return is only used inside a function, it makes no
sense outside (and is a syntax error). Its purpose
is to return a value to the caller of the function.

Any time you want to get a value back from a function
you must use return (or the slightly more esoteric 'yield')
Otherwise you will receive the default return value of None.
