EuroPython 2017 Keynote: Katharine Jarmul
by Alexander Hendorf 18 May '17

18 May '17

We are pleased to announce our next keynote speaker for EuroPython 2017: * Katharine Jarmul * About Katharine Jarmul ------------------------ Katharine Jarmul is a pythonista and founder of Kjamistan, a data consulting company in Berlin, Germany. She’s been using Python since 2008 to solve and create problems. She helped form the first PyLadies chapter in Los Angeles in 2010, and co-authored an O'Reilly book along with several video courses on Python and data. She enjoys following the latest developments in machine learning, natural language processing and workflow automation infrastructure and is generally chatty and crabby on Twitter, where you can keep up with her latest shenanigans (@kjam). The Keynote: If Ethics is not None ------------------------------------- The history of computing, as it’s often covered in textbooks or talks, remains primarily focused on a series of hardware advancements, architectures, operating systems and software. In this talk, we will instead explore the history of ethics in computing, touching on the early days of computers in warfare and science, leading up to ethical issues today such as Artificial Intelligence and privacy regulation.

attrs 17.1.0
by Hynek Schlawack 16 May '17

16 May '17

Hi everyone, fresh for PyCon US 2017, the attrs team is relieved to present you the much-delayed attrs 17.1.0! Full changes: http://www.attrs.org/en/stable/changelog.html *** First the bad news: until 17.1.0, attrs’ logic regarding when to create a __hash__ method was in conflict with Python’s specification. If you use instances as dict keys or put them into sets, you have to either make them frozen explicitly by passing `frozen=True` or implicitly by pinky-swearing to not mutate them and force the creation of __hash__ using `hash=True`. *Please* double check before upgrading! We’re honestly sorry but didn’t see any better way to handle this. But mind you: hashing mutable objects is a bug so the breakage you’ll encounter may very well be the surfacing of latent, sneaky bugs. *** Now the good news! This release took very long (we promise improvement!) which led to the accumulation of a lot of great new features. A few highlights: # Decorators for validators >>> @attr.s ... class C(object): ... x = attr.ib() ... @x.validator ... def check(self, attribute, value): ... if value > 42: ... raise ValueError("y must be smaller or equal to 42") >>> C(42) C(x=42) >>> C(43) Traceback (most recent call last): ... ValueError: x must be smaller or equal to 42 # Decorators for defaults & self in factories One of the most requested features: you can base the default of an attribute on a preceding attribute: >>> @attr.s ... class C(object): ... x = attr.ib(default=1) ... y = attr.ib(default=attr.Factory(lambda self: self.x + 1, takes_self=True)) ... z = attr.ib() ... @z.default ... def name_does_not_matter(self): ... return self.x + 1 >>> C() C(x=1, y=2, z=3) # New Validators: in_() & and_() in_() allows to check whether a value is part of an enum or any container: >>> import enum >>> class State(enum.Enum): ... ON = "on" ... OFF = "off" >>> @attr.s ... class C(object): ... state = attr.ib(validator=attr.validators.in_(State)) ... val = attr.ib(validator=attr.validators.in_([1, 2, 3])) >>> C(State.ON, 1) C(state=<State.ON: 'on'>, val=1) >>> C("on", 1) Traceback (most recent call last): ... ValueError: 'state' must be in <enum 'State'> (got 'on') >>> C(State.ON, 4) Traceback (most recent call last): ... ValueError: 'val' must be in [1, 2, 3] (got 4) and_() allows you to compose multiple validators to one. As syntactic sugar, you can also just pass a list to `validator=`. Therefore the following lines are equivalent: x = attr.ib(validator=attr.validators.and_(v1, v2, v3)) x = attr.ib(validator=[v1, v2, v3]) For the attrs team Hynek

aiosmtpd 1.0
by Barry Warsaw 15 May '17

15 May '17

Hi! On behalf of all the developers, I'm very happy to announce the release of aiosmtpd 1.0 final. aiosmtpd is a re-implementation of the stdlib smtpd.py module on top of the asyncio framework. It is compliant with the relevant RFCs (5321, 2033, etc.) and supports both SMTP (Simple Mail Transport Protocol) and LMTP (Local Mail Transport Protocol) out of the box. It provides for running the server both from Python and the command line, and it is extensible both by subclassing and by implementing your own "event handlers". aiosmtpd is compatible with Python 3.4 (though we will probably drop that soon so we can use the new async/await keywords) through 3.6. Project home: https://github.com/aio-libs/aiosmtpd Report bugs at: https://github.com/aio-libs/aiosmtpd/issues Git clone: https://github.com/aio-libs/aiosmtpd.git Documentation: http://aiosmtpd.readthedocs.io/ StackOverflow: https://stackoverflow.com/questions/tagged/aiosmtpd Enjoy, and I hope to see you at my aiosmtpd talk at Pycon 2017, 2:30pm on Sunday May 21st. https://us.pycon.org/2017/schedule/presentation/147/ Cheers, -Barry

[ann] sphinxcontrib-trio: make sphinx better at documenting functions/methods, esp. for async/await code
by Nathaniel Smith 12 May '17

12 May '17

Hi all, I just released a new package, sphinxcontrib-trio: https://sphinxcontrib-trio.readthedocs.io/ It makes it easier to document many kinds of functions/methods in sphinx, including async functions, abstract methods, generators, etc. I originally wrote it for the trio [1] project, hence the name, but don't let that put you off -- there's nothing about it that's specific to trio, or even to async/await (except that projects that use async/await *really need* an extension like this). Really I think this extension ought to be a standard feature of sphinx. But in the mean time, it's pretty handy. -n [1] https://trio.readthedocs.io -- Nathaniel J. Smith -- https://vorpus.org

NumPy v1.13.0rc1 released.
by Charles R Harris 11 May '17

11 May '17

Hi All, I'm please to announce the NumPy 1.13.0rc1 release. This release supports Python 2.7 and 3.4-3.6 and contains many new features. It is one of the most ambitious releases in the last several years. Some of the highlights and new functions are *Highlights* - Operations like ``a + b + c`` will reuse temporaries on some platforms, resulting in less memory use and faster execution. - Inplace operations check if inputs overlap outputs and create temporaries to avoid problems. - New __array_ufunc__ attribute provides improved ability for classes to override default ufunc behavior. - New np.block function for creating blocked arrays. *New functions* - New ``np.positive`` ufunc. - New ``np.divmod`` ufunc provides more efficient divmod. - New ``np.isnat`` ufunc tests for NaT special values. - New ``np.heaviside`` ufunc computes the Heaviside function. - New ``np.isin`` function, improves on ``in1d``. - New ``np.block`` function for creating blocked arrays. - New ``PyArray_MapIterArrayCopyIfOverlap`` added to NumPy C-API. Wheels for the pre-release are available on PyPI. Source tarballs, zipfiles, release notes, and the Changelog are available on github <https://github.com/numpy/numpy/releases/tag/v1.13.0rc1>. A total of 100 people contributed to this release. People with a "+" by their names contributed a patch for the first time. - A.
