I have read about loops, strings, tuples. I am taking this class on distance education and I am lost with this assignment. I have read what Tony has wrote and that does me no good. I do not understand what he is talking about. I understand how slicing works and what the numbers mean. I know what the -1 and such like that mean. I know what the len function does. I am wasting you guys time.

I am very new to programming and I have an assignment to have a raw_input string that is inputted by the user and then is printed backwards. Can anyone help me? I can get it to print regular but backwards in not working.
I guess that I shouldn't give code if this is for an assignment, but if
you are using Python 2.4, then try seeing what the "reversed()" built-in
function does. If you're not using Python 2.4, then read up about
"slices" - which is when you get subsections of a string (e.g.
"tony"[2:4] is "ny"). You can pass a 'direction' in a slice as well.
It might also help to have a better feeling for what Jim already knows.
If this is a school assignment, I doubt that reversed() is allowed, nor
reverse slices, since that would make the problem too easy. *cough*
Jim, can you give a brief description of what things you've learned already? Do you already know about loops?
