Its not about where the count starts its about where it finishes. It finishes 1 item before the second index. so in this case you get the items at -3 and -2. If you specify a third parameter you can change the direction of the count thus: >>> great[-1:-3:-1] '!e' So now you get the characters at -1 and -2 (ie in reverse order) If you want them in original order starting at -3 just omit the -1: >>> great[-3:] 'me!'
