Michael #1: “We must replace uwsgi by something else” uWSGI is now in maintenance mode: https://uwsgi-docs.readthedocs.io/en/latest/ The project is in maintenance mode (only bugfixes and updates for new languages apis). Do not expect quick answers on github issues and/or pull requests (sorry for that) A big thanks to all of the users and contributors since 2009. Reasonable options look like: granian uvicorn hypercorn gunicorn (potentially with uvicorn workers for async) Brian #2: Let’s build and optimize a Rust extension for Python Itamar Turner-Trauring Example: algorithm for approximating the number of unique values in a list Comparison to non-approximation non-approx is faster but uses way more memory Rust version Use Maturin and PyO3 Pull in Rust dependencies (rand for random numbers) Optimization link-time optimization faster random store hashes only Future optimizations change algorithm maybe pass numpy array instead of Python list (I’d like to see that spedup) Michael #3: Fake recruiter coding tests target devs with malicious Python packages via python weekly GitHub projects that have been linked to previous, targeted attacks in which developers are lured using fake job interviews. Attackers posing as employees of major financial services firms. This previously happened via other means such as NPM This analysis revealed that the direct parent of the detected, malicious files is a PythonPYC file, meaning that once again the team encountered malware hidden in a compiled Python file. “The README files tell would-be candidates to make sure the project is running successfully on their system before making modifications.” What can you do (according to Michael)? Try out new packages in a docker container Work on code and projects using a VM which has snapshotting (to roll back completely after you’re done) Fire up a Windows desktop in the cloud for the project then destroy it Brian #4: Monthly PSF Board Office Hours “The Office Hours will be sessions where you can share with us how we can help your community, express your perspectives, and provide feedback for the PSF.” “Unless we have a dedicated topic for a session, you are not limited to talking with us about the above topics, although the discussions should be focused on Python, the PSF, and our community.

It's hard to believe we're celebrating the 400th episode of Python Bytes! From the early days of byte-sized Python news to becoming the source for all things Python, it’s been a wild ride. We've laughed over code quirks, gasped at new libraries, and said farewell to the GIL together. Whether you're a seasoned developer, a curious learner, or just here for the witty banter, you’ve been an essential part of this journey. To Michael and Brian: You've built a community that turns import this into more than just Zen—it's a family of passionate Pythonistas. Your dedication, insights, and humor make this show more than just tech news. It’s a weekly celebration of what we love about Python and why we keep coming back for more. Here’s to the next 400 episodes—may your code be bug-free, your tests pass on the first run, and your Python version always be up to date. Brian #1: Python 3.13.0RC2, 3.12.6, 3.11.10, 3.10.15, 3.9.20, and 3.8.20 are now available! Łukasz Langa Python 3.13.0RC2 is the final preview release Official 3.13.0 scheduled for Oct 1 Call to action “We strongly encourage maintainers of third-party Python projects to prepare their projects for 3.13 compatibilities during this phase, and where necessary publish Python 3.13 wheels on PyPI to be ready for the final release of 3.13.0. Any binary wheels built against Python 3.13.0rc2 will work with future versions of Python 3.13. As always, report any issues to the Python bug tracker .” “Please keep in mind that this is a preview release and while it’s as close to the final release as we can get it, its use is not recommended for production environments.” Note: uv python does not support 3.13 yet see issue 320 Security releases for 3.12.6, 3.11.10, 3.10.15, 3.9.20, and 3.8.20 3.12.6 has binary installers, but for MacOS, only MacOS 10.13 and newer are supported 3.11.10, 3.10.15, 3.9.20, and 3.8.20 do NOT include binary installers. 3.8 EOL's in October Michael #2: Docker images using uv's python See #396: uv-ing your way to Python and #398: Open source makes you rich? (and other myths) for the opening discussions Talk Python episode on uv is out uv venv --python gets Python from python-build-standalone by Gregory Szorc Took our Docker build times from 10 minutes to 8 seconds for the base image and 800ms (!) for our app platforms Brian #3: 10 years of sustainable open source - Read the Docs Eric Holscher Read the Docs has been a company for 10 years “a team of 4 folks working full-time on Read the Docs.” readthedocs.org started in 2010 readthedocs.com (for Business) started in 2014 Sustainability model .org has a single non-tracking ad .com is a paid service for companies Things that didn’t work donations and other optional support - led to burnout consulting and services- took too much time away from core product grant funding - nice, but one time thing Lessons You don't get extra points for being bootstrapped. Compete by doing things you can do better due to niche and size. Keeping trust in the community is the most important thing. Contribution is easier for less complex parts of the code base. Beign open source means capturing a small percentage of the value you create. You have to be ok doing more with less. Also RtD is not just for Sphinx anymore. Their build system now supports any documentation tool. Michael #4: humanize by Hugo van Kemenade (Python 3.14 & 3.15 release manager & core developer) Not too many variations, but very handy if you need it. Numbers Associated Press style (“seven” and “10”) Clamp (under 1.0 million) Fractional (1/3) Int Word (1.2 Billion) Metric (1.5 kV) Ordinal (112th) scientific Time File size Extras Brian: Test & Code is now again Test & Code The two part series on Python imports that started in June is finally complete with episode 222.

AI transcription, so there’s things like .pie, .pi, and dot pie where it should be .py Michael: Final final call for Coding in a Castle event with Michael iStats Menu Anaconda Code Runner by Ruud van der Ham: With Anaconda Coide we can -at last- run that code locally and import (most) Python modules. But if you want to run a significant amount of code, you have to put that in a cell or publish it to PyPI or a wheel and import it. That's why I have developed a general-purpose runner function that runs arbitrary code located on an Excel sheet with AnacondaCode. Joke: When beginners learn a new programming language...

Michael #1: Why I Still Use Python Virtual Environments in Docker by Hynek Schlawack I was going to cover Production-ready Docker Containers with uv but decided to take this diversion instead. Spend a lot of time thinking about the secondary effects of what you do. venvs are well known and well documented. Let’s use them. Brian #2: Python Developer Survey Results “… official Python Developers Survey, conducted as a collaborative effort between the Python Software Foundation and JetBrains.” Python w/ Rust rising, but still only 7% ““The drop in HTML/CSS/JS might show that data science is increasing its share of Python.” - Paul Everitt 37% contribute to open source. Awesome. Favorite Resources: Podcasts Lots of familiar faces there. Awesome. Perhaps I shouldn’t have decided to move “Python Test” back to Test & Code Usage “Data analysis” down, but I think that’s because “data engineering” is added. Data, Web dev, ML, devops, academic, Testing is down 23% Python Versions Still some 2 out there Most folks on 3.10-3.12 Install from: mostly python.org Frameworks web: Flask, Django, Requests, FastAPI … testing: pytest, unittest, mock, doctest, tox, hypothesis, nose (2% might be the Python 2 people) Data science 77% use pandas, 72% NumPy OS: Windows still at 55% Packaging: venv up to 55% I imaging uv will be on the list next year requirements.txt 63%, pyproject.toml 32% virtual env in containers? 47% say no Michael #3: Anaconda Code add-in for Microsoft Excel Run their Python-powered projects in Excel locally with the Anaconda Code add-in Powered by PyScript, an Anaconda supported open source project that runs Python locally without install and setup Features Cells Run Independently Range to Multiple Types init.py file is static and cannot be edited, with Anaconda Code, users have the ability to access and edit imports and definitions, allowing you to write top-level functions and classes and reuse them wherever you need. A Customizable Environment Brian #4: Disabling Scheduled Dependency Updates David Lord Interesting discussion of as they happen or batching of upsates to dependencies dependencies come in requirements files GH Actions in CI workflows pre-commit hooks David was seeing 60 PRs per month when set up on monthly updates (3 ecosystems * 20 projects) new tool for updating GH actions: gha-update, allows for local updating of GH dependencies New process Run pip-compile, gha-update, and pre-commit locally. Update a project’s dependencies when actively working on the project, not just whenever a dependency updates. Note that this works fine for dev dependencies, less so for security updates from run time dependencies. But for libraries, runtime dependencies are usually not pinned.

Michael #1: pyawaitable CPython API for asynchronous functions. by Peter Bierma It was originally designed to be directly part of CPython - you can read the scrapped PEP about it. Since this library only uses the public ABI, it's better fit outside of CPython, as a library. Brian #2: Annotated area charts with plotnine Nicola Rennie This is a marvelous, very professional looking plot, and a tutorial for how to achieve it. Uses plotline, which is “.. an implementation of a grammar of graphics in Python based on ggplot2” I actually didn’t know the gg in ggplot came from “grammar of graphics”.

Being a friendly and supportive community is part of how we are perceived by the wider world and is integral to the wide popularity of Python. We won a “Wonderfully Welcoming Award” last year at GitHub Universe. Over and over again, the tech press refers to Python as a supportive community.” Some communication recently, with the recent bylaws change, didn’t live up to our promise to be welcoming Please read the article for more details. Another quote: “We have a moral imperative – as one of the very best places to bring new people into tech and into open source – to keep being good at welcoming new people. If we do not rise and continue to rise every day to this task, then we are not fulfilling our own mission, “to support and facilitate the growth of a diverse and international community of Python programmers.” Technical skills are a game-changer for the people who acquire them and joining a vast global network of people with similar interests opens many doors. Behavior that contributes to a hostile environment around Python or throws up barriers and obstacles to those who would join the Python community must be addressed because it endangers what we have built here.” Michael #3: Status pages for sites! Based on Uptime Kuma I covered last week Python Bytes status Talk Python status Brian #4: PEP 751 – A file format to list Python dependencies for installation reproducibility Brett Cannon Motivation Currently, no standard exists to: Specify what top-level dependencies should be installed into a Python environment. Create an immutable record, such as a lock file, of which dependencies were installed. Considering there are at least five well-known solutions to this problem in the community (pip freeze, pip-tools, uv, Poetry, and PDM), there seems to be an appetite for lock files in general. Rationale The format is designed so that a locker which produces the lock file and an installer which consumes the lock file can be separate tools. … The file format is designed to be human-readable. …Finally, the format is designed so that viewing a diff of the file is easy by centralizing relevant details. The file format is also designed to not require a resolver at install time. … Extras Brian: Hello, pytest! course is going well, and is purchasable as in pre-release mode. Planning on Aug 19 (or before) deadline. Not sure what the final price will be, but I’m starting with $10.
