Because the range is counting forward from -1 (the last element) onward, and since there's nothing after the last element, it can't print anything. It's the same as typing range(5,2) for example. If you want it to give you the letters beteen -1 and -4 backwards, type i[-1:-4:-1] (I'm not sure that works in older Pythons). If you need the last 4 letters, type i[-4:].
