[issue9305] Don't use east/west of UTC in date/time documentation
by Alexander Belopolsky 14 Feb '20

14 Feb '20

New submission from Alexander Belopolsky <belopolsky(a)users.sourceforge.net>: I am opening this to supersede issue7229. See discussion following msg107148. In many places offsets representing the difference between local time and UTC are described as minutes or seconds east or west of UTC. This is not correct because UTC is not a place and minutes and seconds don't measure distance in this context. Replacing UTC with the Prime Meridian will not fix that because some regions in the western hemisphere use positive offsets from UTC. or example, Madrid is at 3° 42' West, but uses Central European Time which is UTC+1. I believe geographical references in the python documentation are irrelevant. What users are interested in is how to convert local time to UTC and UTC to local time rather than what is the sign of time.timezone in Madrid. I suggest the following wording for time.timezone description: time.timezone: The number of seconds one must add to the local time to arrive at UTC. Similarly, tzinfo.utcoffset() can be defined as "Returns timedelta one must add to UTC to arrive at local time." ---------- assignee: docs@python components: Documentation keywords: easy messages: 110774 nosy: belopolsky, docs@python priority: normal severity: normal stage: needs patch status: open title: Don't use east/west of UTC in date/time documentation type: feature request versions: Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue9305> _______________________________________

[issue9938] Documentation for argparse interactive use
by Jay T 12 Sep '19

12 Sep '19

New submission from Jay T <jaytula(a)gmail.com>: I want to create a custom interactive shell where I continually do parse_args. Like the following: parser = argparse.ArgumentParser() command = raw_input() while(True): args = parser.parse_args(shlex.split(command)) # Do some magic stuff command = raw_input() The problem is that if I give it invalid input, it errors and exits with a help message. I learned from argparse-users group that you can override the exit method like the following: class MyParser(ArgumentParser): def exit(self, status=0, message=None): # do whatever you want here I would be nice to have this usage documented perhaps along with best practices for doing help messages in this scenario. ---------- assignee: docs@python components: Documentation messages: 117287 nosy: docs@python, jayt priority: normal severity: normal status: open title: Documentation for argparse interactive use type: feature request versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue9938> _______________________________________

[issue10536] Enhancements to gettext docs
by Éric Araujo 09 May '19

09 May '19

New submission from Éric Araujo <merwok(a)netwok.org>: A patch made for #2504 revealed a bug in gettext.rst, and I’ve found a number of other things to change in the file. This is the first patch of a series of two or three. Barry, as the original author of the module and doc, I’d like your opinion on points 3, a, and b particularly. Patch is also uploaded to Rietveld for greater convenience: http://codereview.appspot.com/3333042/ (upload.py rocks) Summary: 1) Markup: Use modern class/method directives combo (yay DRY). Mark up variable parts in :file: constructs (e.g. :file:`{domain}.mo` will cause the HTML output to use var to indicate replaceable text). Also change some ``gettext`` to :program:`gettext` for consistency. 2) Fix a typo in lngettext doc (originally included in patch by Franz Glasner for #2504). 3) I had started to remove information about private attributes (_info, _charset), advertising public getter methods instead. Then I read the description of NullTranslations and realized the information was needed for subclasses. I’ve reverted my removals, but I still think the private attributes should be listed in a specific section for people writing subclasses and not in the rest of the text. If you’re okay, I’ll make a second patch. 4) Assorted wording changes, missing periods and hyphens, and other very small touch-ups: Turned a broken bare link into a working link with nice text; used the with statement in an example (we all love the with statement!); used two spaces after periods throughout (hello Fred Drake). Final note: lines have not been rewrapped, for diff clarity. When I commit part or all of this patch, I’ll make another commit to rewrap. Not addressed: a) The current docs is currently POSIX-specific. b) The docs take great care to explain that Unicode strings will be returned in different places, but this should not be so accented in 3.x docs IMO. I would just put a note somewhere near the top that all strings are str and remove the redundant sentences. Following that line of thought, I could group all l*gettext variants at the end of the list of methods, explaining that regular usage should just be happy with str objects and that l*gettext are available if people really want bytes. c) The file uses “built-in namespace” and “builtins namespace”, sometimes in neighbor paragraphs. :mod:`builtins` is not used, even in explanations of the install function/method. I don’t know if I should change that. d) Some capitalization patterns look strange to me: I have seen “I18N” and “L10N” in upper case nowhere else. Similarly, lower-case “id” looks stranger than “ID”. The latter is used for example in official GNU gettext docs. Am I going into foolish consistency territory or not? Thanks in advance for reviews and opinions. ---------- assignee: eric.araujo components: Documentation files: gettext-docs-1.diff keywords: needs review, patch messages: 122420 nosy: barry, docs@python, eric.araujo priority: normal severity: normal stage: patch review status: open title: Enhancements to gettext docs versions: Python 2.7, Python 3.1, Python 3.2 Added file: http://bugs.python.org/file19819/gettext-docs-1.diff _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue10536> _______________________________________

[issue10048] urllib.request documentation confusing
by Antoine Pitrou 26 Apr '19

26 Apr '19

New submission from Antoine Pitrou <pitrou(a)free.fr>: The urllib.request documentation intermingles old 2.x urllib (FancyURLopener, etc.) with urllib2-inherited (*Handler, build_opener, etc.) primitives without making any distinction. This makes it rather confusing for the reader to figure out which ones to use. Ideally, the use of the old primitives should also be discouraged. ---------- assignee: docs@python components: Documentation messages: 118179 nosy: docs@python, orsenthil, pitrou priority: normal severity: normal stage: needs patch status: open title: urllib.request documentation confusing versions: Python 3.1, Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue10048> _______________________________________

New submission from Éric Araujo <merwok(a)netwok.org>: Built-in containers like dict use an ellipsis to represent a recursive item.

[issue8722] Documentation for __getattr__
by Paul Davis 04 Feb '18

04 Feb '18

New submission from Paul Davis <paul.joseph.davis(a)gmail.com>: The docs for __getattr__ in the object model section could be more specific on the behavior when a @property raises an AttributeError and there is a custom __getattr__ defined. Specifically, it wasn't exactly clear that __getattr__ would be invoked after a @property was found and evaluated. The attached script demonstrates the issue on OS X 10.6, Python 2.6.1 I'm thinking something along the lines of: If the attribute search encounters an AttributeError (perhaps due to a @property raising the error) the search is considered a failure and __getattr__ is invoked. ---------- assignee: docs@python components: Documentation files: example.py messages: 105790 nosy: Paul.Davis, docs@python priority: normal severity: normal status: open title: Documentation for __getattr__ type: feature request versions: Python 2.6 Added file: http://bugs.python.org/file17349/example.py _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue8722> _______________________________________

[issue10438] list an example for calling static methods from WITHIN classes
by Ian 12 Jul '17

12 Jul '17

New submission from Ian <ifreecarve(a)gmail.com>: Concerning this section of the docs: http://docs.python.org/library/functions.html#staticmethod There is no example for calling a static method from another static method within the same class. As I discovered later, it's simple: C.f() -- from inside the class or outside it. A total newbie will accept this and move on... but in other programming languages, it's frowned upon to the class name from within the class. For example, in PHP you use the "self::" prefix and Java you don't need a prefix at all. So, even though I had it right the first time, it didn't SEEM right... so I went on a wild goose chase, for nothing. Googling "java call static method" will get you java documentation that lists both cases, as does "c++ call static method" and "php call static method". I feel that by adding "Note: you must also use the C.f() syntax when calling from within the class", the documentation will be more complete. ---------- assignee: docs@python components: Documentation messages: 121314 nosy: docs@python, ifreecarve priority: normal severity: normal status: open title: list an example for calling static methods from WITHIN classes type: feature request _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue10438> _______________________________________

[issue10415] readline.insert_text documentation incomplete
by Justin Lebar 30 Sep '16

30 Sep '16

New submission from Justin Lebar <justin.lebar(a)gmail.com>: The readline documentation currently says: > readline.insert_text(string) > Insert text into the command line. But as far as I can tell, readline.insert_text() does something only when called from startup_hook or pre_input_hook.

New submission from DSM <dsm001(a)users.sourceforge.net>: Various typo fixes for the docs. As usual, I left historical documents alone (except for 3.1 whatsnew: fixed the spelling of Jack Diederich's name). Fixing ~30 means I probably introduced ~3 problems of my own, but that should still be a net win..

[issue9014] Incorrect documentation of the PyObject_HEAD macro
by Renato Cunha 19 Apr '16

19 Apr '16

New submission from Renato Cunha <renato(a)renatocunha.com>: PyObject_HEAD's documentation in py3k (http://docs.python.org/dev/py3k/c-api/structures.html#PyObject_HEAD) uses the same content used in the python 2.x's docs which is wrong, as there were some API changes. PyObject_HEAD is actually defined as #define PyObject_HEAD PyObject ob_base; with PyObject defined as typedef struct _object { _PyObject_HEAD_EXTRA Py_ssize_t ob_refcnt; struct _typeobject *ob_type; } PyObject; (The PyTRACE_REFS discussion is still valid, though.) Additionally, it'd be nice to mention that the Py_REFCNT(ob) and Py_TYPE(ob) macros should be used to access the PyObject members. ---------- assignee: docs@python components: Documentation messages: 107953 nosy: docs@python, trovao priority: normal severity: normal status: open title: Incorrect documentation of the PyObject_HEAD macro type: behavior versions: Python 3.1, Python 3.2, Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue9014> _______________________________________
