Vulture 2.4
by Jendrik Seipp May 19, 2022

May 19, 2022

Vulture - Find dead code ======================== Vulture finds unused code in Python programs. This is useful for cleaning up and finding errors in large code bases. If you run Vulture on both your library and test suite you can find untested code. Due to Python's dynamic nature, static code analyzers like Vulture are likely to miss some dead code. Also, code that is only called implicitly may be reported as unused. Nonetheless, Vulture can be a very helpful tool for higher code quality. Download ======== https://github.com/jendrikseipp/vulture http://pypi.python.org/pypi/vulture Features ======== * fast: uses static code analysis * tested: tests itself and has complete test coverage * complements pyflakes and has the same output syntax * sorts unused classes and functions by size with ``--sort-by-size`` * supports Python 3.6+ News ==== * Print absolute filepaths as relative again (as in version 2.1 and before) if they are below the current directory (The-Compiler, #246). * Run tests and add PyPI trove for Python 3.10 (chayim, #266). * Allow using the `del` keyword to mark unused variables (sshishov, #279). Cheers Jendrik

[RELEASE] Python 3.9.13 is now available
by Łukasz Langa May 17, 2022

May 17, 2022

This is the thirteenth maintenance release of Python 3.9. Get it here: Python 3.9.13 <https://www.python.org/downloads/release/python-3913/> According to the release calendar specified in PEP 596 <https://www.python.org/dev/peps/pep-0596/>, Python 3.9.13 is the final regular maintenance release. Starting now, the 3.9 branch will only accept security fixes and releases of those will be made in source-only form until October 2025. This is a milestone moment for me as it means that now both of my release series are security-only. My work as release manager enters its final stage. I’m not crying, you’re crying! 🥲 Compared to the 3.8 series, this last regular bugfix release is still pretty active at 166 commits since 3.9.12. In comparison, version 3.8.10, the final regular bugfix release of Python 3.8, included only 92 commits. However, it’s likely that it was 3.8 that was special here with the governance changes occupying core developers’ minds. For reference, version 3.7.8, the final regular bugfix release of Python 3.7, included 187 commits. In any case, 166 commits is quite a few changes, some of which being pretty important fixes. Take a look at the change log <https://docs.python.org/release/3.9.13/whatsnew/changelog.html> for details. <https://discuss.python.org/t/python-3-9-13-is-now-available/15815#major-new…>Major new features of the 3.9 series, compared to 3.8 Some of the new major new features and changes in Python 3.9 are: PEP 573 <https://www.python.org/dev/peps/pep-0573/>, Module State Access from C Extension Methods PEP 584 <https://www.python.org/dev/peps/pep-0584/>, Union Operators in dict PEP 585 <https://www.python.org/dev/peps/pep-0585/>, Type Hinting Generics In Standard Collections PEP 593 <https://www.python.org/dev/peps/pep-0593/>, Flexible function and variable annotations PEP 602 <https://www.python.org/dev/peps/pep-0602/>, Python adopts a stable annual release cadence PEP 614 <https://www.python.org/dev/peps/pep-0614/>, Relaxing Grammar Restrictions On Decorators PEP 615 <https://www.python.org/dev/peps/pep-0615/>, Support for the IANA Time Zone Database in the Standard Library PEP 616 <https://www.python.org/dev/peps/pep-0616/>, String methods to remove prefixes and suffixes PEP 617 <https://www.python.org/dev/peps/pep-0617/>, New PEG parser for CPython BPO 38379 <https://bugs.python.org/issue38379>, garbage collection does not block on resurrected objects; BPO 38692 <https://bugs.python.org/issue38692>, os.pidfd_open added that allows process management without races and signals; BPO 39926 <https://bugs.python.org/issue39926>, Unicode support updated to version 13.0.0; BPO 1635741 <https://bugs.python.org/issue1635741>, when Python is initialized multiple times in the same process, it does not leak memory anymore; A number of Python builtins (range, tuple, set, frozenset, list, dict) are now sped up using PEP 590 <https://www.python.org/dev/peps/pep-0590> vectorcall; A number of Python modules (_abc, audioop, _bz2, _codecs, _contextvars, _crypt, _functools, _json, _locale, operator, resource, time, _weakref) now use multiphase initialization as defined by PEP 489 <https://www.python.org/dev/peps/pep-0489/>; A number of standard library modules (audioop, ast, grp, _hashlib, pwd, _posixsubprocess, random, select, struct, termios, zlib) are now using the stable ABI defined by PEP 384 <https://www.python.org/dev/peps/pep-0384/>. You can find a more comprehensive list in this release’s “What’s New <https://docs.python.org/release/3.9.13/whatsnew/3.9.html>” document. <https://discuss.python.org/t/python-3-9-13-is-now-available/15815#we-hope-y…>We hope you enjoy Python 3.9!

We did it, team!! After quite a bumpy release process and a bunch of last-time fixes, we have reached **beta 1** and **feature freeze**. What a ride eh? You can get the shiny new release artefacts from here: https://www.python.org/downloads/release/python-3110b1/ ## This is a beta preview of Python 3.11 Python 3.11 is still in development. 3.11.0b1 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. We **strongly encourage** maintainers of third-party Python projects to **test with 3.11** 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 (Monday, 2021-08-02). Our goal is to have no ABI changes after beta 4 and as few code changes as possible after 3.11.0rc1, the first release candidate. To achieve that, it will be **extremely important** to get as much exposure for 3.11 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. # Major new features of the 3.11 series, compared to 3.10 Python 3.11 is still in development. This release, 3.11.0b1 is the **first** of four beta releases. 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. Many new features for Python 3.11 are still being planned and written. Among the new major new features and changes so far: * [PEP 657](https://www.python.org/dev/peps/pep-0657/) -- Include Fine-Grained Error Locations in Tracebacks * [PEP 654](https://www.python.org/dev/peps/pep-0654/) -- Exception Groups and except* * [PEP 673](https://www.python.org/dev/peps/pep-0673/) -- Self Type * [PEP 646](https://www.python.org/dev/peps/pep-0646/)-- Variadic Generics * [PEP 680](https://www.python.org/dev/peps/pep-0680/)-- tomllib: Support for Parsing TOML in the Standard Library * [PEP 675](https://www.python.org/dev/peps/pep-0675/)-- Arbitrary Literal String Type * [PEP 655](https://www.python.org/dev/peps/pep-0655/)-- Marking individual TypedDict items as required or potentially-missing * [bpo-46752](https://bugs.python.org/issue46752)-- Introduce task groups to asyncio * The Faster Cpython Project <https://github.com/faster-cpython> is already yielding some exciting results. Python 3.11 is up to 10-60% faster than Python 3.10. On average, we measured a 1.22x speedup on the standard benchmark suite. See Faster CPython <https://docs.python.org/3.11/whatsnew/3.11.html#faster-cpython>for details. * Hey, **fellow core developer,** if a feature you find important is missing from this list, let me know. The next pre-release of Python 3.11 will be 3.11.0b2, currently scheduled for Monday, 2022-05-30. # More resources * [Online Documentation](https://docs.python.org/3.11/) * [PEP 664](https://www.python.org/dev/peps/pep-0664/), 3.11 Release Schedule * Report bugs at [https://bugs.python.org](https://bugs.python.org). * [Help fund Python and its community](/psf/donations/). # And now for something completely different The holographic principle is a tenet of string theories and a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a lower-dimensional boundary to the region—such as a light-like boundary like a gravitational horizon. First proposed by Gerard 't Hooft, it was given a precise string-theory interpretation by Leonard Susskind, who combined his ideas with previous ones of 't Hooft and Charles Thorn.[ Leonard Susskind said, “The three-dimensional world of ordinary experience––the universe filled with galaxies, stars, planets, houses, boulders, and people––is a hologram, an image of reality cited on a distant two-dimensional (2D) surface." As pointed out by Raphael Bousso, Thorn observed in 1978 that string theory admits a lower-dimensional description in which gravity emerges from it in what would now be called a holographic way. The holographic principle was inspired by black hole thermodynamics, which conjectures that the maximal entropy in any region scales with the radius squared, and not cubed as might be expected. In the case of a black hole, the insight was that the informational content of all the objects that have fallen into the hole might be entirely contained in surface fluctuations of the event horizon. The holographic principle resolves the black hole information paradox within the framework of string theory. However, there exist classical solutions to the Einstein equations that allow values of the entropy larger than those allowed by an area law, hence in principle larger than those of a black hole. These are the so-called "Wheeler's bags of gold". The existence of such solutions conflicts with the holographic interpretation, and their effects in a quantum theory of gravity including the holographic principle are not fully understood yet. # We hope you enjoy the new releases!

RELEASED: blue 0.9.0
by Barry Warsaw May 2, 2022

May 2, 2022

We’re happy to announce version 0.9.0 of blue, the somewhat less uncompromising code formatter than black. blue changes a few defaults, such as preferring single quotes instead of double quotes. Here is a brief list of differences from black: * blue defaults to single-quoted strings for everything except docstrings and triple quoted strings. * blue defaults to line lengths of 79 characters. * blue preserves the whitespace before the hash mark for right hanging comments. * blue supports multiple config files: pyproject.toml, setup.cfg, tox.ini, and .blue. Changes since 0.8.0: * Fix test suite failures due to a confluence of problems (GH#74) * Upgrade dependency on Black to 22.1.0 to support Python 3.10 (GH#67) * Add link to demo site at https://iblueit.dev (GH#69) Notice that last bullet item - you can play with blue online! For details see https://blue.readthedocs.io/en/latest/ Enjoy! -Barry (on behalf of the blue developers)

Nikola v8.2.2 is out!
by Chris Warrick May 1, 2022

May 1, 2022

On behalf of the Nikola team, I am pleased to announce the immediate availability of Nikola v8.2.2. This is a bugfix release, whose only change is support for the latest version of Pygments. What is Nikola? =============== Nikola is a static site and blog generator, written in Python. It can use Mako and Jinja2 templates, and input in many popular markup formats, such as reStructuredText and Markdown — and can even turn Jupyter Notebooks into blog posts! It also supports image galleries, and is multilingual. Nikola is flexible, and page builds are extremely fast, courtesy of doit (which is rebuilding only what has been changed). Find out more at the website: https://getnikola.com/ Downloads ========= Install using `pip install Nikola`. Changes ======= * Compatibility with Pygments 2.12.0 (Issue #3617, #3618) -- Chris Warrick <https://chriswarrick.com> PGP: 5EAAEA16
