New submission from Brecht Machiels: set's add() method would be a little bit more useful if it would return True if the added value was already present in the set, and False if it wasn't (or the other way around). Similarly, discard() could report whether the discarded value was present in the set or not.
I suppose this could cost a couple of extra cycles and I'm not sure this is acceptable. For discard() there's always remove() that offers similar behavior. add() does not have an alternative that offers check-and-add behavior. ---------- components: Library (Lib) messages: 231226 nosy: brechtm priority: normal severity: normal status: open title: Make set's add and discard methods return useful information type: enhancement versions: Python 3.5, Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22879> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
