Hoffman,

I am a newbie at python and programming in general so excuse me if I'm wrong.  In your example, you had

while index >= index_zero:


which I believe to not be what you intended as you are essentially saying:

while "last letter of vehicle" >= "first letter of vehicle"


"e" is respectively "less than" "v", so that is why your code never executes.  You probably mean for the index to actually be the index, not the last letter.  "index -= 1" is illegal as the variable points to a string, which can not be subtracted from.  Hope I was of help!
