If you don't maintain a library where your users would benefit from delayed string interpolation or automatic pre-processing of inputs, then you don't need to think about t-strings until a library tells you to use one.

#Python

Even still, we’re raising the flag early: the PSF has only ~6 months of runway and needs your support to sustain essential #Python & #PyPI infrastructure, #PyConUS, and, hopefully, to reopen our Grants Program.

Among them, the tiny but mighty PSF team. Now’s the time to invest to enable the PSF to continue its mission.

So if your org runs on Python, please consider sponsoring the PSF: https://www.python.org/psf/sponsorship/

If Python shaped your career, consider becoming a Supporting Member: https://www.python.org/psf/membership/supporting/

And never hesitate to share your “why” via social media, how Python helped you, spread the word.

I’m in. Join me!

#Python #OpenSource #PSF (2/2)

Did you know @ThePSF is a charity that runs on a budget that is a vanishingly small proportion of the money that Python-using corporations make, but we still put on PyCon US, run PyPI, and (try to) fund grants that support Python events all around the world.

Changes in the tech and politicial landscape make it ever harder to fund the essential work we do. If #Python is part of your life, read this post that connects the dots, and consider donating or sponsoring our work: https://pyfound.blogspot.com/2025/10/connecting-the-dots.html

The Steering Council has accepted PEP 810 (explicit lazy imports) for Python 3.15!

https://discuss.python.org/t/pep-810-explicit-lazy-imports/104131/466

#Python #PEP810 #LazyImports #lazy #Python315

The #python library #aiohttp uses #yarl for URLs internally, and yarl normalizes URLs by default. It silently decodes some %-encoded characters in the query string that do not strictly need to be encoded.

Sounds harmless, but it isn't. Changing the URL breaks any protocol that signs important aspects of a HTTP request for security.

Took me a while to find this bug. I usually expect an HTTP client library to not silently manipulate the URLs before sending a request. Smarter is not always better

@cargot_robbie I've posted an updated demo video of my QGIS "Walk Potential" plugin and published the code to Gitlab.

Hey hive mind - I'm keen to start a PhD and move toward academia, and am thinking about potential research topics. I'm an experienced structural #engineer and want to transition toward #sustainability as much as I can. But I'm not sure what that means for viable #research areas...

I have particular expertise in mechanics of #materials, software development ( #Python and #JavaScript), and cold-formed steel / #buckling of thin-walled structures.

Anyone out there have any suggestions for specific topics or general directions?

Donation of $314.16 plus the 3% fee.

To prioritize sidewalk funding, it's useful to know where there's pedestrian demand. Walk Potential calculates this by analyzing how many of 20 different categories of amenities are within a 10-minute walk.

I'm in the process of releasing Walk Potential as a plugin for the QGIS, a free desktop QGIS app. This will make it easier for people to try it out and use.

Cursed #Python on #Windows fact:

It is possible to create a file on a system where Long Paths are enabled that is entirely valid, but which `open()` cannot read.

I don't think I've ever stumbled on it, but each "component" (thingy-between-backslashes) in a Windows path is separately limited, usually to 255 bytes.

It is definitely possible to make a file with a filename longer than this through the GUI (i.e. copy 'a'*1024 onto the clipboard, "New File", and paste), but I don't know how this works in the #Win32 API. Maybe the "real" component is the equivalent "short" name and there's some metadata storing the pretty version.

#python

@sjoaquim true, that makes it much clearer.
I think this is left from my iterations, I had started with a tuple `[False, e]` and `[True, value]` kinda structure ...
Is this non-exception style (or functional) something common in the #python world? I rarely see it in the #django sphere (I am in).
In the #JS world it is much more common, even though fought over a lot ;).

What are the #python people's opinions about having classes like

@dataclass(frozen=True)
class OkResult:
value: int
error: None = None

@dataclass(frozen=True)
class ErrorResult:
value: int = -1
error: ErrorDict

used e.g. as return value
`return ErrorResult(error=e)`
instead of
`return False, e`
or even
`raise Exception(e)`

Is this a thing in the python world?
I try to avoid exception bubbling.
Looks #functional, though I am more keen about easy to use/test code

Update: a few hours before the deadline, we reached the goal!!!

This week, the #Python Software Foundation rejected a $1.5MM NSF grant, due to a requirement that the PSF abandon diversity work.

So I joined forces with Python folks (@offby1, @petrillic, @amethyst) and we're matching up to $12,000 of donations to the PSF. 🧵

It's hard not to see the huge upswell of community support for #Python and the @ThePSF and not feel sadly vindicated in recent criticism of the state of the #Ruby community.

Python is unbelievably popular, shed its outdated BDFL model years ago and built better governance, and has found broad application across dozens of vertical industries.

Ruby barely holds above legacy language water (Objective-C, Groovy), offers one big (fashy) framework, and governance is objectively in disarray.

Based on @lorenipsum's post about python being all backbone (software) and @ThePSF's refusal to roll over. I give you my sticker idea¹

Notes: This confluence of puns tickles me. supine sounding like serpentine and spine and being upside-down, aforementioned backbone, nod to "don't tred on me" and *maybe* a wink to Tiresias and hitting snakes.

OK back to code.

#python #dei #psf #sticker #graphic #logo #design #satire

A python logo coloured two headed undulating snake with cute little eyes. The blue side on the left says "all spine" and the left side upside down says "never supine"

While in some ways the decision was tough, knowing the #Python community would have our backs made it easier. We want to thank you deeply for the words of support across many platforms- but also your actions.

Hey #PSF, I am a supporting member and will also donate because you stood up and showed principles matter.

But would you please offer other methods of funding and donations besides PayPal or check? I personally don't give PayPal my business and wish you felt the same. I'll send a check instead but it makes it more difficult for both of us.

The Python Software Foundation (PSF) was offered a National Science Foundation (NSF) grant only on the condition that they stop all Diversity, Equity, and Inclusion (DEI) efforts at the PSF, and open themselves up to having previous grants revoked.

I'm glad that the PSF turned down the grant with these conditions, even though it would have helped the Python ecosystem - and overall software supply chains - a lot.

I need to extract certain information from a bunch of images. I'm a Python developer, but know little about this niche. Can somebody suggest particular toolkits to start with?

The problem: The placement of flippers on pinball machines has a rich history. There are thousands of different pinball machines. I would like to identify broad trends and turning points. So I'd like to be able to process photos like this in bulk, spot the flippers, and record their locations relative to the rest of the playfield: https://www.ipdb.org/showpic.pl?id=20&picno=38587

I know how to get the raw data (lists of pinball machines, collection of images) but the part I don't know how to tackle is the image processing (selection of best playfield image, compensating for photographer variation, finding the flippers, extracting their position and angle).

If you've done something like this before, what has worked for you? #pinball #python

They say "don't read the comments" but I think the ratio of good vs bad comments in this thread makes it very, very worthwhile.

Also, the *reach* has been amazing. I've seen reposts from people I follow for very non-Python reasons (not mutuals!), who as far as I know have never posted or commented on Python before. ❤️

As I mentioned to @lorenipsum , it's great to not feel so alone in this.

#Python #ThePSF

I have nothing but respect and sympathy for @ThePSF in their decision to withdraw from the NSF grant program in order not to compromise on their mission to keep #Python a diverse and welcoming open source community.

It's hard as hell to turn down that kind of money.

So, here's my .02c for it, metaphorically. I'll personally make a $1000 donation to help fill in that gap. There are certainly 1500 of us who can spare that much, in the global python community. Who's with me?
