In the case of a single program or script, I would agree that it is unimportant that your function return anything if this is not needed.

However, since this is a module, and intended for re-use, the function may be used in other situations that you might not anticipate.

In this case, I believe that any function should return at minimum a 1 or 0 to indicate success/failure. Of course, as others have very astutely pointed out, your function does this anyways.
