<snip/> The reverse() is totally useless to apply each when appending each character. Not only useless, but faulty: if you have a even number of characters, your string won't be reversed. All you need to do is this: >>> x = "abcdefg" >>> print "".join(reversed(x)) gfedcba HTH Diez -- http://mail.python.org/mailman/listinfo/python-list
