[issue40971] Documentation still mentions 'u' string formatting option
New submission from Gordon P. Hemsley : https://docs.python.org/3/library/stdtypes.html#old-string-formatting still lists the 'u' string formatting option, described as "Obsolete type – it is identical to 'd'." and linking to PEP 237. However, testing indicates that Python 3 does not support a 'u' option and my archaeology suggests that such support was removed in Python 2.4. It seems this has flown under the radar for quite some time. -- assignee: docs@python components: Documentation messages: 371474 nosy: alexandre.vassalotti, benjamin.peterson, berker.peksag, christian.heimes, docs@python, eli.bendersky, ezio.melotti, georg.brandl, gphemsley, martin.panter, ncoghlan, rhettinger priority: normal severity: normal status: open title: Documentation still mentions 'u' string formatting option type: behavior versions: Python 3.10, Python 3.5, Python 3.6, Python 3.7, Python 3.8, Python 3.9 ___ Python tracker <https://bugs.python.org/issue40971> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue36967] Eliminate unnecessary check in _strptime when determining AM/PM
New submission from Gordon P. Hemsley : Since __calc_am_pm() explicitly limits self.am_pm to 2 values, there are only ever 3 possible values of %p: AM, PM, or blank. Since blank is treated the same as AM, there is only the need to check whether %p is PM. This eliminates an unnecessary comparison and doubly ensures that there is no unhandled case. -- messages: 342872 nosy: gphemsley, p-ganssle priority: normal severity: normal status: open title: Eliminate unnecessary check in _strptime when determining AM/PM versions: Python 3.8 ___ Python tracker <https://bugs.python.org/issue36967> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue36959] ISO date errors in _strptime are jumbled
Gordon P. Hemsley added the comment: Ah yes, to be clear, I wasn't trying to suggest that the error messages themselves were wrong—just that they weren't triggering when the tests were expecting them to. Some of the existing tests currently trigger the "unconverted data remains" ValueError from earlier in the method, but because the messages are not checked, that is not immediately obvious.

This is cumbersome and often impossible. Both implementation > should have the same behavior, and they do have. As it stands, calling Element.__deepcopy__() will succeed with the C implementation and fail with the Python implementation. That seems problematic to me, and making that *not* be the case is trivial, so I don't understand the generalization to "all implementation details". Additionally, if copy.deepcopy() already works well with the Python implementation, why would it not work on the C implementation? What is different about the C implementation that requires the definition of __deepcopy__() in the first place? >> And additional tests have in fact uncovered further discrepancies between >> the Python and C implementations with regard to copying behavior. > > What are these discrepancies? As I mentioned in the PR, the C implementation does not make use of Element.__init__() when it creates new instances of the class, opting instead to use create_new_element() (which is not used in the C implementation of Element.__init__()). However, create_new_element() does not make a copy of the attrib dict that is passed in, meaning that the internal attrib dict of an Element instance is mutable by changing the dict that was passed in. I have modified the C implementation to fix this problem by adding a copy line in create_new_element(). Without this change, some of the new tests in the PR will fail in the C implementation. The Python implementation does not have this problem because it inherently always goes through Element.__init__(). > In any case it is better to extend existing tests by adding missed checks > than duplicate tests. As I mentioned in the PR: I have added the unit tests in the way that I have because the existing checks are generally integration tests, and most of the test coverage for this module comes as a side effect of pickle tests. It is my goal to expand the unit tests later to test each method individually, so starting that work here makes it easier. -- ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32424> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue32466] Remove fractions._gcd()
Gordon P. Hemsley <gphems...@gphemsley.org> added the comment: Indeed, that is the code fragment I was referring to. Mathematically speaking, a rational number is one that can be expressed as a fraction of two integers, so in that regard the numerator and the denominator should both be integers. But let's assume for argument's sake that a type comes through where the numerator and the denominator are fractions: 1/2 and 2/3, respectively. This code would normalize them by cross-multiplying: numerator = 1 * 3 = 3 denominator = 2 * 3 = 6 Now they are both integers. In what scenario would the numerator and denominator be numbers.Rational but not an integer or a fraction? If someone could even come up with one, would it be worthwhile to allow as a fraction? And on the flip side, if math.gcd() only accepts integers and not, at least, numbers.Integral, wouldn't that be a bug? -- ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32466> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from Gordon P.

I initially was going to implement a test for that line, but upon further reflection, I cannot envision a scenario where that would be possible. The code already requires its initial parameters to be numbers.Rational and then normalizes their numerators and denominators to be integers. So, instead, I propose to remove this check, first introduced in issue22486, and to roll the fractions._gcd() function up into the deprecated fractions.gcd(). -- components: Library (Lib), Tests messages: 309288 nosy: gphemsley, mark.dickinson, rhettinger priority: normal severity: normal status: open title: Remove fractions._gcd() versions: Python 3.7 ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32466> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from Gordon P.

This has two drawbacks: * If the built-in XMLParser is specified explicitly, it does not get the advantage of using its _parse_whole() method. * If another XML parser is specified, it does not have the option to define a _parse_whole() method. In both cases, the parser parses in chunks (of 16 KiB), which is potentially slower. I propose allowing any parser to take advantage of _parse_whole() if it has defined such a method.

Given that the documentation makes no mention of a copy() method and that its definition would be masked by a standard import of xml.etree.ElementTree, I propose that it be renamed to __copy__() so that copy.copy() can make use of it. -- components: Library (Lib), XML messages: 309010 nosy: eli.bendersky, gphemsley, scoder priority: normal severity: normal status: open title: Rename copy() to __copy__() in xml.etree.ElementTree.Element Python implementation type: behavior versions: Python 3.7 ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32424> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue28236] In xml.etree.ElementTree Element can be created with empty and None tag
Gordon P. Hemsley <gphems...@gphemsley.org> added the comment: To be clear, we are talking about the Element class of the ElementTree module, which is distinct from the ElementTree class of the same module. That said, I personally question the implementation decision to represent things like treating comments as an Element with a tag of a Comment function. The XML standard is pretty clear that neither comments nor processing instructions are in fact elements, and I don't see it as a Good Thing that arbitrary objects are allowed as the value of tag, unless there is a requirement that such objects are subclasses of str. Note also that the documentation makes no mention of tag being anything other than a string. And there is inconsistency with where bytes are supposedly allowed (according to the documentation) and where they're actually allowed (according to the code). Given this, I think it's hard to say what user code is expected to make use of. -- ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue28236> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue28236] In xml.etree.ElementTree Element can be created with empty and None tag
Gordon P. Hemsley <gphems...@gphemsley.org> added the comment: I disagree. This library is meant to be an interface onto XML syntax, and XML has pretty strict requirements on syntax. As msg277125 shows, you're liable to get very far downstream before the error becomes apparent. In addition, I'm finding a number of internal inconsistencies, both between the docs and the code and between the Python code and the C code, that demonstrate that doing these type checks up front would be beneficial to the entire library. (Note: The C code also does not do them.) -- ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue28236> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Gordon P. Hemsley <gphems...@gphemsley.org> added the comment: I decided to take a look at this, since it seems easy... At first glance, this would appear to be a straightforward change--the docs state in multiple places that Element() takes a string as its tag argument. But it turns out that a lot of internal functionality depends on passing in non-strings as the tag value. -- nosy: +gphemsley ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue28236> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
