New submission from Tom Clarke <t.cla...@ic.ac.uk>: The enclosed script when run under 2.6.2 IDLE standard distribution on x86 shows that shallow copy (.copy()) of a non-empty defaultdict object returns an empty defaultdict!
Other ways to copy, e.g. defaultdict(none, d.items()), work fine. Bug appears under: Python 2.6.2 (r262:71605, Apr 14 2009, 22:40:02) [MSC v.1500 32 bit (Intel)] on win32 I have tested it on two different computers. They both also have the visual installed from a v2.6 binary - but I can't see why this would change standard libraries. Hope I am not being stupid - this seems to big a bug to be real! **Documentation on defaultdict states (nearly all) methods are same as dict, and on dict defines copy() as returning a shallow copy. **replace defaultdict by dict and this example works as expected Best wishes, Tom PS - I am new to python so forgive any stupidity! ---------- components: Library (Lib) messages: 91242 nosy: tomcl severity: normal status: open title: non-empty defaultdict .copy() fails returning empty dict type: behavior versions: Python 2.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6637> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
