I agree the explanation is 'terse' but it does explain that the syntax is S[i:j:k] and that any/all of the values can be ommitted and what their defaults are. It also explains the significance of -1 as a value. So [::-1] is simply i, j taking defaults and -1 for k So its equivalent to S[0:len(S):-1] But I agree there could be a few more examples of the use of the k element. -- Alan Gauld Author of the Learn to Program web site http://www.freenetpages.co.uk/hp/alan.gauld _______________________________________________ Tutor maillist - [email protected] http://mail.python.org/mailman/listinfo/tutor
