Unlike copy.deepcopy() the copy() method of a dictionary does not copy objects in the dict, but seem to use them by reference. I'm not sure, if this is really a bug - but I would have expected it to behave like copy.deepcopy(), according to http://www.python.org/infogami-faq/programming/how-do-i-copy-an-object-in-python/

Logged In: YES user_id=663176 I cannot comment on infogami. It says the following is spam: """ Please note that olddict.copy() does not "deepcopy" the dictionary. So if you have a dictionary of objects, those will still be copied by reference. """ I've tried rephrasing it slightly, to no avail. Can you update the wiki page directly? Thanks.

The Infogami FAQ is no longer available from python.org, so I'll just close this item.
