Seth Bromberger added the comment: 1) However:
>>> b = ipaddress.IPv4Address('1.2.3.4') >>> a = ipaddress.IPv4Address('1.2.3.4') >>> id(a) 4428380928 >>> id(b) 4428381768 >>> a == b True >>> b._ip += 6 >>> id(b) 4428381768 >>> b IPv4Address('1.2.3.10') 2) Isn’t _version already a class attribute? It’s set in _Basev4/Basev6. 3) Memory consumption seems particularly wasteful in the current implementation: it takes 56 bytes (via sys.getsizeof) to store what amounts to 4 bytes of data. I thought about subclassing Int as well, and I agree it’s the wrong approach. There are too many int methods that don’t make sense in the context of IP addresses. ---------- _______________________________________ 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
