Sad news from Zurich
by Guido van Rossum 12 ডিসেম্বর, 2021

12 ডিসেম্বর, 2021

A former core dev who works at Google just passed the news that Fredrik Lundh (also known as Effbot) has died. Fredrik was an early Python contributor (e.g. Elementtree and the 're' module) and his enthusiasm for the language and community were inspiring for all who encountered him or his work. He spent countless hours on comp.lang.python answering questions from newbies and advanced users alike. He also co-founded an early Python startup, Secret Labs AB, which among other software released an IDE named PythonWorks. Fredrik also created the Python Imaging Library (PIL) which is still THE way to interact with images in Python, now most often through its Pillow fork. His effbot.org site was a valuable resource for generations of Python users, especially its Tkinter documentation. Fredrik's private Facebook page contains the following message from November 25 by Ylva Larensson (translated from Swedish): """ It is with such sorrow and pain that I write this. Fredrik has left us suddenly. """ A core dev wrote: "I felt privileged to be able to study Fredrik's code and to read his writing. He was a huge asset to our community in the early days. I enjoyed his sense of humor as well. I'm sad that he passed away." We will miss him. -- --Guido van Rossum (python.org/~guido) *Pronouns: he/him **(why is my pronoun here?)* <http://feministing.com/2015/02/03/how-using-they-as-a-singular-pronoun-can-…>

[RELEASE] Python 3.11.0a3 is available
by Pablo Galindo Salgado 8 ডিসেম্বর, 2021

8 ডিসেম্বর, 2021

You can tell that we are slowly getting closer to the first beta as the number of release blockers that we need to fix on every release starts to increase [image: :sweat_smile:] But we did it! Thanks to Steve Dower, Ned Deily, Christian Heimes, Łukasz Langa and Mark Shannon that helped get things ready for this release :) Go get the new version here: https://www.python.org/downloads/release/python-3110a3/ **This is an early developer preview of Python 3.11** # Major new features of the 3.11 series, compared to 3.10 Python 3.11 is still in development. This release, 3.11.0a3 is the third of seven planned alpha releases. Alpha releases are intended to make it easier to test the current state of new features and bug fixes and to test the release process. During the alpha phase, features may be added up until the start of the beta phase (2022-05-06) and, if necessary, may be modified or deleted up until the release candidate phase (2022-08-01). Please keep in mind that this is a preview release and its use is **not** recommended for production environments. 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* * The [Faster Cpython Project](https://github.com/faster-cpython) is already yielding some exciting results: this version of CPython 3.11 is ~12% faster on the geometric mean of the [PyPerformance benchmarks]( speed.python.org), compared to 3.10.0. * 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 3.11.0a4, currently scheduled for Monday, 2022-01-03. # 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 Rayleigh scattering, named after the nineteenth-century British physicist Lord Rayleigh is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. For light frequencies well below the resonance frequency of the scattering particle, the amount of scattering is inversely proportional to the fourth power of the wavelength. Rayleigh scattering results from the electric polarizability of the particles. The oscillating electric field of a light wave acts on the charges within a particle, causing them to move at the same frequency. The particle, therefore, becomes a small radiating dipole whose radiation we see as scattered light. The particles may be individual atoms or molecules; it can occur when light travels through transparent solids and liquids but is most prominently seen in gases. The strong wavelength dependence of the scattering means that shorter (blue) wavelengths are scattered more strongly than longer (red) wavelengths. This results in the indirect blue light coming from all regions of the sky. # We hope you enjoy those new releases! Thanks to all of the many volunteers who help make Python Development and these releases possible!

I hope you like bug fixes, because we have a whole shipment of them! Python 3.10.1 is the first maintenance release of Python 3.10 as we have packed more than 330 commits of fixes and general improvements. You can get it here: https://www.python.org/downloads/release/python-3101/ # This is the first maintenance release of Python 3.10 Python 3.10.1 is the newest major release of the Python programming language, and it contains many new features and optimizations. # 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 The Meissner effect (or Meissner–Ochsenfeld effect) is the expulsion of a magnetic field from a superconductor during its transition to the superconducting state when it is cooled below the critical temperature. This expulsion will repel a nearby magnet. The German physicists Walther Meissner and Robert Ochsenfeld discovered this phenomenon in 1933 by measuring the magnetic field distribution outside superconducting tin and lead samples. The experiment demonstrated for the first time that superconductors were more than just perfect conductors and provided a uniquely defining property of the superconductor state. The ability for the expulsion effect is determined by the nature of equilibrium formed by the neutralization within the unit cell of a superconductor. You can do [ver cool things](https://www.youtube.com/watch?v=HRLvVkkq5GE) with it! # We hope you enjoy the new releases!
