Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Documentation Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Calvin Spealman (ironfroggy) Assigned to: Nobody/Anonymous (nobody) Summary: Dictionary ordering docs are too unclear of dangers Initial Comment: The footnote #3 on this page of the documentation details some thoughts on the order of dictionaries and the results of the different key and value retreival methods. I think it promises more than it should. The current content tells the reader they can expect consistant results from a dictionary as far as order goes, and we know this to be simply untrue and even in the circumstances where its likely (but still not impossible), such as `zip(d.values(), d.keys())` there is not even any compelling reason to use such odd methods, making the very fact that the idea is documented suspect. I recommend the footnote be removed entirely, or replaced with "Keys and values are listed in an arbitrary order which is non-random, varies across Python implementations, and depends on the dictionary's history of insertions and deletions. Do not expect anything of the order of the items(), keys(), values(), iteritems(), iterkeys(), and itervalues() methods' results."
