Hey email in plain text in the future, HTML is not kind to mobile screens and in general you should plaintext reply to tech lists.
All list indices start from 0. But you don't get the last value. So slice[1:5] would skip the first char and then include the next 3. It's the same as range. Range(1,100) returns 1,2,....,99.
Hope that helps
