I think what the Original Poster actually meant was he wanted to avoid *writing out an explicit loop*. That is, he wants a one-liner, so he doesn't have to think about the details of iterating over the list. When we write: a = sum(a_sequence) aren't we doing the same thing really? -- Steven -- http://mail.python.org/mailman/listinfo/python-list
