Raymond Hettinger <raymond.hettin...@gmail.com> added the comment: There's no need to guess what it does ;-) We don't document by experiment when source and test suites are available.
Mathew was correct, it works as documented: the key function is applied at the outset (as it always does) and then cmp function is used whenever a comparison is made (as it always does). There is no special change in behavior when the two are used together; they are effectively orthogonal (the actual implementation is a bit more complicated). IMO, the docs are correct as-is. There is some question about whether to specifically elaborate on what happens when both are used together. For the most part, users are better-off using either key-functions or cmp-functions but not both at the same time. We may be doing them a disservice by suggesting otherwise. This has been out for several years now and no one has either noticed or cared, so I recommend closing with no change. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11712> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
