[issue11023] pep 227 missing text
by Alan Isaac Jan. 26, 2018

Jan. 26, 2018

New submission from Alan Isaac <alan.isaac(a)gmail.com>: In PEP 227 missing text is marked with XXX. Most of this is just calls for examples and elaboration. However under the Implementation section XXX marks a substantive question about the documentation. Fixing this may be low priority, but a tracker search suggested it is currently not even being tracked ... ---------- assignee: docs@python components: Documentation messages: 127184 nosy: aisaac, docs@python priority: normal … [View More]

[issue11260] smtpd-as-a-script feature should be documented and should use argparse
by Xavier Morel Jan. 10, 2018

Jan. 10, 2018

New submission from Xavier Morel <xavier.morel(a)masklinn.net>: argparse has been merged to the standard library in 3.2, and (tell me if I'm wrong) would therefore be the "best-practices" way to parse command-line arguments. Numerous stdlib modules can be used as scripts, but they tend to have ad-hoc documentation (if they are at all documented) and arguments parsing (using any of the 4 available methods in Python: straight from sys.argv, getopt, optparse and argparse). I picked smtpd … [View More]

[issue11253] autodocument first appearance of ctypes.wintypes constants
by anatoly techtonik Nov. 8, 2017

Nov. 8, 2017

New submission from anatoly techtonik <techtonik(a)gmail.com>: I've just noticed that my application is incompatible with Python 2.5, because ctypes.wintypes is missing SHORT constants. However, I can't find the information when these symbols were introduced first. To prevent such confusion in future it would be nice to extract symbol information for each Python release and automatically include the version of the first appearance in documentation. ---------- assignee: docs@python … [View More]

[issue12067] Doc: remove errors about mixed-type comparisons.
by Terry J. Reedy Aug. 24, 2017

Aug. 24, 2017

New submission from Terry J. Reedy <tjreedy(a)udel.edu>: Current 3.2 doc, 5.9. Comparisons, has this paragraph about mixed-type comparisons. "The operators <, >, ==, >=, <=, and != compare the values of two objects. The objects need not have the same type. If both are numbers, they are converted to a common type. Otherwise, the == and != operators *always* consider objects of different types to be unequal, while the <, >, >= and <= operators raise a TypeError … [View More]when comparing objects of different types that do not implement these operators for the given pair of types. You can control comparison behavior of objects of non-built-in types by defining rich comparison methods like __gt__(), described in section Basic customization." Sentence 3: "If both are numbers, they are converted to a common type." I suspect it would be more true to say 'common internal type' as I would not think it a language requirement to produce Python objects. In any case, I think it is only true for built-in number types, and I do not see that qualification anywhere previously. That aside, it does not appear to be true for Decimals and Fractions in 2.7.1. Sentence 4: first clause is only true for built-in types. That qualification is not obvious to everyone, as evidenced by a current python-list sub thread. For 2.7, which has a different continuation, I suggest adding 'built-in' before 'objects of'. For 3.2/3, I suggest deleting '*always*' and adding a comma after 'TypeError' so that the 'when' condition applies to equality comparisons also. After discussion about same-type comparisons, there is another paragraph about mixed-type comparison: "Comparison of objects of the differing types depends on whether either of the types provide explicit support for the comparison. Most numeric types can be compared with one another, but comparisons of float and Decimal are not supported to avoid the inevitable confusion arising from representation issues such as float('1.1') being inexactly represented and therefore not exactly equal to Decimal('1.1') which is. When cross-type comparison is not supported, the comparison method returns NotImplemented. This can create the illusion of non-transitivity between supported cross-type comparisons and unsupported comparisons. For example, Decimal(2) == 2 and 2 == float(2) but Decimal(2) != float(2)." I suggest deleting this entirely. The first sentence and first clause of the second repeat what was said above. The rest is obsolete as float/decimal comparisons *are* implemented in 2.7.1 and 3.2.0. ---------- assignee: docs@python components: Documentation keywords: easy messages: 135873 nosy: docs@python, rhettinger, terry.reedy priority: normal severity: normal stage: needs patch status: open title: Doc: remove errors about mixed-type comparisons. versions: Python 2.7, Python 3.2, Python 3.3 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue12067> _______________________________________ [View Less]

[issue12887] Documenting all SO_* constants in socket module

New submission from Sandro Tosi <sandro.tosi(a)gmail.com>: spinning off msg142613 - it would be interesting to have in the socket module documentation also an explanation of all the several SO_ flags available; even a compact table could be ok; or even a link to a remote reference for them. ---------- assignee: docs@python components: Documentation messages: 143428 nosy: docs@python, eric.araujo, ezio.melotti, sandro.tosi priority: normal severity: normal stage: needs patch status: open … [View More]

[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/… [View More]

[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 … [View More]

[issue11681] -b option undocumented

May 13, 2017

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 … [View More]
