Best way to loop over a python string backwards

Question

What is the best way to loop over a python string backwards?

The following seems a little awkward for all the need of -1 offset:

string = \"trick or          


        

Answer 1

 string = "trick or treat"
 for c in string[::-1]:
     print c

I would use that. It is probably quite fast although there may be a slightly better way (but I doubt it).

EDIT: Actually, with a second test using a program I hacked together, reversed is probably the way to go.
