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

reversed takes an iterable and and returns an iterator that moves backwards. string[::-1] is fine, but it creates a new, reversed string instead. If you just want to iterate, then this will probably better:

for c in reversed(string):
    print c

If you want to use the reversed string afterwards, creating it once will be better.
