Cool use of 'zip' and extended slicing! Just thought I would add that 'zip' truncates after the shortest sequence, which would cause data loss for strings of odd length -- of course, the OP may not consider this a problem. In [1]: k = 'abcdefghi' # <- note the 'i' In [2]: len(k) Out[2]: 9 In [3]: [''.join(i) for i in zip(k[::2], k[1::2])] Out[3]: ['ab', 'cd', 'ef', 'gh'] # <- 'i' is gone HTH, Marty _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
