Thanks for your work in Python 3.10
by Pablo Galindo Salgado 05 Oct '21

05 Oct '21

Hi everyone, Now that 3.10.0 is finally released I wanted to take the time to thank you all for all your fantastic work this past year. Is because of the sum of all your fantastic work that Python 3.10 is going to be such a fantastic release. No matter if you have been working in fixing bugs, adding features, improving the documentation, reviewing contributor PRs, helping with the infrastructure, helping with the buildbot fleet, triaging bugs or discussing PEPs and features, your work is tremendously appreciated: you make a tremendous impact in Python and its community. I also wanted to make sure to thank again all the people that helped with the release itself and with the numerous release blockers and also for your patience when I had to delay your feature to 3.11 or your bugfix to 3.10.1. It has been a privilege to be able to release the result of your work to the community! Thank you all, your work really makes a difference. Regards from sunny London, Pablo Galindo Salgado

Worried about Python release schedule and lack of stable C-API
by jack.jansen＠cwi.nl 05 Oct '21

05 Oct '21

I’m getting increasingly worried about the future of Python, and those worries have been exacerbated by the new yearly release rhythm, and the lack of a stable C-API that is full enough to entice extension writers to use it. PyPI packages and wheels are targeted to specific Python versions, which means that any project that depends on some of the larger extension packages (of which there are many, and many of which are must-have for many projects) now start lagging Python versions by years, because somewhere deep down in the dependency graph there is something that is still stuck at Python 3.8 (for example). I fully understand that 3.8 is good enough for the developers of that package, and that they have more pressing things to do than porting to 3.9 or 3.10, but it now keeps any project or package that depends on their software on 3.8 as well. And I also fully understand that some other developer who creates a new package that is essential to my application only targets the current Python release, or maybe one release back, but now if I need both the new package and and older one I’m up the well-known creek without a paddle. Building packages from source has become pretty much impossible nowadays, especially if your project is multi-platform and needs to interface to specific hardware, and you want to do the right thing with CI/CD builds and all that. On Linux/MacOS you have a chance when you try to specify all the dependencies for third party libraries and what not, but on Windows you’re dead in the water. And that is assuming you have the time and are smart enough to back port the new package to the old Python release, or the old package to the new Python release (and for the latter there’s probably a good reason why the developers haven’t done so already). Before you know it you have to install a couple of graphics card APIs for some obscure AI feature used by something you’ve never heard of, Cython for something else, and obscure vendor libraries for something else again. I think we really need to come up with some scheme whereby extension packages become more long-lived than a single Python release... -- Jack Jansen, <Jack.Jansen(a)cwi.nl>, http://www.cwi.nl/~jack If I can't dance I don't want to be part of your revolution -- Emma Goldman

Does ensurepip still have to include a copy of setuptools?
by Illia Volochii 05 Oct '21

05 Oct '21

Hi everyone, ensurepip includes private copies of pip and setuptools. But PEP 453 states that "once pip is able to run pip install --upgrade pip without needing setuptools installed first, then the private copy of setuptools will be removed from ensurepip in subsequent CPython releases." https://www.python.org/dev/peps/pep-0453/#automatic-installation-of-setupto… At the moment pip itself includes a needed part of setuptools. https://github.com/pypa/pip/tree/9c474d4862907ae220ced0fcdbd76660955ff732/s… I experimented with modifying ensurepip in the main branch not to install setuptools, and then used it to install pip. It worked fine. Then I run `./python -m pip install --upgrade pip`, and it upgraded pip successfully. Does this mean that we can drop the copy of setuptools? Note, the venv module has such code `CORE_VENV_DEPS = ('pip', 'setuptools')`. I am not sure whether it requires setuptools from ensurepip. Thanks, Illia

[RELEASE] Python 3.10.0 is available
by Pablo Galindo Salgado 04 Oct '21

04 Oct '21

On behalf of the Python development community and the Python 3.10 release team, I’m pleased to announce the availability of Python 3.10.0. Python 3.10.0 is the newest major release of the Python programming language, and it contains many new features and optimizations. https://www.python.org/downloads/release/python-3100/ # Major new features of the 3.10 series, compared to 3.9 Among the new major new features and changes so far: * [PEP 623](https://www.python.org/dev/peps/pep-0623/) -- Deprecate and prepare for the removal of the wstr member in PyUnicodeObject. * [PEP 604](https://www.python.org/dev/peps/pep-0604/) -- Allow writing union types as X | Y * [PEP 612](https://www.python.org/dev/peps/pep-0612/) -- Parameter Specification Variables * [PEP 626](https://www.python.org/dev/peps/pep-0626/) -- Precise line numbers for debugging and other tools. * [PEP 618 ](https://www.python.org/dev/peps/pep-0618/) -- Add Optional Length-Checking To zip. * [bpo-12782](https://bugs.python.org/issue12782): Parenthesized context managers are now officially allowed. * [PEP 632 ](https://www.python.org/dev/peps/pep-0632/) -- Deprecate distutils module. * [PEP 613 ](https://www.python.org/dev/peps/pep-0613/) -- Explicit Type Aliases * [PEP 634 ](https://www.python.org/dev/peps/pep-0634/) -- Structural Pattern Matching: Specification * [PEP 635 ](https://www.python.org/dev/peps/pep-0635/) -- Structural Pattern Matching: Motivation and Rationale * [PEP 636 ](https://www.python.org/dev/peps/pep-0636/) -- Structural Pattern Matching: Tutorial * [PEP 644 ](https://www.python.org/dev/peps/pep-0644/) -- Require OpenSSL 1.1.1 or newer * [PEP 624 ](https://www.python.org/dev/peps/pep-0624/) -- Remove Py_UNICODE encoder APIs * [PEP 597 ](https://www.python.org/dev/peps/pep-0597/) -- Add optional EncodingWarning [bpo-38605](https://bugs.python.org/issue38605): `from __future__ import annotations` ([PEP 563](https://www.python.org/dev/peps/pep-0563/)) used to be on this list in previous pre-releases but it has been postponed to Python 3.11 due to some compatibility concerns. You can read the Steering Council communication about it [here]( https://mail.python.org/archives/list/python-dev@python.org/thread/CLVXXPQ2…) to learn more. # More resources * [Changelog](https://docs.python.org/3.10/whatsnew/changelog.html#changelog ) * [Online Documentation](https://docs.python.org/3.10/) * [PEP 619](https://www.python.org/dev/peps/pep-0619/), 3.10 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 For a Schwarzschild black hole (a black hole with no rotation or electromagnetic charge), given a free fall particle starting at the event horizon, the maximum propper time it will experience to fall into (which happens when it falls without angular velocity) the singularity is `π*M` (in [natural units](https://en.wikipedia.org/wiki/Natural_units)), where M is the mass of the black hole. For Sagittarius A* (the black hole at the center of the milky way) this time is approximately 1 minute. Schwarzschild black holes are also unique because they have a space-like singularity at their core, which means that the singularity doesn't happen at a specific point in *space* but happens at a specific point in *time* (the future). This means once you are inside the event horizon you cannot point with your finger towards the direction the singularity is located because the singularity happens in your future: no matter where you move, you will "fall" into it. # We hope you enjoy the new releases!

Should I care what -3.14 // inf produces?
by Jeff Allen 02 Oct '21

02 Oct '21

Is an implementation of Python free to make up its own answers to division and modulus operatons in the case of inf and nan arguments? The standard library documentation says only that // is "rounded towards minus infinity". The language reference says that ||: 1. |x == (x//y)*y + (x%y)|, 2. the modulus has the same sign as y, and 3. division by (either kind of) zero raises |ZeroDivisionError| . It's consistent, but it doesn't define the operator over the full range of potential arguments. In Python 3.8 and 3.9: >>> from decimal import Decimal >>> Decimal('-3.14') // Decimal('Infinity') Decimal('-0') >>> -3.14 // float("inf") -1.0 >>> import math >>> math.floor(-3.14 / float("inf")) 0 I can see sense in all three answers, as possible interpretations of "rounded towards minus infinity", but I quite like decimal's. There seem to be no regression tests for floor division of floats, and for modulus only with finite arguments, perhaps intentionally. -- Jeff Allen
