by Pierre Denis 25 Mar '19

25 Mar '19

Lea 3.1.0 final is now released! ---> http://pypi.org/project/lea/3.1.0 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, PP, gambling, education, ... LGPL - Python 2.6+ / Python 3 supported What's new in Lea 3.1.0? ------------------------ The present version essentially consolidates the previous one (3.0.1), adding just few new features. The main changes are: - new switch_func method, for defining CPT by a function (far less memory-consuming for models like noisy-or, noisy-max) - improvements on Markov chain functions, including calculation of absorbing MC - optimization of lea.max_of, lea.min_of functions - bug fixes for symbolic calculation (in particular for Python 2.7) - numerous addings/improvements on wiki tutorials and documentation, especially on Lea API Many thanks... -------------- ... to Paul Moore, Jens Finkhaeuser and Rasmus Bonnevie who provided proposals, contributions, feedbacks that gave the impetus for the present version. To learn more... ---------------- Lea 3 on PyPI -> http://pypi.org/project/lea/3.1.0 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 this Universe less hazardous, Pierre Denis

by Oleg Broytman 19 Mar '19

19 Mar '19

Hello! I'm pleased to announce version 3.2.1, the first bugfix release of branch 3.2 of CheetahTemplate3. What's new in CheetahTemplate3 ============================== Contributor for this release is Nicola Soranzo. Minor features: - Changed LoadTemplate.loadTemplate{Module,Class}: the loaded module's __name__ set to just the file name. - Use imp for Python 2, importlib for Python 3. Bug fixes: - Fix a bug in LoadTemplate.loadTemplate{Module,Class}: raise ImportError if the template was not found. CI: - At Travis deploy wheels for macOS. - At AppVeyor deploy wheels directly to PyPI. What is CheetahTemplate3 ======================== Cheetah3 is a free and open source template engine. It's a fork of the original CheetahTemplate library. Python 2.7 or 3.4+ is required. Where is CheetahTemplate3 ========================= Site: http://cheetahtemplate.org/ Development: https://github.com/CheetahTemplate3 Download: https://pypi.org/project/Cheetah3/3.2.1/ News and changes: http://cheetahtemplate.org/news.html StackOverflow: https://stackoverflow.com/questions/tagged/cheetah Example ======= Below is a simple example of some Cheetah code, as you can see it's practically Python. You can import, inherit and define methods just like in a regular Python module, since that's what your Cheetah templates are compiled to :) :: #from Cheetah.Template import Template #extends Template #set $people = [{'name' : 'Tom', 'mood' : 'Happy'}, {'name' : 'Dick', 'mood' : 'Sad'}, {'name' : 'Harry', 'mood' : 'Hairy'}] <strong>How are you feeling?</strong> <ul> #for $person in $people <li> $person['name'] is $person['mood'] </li> #end for </ul> Oleg. -- Oleg Broytman https://phdru.name/ phd(a)phdru.name Programmers don't die, they just GOSUB without RETURN.

Python 3.4.10 is now available
by Larry Hastings 18 Mar '19

18 Mar '19

On behalf of the Python development community, I'm proud--if slightly sad--to announce the availability of Python 3.4.10. Python 3.4.10 was released in "security fixes only" mode. It only contains security fixes, not conventional bug fixes, and it is a source-only release. Python 3.4.10 is the final release in the Python 3.4 series. As of this release, the 3.4 branch has been retired, no further changes to 3.4 will be accepted, and no new releases will be made. This is standard Python policy; Python releases get five years of support and are then retired. If you're still using Python 3.4, you should consider upgrading to the current version--3.7.2 as of this writing. Newer versions of Python have many new features, performance improvements, and bug fixes, which should all serve to enhance your Python programming experience. We in the Python core development community thank you for your interest in 3.4, and we wish you all the best! You can find Python 3.4.10 here: https://www.python.org/downloads/release/python-3410/ One I completely finish the Python 3.4.10 release process, I will retire as Python 3.4 Release Manager. I'll still be Python 3.5 Release Manager for another eighteen months or so. Python 3.4 is OVER! https://www.youtube.com/watch?v=YlGqN3AKOsA //arry/

Hello all, I'm glad to announce the release of psutil 5.6.1: https://github.com/giampaolo/psutil About ===== psutil (process and system utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports Linux, Windows, macOS, Sun Solaris, FreeBSD, OpenBSD, NetBSD and AIX, both 32-bit and 64-bit architectures. Supported Python versions are 2.6, 2.7 and 3.4+. PyPy is also known to work. What's new ========== 2019-03-11 **Bug fixes** - #1329: [AIX] psutil doesn't compile on AIX 6.1. (patch by Arnon Yaari) - #1448: [Windows] crash on import due to rtlIpv6AddressToStringA not available on Wine. - #1451: [Windows] Process.memory_full_info() segfaults. NtQueryVirtualMemory is now used instead of QueryWorkingSet to calculate USS memory.
