    ChatGPT celebrates episode 400!

    Welcome to the big 4-0-0, Pythonistas!

    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!

    Ɓukasz LangaPython 3.13.0RC2 is the final preview releaseOfficial 3.13.0 scheduled for Oct 1Call 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 yetsee issue 320Security releases for3.12.6, 3.11.10, 3.10.15, 3.9.20, and 3.8.203.12.6 has binary installers, but for MacOS, only MacOS 10.13 and newer are supported3.11.10, 3.10.15, 3.9.20, and 3.8.20 do NOT include binary installers.3.8 EOL's in October

    Brian #3: 10 years of sustainable open source - Read the Docs

    Eric HolscherRead 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 2010readthedocs.com (for Business) started in 2014Sustainability model.org has a single non-tracking ad .com is a paid service for companiesThings that didn’t workdonations and other optional support - led to burnoutconsulting and services- took too much time away from core productgrant funding - nice, but one time thingLessonsYou 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.AlsoRtD is not just for Sphinx anymore.

    Michael #1: Why I Still Use Python Virtual Environments in Docker

    by Hynek SchlawackI 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 Everitt37% contribute to open source. Awesome.Favorite Resources: PodcastsLots of familiar faces there. Awesome. Perhaps I shouldn’t have decided to move “Python Test” back to Test & CodeUsage“Data analysis” down, but I think that’s because “data engineering” is added.Data, Web dev, ML, devops, academic, Testing is down 23%Python VersionsStill some 2 out thereMost folks on 3.10-3.12Install from: mostly python.orgFrameworksweb: Flask, Django, Requests, FastAPI 
testing: pytest, unittest, mock, doctest, tox, hypothesis, nose (2% might be the Python 2 people)Data science77% use pandas, 72% NumPyOS: Windows still at 55% Packaging: venv up to 55%I imaging uv will be on the list next yearrequirements.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-inPowered by PyScript, an Anaconda supported open source project that runs Python locally without install and setupFeaturesCells Run IndependentlyRange to Multiple Typesinit.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 LordInteresting discussion of as they happen or batching of upsates to dependenciesdependencies come inrequirements filesGH Actions in CI workflowspre-commit hooksDavid 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 dependenciesNew processRun 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 BiermaIt 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 RennieThis 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”. TIL

    "Is the Tao in a hand-held calculator?" asked the novice.

    "It is," came the reply.

    "Is the Tao in a video game?" continued the novice.

    "It is even in a video game," said the master.

    "And is the Tao in the DOS for a personal computer?"

    The master coughed and shifted his position slightly. "The lesson is over for today," he said.

    Brian #2: Python’s Supportive and Welcoming Environment is Tightly Coupled to Its Progress

    “Python is as popular as it is today because we have gone above and beyond to make this a welcoming community. 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 welcomingPlease 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.”

    Brian #4: PEP 751 – A file format to list Python dependencies for installation reproducibility

    Brett CannonMotivationCurrently, 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.RationaleThe 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.

    Suggested by Galen SwintSee also JFrog blog: Binary secret scanning helped us prevent (what might have been) the worst supply chain attack you can imagineA GitHub access token found it’s way into a .pyc file, then into a docker image.JFrog found it through some regular scans.JFrog notified PYPI security.Token was destroyed within 17 minutes. (nice turnaround)Followup scan revealed that no harm was done.Takaways (from Ee Durbin): Set aggressive expiration dates for API tokens (If you need them at all)Treat .pyc files as if they were source codePerform builds on automated systems from clean source only.

    Michael #1: Vendorize packages from PyPI

    Allows pure-Python dependencies to be vendorized: that is, the Python source of the dependency is copied into your own package.Best used for small, pure-Python dependencies

    Brian #2: A Guide to Python's Weak References Using weakref Module

    Martin HeinzVery cool discussion of weakrefQuick garbage collection intro, and how references and weak references are used.Using weak references to build data structures.Example of two kinds of treesImplementing the Observer patternHow logging and OrderedDict use weak references

    Brian #1: Joining Strings in Python: A "Huh" Moment

    Veronica Berglyd Olsen

    Standard solution to “read lines from a file, do some filtering, create a multiline string”:

    f = open("input_file.txt")filtered_text = "\n".join(x for x in f if not x.startswith("#"))

    This uses a generator, file reading, and passes the generator to join.

    Another approach is to add brackets and pass that generator to a list comprehension:

    f = open("input_file.txt")filtered_text = "\n".join([x for x in f if not x.startswith("#")])

    At first glance, this seems to just be extra typing, but it’s actually faster by 16% on CPython due to the implementation of .join() doing 2 passes on input if passed a generator.

    From Trey Hunner: “I do know that it’s not possible to do 2 passes over a generator (since it’d be exhausted after the first pass) so from my understanding, the generator version requires an extra step of storing all the items in a list first.”

    Michael #2: 10 hard-to-swallow truths they won't tell you about software engineer job

    College will not prepare you for the jobYou will rarely get greenfield projectsNobody gives a BLANK about your clean codeYou will sometimes work with incompetent peopleGet used to being in meetings for hoursThey will ask you for estimates a lot of timesBugs will be your arch-enemy for lifeUncertainty will be your toxic friendIt will be almost impossible to disconnect from your jobYou will profit more from good soft skills than from good technical skills

    Brian #3: My thoughts on Python in Excel

    Felix ZumsteinInteresting take on one person’s experience with trying Python in Excel.“We wanted an alternative to VBA, but got an alternative to the Excel formula language”“Python runs in the cloud on Azure Container Instances and not inside Excel.”“DataFrames are great, but so are NumPy arrays and lists.”
 lots of other interesting takaways.
