mike bayer <mike...@zzzcomputing.com> added the comment: where is it defined that sets are not "supposed" to contain mutable items? such a requirement vastly limits the usefulness of sets.
Consider that relational database rows are mutable. A result set containing multiple rows which each have a primary key comprises a set, hashed on primary key. But other attributes of each row can be updated. Surely this is not controversial ? What Python data structure should I (and a whole bunch of Python ORMs) be using to represent mutable, relational database rows, unordered and unique on primary key, in memory ? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9269> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
