[baseline 0.2.1] Easy String Baseline
by Dan Gass March 30, 2020

March 30, 2020

I am please to announce the availability of the "baseline" package. This tool streamlines creation and maintenance of tests which compare string output against a baseline. It offers a mechanism to compare a string against a baselined copy and update the baselined copy to match the new value when a mismatch occurs. The update process includes a manual step to facilitate a review of the change before acceptance. The tool uses multi-line string format for string baselines to improve readability for human review. Docs: https://baseline.readthedocs.io/en/latest/ PyPi: https://pypi.org/project/baseline/ Repo: https://github.com/dmgass/baseline License: MIT With Regards, Dan Gass (dan.gass at gmail) *********** Quick Start *********** Create an empty baseline with a triple quoted multi-line string. Place the ending triple quote on a separate line and indent it to the level you wish the string baseline update to be indented to. Add a compare of the string being tested to the baseline string. Then save the file as ``fox.py``: .. code-block:: python from baseline import Baseline expected = Baseline(""" """) test_string = "THE QUICK BROWN FOX\n JUMPS\nOVER THE LAZY DOG." assert test_string == expected Run ``fox.py`` and observe that the ``assert`` raises an exception since the strings are not equal. Because the comparison failed, the tool located the triple quoted baseline string in the source file and updated it with the miscompared value. When the interpretter exited, the tool saved the updated source file but changed the file name to ``fox.update.py``: .. code-block:: python from baseline import Baseline expected = Baseline(""" THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG. """) test_string = "THE QUICK BROWN FOX\n JUMPS\nOVER THE LAZY DOG." assert test_string == expected After reviewing the change with your favorite file differencing tool, accept the change by either manually overwriting the original file or use the ``baseline`` command line tool to scan the directory for updated scripts and accept them: .. code-block:: shell $ python -m baseline * Found updates for: fox.py Hit [ENTER] to update, [Ctrl-C] to cancel fox.update.py -> fox.py Run ``fox.py`` again and observe the ``assert`` does not raise an exception nor is a source file update generated. If in the future the test value changes, the ``assert`` will raise an exception and cause a new source file update to be generated. Simply repeat the review and acceptance step and you are back in business! <P><A HREF="https://baseline.readthedocs.io/en/latest/"> baseline 0.2.1</A> - Easy String Baseline (07-Jun-18)

[ANN] PyYAML-4.1: ***RETRACTED***
by Ingy dot Net June 28, 2018

June 28, 2018

I am sorry to report that the PyYAML-4.1 release from 48 hours ago has been removed from PyPI There were too many problems to make this a viable release. The biggest known issue with this retraction is that PyYAML will not work with the new Python 3.7 until PyYAML-4.2 is released. https://github.com/yaml/pyyaml/issues/126#issuecomment-401175258 We are starting work immediately on 4.2b1 prerelease series. I hope to see 4.2 released in the next few days. Work is being coordinated on #pyyaml on irc.freenode.net and issues can be reported and followed at https://github.com/yaml/pyyaml Thank you for your patience.

ANN: Lea 3.0 released
by Pierre Denis June 27, 2018

June 27, 2018

Lea 3.0 final is now released! ---> http://pypi.org/project/lea/3.0.0 What is Lea? ------------ Lea is a Python module aiming at working with discrete probability distributions in an intuitive way. It allows you modeling a broad range of random phenomena: gambling, weather, finance, etc. More generally, Lea may be used for any finite set of discrete values having known probability: numbers, booleans, date/times, symbols, . Each probability distribution is modeled as a plain object, which can be named, displayed, queried or processed to produce new probability distributions. Lea also provides advanced functions and Probabilistic Programming (PP) features; these include conditional probabilities, Bayesian networks, joint probability distributions, Markov chains and symbolic computation. Lea can be used for AI, machine learning, education, ... LGPL - Python 2.6+ / Python 3 supported What's new in Lea 3? -------------------- Compared to latest version (2.3.5), many things have changed to extend the usability and openness of the library. To name a few: * ability to choose between different probability representations: floats, fractions and decimals * symbolic computation: Lea can now calculate probability *formula* using the SymPy library (http://www.sympy.org) * simpler API and compliance with PEP8 naming convention * revamped tutorials and examples -> http://bitbucket.org/piedenis/lea/wiki/Home * paper on the "Statues" algorithm used in Lea -> http://arxiv.org/abs/1806.09997 Here is a short sample. A biased coins is flipped with 1/4 chance to be 'head'. Suppose that this coin is thrown 6 times. What is the probability to get no more than two 'heads'? Here is how you could make this calculation in Lea, using successively float, fraction and symbolic representations: print (P(lea.binom(6,1/4) <= 2)) # -> 0.83056640625 print (P(lea.binom(6,'1/4') <= 2)) # -> 1701/2048 print (P(lea.binom(6,'p') <= 2)) # -> (p - 1)**4*(10*p**2 + 4*p + 1)) print (P(lea.binom(6,'p') <= 2).subs('p',1/4)) # -> 0.830566406250000 To learn more... ---------------- Lea 3 on PyPI -> http://pypi.org/project/lea/3.0.0 Lea project page -> http://bitbucket.org/piedenis/lea Documentation -> http://bitbucket.org/piedenis/lea/wiki/Home Statues algorithm -> http://arxiv.org/abs/1806.09997 With the hope that Lea can make the Universe less hazardous, Pierre Denis

wxPython 4.0.3
by Robin Dunn June 27, 2018

June 27, 2018

Announcing wxPython 4.0.3 ========================= PyPI: https://pypi.org/project/wxPython/4.0.3 Extras: https://extras.wxPython.org/wxPython4/extras/ Pip: ``pip install wxPython==4.0.3`` Changes in this release include the following: * Fixed a linking problem on macOS. The new waf added an explicit link to the Python shared library which meant that it would try to load it at runtime, even if a different Python (such as Anaconda, EDM or Homebrew) was used to import wxPython. This, of course, caused runtime errors. (#892) * Sort pages by dock_pos when added to automatic (agw.aui) notebook. (#882) * Fix a bug in py.introspect.getTokens. (#889) * Added Vagrant configuration for Fedora-28. Removed Fedora-23 (#884) * Added wrappers for the wx.WindowIDRef class and added the wx.NewIdRef function. These will make it possible to create reserved Window IDs using the same mechanism which is used when passing wx.ID_ANY to a widget constructor. The object returned by wx.NewIdRef will automatically convert to an int when passing it to a window constructor, and can also be used as the source in a Bind(). (#896) * Fixed issue when sys.prefix is not unicode (Python2) and when its contents are not translatable to utf-8. What is wxPython? ----------------- wxPython is a cross-platform GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a set of Python extension modules that wrap the GUI components of the popular wxWidgets cross platform library, which is written in C++. Supported platforms are Microsoft Windows, Mac OS X and macOS, and Linux or other unix-like systems with GTK2 or GTK3 libraries. In most cases the native widgets are used on each platform to provide a 100% native look and feel for the application. What is wxPython Phoenix? ------------------------- wxPython's Project Phoenix is a new from-the-ground-up implementation of wxPython, created with the intent of making wxPython “better, stronger, faster than he was before.” In other words, this new implementation is focused on improving speed, maintainability and extensibility of wxPython, as well as removing most of the cruft that had accumulated over the long life of Classic wxPython. The project has been in development off and on, mostly behind the scenes, for many years. For the past few years automated snapshot builds have been available for those adventurous enough to try it, and many people eventually started using the snapshots in their projects, even for production releases. While there are still some things on the periphery that need to be completed, the core of the new wxPython extension modules which wrap the wxWidgets code has been stable for a long time now. Due to some things being cleaned up, reorganized, simplified and dehackified wxPython Phoenix is not completely backwards compatible with wxPython Classic. This is intended. In general, however, the API differences tend to be minor and some applications can use Phoenix with slight, or even with no modifications. In some other cases the correct way to do things was also available in Classic and it's only the wrong way that has been removed from Phoenix. For more information there is a Migration Guide document available at: https://docs.wxpython.org/MigrationGuide.html The new wxPython API reference documentation, including all Python-specific additions and customizations, and docs for the wx.lib package, is located at: https://docs.wxpython.org/ -- Robin Dunn Software Craftsman http://wxPython.org
