Any savings you have from optimizing this loop will be completely swamped by the network time. Why do you think this is a bottleneck? You could use [ sys.stdout.write(some operation on item) for item in data ] but I consider this bad style and I seriously doubt you will see any difference in performance. > The for loop will be called continuously and this is another reason to > look for a potentially better structure preferably a built-in. What do you mean 'called continuously'? Kent _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
