Ezio Melotti added the comment: Raymond, since this has been merged to default too in e163c13b941c, can the issue be closed or is there something else left to do? -- nosy: +ezio.melotti ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17920 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17920] Documentation: complete ordering should be total ordering
New submission from abcdef: The set documentation [http://docs.python.org/3.4/library/stdtypes.html] states The subset and equality comparisons do not generalize to a complete ordering function. For example, any two disjoint sets are not equal and are not subsets of each other... Could complete ordering be changed to total ordering? This is the correct mathematical terminology. A total ordering is one where every pair is comparable. A complete ordering is one where each bounded subset has a supremum/infimum (for example, reals form a complete ordered field). This can be verified at Wikipedia [http://en.wikipedia.org/wiki/Total_order] and essentially every set theory book. -- assignee: docs@python components: Documentation messages: 188585 nosy: abcdef, docs@python priority: normal severity: normal status: open title: Documentation: complete ordering should be total ordering type: enhancement versions: Python 2.7, Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17920 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

abcdef added the comment: Another small thing: For example, any two disjoint sets are not equal and are not subsets of each other, so all of the following return False: ab, a==b, or ab. It should be any two nonempty disjoint sets. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17920 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
