Because - from a semantic POV -  the real error is not that you're
trying to divide zero by zero, but that you failed to pass any
argument. FWIW, I'd personnaly write avg as taking a sequence - ie,
not using varargs - in which case calling it without arguments would a
TypeError (so BTW please s/Value/Type/ in my previous post).
