How come when I ask it to print i[2:4] from an inputted string it
gives me the letters between two and four
But when I ask it to print i[-1:-4] it does not print anything.

Hi!
I am using a suggestion from this list to handle calling different
functions conditionallly based on user input. What I'm trying to do is
have functions that are 'configurable' in the sense that a choice from

approach that has been mentioned b
