Petr Viktorin added the comment: The array module is good if you *really* drop references:
$ ./python -X showrefcount Python 3.5.0a4+ (default, May 23 2015, 16:44:38) [GCC 4.9.2 20150212 (Red Hat 4.9.2-6)] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import sys, gc [54618 refs, 15960 blocks] >>> import array; del array; del sys.modules['array']; gc.collect() 6 [54851 refs, 15973 blocks] >>> import array; del array; del sys.modules['array']; gc.collect() 6 [54851 refs, 15973 blocks] >>> import array; del array; del sys.modules['array']; gc.collect() 6 [54851 refs, 15973 blocks] There is a cycle between a each built-in function and its module. Modules aren't optimized for being unloaded. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24268> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
