Sept. 12, 2019

New submission from Eric Snow <ericsnowcurrently(a)gmail.com>: The doc on code execution[1] leaves out mention of the -m flag. Seems like it belongs there too.

[issue9938] Documentation for argparse interactive use
by Jay T Sept. 12, 2019

Sept. 12, 2019

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> _______________________________________

[issue12077] Harmonizing descriptor protocol documentation
by Davide Rizzo Aug. 29, 2019

Aug. 29, 2019

New submission from Davide Rizzo <sorcio(a)gmail.com>: There are three sources of information for the descriptor protocol: - Data model reference (Doc/reference/datamodel.rst) - Descriptor HowTo guide (Doc/howto/descriptor.rst) - PEP 252 A developer who already knows descriptor tipically reads the first one: object.__get__(self, instance, owner) "... owner is always the owner class ..." Reading a bit further there are the ways a descriptor can be called, and the "direct call" is x.__get__(a). That is, without the third argument (owner) specified. The how-to definition is slightly different: descr.__get__(self, obj, type=None) --> value Here the arguments have different names ("type" shadowing the type bultin) and it seems to be implied that the third argument is optional. The ClassMethod example at the end of the document seems to confirm this: def __get__(self, obj, klass=None): (though another example doesn't). And the method contains an explicit check on klass being None. Also it could be confusing that through the examples in the same document many different names are used for the same argument (type, objtype, klass), and all different than the name used in the reference. Lastly the PEP is more explicit: __get__(): a function callable with one or two arguments. [...] When X is None, the optional second argument, T, should be meta-object. [...] When both X and T are specified ... One more quirk: the reference explains the distinction between data and non-data descriptors, though says nothing about __set__ raising AttributeError for read-only data descriptors. My proposal: - use the same names for __get__ arguments throughout the documentation (both the reference and the tutorial), e.g. __get__(self, instance, owner) - decide whether the third argument should be optional, or state the common usage in the reference, and fix accordingly the examples in the howto - explain data, non-data and read-only descriptors in the __set__ reference, or more simply, how the defintion of __set__ affects these things. ---------- assignee: docs@python components: Documentation messages: 135974 nosy: davide.rizzo, docs@python priority: normal severity: normal status: open title: Harmonizing descriptor protocol documentation versions: Python 2.7, Python 3.2, Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue12077> _______________________________________

[issue14112] tutorial intro talks of "shallow copy" concept without explanation
by Tshepang Lekhonkhobe Aug. 24, 2019

Aug. 24, 2019

New submission from Tshepang Lekhonkhobe <tshepang(a)gmail.com>: Relevant line: http://hg.python.org/cpython/file/e2eccc906354/Doc/tutorial/introduction.rs… When the concept is introduced, it appears like there's an assumption that the reader would know what it means. I'm curious if it's that common a term that it should be taken for granted, or if it deserves a definition. ---------- assignee: docs@python components: Documentation messages: 154151 nosy: docs@python, tshepang priority: normal severity: normal status: open title: tutorial intro talks of "shallow copy" concept without explanation versions: Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue14112> _______________________________________

[issue11165] Document PyEval_Call* functions
by Nick Coghlan Aug. 8, 2019

Aug. 8, 2019

New submission from Nick Coghlan <ncoghlan(a)gmail.com>: There are currently undocumented PyEval_Call* equivalents to a number of the PyObject_Call* functions. Since there are resources out there on the web that direct people to use the currently undocumented PyEval functions, it would be good to document those properly, and recommend people typically use the PyObject_Call* variants instead (as the latter include all the stack and interpreter state integrity protection code, while the PyEval variants assume that has all already been handled). ---------- assignee: docs@python components: Documentation keywords: easy messages: 128248 nosy: docs@python, ncoghlan priority: normal severity: normal stage: needs patch status: open title: Document PyEval_Call* functions versions: Python 2.7, Python 3.2, Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue11165> _______________________________________
