[RELEASED] Python 2.7 alpha 4
by Benjamin Peterson 06 Mar '10

06 Mar '10

On behalf of the Python development team, I'm overjoyed to announce the fourth alpha release of Python 2.7. Python 2.7 is scheduled (by Guido and Python-dev) to be the last major version in the 2.x series. Though more major releases have not been absolutely ruled out, it's likely that the 2.7 release will an extended period of maintenance for the 2.x series. 2.7 includes many features that were first released in Python 3.1. The faster io module, the new nested with statement syntax, improved float repr, set literals, dictionary views, and the memoryview object have been backported from 3.1. Other features include an ordered dictionary implementation, unittests improvements, a new sysconfig module, and support for ttk Tile in Tkinter. For a more extensive list of changes in 2.7, see http://doc.python.org/dev/whatsnew/2.7.html or Misc/NEWS in the Python distribution. To download Python 2.7 visit: http://www.python.org/download/releases/2.7/ Please note that this is a development release, intended as a preview of new features for the community, and is thus not suitable for production use. The 2.7 documentation can be found at: http://docs.python.org/2.7 Please consider trying Python 2.7 with your code and reporting any bugs you may notice to: http://bugs.python.org Enjoy! -- Benjamin Peterson 2.7 Release Manager benjamin at python.org (on behalf of the entire python-dev team and 2.7's contributors)

[RELEASED] Python 3.1.2 release candidate
by Benjamin Peterson 06 Mar '10

06 Mar '10

On behalf of the Python development team, I'm pleased to announce a release candidate for the second bugfix release of the Python 3.1 series, Python 3.1.2. This bug fix release fixes numerous issues found in 3.1.1. This release candidate has been released to solicit testing and feedback over an possible regressions from 3.1.1. Please consider testing it with your library or application and reporting an bugs you encounter. This will help make the final 3.1.2 release, planned in 2 weeks time, all the more stable. The Python 3.1 version series focuses on the stabilization and optimization of the features and changes that Python 3.0 introduced. For example, the new I/O system has been rewritten in C for speed. File system APIs that use unicode strings now handle paths with undecodable bytes in them. Other features include an ordered dictionary implementation, a condensed syntax for nested with statements, and support for ttk Tile in Tkinter. For a more extensive list of changes in 3.1, see http://doc.python.org/3.1/whatsnew/3.1.html or Misc/NEWS in the Python distribution. To download Python 3.1.2rc1 visit: http://www.python.org/download/releases/3.1.2/ A list of changes in 3.1.2rc1 can be found here: http://svn.python.org/projects/python/tags/r312rc1/Misc/NEWS The 3.1 documentation can be found at: http://docs.python.org/3.1 Bugs can always be reported to: http://bugs.python.org Enjoy! -- Benjamin Peterson Release Manager benjamin at python.org (on behalf of the entire python-dev team and 3.1.2's contributors)

ANN: PyUseCase 3.2.1 - GUI testing for PyGTK and Tkinter
by Geoff Bache 05 Mar '10

05 Mar '10

Hi all, I've made a couple of bugfixes to the 3.2 release from last week. Regards, Geoff Bache A bit more detail: PyUseCase is an unconventional GUI testing tool for PyGTK and Tkinter, along with a framework for testing Python GUIs in general. Instead of recording GUI mechanics directly, it asks the user for descriptive names and hence builds up a "domain language" along with a "UI map file" that translates this language into actions on the current GUI widgets. The point is to reduce coupling, allow very expressive tests, and ensure that GUI changes mean changing the UI map file but not all the tests. Instead of an "assertion" mechanism, it auto-generates a log of the GUI appearance and changes to it. The point is then to use that as a baseline for text-based testing, using e.g. TextTest. It also includes support for instrumenting code so that "waits" can be recorded, making it far easier for a tester to record correctly synchronized tests without having to explicitly plan for this.

PyCon ITALY Call for Paper is officially open!
by Simone Zinanni 05 Mar '10

05 Mar '10

The conference is composed of three parallel tracks: 1) the Discovering Python track will primarily focus on introductory topics about Python libraries, frameworks and technologies; 2) the Spreading Python track will focus both on advanced technical topics and related matters like development methodologies, real-world use cases and management techniques; 3) the Learning Python track will feature a continuous interaction between the speaker and the audience: the speaker will propose a topic and introduce a possible solution, then the talk will dynamically evolve, naturally following questions and notes from the audience. Talks could focus on the following topics (the list is neither exclusive nor exaustive): * vast and/or distributed applications written in Python; * scientific and computationally intensive applications; * interaction with other languages/environments, RPC, services; * web programming and web frameworks (Django, Zope, Pylons, ecc.); * concurrent/distributed programming (Twisted, Tornado, Eventlet, ecc.); * desktop programming and GUI toolkits; * Python as "scripting" language (system administration, COM, etc...); * Python and databases; * Python as an educational language; Each talk will have one of the following duration: 45, 60 or 90 approximately, inclusive of the time for the audience to enter and leave the room. Please specify which length best fit your contents: some flexibility is available to arrive at the best overall scheduling. For more info please visit: http://www.pycon.it/blog/2010/02/10/pycon4-call-for-papers-open http://www.pycon.it/pycon4/call-for-paper
