We have updated the FastAPI extensions. It is very surprising to us that millions of extensions are being downloaded that have not been updated for over a year. www.python4data.science/en/latest/da... @fastapi.tiangolo.com #Python #FastAPI #REST

how did i not know about tox's version range syntax!? (i.e., 3{9-14} == 3{9,10,11,12,13,14}) 😍 (added in tox 4.25.0 on 2025-03-27) #python

I took a look at the changes coming with Python 3.15 – and I can't wait to put them to productive use. I've already updated our tutorials: • Performance measurements: www.python4data.science/en/latest/pe... • Tachyon: www.python4data.science/en/latest/pe... #Python

With ty, Astral has released a fast Python type checker and language server (LSP): astral.sh/blog/ty It can also be easily integrated into Visual Studio Code and other editors: marketplace.visualstudio.com/items?itemNa... docs.astral.sh/ty/reference... #Python #Typechecker #LSP #Code

The study ‘Does AI-Assisted Coding Deliver?’ corresponds quite well with our experiences: ‘The age of AI coding has arrived – our challenge now is to harness it wisely.’ arxiv.org/pdf/2511.044... #AI #Coding #Cursor

We have updated the section on pytest with many exciting use cases * on command line options * on generating markers * and on parameterising exceptions python-basics-tutorial.readthedocs.io/en/latest/te... #Python #Testing #pytest

📆 Save the date and reserve your place – on 25 November, there will be a Lightning talk and social night: www.meetup.com/python-users... #Python #Berlin

Our workshop on Python and Rust will begin in a few hours. We look forward to seeing you there. www.meetup.com/python-users... #Python #Rust #Berlin

I’m currently organising the Xmas party for all Berlin Python user groups again 🎄🦌❄️ www.meetup.com/python-users... I’m really looking forward to celebrating with all Pythonistas again soon. @python.berlin @pyladiesberlin.bsky.social @djangogirls.bsky.social #Python #Berlin

Version 2.0 of the Principles of Open Scholarly Infrastructure is out! This version is the result of a review of the version 1.1 principles by the #POSI Adopters and consultation with the community to create version 2.0: openscholarlyinfrastructure.org

We have updated our tutorial to data management with DVC. It also allows you to create lightweight data science and data modelling workflows and execute them in a parameterised manner: www.python4data.science/en/latest/pr... #Data #Versioncontrol #Git #DataScience #Modeling #Python

Today is #WorldStatisticsDay, and the 20th anniversary of the European Statistics Code of Practice (CoP). This code aims to ensure that official statistics in Europe are produced and made available independently, with high data quality and according to the same standards: #OpenData #OpenGovernment

After a very intensive workshop on test-driven and behaviour-driven development as well as data validation pipelines, I’m now looking forward to a relaxing weekend.

Today, a customer lost some changes due to git stach drop. This meant that they were no longer accessible with git reflog. As a last resort, git fsck came to our rescue: www.python4data.science/en/latest/pr... #git

Thanks @hugovk.dev! I haven’t been this excited about a #Python release in a long time. I’m curious to see how some of our projects will fare with free-threaded Python: cusy.io/en/blog/free...

The most important finding of the DORA Report 2025 is that AI is an amplifier in software development: it amplifies the strengths of high-performing companies and the weaknesses of companies struggling with difficulties: cusy.io/en/blog/dora... #DORA #AI #DevOps

On 30 October, there will be a workshop with Travis on hybrid projects with Python and Rust: www.meetup.com/python-users... #Python #Berlin #rustlang

Now we have also described how to use uv reliably for Cursor: www.python4data.science/en/latest/pr... #CursorAI #Python #Packaging #uv

Since we have recently been asked frequently whether pandas is slow and whether we should use Polars, Dask or DuckDB instead, we have now provided an initial overview of the various technologies: www.python4data.science/en/latest/wo... #Python #Performance #DuckDB

🚨 There is a new ongoing phishing campaign against PyPI users. This campaign uses the same tactics as the previous campaign targeting PyPI users, but with a new domain. Read more about what steps we're taking to protect PyPI users from future campaigns:

During their latest tour stop, Massive Attack shocked fans by integrating facial recognition into the show itself. Live video feeds captured audience faces, processing them through recognition software and projecting the results as part of the visual experience. www.gadgetreview.com/massive-atta...

We have now completely switched to pathlib: python-basics-tutorial.readthedocs.io/en/latest/sa... #Python

In a few weeks, Python 3.14 will be released with full support for free-threaded Python. But does this really represent a breakthrough in concurrent code execution? We took a closer look at recent progress: cusy.io/en/blog/free... #Python

I made it onto the #Python Bytes podcast with a contribution on measuring the performance of prek: pythonbytes.fm/episodes/sho... with @brianokken.bsky.social and @mkennedy.codes

#TIL about prek, a rewrite of pre-commit written in Rust. And as expected, it is extremely fast: prek.j178.dev #pre-commit #Git #DX

We have finally documented Ruff – the tool greatly simplifies static code analysis for Python projects: www.python4data.science/en/latest/pr... #Python #Ruff

We have now updated our packaging tutorial to include PEP 639, which enables SPDX-compliant licensing: python-basics-tutorial.readthedocs.io/en/latest/pa... #Python #Packaging #SPDX #Licensing

The latest uv release (0.8.13) introduced the experimental uv format. It calls Ruff’s formatter to automatically style your code: github.com/astral-sh/uv.... And you can use [tool.ruff] for both entry points. #Python #uv

Hi Pythonistas! Previously, I was able to use the Trove classifier Private :: Do Not Upload to prevent packages from being accidentally uploaded to PyPI. Is there a similar option with the PEP 639 licence expression? @pypi.org #Python

We have added a section on additional JSON tools: www.python4data.science/en/latest/da... #Python #JSON
