Or if you prefer: Python identifies positions between characters,
rather than characters. And I agree that it's better than the
alternative - in fact, I wish other systems could work the same way
(eg Bible references). If you think about position 0 being the very
beginning of the string, and position len(s) being the very end, then
you slice the string from position to position and take the characters
between. When you index the string for a particular character, you aim
at a position and take the character after it.
