In addition to what others have said, you can use the map builtin as follows: In Python 2.x: >>> map(int.__mul__, [2, 4, 3, 1], [5, 9, 10, 6]) [10, 36, 30, 6] If you don't know the list only contain ints use operator.mul. In Python 3.x you need to wrap it in list() as map returns an iterator. HTH -- Arnaud -- http://mail.python.org/mailman/listinfo/python-list
