ANN: kubesdk - Fully typed, async-first Python client for Kubernetes
by Beslan Birzhev Jan. 15, 2026

Jan. 15, 2026

The Puzl Cloud team is pleased to announce the open-source release of kubesdk. kubesdk is a modern, async-first Kubernetes client for Python designed to improve ergonomics for day-to-day production automation and multi-cluster workflows. It addresses key limitations of existing solutions by providing: * Async-first design: Built with aiohttp for high-concurrency workloads. * Full Typing: Typed client methods and models for all built-in Kubernetes resources. * Model Generator: A tool to instantly generate Python dataclasses from your own CRDs (Custom Resource Definitions). * Unified Surface: Consistent interface for both core and custom resources. * Multi-cluster support: Built directly into the client for scalable operations. We developed this SDK to solve our own internal needs for reliable Kubernetes automation and are now sharing it with the community.

Guppy 3/Heapy 3.1.6
by YiFei Zhu Jan. 6, 2026

Jan. 6, 2026

I am happy to announce Guppy 3 3.1.6 Guppy 3 is a library and programming environment for Python, currently providing in particular the Heapy subsystem, which supports object and heap memory sizing, profiling and debugging. It also includes a prototypical specification language, the Guppy Specification Language (GSL), which can be used to formally specify aspects of Python programs and generate tests and documentation from a common source. Guppy 3 is a fork of Guppy-PE, created by Sverker Nilsson for Python 2. This release adds support for Python 3.14, and support for Python 3.9 was dropped. Support for free-threaded mode is planned for a future release. This release also fixes a few bugs, including: o Fix a segfault in hv_cli_inrel_classify caused by a GC race o Fix relate of frame objects showing some attributes as exposed to Python when they are not License: MIT The project homepage is on GitHub: https://github.com/zhuyifei1999/guppy3 Enjoy and Happy New Year, YiFei Zhu

ANN: Modu 0.1.0 - Modular arithmetic in Python
by pie.denis＠skynet.be Jan. 3, 2026

Jan. 3, 2026

Hi, I'm glad to announce the release of Modu v0.1.0, a new Python module dedicated to modular arithmetic. Through operator overloading, Modu provides a user experience similar to a "domain-specific language" (DSL), with sets / arithmetic operations using modular arithmetic. Modu is best used as an interactive calculator in Python terminal sessions (REPL) or in Jupyter Notebooks with instantaneous rendering as LaTeX formulae. The prime target domain is research and education in number theory. Modu is an open-source module distributed under the MIT license. - PyPI: https://pypi.org/project/modu/ - GitHub: https://github.com/piedenis/Modu If you want to give it a try, you may follow the link below for the online "Modutorial" (Jupyter Notebook): https://mybinder.org/v2/gh/piedenis/Modu/HEAD?urlpath=%2Fdoc%2Ftree%2Fsrc%2F modutorial.ipynb The present version v0.1.0 is BETA. Any feedback or enhancement ideas are welcome! Pierre Denis
