[issue5434] datetime.monthdelta
Jess Austin jess.aus...@gmail.com added the comment: Yeah, the masses have spoken, and their silence is deafening. I was going to downplay the health of the package based on the number of downloads, but then I looked at the futures page. b^) Seriously, getting this in would require a core developer wanting it in, and at this point it seems none do. On the subject of float operations, while there may be some question about the integerness or floatness of timedelta, monthdelta is definitely an integer. As monthdelta already supports multiplication by integers and floor division by integers or monthdeltas, I don't see anything missing. To use monthdeltas with floats is to miss the point entirely. -- status: pending - open ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5434 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I appreciate Alexander's more experienced perspective, but it's not obvious to me that this problem is insoluble simply due to OOP algebra. I'm going to keep tinkering with this to see if there isn't a way to satisfy his concerns AND fix these bugs WITHOUT breaking the established (and admittedly anti-OOP) behavior that dates are not equal to datetimes. (Incidentally, the test I removed still seems to be an arbitrary ad-hoc requirement that subclasses of date behave differently than date itself. I don't see how one could rely on this given the other inconsistencies with date subclasses, and so violating this in order to fix more serious problems seems acceptable.) I'm reminded of the set and frozenset situation, which seems almost dual to this one. set and frozenset don't inherit from each other, but they do compare. This seems to bite you only when you try to redefine comparison in subclasses. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5516 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue7116] str.join() should be documented as taking an iterable
New submission from Jess Austin jess.aus...@gmail.com: In its __doc__ string and in the documentation, str.join() is described as taking a sequence. This is not general enough; it actually takes any iterable of strings: ','.join(str(x) for x in range(5)) '0,1,2,3,4' Maybe this is a small nit to pick, but it slowed me down for a few minutes, and I already vaguely remembered that str.join() could handle iterables. -- assignee: georg.brandl components: Documentation, Interpreter Core messages: 93909 nosy: georg.brandl, jess.austin severity: normal status: open title: str.join() should be documented as taking an iterable type: behavior versions: Python 2.4, Python 2.5, Python 2.6, Python 2.7, Python 3.0, Python 3.1 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7116 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue2706] datetime: define division timedelta/timedelta
Jess Austin jess.aus...@gmail.com added the comment: A comment on the two most recent patches... For both of these, we can do the following: from datetime import timedelta td = timedelta(12) td datetime.timedelta(12) td //= 3 td datetime.timedelta(4) td //= timedelta(2) td 2 # CHANGED VARIABLE TYPE! I think the last operation will trap unsuspecting programmers, and provide no benefit for the savvy. There really is no reason to allow an in-place operation like this to change the type of the variable so drastically. (That is, I realize a similar thing could happen with ints and floats, but it seems worse with timedeltas and ints.) I feel the last operation should raise a TypeError, even though it would be quite valid for a non-in-place operation. -- nosy: +jess.austin ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue2706 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5530] datetime class names should obey PEP 8 CapWords convention
New submission from Jess Austin jess.aus...@gmail.com: Class names that comply with the CapWords naming convention described in PEP 8 (http://www.python.org/dev/peps/pep-0008/) are preferred. See the recent discussion that included the BDFL's recommendations at http://mail.python.org/pipermail/python-dev/2009-March/086684.html. Per those recommendations, the attached patch updates every class to expose a CapWords name to python: datetime.timedelta -- datetime.TimeDelta datetime.date -- datetime.Date datetime.tzinfo -- datetime.TZInfo datetime.time -- datetime.Time datetime.datetime -- datetime.DateTime In addition, the old lowercase names are reproduced as derived classes, the methods of which throw PendingDeprecationWarning, and the docstrings of which advise using the new CapWords class names. The test_datetime.py unit test is updated to check for proper functionality and for the presence of the pending deprecation warnings. (This patch relies on the previously-submitted refactoring patch attached to Issue 5520, http://bugs.python.org/issue5520.) Various other tests and support files are updated to use the new CapWords class names. The current patch still fails one test in test_datetime.py, due to previously-existing Issue 5516, http://bugs.python.org/issue5516. This patch includes no documentation updates. -- components: Library (Lib) files: pending_dep.diff keywords: patch messages: 83921 nosy: jess.austin severity: normal status: open title: datetime class names should obey PEP 8 CapWords convention type: behavior versions: Python 3.1 Added file: http://bugs.python.org/file13386/pending_dep.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5530 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5516] equality not reflixive for subclasses of datetime.date and datetime.datetime
