[issue47031] math.nan should note that NANs do not compare equal to anything
by Steven D'Aprano 02 Apr '22

02 Apr '22

New submission from Steven D'Aprano <steve+python(a)pearwood.info>: The IEEE-754 requirement that NANs are never equal to anything, even to themselves, is a common stumbling block for those new to the consequences of IEEE-754. See for example #47020. The documentation for math.nan would be a good place to add a note like "Due to the requirements of the `IEEE-754 standard <https://en.wikipedia.org/wiki/IEEE_754>`_, math.nan and float('nan') are never equal to any other value, including themselves. Use math.isnan to test for NANs." https://docs.python.org/3.8/library/math.html#math.nan ---------- assignee: docs@python components: Documentation keywords: easy messages: 415302 nosy: docs@python, steven.daprano priority: normal severity: normal status: open title: math.nan should note that NANs do not compare equal to anything type: enhancement versions: Python 3.10, Python 3.11, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue47031> _______________________________________

[issue46033] Duplicated sentence in for statement documentation
by Michał D 02 Apr '22

02 Apr '22

New submission from Michał D <michcio1234(a)gmail.com>: In for statement description, there seem to be two sentences meant to mean the same: > The suite is then executed once for each item provided by the iterator, in the order returned by the iterator. Each item in turn is assigned to the target list using the standard rules for assignments (see Assignment statements), and then the suite is executed. (from https://docs.python.org/3/reference/compound_stmts.html#the-for-statement) I believe only one of these sentences should be kept (probably the second one). If I am wrong, and the current version is actually correct, then it is unclear - to me it sounds like the iterator is iterated through twice, and suite is executed twice for each item. ---------- assignee: docs@python components: Documentation messages: 408189 nosy: docs@python, michcio1234 priority: normal severity: normal status: open title: Duplicated sentence in for statement documentation versions: Python 3.10 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue46033> _______________________________________

Terry J. Reedy <tjreedy(a)udel.edu> added the comment: I am writing a PR with an internal link. I decided that linking to Standard Encodings is sufficient. The Python Text Encodings section follows that. Anyone wanting to use any of those can experiment to see which work. ---------- _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue24563> _______________________________________
