Just in case it isn't clear, that order_by actually digs into the database layer to do the sorting there. It's a query that returns an iterator that gives you stories in that order one at a time. To sort an existing list, over a particular member, it would be Stories.sort( key = lambda x: x.score ) That lambda has certainly confused a lot of people I know. Probably because they used the word "lambda" and not "function".
