I would support adding a iter_backwards() method to
strings, lists, and xrange objects.

    for i in xrange(n).iter_backwards():
            print i

    for i in range(n).iter_backwards():
            print i

    for c in "flog".iter_backwards():
            print c

It could also be implemented for other sequence objects
if there were compelling use cases and if the implementation
wasn't too hairy (file objects for instance).
