[issue11230] "Full unicode import system" not in 3.2
by John July 19, 2017

July 19, 2017

New submission from John <jh45dev(a)gmail.com>: A few months ago I read that in 3.2 it will be possible to import modules that are located on paths containing any unicode character. (more precisely, with chars not in the local code page) After an hour or two trying to get this to work in 3.2rc3, I went looking for clues, and found these 2 messages in which Victor Stinner says this feature is delayed until Python 3.3: http://bugs.python.org/issue3080#msg126514 http://bugs.python.org/issue10828#msg125787 Could you please make it clear in documentation and web pages, that this feature is not working yet. The Python 3.2 download page includes this: "countless fixes regarding bytes/string issues; among them full support for a bytes environment (filenames, environment variables)" and I guessed this must cover importing from any unicode path, as there was no mention that such importing had been abandoned for this version. -- jh ---------- assignee: docs@python components: Documentation messages: 128711 nosy: docs@python, jh45 priority: normal severity: normal status: open title: "Full unicode import system" not in 3.2 versions: Python 3.2 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11230> _______________________________________

[issue15360] Behavior of assigning to __dict__ is not documented
by Davide Rizzo July 13, 2017

July 13, 2017

New submission from Davide Rizzo <sorcio(a)gmail.com>: The documentation (at least the obvious places, see Doc/reference/datamodel.rst) says classes and class instances have the '__dict__' attribute, but nothing is said about what happens when assigning to it (like obj.__dict__ = something). As far as I understand that's undefined behavior and other implementations may not work the same as CPython (and CPython itself behaves differently between versions). I'd submit a documentation patch if I knew how to specify this matter. Maybe just say the behavior is not defined? ---------- assignee: docs@python components: Documentation, Interpreter Core messages: 165538 nosy: davide.rizzo, docs@python priority: normal severity: normal status: open title: Behavior of assigning to __dict__ is not documented versions: Python 2.7, Python 3.3, Python 3.4 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue15360> _______________________________________

[issue10438] list an example for calling static methods from WITHIN classes
by Ian July 12, 2017

July 12, 2017

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> _______________________________________

[issue11681] -b option undocumented

New submission from Éric Araujo <merwok(a)netwok.org>: Python 2 has a -b command-line option which is undocumented. It is used by the warnings machinery to decide to warn about (-b) or raise an error (-bb) if someone uses str(bytes) or str(buffer) (explanation courtesy of grep and Python/pythonrun.c). ---------- assignee: docs@python components: Documentation keywords: easy messages: 132195 nosy: docs@python, eric.araujo priority: normal severity: normal stage: needs patch status: open title: -b option undocumented versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11681> _______________________________________

[issue15346] Tkinter dnd has no documentation
by Daniel Swanson April 30, 2017

April 30, 2017

New submission from Daniel Swanson <popcorn.tomato.dude(a)gmail.com>: The title should be self explanatory. I needed Drag-and-drop for a project I was working on, (maybe I shouldn't be refering to it in the past tense as I haven't started yet) so I checked the documentation for tkinter and found: 3.3.0 b1 tkinter.dnd Drag-and-drop support for tkinter. This is experimental and should become deprecated when it is replaced with the Tk DND. 3.2.2 (and .2.3) tkinter.dnd Drag-and-drop support for tkinter. This is experimental and should become deprecated when it is replaced with the Tk DND. 2.7.3 Tkdnd Drag-and-drop support for Tkinter. This is experimental and should become deprecated when it is replaced with the Tk DND. I think that tkinter.dnd needs some documentation, whether or not it is replaced with Tk DND. ---------- assignee: docs@python components: Documentation messages: 165392 nosy: docs@python, weirdink13 priority: normal severity: normal status: open title: Tkinter dnd has no documentation versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue15346> _______________________________________

[issue15369] pybench and test.pystone poorly documented
by Florent Xicluna March 31, 2017

March 31, 2017

New submission from Florent Xicluna <florent.xicluna(a)gmail.com>: The benchmarking tools "pystones" and "pybench" which are shipped with the Python standard distribution are not documented. The only information is in the what's-new for Python 2.5: http://docs.python.org/dev/whatsnew/2.5.html?highlight=pybench#new-improved… IMHO, they should be mentioned somewhere in the HOWTOs, the FAQ or the standard library documentation ("Development Tools" or "Debugging and Profiling") ---------- assignee: docs@python components: Benchmarks, Documentation messages: 165603 nosy: docs@python, flox priority: normal severity: normal status: open title: pybench and test.pystone poorly documented type: behavior versions: Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue15369> _______________________________________

[issue16011] "in" should be consistent with return value of __contains__
by Neal Parikh March 29, 2017

March 29, 2017

New submission from Neal Parikh: The Python 2.7.3 documentation says the following about defining __contains__: "Called to implement membership test operators. Should return true if item is in self, false otherwise. For mapping objects, this should consider the keys of the mapping rather than the values or the key-item pairs." This suggests that while you should return True/False, you don't need to. Also, the documentation doesn't say that if you return a value other than True or False, it will silently coerce other values to be True or False when you use "in". For example: >>> class Foo(object): ... def __contains__(self, item): return 42 ... >>> foo = Foo() >>> 3 in foo True >>> foo.__contains__(3) 42 When __contains__ is defined, "in" should return whatever __contains__ returns, even if this value is neither True nor False. That would be consistent with, for example, the comparison operators: You can return anything from __lt__ and "x < 4" will correctly pass along that value regardless of what it is. ---------- assignee: docs@python components: Documentation, Interpreter Core messages: 171085 nosy: docs@python, nparikh priority: normal severity: normal status: open title: "in" should be consistent with return value of __contains__ type: behavior versions: Python 2.7 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue16011> _______________________________________

[issue15657] Error in Python 3 docs for PyMethodDef
by Sandro Tosi Feb. 22, 2017

Feb. 22, 2017

New submission from Sandro Tosi: Hello, it has been reported at http://mail.python.org/pipermail/docs/2012-April/008215.html but given it raises some question whether it's a bug in the doc or in the code, i'd rather report the issue here and hear what other think: >>> In the Python 3.2.2 documentation (and earlier Python 3 versions), in the Python/C API Reference Manual, chapter Object Implementation Support, the documentation for PyMethodDef says: The ml_flags field is a bitfield which can include the following flags. The individual flags indicate either a calling convention or a binding convention. Of the calling convention flags, only METH_VARARGS and METH_KEYWORDS can be combined (but note that METH_KEYWORDS alone is equivalent to METH_VARARGS | METH_KEYWORDS). The bit in the parenthetical is incorrect. If you take a look at PyCFunction_Call in Objects/methodobject.c, you will find a switch for METH_VARARGS | METH_KEYWORDS, but no switch for METH_KEYWORDS. Hence, using METH_KEYWORDS will land you with a SystemError that complains about METH_OLDARGS. This is either a bug in the documentation, or a bug in Python. In this case, since the code has persisted through three major revisions of Python 3, I suggest that the bug _is_ in the documentation (whether it should be or not), since changing the code for this at this late date means a programmer has to use METH_VARARGS | METH_KEYWORDS anyway for compatibility. It may be work pointing out specifically in the documentation that just using METH_KEYWORDS will not work. <<< ---------- assignee: docs@python components: Documentation messages: 168226 nosy: docs@python, sandro.tosi priority: normal severity: normal stage: patch review status: open title: Error in Python 3 docs for PyMethodDef versions: Python 3.2, Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue15657> _______________________________________
