Assuming that both list are of the same length, then, I find the following more elegant: list1=[1,2,3] list2=[4,5,6] reduce(lambda x, y: x+y, zip(list1, list2)) of course, zip creates tuples, so you end up with a tuple, therefore if you need for your solution to be a list: list(reduce(lambda x, y: x+y, zip(list1, list2))) of reduce(lambda x, y: x+y, list(zip(list1, list2)) ) Yves. http://www.SollerS.ca -- http://mail.python.org/mailman/listinfo/python-list
