Actually, if you use Google code search, you'll find that multiplying the numbers in a list doesn't have much use at all. After summing numbers, joining strings is by far the most common usage -- which is much better done with the str.join() method.
(PS. I rejected the issue; product() was proposed and rejected when sum() was originally proposed and accepted, and I don't see anything to change my mind.)
