[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)

NumPy 1.17.0rc1 released
by Charles R Harris June 30, 2019

June 30, 2019

Hi All, On behalf of the NumPy team I am pleased to announce the release of NumPy 1.17.0rc1. The 1.17 release contains a number of new features that should substantially improve its performance and usefulness. The Python versions supported are 3.5-3.7, note that Python 2.7 has been dropped. Python 3.8b1 should work with the released source packages, but there are no guarantees about future releases. Highlights of this release are: - A new extensible random module along with four selectable random numbe5 generators and improved seeding designed for use in parallel processes has been added. The currently available bit generators are MT19937, PCG64, Philox, and SFC64. - NumPy's FFT implementation was changed from fftpack to pocketfft, resulting in faster, more accurate transforms and better handling of datasets of prime length. - New radix sort and timsort sorting methods. It is currently not possible to choose which will be used, but they are hardwired to the datatype and used when either ``stable`` or ``mergesort`` is passed as the method. - Overriding numpy functions is now possible by default Downstream developers should use Cython >= 0.29.10 for Python 3.8 support and OpenBLAS >= 3.7 (not currently out) to avoid problems on the Skylake architecture. The NumPy wheels on PyPI are built from the OpenBLAS development branch in order to avoid those problems. Wheels for this release can be downloaded from PyPI <https://pypi.org/project/numpy/1.17.0rc1/>, source archives and release notes are available from Github <https://github.com/numpy/numpy/releases/tag/v1.17.0rc1>. *Contributors* A total of 142 people contributed to this release.

EuroPython 2019: Introducing MongoDB
by M.-A. Lemburg June 30, 2019

June 30, 2019

We are very pleased to have MongoDB as Keystone Sponsor for EuroPython 2019. You can visit them at the most central booth in our exhibit area on the second floor in the Congress Center Basel (CCB), and take the opportunity to chat with their staff and learn more about the MongoDB eco-system. Please find below a hosted blog post from MongoDB. Enjoy, – EuroPython 2019 Team https://ep2019.europython.eu/ https://www.europython-society.org/ MongoDB ❤ Python ---------------- MongoDB is the leading modern, general-purpose database platform, designed to unleash the power of software and data for developers and the applications they build. We have architected our database to cater to the needs of modern-day applications from the ground-up with built-in support for high availability through sophisticated replication with self-healing recovery and horizontal scalability through native sharding. MongoDB Atlas is our fully-automated database-as-a-service offering, engineered and run by the same team that builds the database. At MongoDB, it is our mission to make data ridiculously easy to work with and we love, love, LOVE Python because it helps us do exactly that. To bring the power of MongoDB to the Python ecosystem, we’ve developed PyMongo - the Python driver for MongoDB. With over 3 million downloads per month, PyMongo is one of our most popular drivers. Our Driver team also maintains Motor - an asynchronous Python driver for MongoDB and PyMODM - our object-document mapper. While Python is an important and popular tool for our users, it is also an integral part of developer workflows across our engineering teams. Our Documentation team, for instance, maintains the Giza library which is used to render the entire official MongoDB documentation. Our Education team builds MongoDB University with Django and uses PyMODM and MongoDB Atlas to store application data. The University site has over 1 million registered users and over 100,000 active users per month–all powered by MongoDB. Python is also an integral part of our CI/CD process used to test our core database and all drivers. Join us at our workshop where we will teach you how to harness the power of MongoDB Atlas to build a highly-available CRUD application using Flask and PyMongo. You will learn more about MongoDB’s document data model, how we ensure high-availability and best practices for building applications using MongoDB. We will also showcase how to build the same application in MongoDB Stitch - our serverless platform. Bring your laptops! MongoDB is proud to support the Python community. In the past, we have sponsored conferences such as PyCon and PyGotham, and also hosted meetups such as PyLadies. Drop by our booth (#10) to say ‘hi’ to our awesome team and to learn more about Python at MongoDB! You can also join the conversation with other MongoDB and Python community members in our Community Slack Workspace. Register at http://launchpass.com/mongo-d or login at http://mongo-db.slack.com.

EuroPython 2019: Beginners’ Day Workshop
by M.-A. Lemburg June 27, 2019

June 27, 2019

If you're new to Python, you should come to our friendly, welcoming and helpful Beginners' Day Workshop. We cater to new Pythonistas of all levels: from absolute beginners through to experienced programmers encountering Python for the first time. * https://ep2019.europython.eu/events/beginners-day/ * What is Beginners' Day ? ------------------------ Beginners' day welcomes and supports folks who are new to Python programming. It takes place on Tuesday 9th July, from 9:30 - 16:00 at the workshop venue, FHNW Campus Muttenz. Just in time to get you ready for all the talks which follow on Wednesday, Thursday and Friday ! It's also a great place to make friends with fellow attendees and figure out how to get the most out of EuroPython. Bring your laptop, because this will be a hands-on session! The day will start with workshops to give you the chance to try out Python in lots of different situations: making a game, creating a website, programming embedded devices or telling stories with data (in a Jupyter notebook). Later in the day you'll have an opportunity to further explore those aspects of Python which appeal to you with the support of a team of experienced and helpful mentors. We'll end the day with a question and answer session about Python, EuroPython and the wider Python ecosystem. The emphasis will be in creating a fun, supportive and useful path into the Python programming language and its community. Sign up for Beginners' Day -------------------------- You will need a conference pass to attend, but otherwise, it's free, so if you're thinking of coming to the conference, but you're new to Python or programming, this could be the session for you: https://ep2019.europython.eu/registration/buy-tickets/ The session will be presented in English (although our mentors will typically speak a few other languages as well). If you'd like to come, please do register in advance for this session, so that we know how to plan to make it the best yet. We need to know the numbers for planing the workshop. Sign up for Beginners' Day here: https://docs.google.com/forms/d/e/1FAIpQLScBSJ8y--ROBI7HDQ01H1Cn9RI9amC9mRo… Call for Mentors ---------------- The workshop is being organised by experienced Python programmer and educator, Nicholas H.Tollervey. Already know Python? Do you value working in an open, inclusive and collaborative way? Want to develop your mentorship skills? Fantastic!

It's rewarding, fun and a great way to give back to the community. We'd especially love to hear from you if you can add an extra language to help non-English speakers feel comfortable asking questions, or if you've never mentored before and want to try to share your knowledge for the first time. This is a supportive environment for both beginner programmers AND beginner mentors. :-) Please sign up as a mentor on our mentor registration form: https://docs.google.com/forms/d/e/1FAIpQLSdkphUVi_vplS7yvxI432R03BJPCapv-K2… Dates and Venues ---------------- EuroPython will be held from July 8-14 2019 in Basel, Switzerland, at the Congress Center Basel (CCB) for the main conference days (Wed-Fri) and the FHNW Muttenz for the workshops/trainings/sprints days (Mon-Tue, Sat-Sun).

EuroPython 2019: Warning - Spoiler alert!
by M.-A. Lemburg June 14, 2019

June 14, 2019

Usually, we try to have something as surprise for our attendees every year. However, for this year’s conference, we have decided to give our attendees something to play with and this needs a little more preparation than a bottle or a beach towel. Drum roll… crowd screaming… and here it is: we’re please to present the... EuroPython 2019 PewPew Game Console ----------------------------------- * https://ep2019.europython.eu/events/pewpew-workshops/ * The device was created and designed by Radomir Dopieralski, a long time EuroPython regular and enthusiastic Python device and robotics builder. The PewPew is a simplified game console, programmable with CircuitPython, a variant of MicroPython. It comes with a 64 LED display and a set of small buttons to drive the console. We will have one device per attendee with training or conference ticket and plan to give them out together with the badges. Free Workshops -------------- To teach you how to program the consoles and help with any questions you may have, we have arranged a special workshop room on the training days Monday and Tuesday, where Radomir and his team will run workshops focusing on the PewPew. You will learn how to write small programs and games. Our hope is that you will take this knowledge home and spread the word about how much fun Python is – especially for younger users. The workshops are free for EuroPython conference or training ticket holders, but please see our notes on catering on the training days. Help us run the workshops ------------------------- Since Radomir needs help with running the workshops, we are reaching out to you with this blog post. If you are interested in embedded Python, hardware hacking, game development and similar topics, we invite you to come help us running those workshops. This is a great opportunity to meet with Python developers and learn together, and we’re sure you will have great fun while helping other attendees. Whether it’s just lending a hand getting things working, or running a whole workshop – it’s up to you, either way we will greatly appreciate your help. Please sign up using our mentor form. Many thanks ! https://docs.google.com/forms/d/e/1FAIpQLSefU0VMGA7QVO6DgO_9faHQ_Z4XcsfpRZ2… More information will be available on the PewPew workshop page: https://ep2019.europython.eu/events/pewpew-workshops/ Dates and Venues ---------------- EuroPython will be held from July 8-14 2019 in Basel, Switzerland, at the Congress Center Basel (CCB) for the main conference days (Wed-Fri) and the FHNW Muttenz for the workshops/trainings/sprints days (Mon-Tue, Sat-Sun).

ANN: czml3 0.1.0 released 🌍
by Juan Luis Cano Rodríguez June 13, 2019

June 13, 2019

Hi all, It fills us with astronomical joy to announce the release of czml3 0.1.0! 🌍 czml3 is a Python (3.6+) library to write CZML. Copying from the CZML Guide: > CZML is a JSON format for describing a time-dynamic graphical scene, > primarily for display in a web browser running Cesium. It describes > lines, points, billboards, models, and other graphical primitives, and > specifies how they change with time. While Cesium has a rich > client-side API, CZML allows it to be data-driven so that a generic > Cesium viewer can display a rich scene without the need for any custom > code. In many ways, the relationship between Cesium and CZML is > similar to the relationship between Google Earth and KML. czml3 aims to be useful for interactive use: >>> from czml3 import Packet >>> Packet() { "id": "adae4d3a-7087-4fda-a70b-d18a262a890e" } >>> packet0 = Packet(id="Facility/AGI", name="AGI") >>> packet0 { "id": "Facility/AGI", "name": "AGI" } >>> packet0.dumps() '{"id": "Facility/AGI", "name": "AGI"}' This first release is far from complete, but already has the core functionality and many basic properties that allow users to visualize Earth orbits. You can install it with pip: pip install czml3 And check out the repository on GitHub, which contains a more detailed README, tests (>99 % coverage) and the issue tracker: https://github.com/poliastro/czml3 If you have any questions or want to contribute, join our chat! https://chat.openastronomy.org/#/room/#poliastro-czml:matrix.org czml3 is similar in intent to czml, a Python library written by Christian Ledermann. czml3 is implemented from scratch and tries to be easier to use on an interactive interpreter, and (for the moment) focuses only on writing. Per Python ad astra!

ANN: Astropy v3.2 released
by Erik Tollerud June 13, 2019

June 13, 2019

Dear colleagues, We are very happy to announce the v3.2 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. It is part of the Astropy Project, which aims to foster an ecosystem of interoperable astronomy packages for Python. New and improved major functionality in this release includes: * New Sub-package for Time Series * New SI/CODATA 2018 Constants * Additions and changes to Ecliptic Transformations * Table performance improvements and change in metadata handling * Table I/O integration of pandas I/O functions for ASCII tables * Improved help on Table read() and write() methods 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/3.2.html Note that the Astropy 3.x series only supports Python 3. Python 2 users can continue to use the 2.x (LTS) series (but without new features). 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 v3.2 with: conda update astropy Whereas if you usually use pip, you can do: pip install astropy --upgrade Please report any issues, or request new features via our GitHub repository: https://github.com/astropy/astropy/issues Over 300 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 v2.0 (our long term support release) will continue to be supported with bug fixes (but no new features) until the end of 2019, so if you need to use Astropy in a very stable environment, you may want to consider staying on the v2.0.x set of releases (for which we have recently released v2.0.13). If you use Astropy directly for your work, or as a dependency to another package, please remember to acknowledgment it by citing the appropriate Astropy paper. For the most up-to-date suggestions, see the acknowledgement page, but as of this release the recommendation is: This research made use of Astropy, a community-developed core Python package for Astronomy (Astropy Collaboration, 2018). where (Astropy Collaboration, 2018) is a reference to https://doi.org/10.3847/1538-3881/aabc4f Special thanks to the coordinator for this release: Brigitta Sipocz. We hope that you enjoy using Astropy as much as we enjoyed developing it! Erik Tollerud, Tom Robitaille, Kelle Cruz, and Tom Aldcroft on behalf of The Astropy Collaboration

[SECURITY] Twisted 19.2.1 Release Announcement
by Amber Brown June 6, 2019

June 6, 2019

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 19.2.1! This is a security release, and contains the following changes: - All HTTP clients in twisted.web.client now raise a ValueError when called with a method and/or URL that contain invalid characters. This mitigates CVE-2019-12387. Thanks to Alex Brasetvik for reporting this vulnerability. It is recommended you update to this release as soon as is practical. Additional mitigation may be required if Twisted is not your only HTTP client library: - This bug is present in all current versions of urllib2 in CPython. More information can be found on the Python bug tracker: https://bugs.python.org/issue30458 - This bug was present in urllib3 up until version 1.24.3. More information can be found on the urllib3 bug tracker: https://github.com/urllib3/urllib3/issues/1553 You can find the downloads at <https://pypi.python.org/pypi/Twisted> (or alternatively <http://twistedmatrix.com/trac/wiki/Downloads>). The NEWS file is also available at <https://github.com/twisted/twisted/blob/twisted-19.2.1/NEWS.rst>. Twisted Regards, Amber Brown (HawkOwl)

[RELEASE] Python 3.8.0b1 is now available for testing
by Łukasz Langa June 4, 2019

June 4, 2019

The time has come for Python 3.8.0b1: https://www.python.org/downloads/release/python-380b1/ <https://www.python.org/downloads/release/python-380b1/> This release is the first of four planned beta release previews. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. The next pre-release of Python 3.8 will be 3.8.0b2, currently scheduled for 2019-07-01. Call to action We strongly encourage maintainers of third-party Python projects to test with 3.8 during the beta phase and report issues found to the Python bug tracker <https://bugs.python.org/> as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2019-09-30). Our goal is have no ABI changes after beta 3 and no code changes after 3.8.0rc1, the release candidate. To achieve that, it will be extremely important to get as much exposure for 3.8 as possible during the beta phase. Please keep in mind that this is a preview release and its use is not recommended for production environments. A new challenger has appeared! With the release of Python 3.8.0b1, development started on Python 3.9. The “master” branch in the cpython repository now tracks development of 3.9 while Python 3.8 received its own branch, called simply “3.8”. Acknowledgments As you might expect, creating new branches triggers a lot of changes in configuration for all sorts of tooling that we’re using. Additionally, the inevitable deadline for new features caused a flurry of activity that tested the buildbots to the max. The revert hammer got used more than once. I would not be able to make this release available alone. Many thanks to the fearless duo of Pablo Galindo Salgado and Victor Stinner for spending tens of hours during the past week working on getting the buildbots green for release. Seriously, that took a lot of effort. We are all so lucky to have you both. Thanks to Andrew Svetlov for his swift fixes to asyncio and to Yury Selivanov for code reviews, even when jetlagged. Thanks to Julien Palard for untangling the documentation configs. Thank you to Zachary Ware for help with buildbot and CI configuration. Thanks to Mariatta for helping with the bots. Thank you to Steve Dower for delivering the Windows installers. Most importantly though, huge thanks to Ned Deily who not only helped me understand the scope of this special release but also did some of the grunt work involved. Last but not least, thanks to you for making this release more meaty than I expected. There’s plenty of super exciting changes in there. Just take a look at “What’s New <https://docs.python.org/3.8/whatsnew/3.8.html>”! One more thing Hey, fellow Core Developer, Beta 2 is in four weeks. If your important new feature got reverted last minute, or you decided not to merge due to inadequate time, I have a one time offer for you (restrictions apply). If you: find a second core developer champion for your change; and in tandem you finish your change complete with tests and documentation before Beta 2 then I will let it in. I’m asking for a champion because it’s too late now for changes with hasty design or code review. And as I said, restrictions apply. For instance, at this point changes to existing APIs are unlikely to be accepted. Don’t start new work with 3.8 in mind. 3.9 is going to come sooner than you think! - Ł

ANN: Datatest 0.9.4 Released
by Shawn Brown June 3, 2019

June 3, 2019

Datatest provides tools for test driven data-wrangling and data validation. It supports both pytest and unittest style testing. I've been working to get datatest ready for a few pre-PyCon updates. This latest release takes many of the "how-to" solutions and brings them into the core package. * Docs - https://datatest.readthedocs.io/ * PyPI - https://pypi.org/project/datatest/ * Devel - https://github.com/shawnbrown/datatest Upgrade an existing installation to 0.9.4: pip install --upgrade datatest What's New in Datatest 0.9.4: * Added Python 3.8 testing and support. * Added new validate methods (moved from how-to recipes into core module): * Added approx() method to require for approximate numeric equality. * Added fuzzy() method to require strings by approximate match. * Added interval() method to require elements within a given interval. * Added set(), subset(), and superset() methods for explicit membership checking. * Added unique() method to require unique elements. * Added order() method to require elements by relative order. * Changed default sequence validation to check elements by index position rather than checking by relative order. * Added fuzzy-matching allowance to allow strings by approximate match. * Added Predicate class to formalize behavior--also provides inverse-matching with the inversion operator (~). * Added new methods to Query class: * Added unwrap() to remove single-element containers and return their unwrapped contents. * Added starmap() to unpack grouped arguments when applying a function to elements. * Fixed improper use of assert statements with appropriate conditional checks and error behavior. * Added requirement class hierarchy (using BaseRequirement). This gives users a cleaner way to implement custom validation behavior and makes the underlying codebase easier to maintain. * Changed name of ProxyGroup to RepeatingContainer. * Changed "How To" examples to use the new validation methods.
