Python 2.x and 3.x use survey, 2014 edition
by Bruno Cauet 17 Dec '14

17 Dec '14

Hi all, Last year a survey was conducted on python 2 and 3 usage. Here is the 2014 edition, slightly updated (from 9 to 11 questions). It should not take you more than 1 minute to fill. I would be pleased if you took that time. Here's the url: http://goo.gl/forms/tDTcm8UzB3 I'll publish the results around the end of the year. Last year results: https://wiki.python.org/moin/2.x-vs-3.x-survey Thank you Bruno

Python 3.4.2/ PyGame Registry
by Matthew Braun 17 Dec '14

17 Dec '14

Good Morning, I installed Python 3.4.2 on my work computer. I was looking at the book "Head First Programming" which references download PYGAME. I downloaded what I believe to be the correct version and it tells me that I don't see the installer. I look in the registry and there is no: *HKEY_CURRENT_USER\Software\Python\* Did I do something wrong? This is all new to me. Any help would be greatly appreciated. Thanks Matt [image: Inline image 1]

Python 2/3 porting HOWTO has been updated
by Brett Cannon 12 Dec '14

12 Dec '14

It now promotes using tooling as much as possible to automate the process of making code by Python 2/3 source-compatible: https://docs.python.org/3.5/howto/pyporting.html Blog post about it at http://nothingbutsnark.svbtle.com/commentary-on-getting-your-code-to-run-on… .

Issue 22919: Update PCBuild for VS 2015
by Steve Dower 12 Dec '14

12 Dec '14

FYI, I've just committed these changes (http://bugs.python.org/issue22919). There shouldn't be any immediate failures, as the updated projects will still build with VS 2010, but our Windows developers/buildbots can migrate onto the later tools as they feel comfortable. I know there are at least a few bugs coming out of the new compiler, so I'll be tracking those down and fixing things. Feel free to nosy me (or Windows) on the issue tracker if you find anything. Cheers, Steve

[RELEASE] Python 2.7.9
by Benjamin Peterson 10 Dec '14

10 Dec '14

It is my pleasure to announce the release of Python 2.7.9, a new bugfix release in the Python 2.7 series. Despite technically being a maintenance release, Python 2.7.9 includes several majors changes from 2.7.8: - The "ensurepip" module has been backported to Python 2.7 - Python 3's ssl module has been backported to Python 2.7. - HTTPS certificates are now verified by default using the system's certificate store. - SSLv3 has been disabled by default due to the POODLE attack. Downloads are at https://www.python.org/downloads/release/python-279/ Please report bugs to https://bugs.python.org/ I would like to thank the people who made the above security and usability improvements listed above possible. Among others, Alex Gaynor, David Reid, Nick Coghlan, and Donald Stufft wrote many PEPs and a lot of code to bring those features to 2.7.9. Thank you. Enjoy, Benjamin 2.7 release manager on behalf on python-dev and all of Python's contributors

Hi there I was visiting you buildbot page for inspiration and found that i apparently have the option to force stop/start all your builds without any access control. You may want to put something to enforce access control? /pedersen

IronPython 2.7.5 Released
by Jeff Hardy 09 Dec '14

09 Dec '14

On behalf of the IronPython team, I'm very happy to announce the release of IronPython 2.7.5[1]. Like all IronPython 2.7-series releases, .NET 4 is required to install it. Installing this release will replace any existing IronPython 2.7-series installation. Assemblies for embedding are provided for .NET 3.5, .NET 4, .NET 4.5, and Silverlight 5. IronPython 2.7.5 is primarily a collection of bug fixes[2] which smooths off many of the remaining rough edges. The complete list of changes[3] is also available. A major new feature is the inclusion of `ensurepip`, which will install the `pip` package manager: ``` ; -X:Frames is required when using pip ipy.exe -X:Frames -m ensurepip ; Run from an Administrator console if using IronPython installer ipy.exe -X:Frames -m pip install html5lib ``` **Note:** The assembly version of IronPython has changed to 2.7.5.0. All previous 2.7 versions had the same version (2.7.0.40) which caused issues when different versions were installed. Publisher policy files are used to so that applications don't have to be recompiled, but recompiling is strongly recommended. A huge thanks goes out to Pawel Jasinski, who contributed most of the changes in this release. Thanks is also due to Simon Opelt, Alex Earl, Jeffrey Bester, yngipy hernan, Alexander Köplinger,Vincent Ducros, and fdanny. For Visual Studio integration, check out Python Tools for Visual Studio[4] which has support for IronPython as well as CPython, and many other fantastic features. IronPython 2.7.5 is also available for embedding via NuGet. The main package is IronPython, and the standard library is in IronPython.StdLib. - Jeff [1] http://ironpython.codeplex.com/releases/view/169382 [2] http://bit.ly/ipy275fixed [3] https://github.com/IronLanguages/main/compare/ipy-2.7.4...ipy-2.7.5 [4] http://pytools.codeplex.com/

MicroPython 1.3.7 released
by Paul Sokolovsky 08 Dec '14

08 Dec '14

Hello, MicroPython is a Python3 language implementation which scales down to run on microcontrollers with tens of Ks of RAM and few hundreds of Ks of code size. Besides microcontrollers, it's also useful for small embedded Linux systems, where storage space is limited, for embedding as a scripting engine into standalone applications, where quick startup time is needed, etc. http://micropython.org/ https://github.com/micropython/micropython It went several months since the original announcement of MicroPython 1.0 (https://mail.python.org/pipermail/python-list/2014-June/672994.html), there were number of releases in the meantime, but we were too busy implementing new features, so this announcement provides just high-level overview of changes: * Basic Unicode support added (thanks to Chris Angelico for driving the effort) * More functionality of standard types and functions are implemented (for example, MicroPython can run subset of http.client module functionality from CPython3 stdlib). * Highly optimized for code size implementations of important Python modules are added. There offer subset of functionality and prefixed with "u". For example, ure, uheapq, uzlib, uhashlib, ubinascii are provided. * Lots of microcontroller hardware bindings added and generalized. Besides core interpreter, there's also good progress on modules and applications: * MicroPython standard library project, https://github.com/micropython/micropython-lib , an effort to port/develop as much as possible Python stdlib modules to MicroPython, has good progress, with few dozens of modules available on PyPI already (pip-micropython wrapper is provided to install them). * An asyncio subset implementation, dubbed "uasyncio", is available and should be stable enough. * Proof of concept web microframework, "picoweb", based on uasyncio is being developed: https://github.com/pfalcon/picoweb * Lots of other projects available on github. Reference implementation of MicroPython runs on a microcontroller board with 1Mb Flash and 128Kb RAM, which should offer good platform for people interested in microcontroller usage (more info: http://micropython.org/). MicroPython can also be easily built and supported on Linux, MacOSX, and Windows systems (more info: https://github.com/micropython/micropython) -- Best regards, Paul mailto:pmiscml@gmail.com
