TatSu 5.13.0
by Juancarlo Añez Dec. 25, 2025

Dec. 25, 2025

竜 TatSu is a tool that takes grammars in a variation of EBNF as input, and outputs memoizing (Packrat) PEG parsers in Python. In this release: - remove comments_re and eol_comments_re from parser configuration (ParserConfig). Use comments and/or eol_comments instead (#351) - do not apply re.MULTILINE to compiled regexes. Users must add (?m) to the expressions for multiline (#351) - cache compiled regexes for performance - fix bug in positive joins (#342) - test with Python 3.13 and latest libraries -- Juancarlo Añez mailto:[email protected]

Oct. 31, 2025

Hi All, I am happy to announce **func-validator 1.2.0** release, this version provides custom error messages for validators via the "err_msg" optional keyword argument. This package was inspired by MATLAB’s argument validation framework, bringing a similar level of clarity and structure to Python function definitions. Below is a quick example: ```python from typing import Annotated from func_validator import validate_params, MustBePositive, MustBeNegative @validate_params def func(a: Annotated[int, MustBePositive(err_msg="a must be greater than 0")], b: Annotated[float, MustBeNegative(err_msg="b must be less than 0")]): ... ``` **Links** * PYPI: https://pypi.org/project/func-validator/ * GitHub: https://github.com/patrickboateng/func-validator * Docs: https://func-validator.readthedocs.io/en/latest/ **Install** pip install func-validator Compatible with Python 3.11 - 3.13.

by Marc-Andre Lemburg Oct. 31, 2025

Oct. 31, 2025

Call for Participation We are happy to announce that we will again be running a*Python devroom at FOSDEM 2026*. The next edition of FOSDEM will take place on January 31 and February 1 2026, with the Python devroom currently scheduled for Saturday, January 31, in the afternoon. If you haven’t heard about FOSDEM before or are looking for more information, you can visit the official website athttps://www.fosdem.org/. As usual, we are looking for multiple Pythonistas to help us shape the devroom schedule. We are now open to receiving your proposals ! With over 8500 participants, FOSDEM is the perfect place to share your story and meet fellow Python enthusiasts. Good luck to everyone applying. We’re looking forward to meeting you all at FOSDEM 2026 ! About FOSDEM * Official FOSDEM 2026 website <https://fosdem.org/2026/> * FOSDEM Code of Conduct <https://fosdem.org/2026/practical/conduct/> FOSDEM is a free and non-commercial event organized by the community for the community. The goal is to provide free and open source software developers and communities a place to meet to: * get in touch with other developers and projects; * be informed about the latest developments in the free software world; * be informed about the latest developments in the open source world; * attend interesting talks and presentations on various topics by project leaders and contributors; * promote the development and benefits of free software and open source solutions. Participation and attendance is totally free, though the FOSDEM organizers gratefully accept donations and sponsorship. Essential Information The Python devroom is currently scheduled to be held on January 31 in the afternoon. * *Submission deadline: December 1 2025* * There will be no extension of the deadline * Announcement of the schedule: December 15 2025 * The reference time is Brussels local lime (CET). * Talk format: 25 minutes presentation, including Q&A, if any. In-person only. * Live streaming of the talks will be available. Speaker Guidelines Please submit your talk proposals using theCFP submission page <https://pretalx.fosdem.org/fosdem-2026/cfp>. * FOSDEM is using a self-hosted Pretalx installation for managing talk submissions. You will need to create an account, if you don’t already have one. * In the Submission notes field, please also confirm that if your talk is accepted, you will be able to attend FOSDEM and deliver your presentation. We will not consider proposals from prospective speakers who are unsure whether they will be able to secure funds for travel and lodging to attend FOSDEM. Sadly, we are not able to offer travel funding for prospective speakers. * You will need to select the "*Python*" track * Keep in mind presentations must be related to Python. All presentations will be recorded and made available under the Creative Commons licenses CC-BY-SA or CC-BY. Captured footage will later be shared online using the FOSDEM archives. By submitting you also agree to these terms. List of Desirable Topics We'd like to make the devroom topics as diverse as possible, so we are looking to offer a mixture of presentations, short tutorials, demos, live coding, etc. This year, the python devroom will focus both on the language itself (new developments, tools and best practices) and its broader applications in education, data science and emerging fields. Examples of these include the following: * How to start as a Python developer * Code infrastructure & starting new projects, e.g. with community-backed tools like uv or pixi * Testing/CI best practices; apps or libraries * Performant Python code * Making use of 3.13t (free-threaded Python with no GIL lock) * Sustainable Python code * How to do/my cool thing/in Python * Python as a tool for education * How to contribute to the Python language * Python 3.13, 3.14, 3.15: What's new? * Python in data analysis & visualization tools * Python in AI & machine learning * Reproducibility and best-practices (e.g. lockfile usage) * The scientific Python ecosystem * How to write secure Python code * Python governance structure * Python success stories * Interoperability and cross-language bindings for Python * New Python projects Volunteers We will also call for volunteers to help us run the event and help us with the devroom operation. Please email the organizers, in case you are interested. Organizers You can reach out directly to the organizers, if you have a specific request or question: * Marc-André Lemburg: mal+fosdem [at] egenix.com * Rosie Wood: rwood [at] turing.ac.uk -- Marc-Andre Lemburg

ANN: psutil 7.1.2 released
by Giampaolo Rodola' Oct. 25, 2025

Oct. 25, 2025

Hello all, I'm glad to announce the release of psutil 7.1.2: https://github.com/giampaolo/psutil A detailed blogport is available at: https://gmpy.dev/blog/2025/wheels-for-free-threaded-python-now-available-in… About ===== psutil (process and system utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports Linux, Windows, macOS, Sun Solaris, FreeBSD, OpenBSD, NetBSD and AIX. Supported Python versions are cPython 3.6+ and PyPy. What's new ========== 2025-10-25 **Enhancements** - #2657: stop publishing prebuilt Linux and Windows wheels for 32-bit Python. 32-bit CPython is still supported, but psutil must now be built from source. 2565_: produce wheels for free-thread cPython 3.13 and 3.14 (patch by Lysandros Nikolaou) **Bug fixes** - #2650, [macOS]: `Process.cmdline()`_ and `Process.environ()`_ may incorrectly raise `NoSuchProcess`_ instead of `ZombieProcess`_. - #2658, [macOS]: double ``free()`` in `Process.environ()`_ when it fails internally. This posed a risk of segfault. - #2662, [macOS]: massive C code cleanup to guard against possible segfaults which were (not so) sporadically spotted on CI. **Compatibility notes** - #2657: stop publishing prebuilt Linux and Windows wheels for 32-bit Python.

by Patrick Boateng Oct. 17, 2025

Oct. 17, 2025

Hi All, I am happy to announce **func-validator 1.1.1** , which provides argument validation for python functions and methods. The main objective is to remove argument validation from the function's body which reduces lines of code and improves code readability. This package was inspired by MATLAB’s argument validation framework, bringing a similar level of clarity and structure to Python function definitions. Below is a quick example: ```python from typing import Annotated from func_validator import validate_params, MustBePositive, MustBeNegative @validate_params def func(a: Annotated[int, MustBePositive()], b: Annotated[float, MustBeNegative()]): ... ``` **Links** * PYPI: https://pypi.org/project/func-validator/ * GitHub: https://github.com/patrickboateng/func-validator * Docs: https://func-validator.readthedocs.io/en/latest/ **Install** pip install func-validator Compatible with Python 3.11 - 3.13.
