[issue34083] Functional Programming HOWTO: Dictionary ordering isn't "essentially random"
New submission from Stig Johan Berggren <stigjb@gmail.com>: The section about iterators in the Functional Programming HOWTO (https://docs.python.org/3/howto/functional.html#data-types-that-support-iter...) states the following about looping over dictionary keys: "Note that the order is essentially random, because it’s based on the hash ordering of the objects in the dictionary." Starting with 3.7, dictionary order is guaranteed to be the same as insertion order. ---------- assignee: docs@python components: Documentation messages: 321375 nosy: Stig Johan Berggren, docs@python priority: normal severity: normal status: open title: Functional Programming HOWTO: Dictionary ordering isn't "essentially random" versions: Python 3.7 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue34083> _______________________________________
