[RELEASED] Python 2.7 beta 2
by Benjamin Peterson May 8, 2010

May 8, 2010

On behalf of the Python development team, I'm elated to announce the second beta 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. 2.7 will have an extended period of bugfix maintenance. 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/ While this is a development release and is thus not suitable for production use, we encourage Python application and library developers to test the release with their code and report any bugs they encounter to: http://bugs.python.org/ 2.7 documentation can be found at: http://docs.python.org/2.7/ Enjoy! -- Benjamin Peterson 2.7 Release Manager benjamin at python.org (on behalf of the entire python-dev team and 2.7's contributors)

[ANN] Pyspread 0.1.1 released
by Martin Manns May 8, 2010

May 8, 2010

Pyspread 0.1.1 released ======================= I am pleased to announce the new release 0.1.1 of pyspread. About: ------ Pyspread is a cross-platform Python spreadsheet application. It is based on and written in the programming language Python. Instead of spreadsheet formulas, Python expressions are entered into the spreadsheet cells. Each expression returns a Python object that can be accessed from other cells. These objects can represent anything including lists or matrices. Pyspread runs on Linux and *nix platforms with GTK support as well as on Windows (XP and Vista tested). On Mac OS X, some icons are too small but the application basically works. Homepage -------- http://pyspread.sourceforge.net Changes to 0.1 -------------- * Grid is faster. * Copying only partly filled cells works now. * Cells that get attributes but no string no longer display None. Enjoy Martin

[ANN] PythonQt 2.0 released
by Florian Link May 8, 2010

May 8, 2010

Embedding Python into your Qt / C++ application and accessing the whole Qt API from within your Python scripts is right at your hands with the new PythonQt 2.0 release. http://pythonqt.sourceforge.net/ PythonQt consists of a small dynamic library that offers scripting QObjects and interaction between Qt and Python in both directions, mostly in the spirit of QtScript, but for Python. In addition to that, the core library can be extended using the new wrapper generator to support raw C++ classes. PythonQt comes with pregenerated wrappers for most Qt modules. Note: The focus of PythonQt is embedding Python into your existing Qt application (to make some aspects of it scriptable), and not to create the whole application in Python. If you are looking for that, go for PyQt or PySide! The main features of this update are: - a new wrapper generator (based on the qtscript generator) that generates Python wrappers for (almost) the complete Qt framework - support for multiple inheritance of wrapped C++ classes - support for polymorphic downcast (e.g., QEvent will get its derived type based on the type id) - dynamic property support (both setting and getting via normal python attributes) - public member variable wrapping (for QStyleOptions and derived classes) - full support for operators (so that QPoint, QSize etc. can be used with operators in Python) - automatic casting for special classes (QPen/QBrush/GlobalColor enum/...) - deriving C++ objects from Python to implement virtual functions (experimental feature) With this release, the feature set of PythonQt comes much closer to what PyQt and PySide offer, it is now possible to create complex GUIs using PythonQt and you could delegate large parts of your C++ application to Python scripting (e.g., to let users customize the GUI, to support Python plugins in your application, your idea goes here...). regards, Florian

pytest-xdist 1.2: distributed testing getting stable
by holger krekel May 5, 2010

May 5, 2010

pytest-xdist 1.2 brings bug fixes and improved stability for distributed testing with py.test. This plugin allows to ad-hoc distribute test runs to multiple CPUs, different Python interpreters or remote machines. It requires setuptools or distribute which help to pull in the neccessary execnet and pytest-core dependencies. See here for extensive docs: http://pytest.org/plugin/xdist.html best, holger 1.2 ------------------------- - fix issue79: sessionfinish/teardown hooks are now called systematically on the slave side - introduce a new data input/output mechanism to allow the master side to send and receive data from a slave. - fix race condition in underlying pickling/unpickling handling - use and require new register hooks facility of py.test>=1.3.0 - require improved execnet>=1.0.6 because of various race conditions that can arise in xdist testing modes. - fix some python3 related pickling related race conditions - fix PyPI description
