From anthony.tuininga at gmail.com Mon Mar 5 18:53:46 2018 From: anthony.tuininga at gmail.com (Anthony Tuininga) Date: Mon, 5 Mar 2018 16:53:46 -0700 Subject: cx_Oracle 6.2 Message-ID: What is cx_Oracle? cx_Oracle is a Python extension module that enables access to Oracle Database for Python 3.x and 2.x and conforms to the Python database API 2.0 specifications with a number of enhancements. Where do I get it? https://oracle.github.io/python-cx_Oracle The easiest method to install/upgrade cx_Oracle is via pip as in python -m pip install cx_Oracle --upgrade What's new? This release eliminates the error "DPI-1054: connection cannot be closed when open statements or LOBs exist". It also adds support for creating temporary LOBs and binding LOBs directly to a cursor. You can now also use a connection as a context manager to close the connection at the end of the block by using the new cx_Oracle.__future__ object ( http://cx-oracle.readthedocs.io/en/latest/module.html#cx_Oracle.__future__). This will become the default and only behaviour of using a connection as a context manager unless I hear otherwise! The code was reorganised and simplified in order to streamline further maintenance and a number of bugs were fixed. The full release notes can be read here: http://cx-oracle.readthedocs.io/en/latest/releasenotes.html#version-6-2-march-2018 Please provide any feedback via GitHub issues ( https://github.com/oracle/python-cx_Oracle/issues).

Lemburg) Date: Thu, 8 Mar 2018 13:12:11 +0100 Subject: EuroPython 2018: Hotel tips and general update Message-ID: <612ba7d0-51ca-1b02-1c22-e3db115eed2b@europython.eu> As you may know, the Edinburgh Fringe Festival is starting one week after EuroPython 2018 in Edinburgh. Since this typically attracts many thousands of people and artists, the hotels are filling up quickly in Edinburgh. If you?re planning to attend EuroPython, please book your hotel early. Many booking sites offer free cancellations, so there?s no risk in making reservations now, even if you decide not to come in the end. Room allocation for EuroPython 2018 ----------------------------------- To help with this, we have partnered with the Edinburgh Convention Bureau to set aside a number of hotel rooms which are reserved for EuroPython attendees. These rooms will be held reserved until a few weeks before the conference and are also available with a free cancellation option. The Edinburgh Convention Bureau has setup the following website for booking rooms from this allocation: * EuroPython 2018 Hotel Booking Website * https://cabsedinburgh.eventsair.com/QuickEventWebsitePortal/europython-2018/home-page (run by the Edinburgh Convention Bureau) Update on EuroPython 2018 ------------------------- Meanwhile, we wanted to give you an update of where we are with the conference organization: We are still working on getting everything setup for launching the website, opening ticket sales and the Call for Proposals (CFP). This year the EuroPython Society (EPS) will be running the ticket sales, rather than a local organization and we are facing some challenges related to VAT taxes, which are taking longer to sort out than expected. This is the main reason for the delay you are seeing, but we?re getting there.

Cython is a widely used and production proven optimising static compiler for both the Python programming language and the extended Cython programming language, and one of the pillars of the high-performance Python ecosystem. It provides direct access to C/C++ libraries and data types as a language feature, and makes writing fast native C extensions for Python as easy as Python itself. The major new features in 0.28 include: * Cdef classes can now multiply inherit from ordinary Python classes, as long as (exactly) one base class is an extension type. * The "const" modifier can be applied to memoryview declarations to allow read-only buffers as input. * C code in the docstring of a "cdef extern" block is copied verbatimly into the generated file.

Advanced Scientific Programming in Python ============================================== a Summer School by the G-Node and the University of Camerino https://python.g-node.org Scientists spend more and more time writing, maintaining, and debugging software. While techniques for doing this efficiently have evolved, only few scientists have been trained to use them. As a result, instead of doing their research, they spend far too much time writing deficient code and reinventing the wheel. In this course we will present a selection of advanced programming techniques and best practices which are standard in the industry, but especially tailored to the needs of a programming scientist. Lectures are devised to be interactive and to give the students enough time to acquire direct hands-on experience with the materials. Students will work in pairs throughout the school and will team up to practice the newly learned skills in a real programming project ? an entertaining computer game. We use the Python programming language for the entire course. Python works as a simple programming language for beginners, but more importantly, it also works great in scientific simulations and data analysis. We show how clean language design, ease of extensibility, and the great wealth of open source libraries for scientific computing and data visualization are driving Python to become a standard tool for the programming scientist. This school is targeted at Master or PhD students and Post-docs from all areas of science. Competence in Python or in another language such as Java, C/C++, MATLAB, or Mathematica is absolutely required. Basic knowledge of Python and of a version control system such as git, subversion, mercurial, or bazaar is assumed. Participants without any prior experience with Python and/or git should work through the proposed introductory material before the course. We are striving hard to get a pool of students which is international and gender-balanced: see how far we got in previous years ! Date & Location =============== 3?8 September, 2018. Camerino, Italy. Application =========== You can apply online: https://python.g-node.org/wiki/applications Application deadline: 23:59 UTC, 31 May, 2018. There will be no deadline extension, so be sure to apply on time. Be sure to read the FAQ before applying: https://python.g-node.org/wiki/faq Participation is for free, i.e. no fee is charged!

It will automagically create a new virtualenv (or reuse a previous created one), installing the necessary dependencies, and execute your script inside that virtualenv. You only need to execute the script with fades (instead of Python) and also mark the required dependencies. More details here: http://fades.rtfd.org/ What's new in this release? - Pre-check if everything requested is really available in PyPI before starting to install them - Ignore duplicated dependencies - Several enhancements and fixes in the messages fades shows in verbose mode - Forbid fades misusing: installing it with legacy Python and running it from inside another virtualenv - Lot of project related improvements (not visible directly to final user, though) and some small bug fixes Nicol?s and I want to say a big thank you to the following collaborators that helped to improve and enhance fades in different ways for this version (in alphabetical order): Evan - https://github.com/evandandrea Juan Carlos - https://github.com/juancarlospaco Rotem Yaari - https://github.com/vmalloc To install and enjoy fades... - If you are in Ubuntu or Debian, you can easily install like this (but probably won't get *latest* fades: sudo apt-get install fades - For not latest debian/ubuntu you have a .deb here (with checksum and signature): http://taniquetil.com.ar/fades/fades-latest.deb http://taniquetil.com.ar/fades/fades-latest.deb.sha1 http://taniquetil.com.ar/fades/fades-latest.deb.asc - Install it in Arch is very simple: yaourt -S fades - In any Linux if you have the Snap system: snap install fades - Using pip if you want: pip3 install fades - You can always get the multiplatform tarball and install it in the old fashion way: wget http://taniquetil.com.ar/fades/fades-latest.tar.gz tar -xf fades-latest.tar.gz cd fades-* sudo ./setup.py install Also have the checksum and signature, if interested: http://taniquetil.com.ar/fades/fades-latest.tar.gz.sha1 http://taniquetil.com.ar/fades/fades-latest.tar.gz.asc Help / questions: - You can ask any question or send any recommendation or request in the Telegram group: https://t.me/fadesmagic ...or to the mailing list... http://listas.python.org.ar/mailman/listinfo/fades ...or in the #fades IRC channel (in Freenode). - Also, you can open an issue here (please do if you find any problem!). https://github.com/PyAr/fades/issues/new - The project itself is in https://github.com/PyAr/fades It's very easy to run latest development version: git clone https://github.com/PyAr/fades.git cd fades bin/fades Thanks in advance for your time! -- .

What Changed??=============?This is an enhancement and bug-fix release, and all users are encouraged to upgrade.?See the project website [1] for more information.? Brief summary:? * Subkey information is now collected and returned in a subkey_info? dictionary keyed by the subkey's ID. * GPG2 version is now correctly detected on OS X. * Added expect_passphrase keyword argument for use on GnuPG >= 2.1 when? passing passphrase to gpg via pinentry. * Provided a trust_keys method to allow setting the trust level? for keys. Thanks to William Foster for a suggested implementation. * Made the exception message when the gpg executable is not found contain the? path of the executable that was tried. Thanks to Kostis Anagnostopoulos for? the suggestion. * Made the error message less categorical in the case of a failure with an? unspecified reason, adding some information from gpg error codes when? available.

What Does It Do??================?The gnupg module allows Python programs to make use of the?functionality provided by the Gnu Privacy Guard (abbreviated GPG or?GnuPG). Using this module, Python programs can encrypt and decrypt?data, digitally sign documents and verify digital signatures, manage?(generate, list and delete) encryption keys, using proven Public Key?Infrastructure (PKI) encryption technology based on OpenPGP.? This module is expected to be used with Python versions >= 2.4, as it?makes use of the subprocess module which appeared in that version of?Python. This module is a newer version derived from earlier work by?Andrew Kuchling, Richard Jones and Steve Traugott.? A test suite using unittest is included with the source distribution.? Simple usage:? >>> import gnupg?>>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory')?>>> gpg.list_keys()? [{?...?'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2',?'keyid': '197D5DAC68F1AAB2',?'length': '1024',?'type': 'pub',?'uids': ['', 'Gary Gross (A test user) ']},?{?...?'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A',?'keyid': '0C5FEFA7A921FC4A',?'length': '1024',?...?'uids': ['', 'Danny Davis (A test user) ']}]?>>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A'])?>>> str(encrypted)? '-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9 (GNU/Linux)\n?\nhQIOA/6NHMDTXUwcEAf?.?-----END PGP MESSAGE-----\n'?>>> decrypted = gpg.decrypt(str(encrypted), passphrase='secret')?>>> str(decrypted)? 'Hello, world!'?>>> signed = gpg.sign("Goodbye, world!", passphrase='secret')?>>> verified = gpg.verify(str(signed))?>>> print "Verified" if verified else "Not verified"? 'Verified'? As always, your feedback is most welcome (especially bug reports [3],?patches and suggestions for improvement, or any other points via the?mailing list/discussion group [4]).?

You can find Python 3.7.0b3 here: https://www.python.org/downloads/release/python-370b3/ Among the new major new features in Python 3.7 are: * PEP 538, Coercing the legacy C locale to a UTF-8 based locale * PEP 539, A New C-API for Thread-Local Storage in CPython * PEP 540, UTF-8 mode * PEP 552, Deterministic pyc * PEP 553, Built-in breakpoint() * PEP 557, Data Classes * PEP 560, Core support for typing module and generic types * PEP 562, Module __getattr__ and __dir__ * PEP 563, Postponed Evaluation of Annotations * PEP 564, Time functions with nanosecond resolution * PEP 565, Show DeprecationWarning in __main__ * PEP 567, Context Variables Please see "What?s New In Python 3.7" for more information. Additional documentation for these features and for other changes will be provided during the beta phase. https://docs.python.org/3.7/whatsnew/3.7.html Beta releases are intended to give you the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. We strongly encourage you to test your projects with 3.7 during the beta phase and report issues found to https://bugs.python.org as soon as possible. While the release is 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 (2018-05-21). Our goal is have no ABI changes after beta 3 and no code changes after rc1. To achieve that, it will be extremely important to get as much exposure for 3.7 as possible during the beta phase. Attention macOS users: there is a new installer variant for macOS 10.9+ that includes a built-in version of Tcl/Tk 8.6. This variant is expected to become the default version when 3.7.0 releases. Check it out! We welcome your feedback. As of 3.7.0b3, the legacy 10.6+ installer also includes a built-in Tcl/Tk 8.6. Please keep in mind that this is a preview release and its use is not recommended for production environments. The next planned release of Python 3.7 will be 3.7.0b4, currently scheduled for 2018-04-30. More information about the release schedule can be found here: https://www.python.org/dev/peps/pep-0537/ -- Ned Deily nad at python.org -- [] From p.f.moore at gmail.com Sat Mar 31 07:11:29 2018 From: p.f.moore at gmail.com (Paul Moore) Date: Sat, 31 Mar 2018 12:11:29 +0100 Subject: Beta release of pip version 10 Message-ID: On behalf of the PyPA, I am pleased to announce that a beta release 10.0.0b1 of pip has just been released for testing by the community. We're planning on a final release in 2 weeks' time, over the weekend of 14/15 April. To install pip 10.0.0.b1, you can run python -m pip install --upgrade --pre pip (obviously, you should not do this in a production environment!) We would be grateful for all testing that users could do, to ensure that when pip 10 is released it's as solid as we can make it. Highlights of the new release: * Python 2.6 is no longer supported - if you need pip on Python 2.6, you should stay on pip 9, which is the last version to support Python 2.6. * Support for PEP 518, which allows projects to specify what packages they require in order to build from source. (PEP 518 support is currently limited, with full support coming in future versions - see the documentation for details). * Significant improvements in Unicode handling for non-ASCII locales on Windows. * A new "pip config" command. * The default upgrade strategy has become "only-if-needed" * Many bug fixes and minor improvements. In addition, the previously announced reorganisation of pip's internals has now taken place. Unless you are the author of code that imports the pip module (or a user of such code), this change will not affect you. If you are, please report the issue to the author of the affected code (refer them to https://mail.python.org/pipermail/distutils-sig/2017-October/031642.html for the details of the announcement). Please note that there is a minor issue with the NEWS file for this release - the new features in 10.0.0b1 are reported as being for "9.0.3 (2018-03-31)". If you discover any bugs while testing the new release, please report them at https://github.com/pypa/pip/issues. Thanks to everyone who put so much effort into the new release. Many of the contributions came from community members, whether in the form of code, participation in design discussions, or bug reports. The pip development team is extremely grateful to everyone in the community for their contributions.

This means the site is robust, but we anticipate needing more user testing and changes before it is "production-ready" and can fully replace https://pypi.python.org . We hope to complete the transition before the end of April 2018. We're still working to ensure the new codebase and infrastructure are reliable. So please don't rely on it (yet) unless you can handle the occasional minor outage. But we want you to try the new PyPI, test it, and tell us if you have any problems.
