[Tutor] Beginner Question

[Josh F]

re. Beginner Question

I'm still in the fairly early stages of learning Python, but I have an 
intermediate level of HTML, CSS, and VB6 knowledge along with the 
fundamentals of C and C++ and a very little bit of PERL..

But enough about me...Here's the solution.

message = raw_input("Enter your message:")
print message[-1::-1]

Slicing a string takes three arguments, all of which are optional: The first 
character to be sliced, the last character to be sliced, and tio slice every 
nth character.

In Python strings, -1 refers to the last character in the string and thus 
becomes the first argument.

You don't specify the second argument because you're printing the string 
from end to beginning.

Finallly, the -1 in the 3rd argument indicates that you want the string to 
be printed in reverse order (i.e. iterate backwards by one character).
