Spent basically the entire day (except for the mandatory walk) fighting with Python’s type hints. But, the result is that my widget toolkit now passes mypy --strict.

I really, really don’t want to write larger pieces of software without static typing anymore. With dynamic typing, you must test every code path in your program to catch even the most basic errors. pylint helps a bit (doesn’t need type hints), but that’s really not enough.

Also, somewhere along the way, I picked up a very bad (Python) programming style. (Actually, I know exactly where I picked that up, but I don’t want to point the finger now.) This style makes heavy use of dicts and tuples instead of proper classes. That works for small scripts, but it very quickly turns into an absolute mess once the program grows. Prime example: jenny. 😩

I have a love-hate relationship with Python’s type hints, because they are meaningless at runtime, so they can be utterly misleading. I’m beginning to like them as an additional safety-net, though.

(But really, if correctness is the goal, you either need to invest a ton of time to get 100% test coverage – or don’t use Python.)

Yikes. https://adamj.eu/tech/2021/05/13/python-type-hints-how-to-fix-circular-imports/

Pep8 is deprecated, I think

Hmm, I don’t think it is, this still says “Status: Active”: https://peps.python.org/pep-0008/ 🤔

@movq@www.uninformativ.de @prologic@twtxt.net That’s what I like about Go, too. However, every now and then I really dislike the result, e.g. when removing spaces from a column layout. Doesn’t happen often, but when it does, I hate it.

I think I should have a look at Python formatters, too. Pep8 is deprecated, I think, it’s been some time that I looked at it.

Since I used so much Rust during the holidays, I got totally used to rustfmt. I now use similar tools for Python (black and isort).

What have I been doing all these years?! I never want to format code manually again. 🤣😅

Hey folks! We have recently had a wonderful new release of #py5, read about the new 3D trimesh integration feature and the matplotlib TextPath integration.
That release was quickly followed by a release to fix some small issues that surfaced this last week. Please check out py5 0.10.9a1 and join us at https://github.com/py5coding/py5generator/discussions to share your experiences!

And now the event loop is not a simple loop around curses’ getch() anymore but it can wait for events on any file descriptor. Here’s a simple test program that waits for connections on a TCP socket, accepts it, reads a line, sends back a line:

And the scrollbar indicators are working now.

I’ll probably implement timer callbacks using timerfd (even though that’s Linux-only). 🤔

@movq@www.uninformativ.de Yeah, I see. Just crudely checked on my computer, with around 0.013 seconds, Python 2.7 seems a tad faster than Python 3.14’s 0.023 seconds in this little program.

The lazy imports sound not too bad, but I just skimmed over them. There are surprisingly many exceptions, but yeah, no way around them. :-)

The baseline here is about 55 ms for nothing, btw. Python ain’t fast to start up.

$ time python -c 'exit(0)'

real    0m0.055s
user    0m0.046s

@lyse@lyse.isobeef.org

I assume you made the thing load quickly, didn’t you?

That’s the problem with Python. If you have a couple of files to import, it will take time.

I want this to be reasonably fast on my old Intel NUC from 2016 (Celeron N3050 @ 1.60GHz) and I already notice that the program startup takes about 95 ms (or 125 ms when there are no .pyc files yet). That’s still fine, but it shows that I’ll have to be careful and keep this thing very small …

Python 3.14 will bring lazy imports, maybe that can help in some cases.

@prologic@twtxt.net No, that’s Python/curses on Linux. 😅

Well, you girls and guys are making cool things, and I have some progress to show as well. 😅

https://movq.de/v/c0408a80b1/movwin.mp4

Scrolling widgets appears to work now. This is (mostly) Unicode-aware: Note how emojis like “😅” are double-width “characters” and the widget system knows this. It doesn’t try to place a “😅” in a location where there’s only one cell available.

Same goes for that weird “ä” thingie, which is actually “a” followed by U+0308 (a combining diacritic). Python itself thinks of this as two “characters”, but they only occupy one cell on the screen. (Assuming your terminal supports this …)

This library does the heavy Unicode lifting: https://github.com/jquast/wcwidth (Take a look at its implementation to learn how horrible Unicode and human languages are.)

The program itself looks like this, it’s a proper widget hierarchy:

https://movq.de/v/1d155106e2/s.png

(There is no input handling yet, hence some things are hardwired for the moment.)

@movq@www.uninformativ.de Yeah. I had that in my Python implementation and was really missing that.

@lyse@lyse.isobeef.org I’m toying with the idea of making a widget/window system on top of Python’s ncurses. I’ve never really been happy with the existing ones (like urwid, textual, pytermgui, …). I mean, they’re not horrible, it’s mostly the performance that’s bugging me – I don’t want to wait an entire second for a terminal program to start up.

Not sure if I’ll actually see it through, though. Unicode makes this kind of thing extremely hard. 🫤

@kiwu@twtxt.net Assembly is usually the most low-level programming language that you can get. Typical programming languages like Python or Go are a thick layer of abstraction over what the CPU actually does, but with Assembler you get to see it all and you get full control. (With lots of caveats and footnotes. 😅)

I’m interested in the boot process, i.e. what exactly happens when you turn on your computer. In that area, using Assembler is a must, because you really need that fine-grained control here.

#Processing & #py5 tip:
Remember the shapes you put on draw() will be redrawn over and over, and if they don’t move (leaving a trail) you might want to either clean each frame with background(...), or stop the draw loop (noLoop() in Processing or no_loop() in py5), otherwise you kill the anti-aliasing of the lines :D

”`python
import py5

def setup():

py5.size(200, 200)
py5.stroke_weight(2)
# a line that will drawn once only
py5.line(10, 10, 190, 90)  

def draw():

# you could clean the frame here with background(200)
# this other line will be redrawn many times
py5.line(10, 110, 190, 190)

I finished all 12 days of Advent of Code 2025! #AdventOfCode https://adventofcode.com — did it in my own language, mu (Go/Python-ish, dynamic, int/bool/string, no floats/bitwise). Found a VM bug, fixed it, and the self-hosted mu compiler/VM (written in mu, host in Go) carried me through. 🥳

I just completed “Printing Department” - Day 4 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/4 – Again, I’m doing this in mu, a Go(ish) / Python(ish) dynamic langugage that I had to design and build first which has very few builtins and only a handful of types (ints, no flots). 🤣

I just completed “Lobby” - Day 3 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/3 – Again, I’m doing this in mu, a Go(ish) / Python(ish) dynamic langugage that I had to design and build first which has very few builtins and only a handful of types (ints, no flots). 🤣

Ahh that’s because I forgot to call main() at the end of the source file. mu is a bit of a dynamic programming language, mix of Go(ish) and Python(ish).

$ ./bin/mu examples/aoc2025/day1.mu

Using #Python’s #pathlib to compare two repos and get back some missing files from a “recovered” version of a repo (mostly stuff in .gitignore that is handy not to discard right now).

files_a =  {p.relative_to(a) for p in a.rglob('*')
    if '.git' not in str(p)
    if 'cache' not in str(p)
    if 'checkpoint' not in str(p)
}
files_b =  {p.relative_to(b) for p in b.rglob('*')
    if '.git' not in str(p)
    if 'cache' not in str(p)
    if 'checkpoint' not in str(p)

Alright, Advent of Code is over:

It’s been quite the time sink, especially with the DOS games on top, but it was fun. 🥳

In case you’re wondering: All puzzles (except for part 2 of day 10) were doable in Python 1 on SuSE Linux 6.4 and ran in a finite time on the Pentium 133. Puzzle 10/2 might have been doable as well if I had better education. 🤣

It was though year. I finished my PhD, yay! Now, I’m on vacation from my main job, as educator at Sesc, and yesterday I wound down some last freelance work obligations. I really need a break.

I want to rest, make some “prints” of my drawings for friends, go to my local museums and have coffee/tea with friends, and that’s it!

Today we celebrate 18 years of our local #Python users group, #GruPySP, and I’m going to meet friends from #GaroaHackerClube, that’s a great start :)

FWIW, day 03 and day 04 where solved on SuSE Linux 6.4:

https://movq.de/v/faaa3c9567/day03.jpg

https://movq.de/v/faaa3c9567/day04%2Dv3.jpg

Performance really is an issue. Anything is fast on a modern machine with modern Python. But that old stuff, oof, it takes a while … 😅

Should have used C or Java. 🤪 Well, maybe I do have to fall back on that for later puzzles. We’ll see.

Day 2 was pretty tough on my old hardware. Part 1 originally took 16 minutes, then I got it down to 9 seconds – only to realize later that my solution abused some properties of my particular input. A correct solution will probably take about 30 seconds. 🫤

Part 2 took 29 minutes this morning. I wrote an optimized version but haven’t tested it yet. I hope it’ll be under a minute.

Python 1 feels really slow, even compared to Java 1. And these first puzzles weren’t even computationally intensive. We’ll see how far I’ll make it …

https://movq.de/v/f831d98103/day02.jpg

Thinking about doing Advent of Code in my own tiny language mu this year.

mu is:

• Dynamically typed
  
• Lexically scoped with closures
  
• Has a Go-like curly-brace syntax
  
• Built around lists, maps, and first-class functions
  

Key syntax:

• Functions use fn and braces:
  

fn add(a, b) {
    return a + b
}

• Variables use := for declaration and = for assignment:
  

x := 10
x = x + 1

• Control flow includes if / else and while:
  

if x > 5 {
    println("big")
} else {
    println("small")
}

while x < 10 {
    x = x + 1
}

• Lists and maps:
  

nums := [1, 2, 3]
nums[1] = 42

ages := {"alice": 30, "bob": 25}
ages["bob"] = ages["bob"] + 1

Supported types:

• int
  
• bool
  
• string
  
• list
  
• map
  
• fn
  
• nil
  

mu feels like a tiny little Go-ish, Python-ish language — curious to see how far I can get with it for Advent of Code this year. 🎄

Advent of Code 2025 starts tomorrow. 🥳🎄

This year, I’m going to use Python 1 on SuSE Linux 6.4, writing the code on my trusty old Pentium 133 with its 64 MB of RAM. No idea if that old version of Python will be fast enough for later puzzles. We’ll see.

All my newly added test cases failed, that movq thankfully provided in https://git.mills.io/yarnsocial/twtxt.dev/pulls/28#issuecomment-20801 for the draft of the twt hash v2 extension. The first error was easy to see in the diff. The hashes were way too long. You’ve already guessed it, I had cut the hash from the twelfth character towards the end instead of taking the first twelve characters: hash[12:] instead of hash[:12].

After fixing this rookie mistake, the tests still all failed. Hmmm. Did I still cut the wrong twelve characters? :-? I even checked the Go reference implementation in the document itself. But it read basically the same as mine. Strange, what the heck is going on here?

Turns out that my vim replacements to transform the Python code into Go code butchered all the URLs. ;-) The order of operations matters. I first replaced the equals with colons for the subtest struct fields and then wanted to transform the RFC 3339 timestamp strings to time.Date(…) calls. So, I replaced the colons in the time with commas and spaces. Hence, my URLs then also all read https, //example.com/twtxt.txt.

But that was it. All test green. \o/

Windows at work, always a fresh inconvenience:

@movq@www.uninformativ.de I think I now remember having similar problems back then. I’m pretty sure I typically consulted the Qt C++ documentation and only very rarely looked at the Python one. It was easy enough to translate the C++ code to Python.

Yeah, the GIL can be problematic at times. I’m glad it wasn’t an issue for my application.

FTR, I see one (two) issues with PyQt6, sadly:

1. The PyQt6 docs appear to be mostly auto-generated from the C++ docs. And they contain many errors or broken examples (due to the auto-conversion). I found this relatively unpleasent to work with.
   
2. (Until Python finally gets rid of the Global Interpreter Lock properly, it’s not really suited for GUI programs anyway – in my opinion. You can’t offload anything to a second thread, because the whole program is still single-threaded. This would have made my fractal rendering program impossible, for example.)

@movq@www.uninformativ.de Yeah, give it a shot. At worst you know that you have to continue your quest. :-)

Fun fact, during a semester break I was actually a little bored, so I just started reading the Qt documentation. I didn’t plan on using Qt for anything, though. I only looked at the docs because they were on my bucket list for some reason. Qt was probably recommended to me and coming from KDE myself, that was motivation enough to look at the docs just for fun.

The more I read, the more hooked I got. The documentation was extremely well written, something I’ve never seen before. The structure was very well thought out and I got the impression that I understood what the people thought when they actually designed Qt.

A few days in I decided to actually give it a real try. Having never done anything in C++ before, I quickly realized that this endeavor won’t succeed. I simply couldn’t get it going. But I found the Qt bindings for Python, so that was a new boost. And quickly after, I discovered that there were even KDE bindings for Python in my package manager, so I immediately switched to them as that integrated into my KDE desktop even nicer.

I used the Python KDE bindings for one larger project, a planning software for a summer camp that we used several years. It’s main feature was to see who is available to do an activity. In the past, that was done on a large sheet of paper, but people got assigned two activities at the same time or weren’t assigned at all. So, by showing people in yellow (free), green (one activity assigned) and red (overbooked), this sped up and improved the planning process.

Another core feature was to generate personalized time tables (just like back in school) and a dedicated view for the morning meeting on site.

It was extended over the years with all sorts of stuff. E.g. I then implemented a warning if all the custodians of an activitiy with kids were underage to satisfy new the guidelines that there should be somebody of age.

Just before the pandemic I started to even add support for personalized live views on phones or tablets during the planning process (with web sockets, though). This way, people could see their own schedule or independently check at which day an activity takes place etc. For these side quests, they don’t have to check the large matrix on the projector. But the project died there.

Here’s a screenshot from one of the main views: https://lyse.isobeef.org/tmp/k3man.png

This Python+Qt rewrite replaced and improved the Java+Swing predecessor.

@lyse@lyse.isobeef.org Hmmmmmmmmmmmm … guess I should take a look at Qt. 🤔 That’s the one popular toolkit that I’ve never really tried for some reason. I really don’t like C++ (might as well use Rust), so I’ll also use Python.

@movq@www.uninformativ.de Don’t you worry, this was meant as a joke. :-D

There was a time when I thought that Swing was actually really good. But having done some Qt/KDE later, I realized how much better that was. That were the late KDE 3 and early KDE 4 days, though. Not sure how it is today. But back then it felt Trolltech and the KDE folks put a hell lot more thought into their stuff. I was pleasantly surprised how natural it appeared and all the bits played together. Sure, there were the odd ends, but the overall design was a lot better in my opinion.

To be fair, I never used it from C++, always the Python bindings, which were considerably more comfortable (just alone the possibility to specify most attributes right away as kwargs in the constructor instead of calling tons of setters). And QtJambi, the Java binding, was also relatively nice. I never did a real project though, just played around with the latter.

Um dia em que você conta pra alguém sobre a #LiveDePython do @dunossauro@dunossauro nunca é um dia perdido!

#Python #FLOSS #Comunidade

Random musing from a #Python creative coder:

I have this naïve cumbersome thing for dealing with collinear vertices in a polygon (like a vertex in the middle of an edge that doesn’t change the shape of the polygon, and I tried to replace it with some clever #shapely method such as .simplify(…) or .buffer(0) and failed miserably. So I’ll have to keep my home made check-area-every-three-vertices thing for now…

I’m kind of proud of my idea of representing polygons as a set of frozensets of edge vertex pairs because it eliminates all visually equivalent rotations and reverse ordered rotations (that is, if you don’t have pesky collinear vertices).

I was always under the wrong impression that Tkinter is bundled with Python.

It should be. Maybe your distro splits it off. 🤔

@movq@www.uninformativ.de I never programmed with Tkinter myself and it’s been ages that I ran a program which used it. I always thought that it looks awful. But maybe there are nicer themes these days. I just wanted to give the demo python3 -m tkinter a try, but this module doesn’t exist. I was always under the wrong impression that Tkinter is bundled with Python.

@lyse@lyse.isobeef.org Xfce is nice, but it’s also mostly GTK. I don’t really know the answer yet. For now, I’ll just avoid anything that uses GTK4.

For my own programs, I might have a closer look at Tkinter. I was complaining recently that I couldn’t find a good file manager, so it might be an interesting excercise to write one in Python+Tkinter. 🤔 (Or maybe that’s too much work, I don’t know yet.)

#Python is for artists too!

I made some #Python #numpy, #shapely, #trimesh & #py5bot stickers!

PS: I asked the PSF to check if the logos were alright: “you can change the colors and add thing inside, but not change the shape or position of the snakes”. So I had to change my original Python reading club logo…

Salve @elmoneto@elmoneto !

Acho que quero fazer algo parecido com isso aqui, mas a minha incompetência / inexperiência me derruba…

Tenho um geodataframe com praças e parques, e um com massa de vegetação significativa (que peguei no geosampa), queria saber calcular o quanto de cada praça está coberto de vegetação significativa…

https://gis.stackexchange.com/questions/421888/getting-the-percentage-of-how-much-areas-intersects-with-another-using-geopandas

Eu soube fazer um overlay de instersecção, filtrar as com área menor que 100m2 e usar o .explore() pra colorir as massas por área, já fiquei feliz, mas queria mais rsrsrs.

Press play to hear from Marina Zurkow & James Schmitz [@hx2A@mastodon.art] the artists behind ‘The River is a Circle (Times Square Edition)’ - September’s #MidnightMoment, a visual “combination of live data and a matrix of researched information about the Hudson River ecology,” says Zurkow.»
