Large Language Models (LLMs) have become powerful tools for annotating unstructured data. However, most existing workflows rely on ad hoc scripts, making reproducibility, robustness, and systematic evaluation difficult.

For depth-limited search with transposition tables, we introduce a witness-based correctness criterion and apply it to two representative algorithms. All verification artifacts, including proofs and Python implementations, are publicly available.

Computation of Graph Polynomials via Tree Decomposition: Theory, Algorithms, and Python Implementation
Graph polynomials encode fundamental combinatorial invariants of graphs. Their computation is investigated using tree and path decomposition frameworks, with formal definitions of treewidth, k-trees, and pathwidth establishing the structural basis for algorithmic efficiency. Explicit algorithms are constructed for each polynomial, leveraging decomposition order and state transformation mappings to enable tractable computation on graphs of bounded treewidth. Python implementations validate the m…

Navigating the Python Type Jungle
Python's typing system has evolved pragmatically into a powerful but theoretically fragmented system, with scattered specifications. This paper proposes a formalization to address this fragmentation. The central contribution is a formal foundation that uses concepts from type theory to demonstrate that Python's type system can be elegantly described. This work aims to serve as a crucial first step toward the future development of type inference tools.

Me after opening code I wrote last week: Oh yeah, now I remember.

I’m somewhat exhausted to announce attrs 25.4.0!
The main reason for this release (and why it's published today) is that it ships the first pieces of work for Python 3.14 and PEP 749. There will be more work required and there's going to be a lot more churn once everyone starts testing 3.14 earnestly. We hope to receive more feedback before spending more time on this. #Python

A High-Precision, Differentiable Code for Solar System Ephemerides
We present jorbit, a python/JAX library designed to enable modern data-driven numerical studies of the solar system. Written entirely in JAX, an auto-differentiable and optionally GPU accelerated language behind many current large-scale machine learning efforts, jorbit includes an independent implementation of REBOUND's IAS15 integrator and the ability to parse precomputed ephemerides such as the JPL DE series. In its default behavior, jorbit maintains ~1 mas agreement with JPL Horizons on ~dec…

So #Zope released new versions of their packages, with pkg-resources style namespace removal.
Totally normal way to do the bumps:
1. At first, keep the existing testing hack (writing `__init__.py`).
2. Notice that the next package fails because it expects test paths relative to `zope` subdirectory. Skip it for now.
3. While doing the next package, realize you could remove that hack and simply run tests within the `zope` subdirectory! Go back and update all the previous packages, including the one that failed before.
4. Back to bumping. Notice that in the very next package you've had an even better solution: instead of `cd`, you just called `python -m unittest -s …`. Go back and update all the previous packages.
5. Back to bumping. The very next package turns out to actually expects test paths relative to the top-level site-packages directory. Well, you can use a hybrid of the `__init__.py` hack with `python -m unittest -s …`.

Optimizing Code Embeddings and ML Classifiers for Python Source Code Vulnerability Detection
In recent years, the growing complexity and scale of source code have rendered manual software vulnerability detection increasingly impractical. To address this challenge, automated approaches leveraging machine learning and code embeddings have gained substantial attention. This study investigates the optimal combination of code embedding techniques and machine learning classifiers for vulnerability detection in Python source code. We evaluate three embedding techniques, i.e., Word2Vec, CodeBE…

O, fajno. Wygląda na to, że do wsparcia Pythona 3.14 w #Django w #Gentoo brakowało tylko jednej łatki. I działa!

Analysing Python Machine Learning Notebooks with Moose
Machine Learning (ML) code, particularly within notebooks, often exhibits lower quality compared to traditional software. Bad practices arise at three distinct levels: general Python coding conventions, the organizational structure of the notebook itself, and ML-specific aspects such as reproducibility and correct API usage. However, existing analysis tools typically focus on only one of these levels and struggle to capture ML-specific semantics, limiting their ability to detect issues. This pa…

hot take: a big reason for the collective anxiety around free-threading is the result of decades of copium where we assured each other that it's good, actually, that #Python has a bad threading story, because threads are dAnGeRoUs and our feeble minds need protection

It's official: #CPython is planning to kill the #Gentoo WD40 profiles.

attrs will have a way to introspect the EFFECTIVE class build parameters in the next version. I swear to Cthulhu I thought this PR is gonna kill me (there's been A LOT more private hence and forth in the background), but I'm happy how it turned out: https://github.com/python-attrs/attrs/pu…

I did not make any good progress on my project to read GPX data with Python today. (Trying to read speed.) May need to just read it as XML.
There are a bunch of nerds who do Python and bikes though, so someone might have the code example I need.
