ANN: Spyder v2.1.10
by Pierre Raybaut 26 May '12

26 May '12

Hi all, On the behalf of Spyder's development team (http://code.google.com/p/spyderlib/people/list), I'm pleased to announce that Spyder v2.1.10 has been released and is available for Windows XP/Vista/7, GNU/Linux and MacOS X: http://code.google.com/p/spyderlib/ This is a pure maintenance release -- a lot of bugs were fixed since v2.1.9: http://code.google.com/p/spyderlib/wiki/ChangeLog Spyder is a free, open-source (MIT license) interactive development environment for the Python language with advanced editing, interactive testing, debugging and introspection features. Originally designed to provide MATLAB-like features (integrated help, interactive console, variable explorer with GUI-based editors for dictionaries, NumPy arrays, ...), it is strongly oriented towards scientific computing and software development. Thanks to the `spyderlib` library, Spyder also provides powerful ready-to-use widgets: embedded Python console (example: http://packages.python.org/guiqwt/_images/sift3.png), NumPy array editor (example: http://packages.python.org/guiqwt/_images/sift2.png), dictionary editor, source code editor, etc. Description of key features with tasty screenshots can be found at: http://code.google.com/p/spyderlib/wiki/Features On Windows platforms, Spyder is also available as a stand-alone executable (don't forget to disable UAC on Vista/7). This all-in-one portable version is still experimental (for example, it does not embed sphinx -- meaning no rich text mode for the object inspector) but it should provide a working version of Spyder for Windows platforms without having to install anything else (except Python 2.x itself, of course). Don't forget to follow Spyder updates/news: * on the project website: http://code.google.com/p/spyderlib/ * and on our official blog: http://spyder-ide.blogspot.com/ Last, but not least, we welcome any contribution that helps making Spyder an efficient scientific development/computing environment. Join us to help creating your favourite environment! (http://code.google.com/p/spyderlib/wiki/NoteForContributors) Enjoy! -Pierre

by Mike Müller 24 May '12

24 May '12

There are still a couple of places left in our upcoming Python course for programmers in the beginning of June. Three intensive days of training with answers to your questions about Python. Python for Programmers ---------------------- You know another programming language and would like to learn Python? This course teaches you all the basics to write useful Python programs. It is hands-on with plenty of exercises and also provides sound knowledge how Python does things. Date: 05.06.-07.06.2012 Location: Leipzig, Germany Trainer: Mike Müller Course Language: English Link: http://www.python-academy.com/courses/python_course_programmers.html Other courses you might be interested in: Python for Non-Programmers -------------------------- Introduction to Python for participants without prior programming experience. You need to know how to use a computer and be willing to learn a new ways to tell the computer what to do. Date: 04.06.-07.06.2012 Location: Leipzig, Germany Trainer: Mike Müller Course Language: English Link: http://www.python-academy.com/courses/python_course_nonprogrammers.html Advanced Python --------------- You would like to learn more about metaclasses, decorators, descriptors, context managers, comprehensions, patterns and good Python programming practices? This courses teaches all this with plenty of hands-on examples that makes these, admittedly somewhat involved topics, accessibly to everybody with intermediate Python experience. Date: 08.06.-10.06.2012 Location: Leipzig, Germany Trainer: Mike Müller Course Language: English Link: http://www.python-academy.com/courses/specialtopics/python_course_advanced.… HPC with Python --------------- "High-Performance Computation with Python" is the new kid in the block. This course is designed to give you a solid foundation to improve the run time of your Python programs and write efficient algorithms. The ingredients are use of the right data structure for the problem, extension in other languages, Cython and NumPy. There five course that can be booked separately. See below for more details. Date: 11.06.-15.06.2012 Location: Leipzig, Germany Trainer: Mike Müller, Stefan Behnel Course Language: English Link: http://www.python-academy.com/courses/python_course_high_performance.html Optimizing of Python Programs ++++++++++++++++++++++++++++++ Learn how to profile programs, choose the right data structures and algorithms for the right purpose and get some hands-on experience in making Python programs faster with comparable little modifications. Python Extensions with Other Languages ++++++++++++++++++++++++++++++++++++++ Learn about options to connect Python to other languages starting form Python's C-API and hand-written extensions the tour looks a Cython, ctypes, SWIG, Jython, Ironpython, and even f2py to connect with Fortran. Fast Code with the Cython Compiler ++++++++++++++++++++++++++++++++++ In-depth coverage of Cython with Cython core developer Stefan Behnel. No question about writing extensions and using external C libraries with Cython should remain unanswered after this day.

Uliweb release 0.1 version
by limodou 24 May '12

24 May '12

http://pypi.python.org/pypi/Uliweb/0.1 About Uliweb ---------------- Uliweb is a Python based web framework. This project was created and lead by Limodou <limodou(a)gmail.com>. License ------------ Uliweb is released under BSD license. Infrastructure ---------------- Uliweb was not created totally from scratch. It uses some modules created by other developers, for example: * Werkzeug Used to handle core processes in the framework. For example: command line tools , URL Mapping, Debug, etc. * SqlAlchemy The ORM based on it. Developers can access databases, or use the module separately. I also referenced some code from other web frameworks, for example: * The Templating system is styled after the one used in web2py several improvements were made. I also constructed a few new "wheels" myself. For example: * Form processing module. Developers can use it to create HTML code, validate submitted data and convert submitted data to Python data types. * I18n processing including template support, language lazy process. * Uliorm, which is an ORM module, was built on top of SqlAlchemy. I also referenced from GAE datastore module. * Framework runtime process. * Plugin mechanism, styled after the one used in the UliPad project. Features ----------- * Organization * MVT(Model View Template) development model. * App-based project structure. Uliweb organizes a project with small apps. Each app can have its own configuration file(settings.ini), template directory, and static directory. Existing apps can be easily reused, but are treated as a compound. web application project if configured as such. Developers can also reference static files and templates between apps, thus easing inter-application data exchange. All apps in a project are loaded by default if INSTALLED_APPS is not configured in the configuration file. All separate app configuration files are automatically processed at project startup. * URL Mapping Flexiable and powerful URL mapping. Uliweb uses werkzeug's routing module. User can easily define a URL, which in turn can be easily bound with a view function. URLs can also be created reversely according to the view function name. It supports argument definitions in URLs and default URL mapping to a view function. * View and Template View templates can be automatically applied. If you return a dict variable from view function, Uliweb will automatically try to match and apply a template according to the view function name. And now, Uliweb also support Class View style. I hope you can enjoy it. * Environment execution mode Each view function will be run in an environment, which eliminates the need to write many import statements. Plus there are already many objects that can be used directly, for example: request, response, etc. This is DRY and saves a lot of coding Developers can directly use Python code in a template, the Python code does not neede to be indented as long as a pass statement is added at the end of each code block. Uliweb also supports child template inclusion and inheritance. * ORM Uliorm is the default ORM module but not configured by default. Developers are free to use any ORM module as preferred. Uliorm supports model creation and automatic database migiration(table creation and table structure modification). * I18n Can be used in python and template files. Browser language and cookie settings are supported including automatic language switching. Provides a command line tool that developers can use to extract .po files. This can happen either at the app level or project level process. It can automatically merge .pot files to existing .po files. * Extension Dispatch extension. This is a dispatch processing mechanism that utilizes different types of dispatch points. So you can write procedures to carry out special processes and bind them to these dispatch points. For example, database initicalization, I18n process initialization, etc. * Middleware extension It's similar to Djangos. You can configure it in configuration files. Each middleware can process the request and response objets. Special function calls in the views module initial process. If you write a special function named begin, it'll be processed before any view function can be processed, this allows developers to do some module level processing at that point, for example: check the user authentication, etc. * Command Line Tools * Create app, and include the basic essential directory structure, files and code. * Export static files, you can export all available apps' static files to a special directory. * Startup a development web server thats supports debugging and autoreload. * Deployment * Supports easy deployment on the GAE platform. * Supports mod_wsgi, cgi, fast_cgi, scgi, uwsgi. * Development Provide a development server, and can be automatically reload when some module files are modified. * Misc. Various demos are available for anyone interested in learning more about Uliweb. It includes all core codes and also all source code of uliwebproject , and some other demo codes, which can be used directly/freely as you wish. * static file serving support. Uliweb supports static file access directly, and it can also process HTTP_IF_MODIFIED_SINCE and return static file content in trunk. Principle ---------- * Simple and easy to use web framework. * Reusability and configurable are the main ideas about Uliweb. * The web framework should be flexiable and easy to extend. Links -------- * Plugs is a Uliweb apps collection project, you can visit it at https://github.com/limodou/plugs * uliweb-doc is a documentation project of Uliweb, you can visit it at https://github.com/limodou/uliweb-doc, and you can also read the compiled documentation at http://uliweb.rtfd.org * uliwebzone is a community project of Uliweb, you can visit it at https://github.com/limodou/uliwebzone. -- I like python!

StoryText 3.7 - GUI testing tool
by Geoff Bache 23 May '12

23 May '12

Hi all, The 3.7 release features the following: Many improvements to SWT/Eclipse RCP support, including support for GEF applications. Many improvements to wxPython support, status changed from Alpha to Beta. Support for Python 3 and Tkinter added. Shortcuts can now be parametrized. Many bugfixes. Regards, Geoff Bache A bit more detail: StoryText is an unconventional GUI testing tool for PyGTK, Tkinter, wxPython, Swing and SWT along with a Python framework for testing 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 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.
