Since that method doesn't return anything explicitly, None is returned by default, and you are printing that. > i=i+1 One simple fix - change the summary method to returnt the values rather than print them - replace 'print' with 'return' in that method. Another would be not to print the returned values - remove 'print' from your while loop. -- Cheers, Simon B, [EMAIL PROTECTED], http://www.brunningonline.net/simon/blog/ -- http://mail.python.org/mailman/listinfo/python-list
