I have a list (or a list-like object, doesn't matter) of objects, each of which has multiple fields. I want to be able to arbitrarily sort the list on any of them, or at least on several of them.
To make this a little more concrete, here's a simplified idea. Say the objects each represent a file, and I've got fields in it like this: self.filesz: size of the file self.filename: name of the file self.users : a list of people who need to know if the file gets updated self.filetype : a short description of the file contents etc. I sometimes want to sort the list by filesz; and sometimes by filename; and maybe sometimes by some other field. My sense right now is that the "list" of these objects itself should be an object inheriting from list, and that I should create a small sort method for each field I intend to sort on. (I don't have the book handy, but there's a nice recipe for this in the Python Cookbook, 2d Edition, for such a method.) Is there a better (more clear and easy) way to be able to do this, or am I pretty much on the right track? _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
