ftputil 3.3 released
by Stefan Schwarzer 25 Dec '15

25 Dec '15

ftputil 3.3 is now available from http://ftputil.sschwarzer.net/download and at the Python Package Index (PyPI). Changes since version 3.2 ------------------------- - Added `rest` argument to `FTPHost.open` for recovery after interrupted transfers [1]. - Fixed handling of non-ASCII directory and file names under Python 2 [2]. Under Python 3, the directory and file names could already contain any characters from the ISO 5589-1 (latin-1) character set. Under Python 2, non-ASCII characters (even out of the latin-1 character set) resulted in a `UnicodeEncodeError`. Now Python 2 behaves like Python 3, supporting all latin-1 characters. Note that for interoperability between servers and clients it's still usually safest to use only ASCII characters for directory and file names. - Changed `FTPHost.makedirs` for better handling of "virtual directories" [3, 4]. Thanks to Roger Demetrescu for the implementation. - Small improvements [5, 6, 7] Upgrading is recommended. Note that ftputil 3.0 broke backward compatibility with ftputil 2.8 and before. The differences are described here: http://ftputil.sschwarzer.net/trac/wiki/WhatsNewInFtputil3.0 What is ftputil? ---------------- ftputil is a high-level FTP client library for the Python programming language. ftputil implements a virtual file system for accessing FTP servers, that is, it can generate file-like objects for remote files. The library supports many functions similar to those in the os, os.path and shutil modules. ftputil has convenience functions for conditional uploads and downloads, and handles FTP clients and servers in different timezones. See the documentation for details: http://ftputil.sschwarzer.net/trac/wiki/Documentation License ------- ftputil is open source software, released under the revised BSD license (see http://opensource.org/licenses/BSD-3-Clause ).

ANN: Lea 2.2.0-beta.4
by Pierre Denis 22 Dec '15

22 Dec '15

Hi all! For those of you interested in probabilities and probabilistic programming, I’m happy to announce that Lea 2.2.0 is now under beta-test. What is Lea? ------------ Lea is a Python package aiming at working with discrete probability distributions in an intuitive way. It allows you to model a broad range of random phenomenons, like dice throwing, coin tossing, gambling, weather, etc. It offers several high-level modelling features for probabilistic programming, including bayesian inference and Markov chains. Lea is open-source (LGPL) and runs on Python 2 or 3. See project page below for more information (installation, tutorials, examples, etc). What’s new? ----------- Compared to latest version (2.1.2), many things have been made in 2.2.0 to improve ease-of-use and overall performance, without breaking backward compatibility. Maybe one of the most notable feature is that you can now get individual probability very easily, as a fraction or float, thanks to the new 'P' and 'Pf' functions, e.g. >>> P(dice <= 5) 5/18 >>> Pf(dice <= 5) 0.2777777777777778 >>> P(rain.given(grassWet)) 891/2491 >>> Pf(rain.given(grassWet)) 0.3576876756322762 New methods allow you to read a CSV file or Pandas dataframe, then build the corresponding joint probability distribution. Also, Monte-Carlo sampling estimation is now available, should Lea’s default exact evaluation is intractable. Most of the new features are documented in a new tutorial on Lea's wiki (https://bitbucket.org/piedenis/lea/wiki/LeaPyTutorial3). The latest version, Lea 2.2.0-beta.4, is fairly stable (no known bug) so you can start to use it and report any problem or dislike, if any. Lea project page ---------------- https://bitbucket.org/piedenis/lea Download Lea (PyPI) ------------------- http://pypi.python.org/pypi/lea With the hope that Lea can make the Force less uncertain, Pierre Denis

[RELEASED] Python 3.4.4 is now available
by Larry Hastings 21 Dec '15

21 Dec '15

On behalf of the Python development community and the Python 3.4 release team, I'm pleased to announce the availability of Python 3.4.4. Python 3.4.4 is the last version of Python 3.4.4 with binary installers, and the end of "bugfix" support. After this release, Python 3.4.4 moves into "security fixes only" mode, and future releases will be source-code-only. You can see what's changed in Python 3.4.4 (as compared to previous versions of 3.4) here: https://docs.python.org/3.4/whatsnew/changelog.html#python-3-4-4 And you can download Python 3.4.4 here: https://www.python.org/downloads/release/python-344/ Windows and Mac users: please read the important platform-specific "Notes on this release" section near the end of that page. One final note. 3.4.4 final marks the end of an era: it contains the last Windows installers that will be built by Martin von Loewis. Martin has been the Windows release "Platform Expert" since the Python 2.4 release cycle started more than twelve years ago--in other words, for more than half of Python's entire existence! On behalf of the Python community, and particularly on behalf of the Python release managers, I'd like to thank Martin for his years of service to the community, and for the care and professionalism he brought to his role. It was a pleasure working with him, and we wish him the very best in his future projects. We hope you enjoy Python 3.4.4! Happy holidays, //arry/

PyMailGUI: now with SSL and Gmail support
by Mark Lutz 16 Dec '15

16 Dec '15

A minor but crucial update to a system announced here a few days ago: the PyMailGUI POP/SMTP email client now supports SSL modes on servers. SSL is generally recommended by many servers, and required by some (e.g., Gmail). Also in this update: a new config file for using the program with Gmail accounts; a new Linux screenshot; a minor patch to a patch for older 3.X libs; and additional book code imported only on rarely-used PyEdit actions. The update: http://learning-python.com/pymailgui/Readme-PyMailGUI.html#SSL The scene on Linux: http://learning-python.com/pymailgui/screenshots/linux-screenshot-pymailgui… The original announcement: > There is a new standalone release of PyMailGUI - a POP/SMTP email client > which is a major example in a large Python book (shameless plug omitted). > This release's code is identical to that in the book, but has a different > launcher and a self-contained package structure for standalone use. > > PyMailGUI is a bit limited because it was written for use as a teaching > tool in a book. On the other hand, it does threading, MIME attachments, > Unicode, and more, and is useful enough to have served as its author's > primary email tool for over a decade. It may also reduce the probability > of your email being read by a giant evil company without your consent. > > Screenshot: > http://learning-python.com/pymailgui/screenshots/main-standalone.png > Docs: > http://learning-python.com/pymailgui/Readme-PyMailGUI.html > Code: > http://learning-python.com/pymailgui/ > Fetch: > http://learning-python.com/downloads/ Cheers again, --M.

ANN: Astropy v1.1 released
by Thomas Robitaille 14 Dec '15

14 Dec '15

Dear colleagues, We are very happy to announce the v1.1 release of the Astropy package, a core Python package for Astronomy: http://www.astropy.org Astropy is a community-driven Python package intended to contain much of the core functionality and common tools needed for astronomy and astrophysics. New and improved major functionality in this release includes: * New functions to automatically determine histogram bins, including the Bayesian blocks algorithm * A new interface to transform between Table objects and pandas DataFrame objects * Support for table indexing * Support for supergalactic and ecliptic coordinates * A new .info attribute to get summary information about tables and columns * A new show_in_notebook() method to show a table in Jupyter/IPython notebooks with additional interactivity features * Support for new units, including logarithmic units such as magnitudes, dex, and decibels * Support for the Planck 2015 cosmology and significant performance improvements in the cosmology sub-package In addition, hundreds of smaller improvements and fixes have been made. An overview of the changes is provided at: http://docs.astropy.org/en/stable/whatsnew/1.1.html Instructions for installing Astropy are provided on our website, and extensive documentation can be found at: http://docs.astropy.org If you make use of the Anaconda Python Distribution, you can update to Astropy v1.1 with: conda update astropy If you normally use pip, you can upgrade with: pip install astropy --upgrade Please report any issues, or request new features via our GitHub repository: https://github.com/astropy/astropy/issues Over 160 developers have contributed code to Astropy so far, and you can find out more about the team behind Astropy here: http://www.astropy.org/team.html As a reminder, Astropy v1.0 (our long term support release) will continue to be supported with bug fixes until Feb 19th 2017, so if you need to use Astropy in a very stable environment, you may want to consider staying on the v1.0.x set of releases rather than upgrading to v1.1. If you use Astropy directly for your work, or as a dependency to another package, please remember to include the following acknowledgment at the end of papers: """ This research made use of Astropy, a community-developed core Python package for Astronomy (Astropy Collaboration, 2013). """ where (Astropy Collaboration, 2013) is a reference to the Astropy paper: http://dx.doi.org/10.1051/0004-6361/201322068 Please feel free to forward this announcement to anyone you think might be interested in this release! Thomas Robitaille, Erik Tollerud, and Perry Greenfield on behalf of The Astropy Collaboration
