You can do it as a list comprehension e.g. like this: [ x + y for x, y in zip(operandlist1, operandlist2)] Note that there is some unnecessary list building going on here and it may be better to use itertools.izip. (In python 3 zip returns an iterator anyhow.) -- http://mail.python.org/mailman/listinfo/python-list
