It doesn't matter how long you play the open source game, the first bug report from a downstream redistributor for a new project is a somewhat surreal experience. For all its many challenges, the development of free and open source software is an utterly astonishing feat of global collaboration. #python #venvstacks #conda #foss

Math for programming (Learn the math, write better code). ~ Ronald T. Kneusel. https://books.google.com/books?id=umDTEAAAQBAJ #Math #Python #Programming

Thank you #pyconus for having me as a speaker and for everyone who made that happen. I’m always happy to talk about using code for journalism and to hear how others are using #python in other spaces to understand the world.

I do enjoy how #Python is truly a community effort--lots of people are doing lots of things, with few people wearing multiple hats.

The second one covers a project called "Audiofeeder" which was originally described as "janky as hell", a sentiment I know quite well from my own side projects.

It's a #Python app that uses #Flask to integrate audiobooks into existing podcast players.

There were layoffs at MS yesterday and 3 #Python core devs from the Faster CPython team were caught in them. If you know of any jobs, please send them their way (they kind of know Python, CPython, and its internals well 😉):

Eric Snow: https://www.linkedin.com/in/ericsnowcurrently/

So over to the command line. First, a sudo apt update.

Debian fetches the updates as it should. It says:

"Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
1 package can be upgraded. Run 'apt list --upgradable' to see it."

Apt list --upgradable mentions: monarx-agent/bookworm 4.2.72-master amd64 [upgradable from: 4.2.62-master]

Okay, so with that done, let's try the three commands YunoHost recommended:

sudo apt install --fix-broken produces the following output:

"Reading package lists... Done

0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
1 not fully installed or removed.

And let's try sudo dpkg --audit:

"The following packages are only half configured, probably due to problems
configuring them the first time. The configuration should be retried using
dpkg --configure <package> or the configure menu option in dselect:
yunohost manageable and configured self-hosting server"

Okay.

So.

Any idea what's going on here?

What should I try next to fix this?

Hey Mastodon #python friends, does anyone have a drop-in Python web app that can handle/record likes/posts from Mastodon?

If someone has seen one, I have a design that I want to connect to something that has enough IndieWeb / Mastodon smarts that I can wire it up tonight and I thought I'd ask here first.

I do NOT want to run my own Mastodon instance, but I'd love the pingback feature for a one or two page app.

@faassen One thing they share: Both communities are on average quite nice people in my experience.

I considered joining RustWeek, but could not make it. I hope to attend https://eurorust.eu/ and/or https://rustlab.it/. #rust #Python

The first #Python conferences I ever went to were the only ones in the world and had about 300 people there. Now I am at #RustWeek with comfortably more than double the size and it's just one of the Rust conferences in Europe.

I started with Rust about 5 years ago, and Rust was already a lot bigger at the time than Python was when I started with it.

Stoked for my WebGL tutorial on Thursday morning at @pycon. 3:30h to show all the basic components of 3D graphics? Might be ambitious! But I'll do my best.

Hopefully the conference wi-fi won't betray us 🤞🏻🤞🏻

#PyConUS #PyConUS2025 #Python #PyScript #Threejs

Request for consistency check:

In #Python, if one of my upstreams is broken because of their `build-system.requires`, there isn't any way I can override/augment those requirements from downstream, right?

I'm asking in the context of `pip` but if other tools have a workflow for this problem I would be interested to hear about them

The specific failure mode here is that Cython 3.1.0 just came out, the mostly-abandoned upstream pins `Cython >= 0.27`, and support for something broke in the upgrade.

Things I am aware that I can do that do not meet the requirements of the project:

- Disable build isolation
- Fork/vendor the upstream
- Resolve the entire graph ahead of time and patch the resulting requirements file (I think this *also* requires disabling build isolation)

There are many times working with #python where I wish the standard library logging included a `TRACE` level by default. Would like to be able to use `INFO` and `DEBUG` in my app more easily, without `DEBUG` getting swamped by other library `DEBUG` loggers.
(yes I know I *could* do `logging.getLogger(<library path>).setLevel(...)` I just think it would be easier if there was one extra level of logging)
(I also know the logging levels are numbers spaced 10 apart)

Trying to gather feedback/opinions, especially from #CPython Core Developers, on the recent #fuzzing campaign using #fusil.

https://discuss.python.org/t/feedback-on-the-recent-fusil-fuzzing-campaign-of-cpython/91737

I'm writing a little tech report on the effort, and having some data about whether it's considered useful, a nuisance, impactful, low value etc. would make it much more interesting.

Please boost for visibility :)

Who still writes Python 2.7 code in the year of the Lord 2025? Well, I did, to help a client remove obstacles for upgrading to Python 3.

This was a journey backward in time - in reverse order performing the steps you'd make, to upgrade from Python 2 to Python 3.

How do you create a modern add-on for Plone 6, that is also backward compatible with Plone 4.3 on #Python 2.7 with Archetypes?

In this blog post, I’ll explain the technical details of creating collective.collabora, making it work in many #Plone versions, while also providing continuous integration and 100% test coverage.

A couple of little known bits of Python history: Python's initial local package building client tools (distutils) were born in the late 20th century as a common build backend for Linux distro packaging of Python projects and its initial transitive dependency management tools (setuptools) were born in the early 21st as a plugin management tool for an open source Exchange competitor (OSAF's Chandler project). Evolving from those foundations has been... interesting :) #python

I've had a Kaggle account for years, but I only used it to pull down datasets to try out with my schemaless ORM-lite #Python package littetable. This past week I discovered you can also host Jupyter notebooks there, so I created several demo notebooks - fun! Here are a few links:

The TIOBE index is crude, but it's exciting to see #Python continuing to shine: https://www.tiobe.com/tiobe-index/

Too bad about the simplistic and misleading summary: "[Python] is interpreted and thus prone to unexpected run-time errors."

Even though I like the language, sometimes I think #Rust is somehow like #Python for masochists.

Even though I like the language, sometimes I think #Rust is somehow like #Python for masochists.

Another tidbit from the report I'm writing about #fusil:

The 52 issues filled correspond roughly to 30% of all the crashes (issues with "type-crash" label) and 2% of all issues (features requests, bugs and invalid issues) reported in the #CPython issue tracker during the six months period covered by the report.

Hits and new issues don't appear at a steady pace. It seems that there are long periods of no or nearly no new issues, followed by rapid finding of new results.

#fuzzing #Python

and, dear reader, at the very top of the page, consuming more than 100% of the space above the fold, on the page for the #Python hashtag, was this toot https://infosec.exchange/@gtronix/114473986225249233

so I thought to myself, I should try to use some of these tools at my disposal, I care about my friends and the folks I'm a fan of whomst I follow, but a lot of them are posting about doom more or less nonstop, maybe I should have a look at, like, the #python hashtag to get away from the fascist terrorism and the infosec breach nightmares and the AI slop and so on, maybe I can post some stuff that *others* can riff on if there's something good there

First, there is no such thing as "#ArtificialIntelligence". It's not artificial and it isn't intelligentce. As a pursuit, it is quite real, and what it produces is not intelligence, but detailed models based on huge amounts of related archived data. The important word here is "model". So every time you see output from #Gemini or #ChatGPT, put in your mind that it is a MODEL of a paragraph on a topic, a MODEL of a picture of a sparrow on a pear, a MODEL of #python code. 2/

You know how sometimes a little hobby side-project can get a bit out of hand? An unexpected performance regression on speed.python.org that only showed up on GCC 5 (and 7) led me to set up more rigorous tracking of Python performance when using different compilers. I'm still backfilling data but I think it's pretty awesome to see how much, and how consistently, free-threaded Python performance has improved since 3.13:

#Python #CPython #Python314 #release

You know how sometimes a little hobby side-project can get a bit out of hand? An unexpected performance regression on speed.python.org that only showed up on GCC 5 (and 7) led me to set up more rigorous tracking of Python performance when using different compilers. I'm still backfilling data but I think it's pretty awesome to see how much, and how consistently, free-threaded Python performance has improved since 3.13:

#Fusil works by generating source files with random calls, using interesting arguments, then monitoring their execution and output. It usually finds crashes resulting from the processing of invalid objects and unexpected call patterns.

Fusil was created by @vstinner.

Features added by me include running generated code in parallel threads, testing class instances in addition to classes and functions, and using new interesting objects/values as inputs.

https://github.com/issues/created?q=is%3Aissue%20author%3Adevdanzin%20-repo%3Adevdanzin%2Ffusil%20fusil%20%20sort%3Acreated-asc

#Python #fuzzing

Writing about #fusil. Some bits:

Fuzzing #CPython with fusil shows it to be a valuable tool for finding and fixing crashers. It started in October 2024 and is ongoing, using free tier cloud instances and personal computers.

Results:
- Fuzzing time: > 25.000 hours
- Fuzzing sessions: > 1.000.000
- Hits: > 50.000
- Issues filled: 52

The original design of fusil makes it well-suited for fuzzing CPython, finding both deep, relevant bugs as well as shallow, low value crashes.

I was attracted to Python back in 1998 because made programming so much simpler, and I recaptured the joy of quick iterative development.

I was attracted to Rust even though I knew it would challenge me, and in return stretch my brain to become better and offer things other languages couldn't offer -- low level control to get performance combined with the memory safety Python gave me.

I felt empowered by both.

Southern California #PyLadies and #Python folks, I need your help!

I'm in the planning stages of forming a PyLadies chapter based in the San Gabriel Valley (that's Pasadena, Monrovia, Arcadia, but could also include Glendale and Burbank, and many more communities on the east side of Los Angeles).

Before I submit requests and get the ball rolling, I'd like to find a third person who's interested in signing on as an organizer. Initially there won't be much responsibility beyond getting the word out and helping to decide what our first events will be. It's a great opportunity for someone looking for leadership experience in a volunteer setting.

If you're interested, feel free to reach out to me here, or at my email address on mechanicalgirl.com, or even on the PyLadies or SoCal Python Slack spaces.

Relatively obscure #Python standards question:

In PEP 257¹ and PEP 258², "attribute docstrings" are defined as:

«A string literal immediately following an assignment statement»

Python's abstract syntax trees do not represent blank lines, it is as if they were deleted in the input source.

Note that PEP 258 does also explicitly mention that using blank lines to visually separate documented attributes.

Question: how many blank lines is the specification allowing between the assignment and the string literal? Is the specification talking about abstract or concrete syntax?

Someone asked about a deployment that failed using django-simple-deploy. The root cause was that their requirements.txt file had a UTF-16 encoding.

I'm currently parsing requirements.txt (when present) with path.read_text(), with no args. I could catch the UnicodeDecodeException, but is that worth supporting?

Is a UTF-16 encoded requirements file just going to cause problems for them down the road? I've never run into this before, and have no idea how common it is.

https://blog.trailofbits.com/2025/05/01/making-pypis-test-suite-81-faster/

this is some of my favorite kind of work: faster test suites means that developers run tests locally more often, and are less hesitant to add new tests (especially parametric ones). another great example of security and performance/reliability engineering dovetailing.

If so, let me know and I will run it, or help you to get it running.

The fuzzer is #fusil, which generates random code calling into your functions and methods. It's useful to check for crashes on invalid inputs or unexpected call patterns.

It has found about 50 crashes in #CPython, 20 in #PyPy, 6 in #Numpy etc.

I was looking for an alternative to classic shell scripts, so I timed a Hello World program in different languages for fun. I thought you might want to know:

1 ms - #Bash
1 ms - #Perl
12 ms - #Python
33 ms - #Go (shebang calling `go run`)
38 ms - #C (shebang compiling to temporary file)
61 ms - #Rust (shebang compiling to temporary file)

Needless to say that this is a highly unfair and silly comparison. It's still interesting, though.

If an error in your #Python program seems impossible, double-check that you haven't edited the source after starting the program. Tracebacks re-read the source files to show the lines of code, so they can show you edited lines that aren't what you are running.

@MaggieFero #NBPy

Because I do a fair amount of frontend work but think most frontend frameworks are overkill, I use #HTMX and #alpinejs a lot. And @glyph's #NBPy talk made me think about what a #PyScript package that combines both and provides #python handles to both would look like.

What could I build if I had a drop-in #django package that gave me all the interaction I wanted while writing python code?

A while ago, I caught the news that former #Python release manager, @swearyanthony is in the ICU in a critical condition with an unclear prognosis. I'm a Python person because I had the fortune to meet Anthony at the right time, and I'll be keeping him in my thoughts as this year's #NBPy unfolds.

I assume this happened because I have `dynamic = ["version"]` in my `pyproject.toml`, with the version computed by `versioningit` as a function of the current commit/tag, date, and working tree state.

Both `pip` and `setuptools` are resolving that, but with a delay between the two and if that delay happens to cross a date boundary, kaboom?

That makes sense to me but also seems like a flaw for dynamic versioning writ large…

Any #Python folks who have seen¹ this discrepancy in version between integration frontend and build backend have input? Is there some way to untie that TOCTOU-ish knot?

¹ no speculation, please, I am soliciting direct experience. I can generate plenty of speculation by myself.

Do you maintain or contribute to a #Python package that includes a C extension? Would you like to run a fuzzer against it?

If so, let me know and I will run it, or help you to get it running.

The fuzzer is #fusil, which generates random code calling into your functions and methods. It's useful to check for crashes on invalid inputs or unexpected call patterns.

It has found about 50 crashes in #CPython, 20 in #PyPy, 6 in #Numpy etc.

Python devs, I'd like your opinion on putting extensive business logic in `__init__.py`.

It makes me feel a bit icky because it often leads to unavoidable imports. Sometimes, it gets mixed with import shortcut definitions and other administrative stuff.

Personally, I like my inits to be empty, as much as possible.

But maybe that is just me being silly.

So, what do you think of business logic in `__init__.py`?

#Python

Time to use the screenshot of a toot from @evacide in my keynote at #PyConLT tomorrow #python #community #ethics

Hey guys, I'm not so #newhere but I wanted to change my username, kind of reboot of my cortex implant.

introduction
Here are some stuff about me:

• Linux user since 13th July 2015 ;
• #scifi is my passion;
• I may be #hobbit -ing sometimes;
• Kopimism follower;
• I just started to learn #programming with #python #bash #cpp #rust

What is HardTech?
Hardtech is a #scifi project I have: a scifi documentation website; a website that describes in details fictional technologies. A kind of user manual for a spacecraft/space station.
The aesthetics are rusty, unsafe, industrial. You must see wires in the spaceships/space station, you must not feel safe when you're on board. Main colors are various orange and black.

Hardtech is LowTech

Why? Because HardTech needs to know technologies in details to make them understandable for other people, but needs to stay technical and cryptic enough to keep the sense of wonder.

I hope you will enjoy.

Different languages are good at different things.

People have mocked #Perl for being a "write only" language, but I feel like the Perl community should take pride and own that slur - you don't need to constantly read and re-read and re-re-read (and edit) the Perl code, because it just keeps working.

Not so with #Python. Python will deprecate your shit and you will NEED to re-read that code so you can make pointless edits to keep it working.

I'm adding resources for future reading for mine and Marie's #Python #packaging tutorial for #PyConUS, and I realised that I don't know any good #pytest tutorials for beginners. Does anyone have any reccommendations?

Roughly one day a week lately, I have been working with a friend to reboot some of the many https://pagekite.net things that had stalled while I had other priorities. It's been great!

When we started working together, she was a bit baffled at my complaints about the upgrade treadmill and the #Python community's wilful lack of fucks to give about long term stability.

It didn't take long, maybe 4-5 sessions, before she began to vehemently understand what I was moaning about...

Some little-used #Python regular expression features that *aren't* confusing punctuation! https://nedbatchelder.com/blog/202504/regex_affordances.html

Okay, yeah, so, that method was BS for two reasons: I'm formatting the milliseconds from the log record, but the rest of the timestamp from "now" (lol, ouch) – but also, the underlying problem is using time.strftime (like the base class) instead of the more modern datetime.datetime.strftime. Because the latter actually _does_ have a format string placeholder for microseconds (not milliseconds though).

So, after a bit of iteration, I think I'll be going with this one:

#Python #logging

Python: *has very flexible logging system*

also Python: *has no format string placeholder for fractional seconds*

me, wanting a ISO 8601 compatible timestamp with milliseconds in his logs:

Tried some 'vibe coding' today. Hmm. On the plus side I found out about a #python package I didn't know - https://pandas-market-calendars.readthedocs.io/en/latest/ - on the minus side it completely hallucinated a method that has never existed. So on balance probably neutral?

I also maintain a #Python convenience library for writing #macOS applications, QuickMacApp. I did a new release of it recently to add the new notifications API, and there's finally some documentation on the web: https://pypi.org/project/quickmacapp/2025.4.15/

Did you know that I maintain a #Python library for writing idiomatic, deterministic finite-state automata, where the inputs are method calls and the outputs are return values? Today there's a new release of it, with some minor updates and to officially add 3.13 to the support matrix (although it did work fine before): https://pypi.org/project/Automat/25.4.16/

A quick #Python example of why you should only evaluate boolean expressions in a boolean context:

Since an empty list evaluates to `False`, people like to write code like this:

async def get_things() -> list[Thing]:
...

things = get_things()
if things:
...

The above code will happily type check even though it is severely bugged. If you are properly explicit about the condition, the type checker will alert you to the error:

things = get_things()
if len(things) > 0:

Just released: Pillow 11.2.1 🚀

There was meant to be a 11.2.0 on 1st April, but we put too much good stuff in the wheels and hit the @pypi.org project limit before it could all be uploaded. That was yanked and now deleted and 11.2.1 is back to normal size.

We'll try and put the good stuff back for 11.3.0 on 1st July but take up less space.

#Python #release #Pillow

🐍🚀🎨 Pillow 11.2.1 has been released!

What happened to 11.2.0?

Two things: we added AVIF support which made the wheels much bigger, and we hit the PyPI project size limit before the release could be fully updated.

11.2.1 instead has AVIF support but needs to be built from source. We'll look into including AVIF in wheels in a future release so that the size doesn't increase so much.

This release also adds Arrow support and more:

Ugh, Python got over 500 #GSoC applications this year and so many of them are absolutely trash, didn't follow any of the instructions. Most years about half of our applications are like this. But usually we have a lot fewer applicants and the submissions were blank files not plausible AI nonsense.

no, Astra, making an async version of jinja/jinjax is not a reasonable use of my time.

I've spent the afternoon writing an EPUB format writer for @novelwriter. It now has all the meta data XML files and can dump raw text of the novel without text formatting, so that's very good progress.

Next is of course to make it also format the text itself for the pages.

It's an interesting format to work with, and like ODT and DOCX is rather messy. Like DOCX, I get the feeling it's been modified a lot too.

#Python folks: if you want an interactive debugger, what do you use, and how do you set it up? Particularly on unfamiliar projects with something like tox/nox/Just which gets between you and the running process. Bonus points if you have a functioning #Emacs integration.

In principle I love the idea of interactive debuggers. In practice I have been burned so many times by configuration, path, and terminal interaction issues that I have an almost instinctual recoil from anything based on pdb.

this makes me really happy: over 1/6th of the top (by download) Python projects are producing attestations!

that's a meteoric adoption rate, given that we only enabled attestation upload support on PyPI ~5 months ago!

Package Manager for Markdown

I'm working on a project that is intended to encourage folk to make markdown text files which can be bundled together in different bundles of text files using a package manager.

Question for coders; Which package manager would you suggest I use?

Main criterias (in order) are:

1. Easy for someone with basic command line skills to edit the file and update version numbers and add additional packages.

2. All being equal, more commonly and easy to setup is preferred.

#Markdown #CommonMark #PackageManager #Programming #Dev
#NPM #RubyGems #Cargo #PickingAMastodonInstance
#Ruby #Python #Rust #Javascript #NodeJs #Lisp #CommonGuide

PEP 751 has been accepted! https://peps.python.org/pep-0751/

This means #Python now has a lock file standard that can act as an export target for all tools that can create some sort of lock file. And for some tools the format can act as their primary lock file format as well instead of some proprietary format.

I took part in #PyWeek 39 over the weekend and made a game in #PyScript. It's a single-tap rhythm game. Should work on any desktop browser and most new phones. It was a fun challenge to make a game where the realtime music sync is so important. You want to let people tap a little too late and still have the game allow it. You want it to be playable with Bluetooth headphones and keyboards that add a lot of latency.

So, just wondering: what is a decent European alternative for payment handling like #Stripe? (It must support both single payments and monthly subscriptions.)

I've been out of the loop and I am sure there are people with experience here.

Preferably one with a matured API (and a Python library would be a nice bonus).

Thanks in advance for any suggestions.

Was ziemlich cool an Pip ist:
Man kann Python-Packages direkt aus einem Git-Repo installieren, ohne dass das Package auf PyPi existiert.

Das geht so:
pip install <package_name>@git+<repository_url>

Das währe dann z.B. der Installationsbefehl für ein Modul, an dem ich gerade bastle:

@glyph
It’s really difficult to filter it all out and maintain a healthy mental attitude right now. I still end most days with a stress stomach ache. But what IS helping is reconnecting with community. This *waves around at all the #python folks* is my biggest community, and I’m trying to talk to as many people as I can every day, catch up on Zoom when I can, see people in person when I can. And I’m an introvert, but somehow connecting takes some of the fear away.

I am in urgent job search mode, so I'm gonna throw this out here and see if anything comes of it.

I am a #Canadian, fluent in both #English and #French. I have experience with several programming languages. My strongest proficiency is with #Haskell and #C. I also have a reasonable grasp of #HTML, #JavaScript, #SQL, #Python, #Lua, #Linux system administration, #bash scripting, #Perl, #AWK, some #Lisp (common, scheme, and emacs), and probably several others I've forgotten to mention.

I am not necessarily looking for something in tech. I just need something stable. I have done everything from software development, to customer support, to factory work, though my current circumstances make in-person work more difficult than remote work. I have been regarded as a hard worker in every job I have ever held.

Well, I had a minor stumble releasing #pyparsing 3.2.2 this past weekend, with a bug (Issue #600) that snuck past several thousand unit tests. So I added 1 new test with several hundred new cases that caught that bug, then fixed it (and a sibling bug 10 lines of code away from the first one). Great immediate notice of failing CI pipelines from diligent users, I was able to get 3.2.3 out with the fix Monday evening. And all's right with the world again (the #Python world, anyway).

GitHub Actions now supports free-threaded Python!

I wrote up how to add it your workflows so you can start testing free-threaded Python 3.13 and 3.14 with either actions/setup-python or actions/setup-uv.

Cheers, #CreativeCoding friends!
I'm going to try out something, let's see what happens... next Saturday (2025-03-29) and possibly on some other Saturdays after that. I'm going to host an online space where I show something about Creative Coding with #Python and #py5. I'm calling it "Python Creative Coding Free Walking Tour". I'll also do some "py5 Office Hours", Q&A and on-boarding.

It will be free, and I'll accept donations, just like the free walking tour we have showing off nice spots of São Paulo for tourists. I hope it will be even better than that: as I studied architecture I find the tour guide's explanations a bit over the top and sometimes missing the point, but maybe mine will also be an over the top creative coding tour, who knows? you'll have to judge by yourselves.

The first, "walking tour" part will be from 11:00AM BRT (UCT -3) to 12:00 and then, the second, "office hours" part, will be from 12:15 to 13:00, when people will be able to ask me anything about py5 and I'll try to answer to the best of my knowledge, it will also be an opportunity to get help setting up your tools/environment in order to take your first steps drawing with code.

That's it for now — trying to take it easy on the self-promo for the moment because I think I'm getting close to actually launching one of these apps for real, and then I'll get REAL obnoxious. Maybe I'll even remember one of those hashtags like #python or #opensource next time

@mrchrisadams In 2018, #python was chosen "unofficially" to be taught to all pupils in France (at the Lycée level, for 16 to 18 years old). In 2020 it became official, and not only for mathematics. I guess we're reaping some rewards now !

I have a code section where I must select one of 4 pyparsing classes based on the settings of 2 arguments - whether to match a string with or without case sensitivity, and as or as not a keyword.

See examples below - I had hoped to make this a poll, but apparently my client will only permit images _or_ polling :( So respond in replies please. #python

#Python dicts are ordered (as of 3.7) by insertion order. But Sets are not. Seems ilke an oversight...?

There are 102 comments on this suggestion to add an OrderedSet but why not just enhance Set to work like dict keys? (A lot of the comments aren't helpful either because they just say 'ah you rube, sets aren't ordered' which is appeal to mathematical definition instead of how people use them irl)

Just released: pypistats 1.9.0 🚀

pypistats is CLI to show download stats from PyPI

https://pypi.org/project/pypistats/1.9.0/

* Replace deprecated classifier with licence expression (PEP 639)
* Remove GitHub attestation, uses PyPI attestations instead (PEP 740)
* Add input validation for total and fix --monthly with no mirror
* Update docs for recent command

#Python #CLI #pypistats #release

Pyparsing 3.2.2 cleans up a formerly internal-only utility method make_compressed_re(), and makes it part of the public API. Given a list of strings, it generates a regex to match those strings and only those (so no cheating like ".*").

Here are before/after expressions for matching chemical symbols.

#python #pyparsing #regex

It's probably nice that `psycopg2` decided to go with `%s` as the interpolator for prepared statements (even when one would expect other types like `%d`), but I have to wonder why it only supports those and not `?` like many other db interfaces, including the builtin `sqlite`. Does anyone know?

It's also zoomed in and shows fewer releases than before. There's another chart further down the page showing all of 2.6 to 3.14. And the wording in the status key has been refreshed to make it clearer.

@pycharm has a handy feature like adding a name import by ⌥+Enter on an underlined unknown name. If you use it and suffer from the fact that the name is added to the existing "from" import at the end, and not in alphabetical order, as linters want, then this option will solve your problem. It is located in Editor → Code Style → #python → Imports.

If your test suite can run on #Python 3.14, and you use branch coverage measurement, please get Python 3.14.0a6 and coverage․py 7.7.0 and let me know how the speed compares to older versions! It will be faster!
