I actually prefer this over every other solution to date. If you feel its too much behaviour in one line, I sometimes break it out into separate values to provide some in-code documentation: >>> s = "xxaabbddee" >>> get_two_chars_at = lambda i: s[i:i+2] >>> string_index = xrange(0, len(s), 2) >>> ':'.join(get_two_chars_at(i) for i in string_index) 'xx:aa:bb:dd:ee' -- http://mail.python.org/mailman/listinfo/python-list
