[issue33478] PEP 8 CapWords reference wrong?
by Amit Saha May 13, 2018

May 13, 2018

New submission from Amit Saha <amitsaha.in(a)gmail.com>: PEP 8 suggests class names and type variable names to be in CapWords case. However: >>> import string >>> string.capwords('CapWord') 'Capword' Wondering if this this an oversight or am I misunderstanding something? ---------- assignee: docs@python components: Documentation messages: 316446 nosy: Amit.Saha, docs@python priority: normal severity: normal status: open title: PEP 8 CapWords reference wrong? _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue33478> _______________________________________

[issue16823] Python quits on running tkinter code with threads
by Terry J. Reedy May 13, 2018

May 13, 2018

Terry J. Reedy <tjreedy(a)udel.edu> added the comment: In the message above, I asked "why this code runs in 3.x but eventually fails in 2.x?". The answer is almost certainly that I used 3.5 with tk 8.6 compiled *with* thread support and 2.7 with tk 8.5 compiled without thread support. Serhiy, if you use a system supplied 8.6 with thread support for all Python versions, that would explain why these thread examples work for you with all Python versions. If non-thread tk works for you, then the code in _tkinter.c works better on Linux (where it must have been developed) than Windows. The original failure report duplicates other similar reports. My previous responses, including proposed doc change were incomplete, as I only learned about the tcl compile option a month ago. I opened #33479, with more extensive proposed tkinter doc changes, in favor of this. ---------- stage: -> resolved status: open -> closed superseder: -> Document tkinter and threads _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue16823> _______________________________________

[issue4934] tp_del and tp_version_tag undocumented
by Antoine Pitrou May 12, 2018

May 12, 2018

Antoine Pitrou <pitrou(a)free.fr> added the comment: Both tp_del and tp_version_tag are for internal use. Besides, tp_del is obsolete as I mentioned above. So I'm going to close the issue. ---------- resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue4934> _______________________________________

[issue4934] tp_del and tp_version_tag undocumented
by Antoine Pitrou May 12, 2018

May 12, 2018

Antoine Pitrou <pitrou(a)free.fr> added the comment: The reason tp_del has remained undocumented is that it's now obsolete. You should use tp_finalize instead: https://docs.python.org/3/c-api/typeobj.html#c.PyTypeObject.tp_finalize tp_finalize is roughly the C equivalent of __del__ (tp_del was something else, despite the name). ---------- versions: +Python 3.7, Python 3.8 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue4934> _______________________________________

[issue4934] tp_del and tp_version_tag undocumented
by book book May 12, 2018

May 12, 2018

book book <book78987book(a)gmail.com> added the comment: tp_del still undocumented. In my opinion, tp_del corresponds to the __del__() method of classes, because there are no other variable correspondes to it, but methods using for creating(tp_new) and initializing(tp_init) an object are not. Although __del__ method have some issue according to the offical document, but it is exist, so there must have a pointer to the function corresponding to it. ---------- nosy: +book book versions: +Python 3.6 -Python 2.6, Python 2.7, Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue4934> _______________________________________

itertools.product - missing documentation of usage of *
by Madsen, Bjorn May 11, 2018

May 11, 2018

Itertools.product has a "magic" function that isn't documented: The usage of * as precedent to a list of lists of variable length. Example: >>> from itertools import product >>> list(product(*[[-1,1], [-2,-2.5,2], [-3,3]])) [(-1, -2, -3), (-1, -2, 3), (-1, -2.5, -3), (-1, -2.5, 3), (-1, 2, -3), (-1, 2, 3), (1, -2, -3), (1, -2, 3), (1, -2.5, -3), (1, -2.5, 3), (1, 2, -3), (1, 2, 3)] The function works perfectly. The documentation of the usage is missing. Please add it.

[issue33449] Documentation for email.charset confusing about the location of constants
by Francois Labelle May 10, 2018

May 10, 2018

New submission from Francois Labelle <quantum.omega(a)gmail.com>: When mentioning the constants contained in the module email.charset, the documentation prefixes them with "Charset", for example: Charset.QP, Charset.BASE64, Charset.SHORTEST. This suggests that the constants can be found on the class "Charset" (uppercase first letter) in the module, while they are in fact contained in the the "charset" (lowercase first letter) module itself. This is probably a left-over from when the module was called email.Charset (in 2.2 I believe). Under Python 2.7, while the documentation uses the same nomenclature, at least the module is also importable under the name email.Charset so it makes more sense. ---------- assignee: docs@python components: Documentation messages: 316327 nosy: Francois Labelle, docs@python priority: normal severity: normal status: open title: Documentation for email.charset confusing about the location of constants type: enhancement versions: Python 2.7, Python 3.4, Python 3.5, Python 3.6, Python 3.7, Python 3.8 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue33449> _______________________________________

May 10, 2018

Mark Dickinson <dickinsm(a)gmail.com> added the comment: Marking as pending; we can't take this forward without more input from the OP. As far as I can tell, the documentation is perfectly correct here: I suspect that there was a misunderstanding somewhere along the line. ---------- assignee: -> docs@python components: +Documentation nosy: +docs@python resolution: -> not a bug status: open -> pending type: resource usage -> _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue33448> _______________________________________
