HELP! Return Statement Debugging

[michael1789]

All functions which don't return (or yield) anything return None.

Sorry, my bad. Got it now. You aren't returning n. The function just ends, making it "fruitless".

while True:
    def absoluteValue(n):
        if n < 0:
            return -n
        elif n > 0:
            return
        else:
            print("Please key in a value greater or lower than 0 !! ")
            return n      """<------ Fixes it"""
     
    def main():
        y = input("Key in an integer : ")
        n = int(y)
        print("The Absolute Value of", y, " is ", absoluteValue(n))
     
    main()
