New submission from arjun v <arjun...@gmail.com>: In python 3.6 (and above hopefully), dictionary keys are going to be ordered, while their documentation still reference them as being unordered.
https://docs.python.org/3/tutorial/datastructures.html#dictionaries 1: `It is best to think of a dictionary as an unordered set of key: value pairs,...` 2: `Performing list(d.keys()) on a dictionary returns a list of all the keys used in the dictionary, in arbitrary order..` The examples should also be changed to reflect the same: ``` >>> tel = {'jack': 4098, 'sape': 4139} >>> tel['guido'] = 4127 >>> tel {'sape': 4139, 'guido': 4127, 'jack': 4098} >>> tel['jack'] 4098 >>> del tel['sape'] >>> tel['irv'] = 4127 >>> tel {'guido': 4127, 'irv': 4127, 'jack': 4098} >>> list(tel.keys()) ['irv', 'guido', 'jack'] >>> sorted(tel.keys()) ['guido', 'irv', 'jack'] >>> 'guido' in tel True >>> 'jack' not in tel False ``` ``` >>> dict([('sape', 4139), ('guido', 4127), ('jack', 4098)]) {'sape': 4139, 'guido': 4127, 'jack': 4098} ``` ``` >>> dict(sape=4139, guido=4127, jack=4098) {'sape': 4139, 'guido': 4127, 'jack': 4098} ``` ---------- assignee: docs@python components: Documentation messages: 314892 nosy: arjunv, docs@python priority: normal severity: normal status: open title: Fix instances in documentation where dictionaries are referenced as unordered versions: Python 3.6, Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33218> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
