That would run into difficulties for Counters with float values: e.g., after >>> c = Counter() >>> c['spam'] = 1e100 >>> c['eggs'] = 1 >>> c['spam'] = 0 the cached total would likely be 0.0, because that's what the sum of the (new-old) values gives: >>> (1e100 - 0) + (1 - 0) + (0 - 1e100) 0.0 ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue25478> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
