New submission from Lev Givon: Not sure if this is indicative of a bug, but I noticed that a frozenset created from a set seems to occupy a different amount of memory than a frozenset created from some other iterable. I observed this behavior with Python 2.7.5 and with Python 3.4.0 on Ubuntu 14.04 x86_64:
>>> from sys import getsizeof >>> x = range(100) >>> s = set(x) >>> f0 = frozenset(x) >>> f1 = frozenset(s) >>> getsizeof(s) 8424 >>> getsizeof(f0) 8424 >>> getsizeof(f1) 4328 >>> f0==f1 True Original question on StackOverflow available at https://stackoverflow.com/questions/23618259/memory-occupied-by-set-vs-frozenset-in-python-2-7 ---------- messages: 218524 nosy: lebedov priority: normal severity: normal status: open title: memory used by frozenset created from set differs from that of frozenset created from other iterable type: resource usage versions: Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21507> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
