Search-friendly shortcuts for Windows?
by Nick Coghlan 22 Dec '10

22 Dec '10

Something I noticed after installing the 3.2 beta on my Windows 7 laptop is that the start menu shortcuts aren't particularly search friendly. Searching loses the heirarchical information, so attempting to directly locate "pyt" provides two separate "Python Command Line" shortcuts, with no indicator as to which one will start which version. Given the changing dynamics of the desktop launch menus to better support direct access as an alternative to hierarchical navigation, would it be reasonable to consider including the major version number in the start menu shortcut names? (Question is mainly for Martin, obviously, but I'm also curious if anyone else has encountered the same thing) Regards, Nick. -- Nick Coghlan | ncoghlan(a)gmail.com | Brisbane, Australia

[RELEASED] Python 3.2 beta 2
by Georg Brandl 21 Dec '10

21 Dec '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the Python development team, I'm happy to announce the second beta preview release of Python 3.2. Python 3.2 is a continuation of the efforts to improve and stabilize the Python 3.x line. Since the final release of Python 2.7, the 2.x line will only receive bugfixes, and new features are developed for 3.x only. Since PEP 3003, the Moratorium on Language Changes, is in effect, there are no changes in Python's syntax and built-in types in Python 3.2. Development efforts concentrated on the standard library and support for porting code to Python 3. Highlights are: * numerous improvements to the unittest module * PEP 3147, support for .pyc repository directories * PEP 3149, support for version tagged dynamic libraries * PEP 3148, a new futures library for concurrent programming * PEP 384, a stable ABI for extension modules * PEP 391, dictionary-based logging configuration * an overhauled GIL implementation that reduces contention * an extended email package that handles bytes messages * countless fixes regarding bytes/string issues; among them full support for a bytes environment (filenames, environment variables) * many consistency and behavior fixes for numeric operations * a sysconfig module to access configuration information * a pure-Python implementation of the datetime module * additions to the shutil module, among them archive file support * improvements to pdb, the Python debugger For a more extensive list of changes in 3.2, see http://docs.python.org/3.2/whatsnew/3.2.html To download Python 3.2 visit: http://www.python.org/download/releases/3.2/ Please consider trying Python 3.2 with your code and reporting any bugs you may notice to: http://bugs.python.org/ Enjoy! - -- Georg Brandl, Release Manager georg at python.org (on behalf of the entire python-dev team and 3.2's contributors) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEARECAAYFAk0Q/aAACgkQN9GcIYhpnLDf8gCgkLGAsE+T3R505jZc1RxXDYsa NSsAnRGaFjeTm9o2Z5O8FuIzTUG8t1PT =hHzz -----END PGP SIGNATURE-----

sqlite, DDL, and transactions
by Scott Urban 20 Dec '10

20 Dec '10

Hi The python sqlite module automatically commits open transactions when it encounters a DDL statement. This is unnecessary; DDL is transaction in my testing (see attached). Attached patch addresses the issue. Patch is against 2.6.1, but looking at Trunk in svn, it seems like the patch is needed and would apply. One issue I could foresee is that this behavior might depend on the sqlite version in use (I'm on 3.6.10). Thanks Scott

Locale-specific formatting
by MRAB 20 Dec '10

20 Dec '10

I had a thought about locale-specific formatting. Currently, when we want to do locale-specific formatting we use the locale module like this: >>> locale.format("%d", 12345, grouping=False) '12345' >>> locale.format("%d", 12345, grouping=True) '12,345' This makes it harder to use more than one locale at a time, or one which is different from the default. My thought was that we could specify a locale in the format specification mini-language and the parameter list of str.format, something like this: >>> loc = locale.getlocale() >>> "{0:@1}".format(12345, loc) '12345' >>> "{0:,@1}".format(12345, loc) '12,345' ... >>> "UK says {value:,.1f@uk} and France says {value:,.1f@france}".format(value=12345, uk=uk_loc, france=france_loc) 'UK says 1,234.5 and France says 1 234,5' Comments?

A grammatical oddity: trailing commas in argument lists -- continuation
by Jan Kaliszewski 18 Dec '10

18 Dec '10

Dear Python Developers, It is s my first post to python-dev, so let me introduce myself briefly: Jan Kaliszewski, programmer and composer, sometimes also NGO activist. Coming to the matter... The discussion started with remark by Mark Dickinson about such a syntax oddity: > def f(a, b,): ... is fine, but > def f(*, a, b,): ... is a SyntaxError Then some other similar oddities were pointed at (*args/**kwargs-related ones as well as calls like f(*, a=3,) causing SyntaxError too). References: * http://mail.python.org/pipermail/python-dev/2010-July/101636.html * http://bugs.python.org/issue9232 * http://bugs.python.org/issue10682 But yesterday both mentioned issues has been closed as rejected -- with suggestion that it would probably require a PEP to modify Python in this aspect (as there is no clear consensus). So I'd opt for re-opening the discussion -- I suppose that more people could be interested in solving the issue (at least after the end of PEP 3003 moratorium period). I think that seeing that: def f(a, b): ... def f(a, b,): ... def f(a, *, b): ... def f(a, *args, b): ... x(1, 2, 3, 4, z=5) x(1, 2, 3, 4, z=5,) x(1, *(2,3,4), z=5) ...are ok, then -- def f(a, *, b,): ... def f(a, *args, b,): ... x(1, *(2,3,4), z=5,): ... ...should be ok as well, and consequently -- def f(a, *args,): ... def f(a, **kwargs,): ... x(1, *(2,3,4),) x(1, **dict(z=6),) ...should also be ok. Please also note that Py3k's function annotations make one-def-argument- -per-line formattig style the most suitable in some cases, e.g.: def my_func( spam:"Very tasty and nutritious piece of food", ham:"For experts only", *more_spam:"Not less tasty and not less nutritious!", spammish_inquisition:"Nobody expects this!", ) -> "Spam, spam, spam, spam, spam, spam, spam, spam, spam, spam": ... Regards, Jan Kaliszewski
