[ANN] PyYAML-3.13: YAML parser and emitter for Python
by Ingy dot Net July 5, 2018

July 5, 2018

======================== Announcing PyYAML-3.13 ======================== A new bug fix release of PyYAML is now available: http://pyyaml.org/wiki/PyYAML *** Important Note From Maintainers *** This is the first PyYAML release by the new maintainers. It was made critical because PyYAML-3.12 did not work with the recent Python 3.7 release. A more ambitious 4.1 release was attempted last week and needed to be retracted for many reasons. We apologize any pain caused by the 4.1 removal, but we remain confident that it was the best decision. There are over 60 pull requests in PyYAML and LibYAML that will be represented in the upcoming 4.2 release and we are working hard to get those to you as soon as the release is ready (but no sooner :). We are are excited that the PyYAML project is moving forward again. -- The PyYAML Maintenance Team Changes ======= * Rebuilt with the latest Cython to support the new Python 3.7 release. * No functionality is different from PyYAML 3.12 in this release. Resources ========= PyYAML IRC Channel: #pyyaml on irc.freenode.net YAML IRC Channel: #yaml-dev on irc.freenode.net LibYAML IRC Channel: #libyaml on irc.freenode.net PyYAML homepage: http://pyyaml.org/wiki/PyYAML PyYAML documentation: http://pyyaml.org/wiki/PyYAMLDocumentation Source and binary installers: https://pypi.python.org/pypi/PyYAML/3.13 GitHub repository: https://github.com/yaml/pyyaml/ Bug tracking: https://github.com/yaml/pyyaml/issues YAML homepage: http://yaml.org/ YAML-core mailing list: http://lists.sourceforge.net/lists/listinfo/yaml-core About PyYAML ============ YAML is a data serialization format designed for human readability and interaction with scripting languages. PyYAML is a YAML parser and emitter for Python. PyYAML features a complete YAML 1.1 parser, Unicode support, pickle support, capable extension API, and sensible error messages. PyYAML supports standard YAML tags and provides Python-specific tags that allow to represent an arbitrary Python object. PyYAML is applicable for a broad range of tasks from complex configuration files to object serialization and persistance. Example ======= >>> import yaml >>> yaml.load(""" ... name: PyYAML ... description: YAML parser and emitter for Python ... homepage: http://pyyaml.org/wiki/PyYAML ... keywords: [YAML, serialization, configuration, persistance, pickle] ... """) {'keywords': ['YAML', 'serialization', 'configuration', 'persistance', 'pickle'], 'homepage': 'http://pyyaml.org/wiki/PyYAML', 'description': 'YAML parser and emitter for Python', 'name': 'PyYAML'} >>> print yaml.dump(_) name: PyYAML homepage: http://pyyaml.org/wiki/PyYAML description: YAML parser and emitter for Python keywords: [YAML, serialization, configuration, persistance, pickle] Maintainers =========== The following people are currently responsible for maintaining PyYAML: * Ingy döt Net * Tina Mueller * Matt Davis and many thanks to all who have contribributed!

Vulture 0.28
by Jendrik Seipp July 5, 2018

July 5, 2018

Vulture - Find dead code ======================== Vulture finds unused code in Python programs. This is useful for cleaning up and finding errors in large code bases. If you run Vulture on both your library and test suite you can find untested code. Due to Python's dynamic nature, static code analyzers like Vulture are likely to miss some dead code. Also, code that is only called implicitly may be reported as unused. Nonetheless, Vulture can be a very helpful tool for higher code quality. Download ======== https://github.com/jendrikseipp/vulture http://pypi.python.org/pypi/vulture Features ======== * fast: uses static code analysis * tested: tests itself and has complete test coverage * complements pyflakes and has the same output syntax * sorts unused classes and functions by size with ``--sort-by-size`` * supports Python 2.7 and Python >= 3.4 News ==== * Add ``--make-whitelist`` flag for reporting output in whitelist format (thanks @RJ722). * Ignore case of ``--exclude`` arguments on Windows. * Add ``*-test.py`` to recognized test file patterns. * Add ``failureException``, ``longMessage`` and ``maxDiff`` to ``unittest`` whitelist. * Refer to actual objects rather than their mocks in default whitelists (thanks @RJ722). * Don't import any Vulture modules in setup.py (thanks @RJ722). Cheers Jendrik

PyCon ZA 2018 - Second Call for Speakers
by Neil Muller July 4, 2018

July 4, 2018

This is a second call for talk proposals for PyCon ZA 2018. While we've already received several great talk proposals, we still have a number of open talk slots and are thus keen to see further talk submissions. PyCon ZA 2018 will take place on the 11th & 12th of October at The Birchwood Hotel & Conference Centre, in Boksburg North, Johannesburg, South Africa (location link: https://goo.gl/maps/XMtwhJCKVt92 ). There will also be tutorial sessions the day before the conference (the 10th) and we will hold sprints on the 13th & 14th of October. We are currently accepting proposals for talks. If you would like to give a presentation, please register at https://za.pycon.org/ and submit your proposal, following the instructions at https://za.pycon.org/talks/submit-talk . We have a number of tracks available, including: Web, Scientific-Computing/PyData, Testing and Other (which includes all talks that don't fall under the mentioned tracks). Talk submissions close io the 31st of August 2018, ad we hope to inform speakers by the second week of September. If you need an earlier decision for travel planning, please add a note with your deadline to your submission. The presentation slots will be 30 minutes long, with an additional 10 minutes for discussion at the end. Shared sessions are also possible. The presentations will be in English. PyCon ZA offers a mentorship program for inexperienced speakers. If you would like assistance preparing your submission, email team(a)za.pycon.org with a rough draft of your talk proposal and we'll find a suitable experienced speaker to act as a mentor. In addition to talks, we are also looking for proposals for tutorials, demos, sprints and open spaces. Tutorials will be held before the conference and are expected to provided in-depth coverage of a topic. The number of attendees will be also be limited. We are accepting proposals for either half day (4 hours) or full-day (8 hours) tutorials. The deadline for tutorial submissions is the 27th of July 2018, and we'll inform people of our decision in early August. Demos are cool things for attendees to see and interact with. Open spaces are open discussion forums where communities with a common interest gather to present views, ask questions and meet people interested in the topic. Sprints are coding efforts and hack days that happen after the conference. There is no need to register a sprint or open space topic upfront, but doing so allows us to advertise them during the conference. Limited financial assistance for attendees is available. See https://za.pycon.org/financial-aid/ for details on how to apply. Each submission will be reviewed on a case-by-case basis. -- Neil Muller On behalf of the PyCon ZA organising committee
