Serhiy Storchaka added the comment: IP address instances already are immutable and flyweight. There are no mutating methods. And a number of address attributes (packed, is_loopback, etc) are calculated on fly from integer representation.
But IP address objects can be lighter. 1) Use __slots__. 2) Every instance has the _version attribute. Why this is not class attribute? 3) Memory consumption can be even less if IP addresses would int subclasses. But this changes the API (in particular adds the __index__ method) and I doubt that we should do this. ---------- nosy: +serhiy.storchaka _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23103> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
