I just wanted to throw in a couple of ideas for you on this subject.
These are the ways I would personally think of going about this
problem:
>>> ''.join([s[n] for n in range(len(s)-1, -1, -1)])
'rac'
Which looks a bit fugly but is nice and short if you can manage list comps.
and now my favourite

What I'm getting at here is that, by changing index, we can change
which letter we are looking at. And index is a number, which means
it's easier

What is vehicle[index] ?

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

Hi, remember that the condition for the while has to be true. When does
index >= index_zero stop being true???

Hello:
I am trying to write a code (this is an exercose from
a book). The goal is to write a program that takes a
string and outputs the letters backward, ine per
line.
Ok. I did a test first, by writing a code with
numbers:
a=0; b=10
while a<=b:
print b
b -= 1
Here the output is:
10
9
8
20 matches
