[baseline 0.2.1] Easy String Baseline
by Dan Gass 30 Mar '20

30 Mar '20

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 30 Jun '19

30 Jun '19

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 30 Jun '19

30 Jun '19

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.

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).
