")

        if value == "done":
            break
        else:
            total += int(value)
            num_values += 1
            average = total / num_values
    return average


#print(running_average())

When it says you should initialize your return value to 0, it doesn't mean to literally return 0, but instead, you see how you're returning running_average? What it means is in your first declaration of running_average, you should set it to 0.
