Python Tip #278 (of 365):

Always include a __init__‍.py file in your Python packages. Even an empty one.

food_utils
├── fruits‍.py
├── __init__‍.py
└── non_fruits‍.py

A package is a directory that Python treats like a module.

When you import the package, the module you get back IS the __init__‍.py file:

>>> import food_utils
>>> food_utils
<module 'food_utils' from '/home/trey/food_utils/__init__‍.py'>

Stars in my galactic star map application, generated randomly with real science and math backing them up. Still working on it.

I need to switch over to a 3D rendering library to minimize data transfer to the client to render the map. Lots, lots, lots, and lots of bugs to fix (I'm up to 120 that I've noticed myself). However, it's coming along nicely.

Yes, I used and will continue to use AI. Please don't comment about how evil it is or how I'm not really doing anything and yada yada yada. I don't care what you think. For those that want to know, I did code this, for the first 5 versions I used no AI, all the math was by hand, but as much as I studied I could not continue. I am a math teacher, not a coder, so I turned to AI to make my vision come true after going as far as I could without. As an amateur developer, I am using my math skills to research and design the algorithms before I hand off to AI for implementation and I review code by hand as well.

This screenshot shows a digital 3D space-mapping interface set against a deep navy-purple background, divided into three main sections: a wireframe viewport on the left, layer controls in the center, and a data card on the right. The primary visualizer depicts a transparent, cuboid volume bounded by thin purple perspective grid lines, filled with a warm amber haze that fades toward the top. Scattered within this volume are hundreds of small, glowing starlight points, predominantly warm white and amber, with a few notable individual stars glowing bright mint green. A scale indicator in the lower-left corner indicates that the volume spans 1.25 sectors, equivalent to 5 parsecs or 16.3 light-years. Positioned directly to the right of the viewport is a vertical column labeled "Slabs," which displays eight stacked buttons with connector lines pointing to horizontal layers inside the 3D cube. These buttons track exploration progress from bottom to top: slab number 50, slab number 51, and slab number 52 are each 100 percent charted, while slab number 53 is approximately 99.62 percent charted, slab number 54 is approximately 82.32 percent charted, and slab number 55 is approximately 19.29 percent charted. The top two layers, slab number 56 and slab number 57, are both listed as "Unknown". The right side of the screen features a dark panel with technical metrics for "Block 76-184 (27 sectors a side)". It details Rings spanning 2052 to 2078, Layers from 149 to 175, Slots in ring 2052 from 4710 to 4735, and Slots in ring 2078 from 5299 to 5327. Total sectors are given as 1.58 times 10 to the 4th power (15,800 sectors), with 1.06 times 10 to the 4th power generated, indicating 67 percent completion. Center coordinates along the x, y, and z axes are negative 6175.9, 5488.1, and 648.0 parsecs, with a distance from the core of 8.26 kiloparsecs, or 2.69 times 10 to the 4th power light-years. The panel concludes with italicized instructions explaining that users can click a slab on the map or select a button beside it, drag or use Shift plus the arrow keys to rotate, right-drag or Shift-drag to move, scroll or pinch to zoom, and select "Reset view" to restore the default perspective.

Fun read, and definitely touches on many of the reasons I prefer #plaintext

With the

> I do not want a financial workbook turned into a pile of numbers that requires me to reconstruct all the formulas manually

I actually *want* much of my data in plain-text (usually CSV or TSV, but sometimes recutils¹ format or remind² format for my calendar or plain-text accounting format ³for my finances) separate from the formulae/processes that operate on it. Sometimes that's an #awk or #python script, for the calendar, remind(1) processes those, and for my finances, ledger(1) or hledger(1) processes those). It brings all those benefits of plain-text to each of those domains, too.

Similarly

> A word processor can handle page layout that would be tedious to reproduce manually.

I've lost countless hours fixing things in Word/LibreOffice/Abiword after moving an image a smidge to the left caused reflow of the entire document, or placing the cursor ended up in bold/italic when I don't expect it to, or modifying "this is what a section-header looks like" got inconsistently applied throughout, or lists got mangled, or some other tweak messed up the entire document.

So I greatly prefer explicit markup that semantically specifies my intent, then lets some other process mung it for output. I've hand-written HTML for decades (it felt like the Reveal Codes functionality in WordPerfect where I started) so it's my go-to, but I'm also cool with Markdown, LaTeX, or DocBook for the same plain-text reasons. And pandoc makes quick work of converting between formats.

One additional benefit of plain-text I didn't see in the article is that it compresses ridiculously well, so whether I manually gzip up files, or my OS uses ZFS giving me transparent compression at the file-system layer, it saves me a great deal of disk-space.

But my conclusion is similar—use plain-text for everything I can where it makes sense gives me longevity of my data (and open formats for the exceptions)

Python Tip #277 (of 365):

For substring checks, use the "in" operator.

Python has a special operator that's meant JUST for checking whether one thing is contained inside another:

>>> part = "Python"
>>> whole = "I enjoy writing Python code."
>>> part in whole
True

More on this:

Make self positional-only when accepting "**kwargs".

... setattr(self, name, value)

Python Tip #275 (of 365):

Pre-fill arguments with functools.partial.

>>> from functools import partial
>>> hex_to_int = partial(int, base=16)
>>> hex_to_int("CAFE")
51966

This is sometimes called "partially evaluating" a function.

I prefer this:
hex_to_int = partial(int, base=16)

Instead of this:
hex_to_int = lambda s: int(s, base=16)

partial is more specialized than "lambda": its only purpose is to call a callable with certain arguments preset.

Following recent tradition, I’m going to add a surprise third release candidate!

It makes sense to include the last-minute lazy-import fixes in 3.15.0 final.

It also makes sense to give time to test them properly, so today’s planned 3.15.0 final is postponed, and I’m going to release a 3.15.0rc3 tomorrow, assuming everything is in place.

And then 3.15.0 final will follow about week later. Exact date to be announced.

RE: https://mas.to/@davidism/117292399049862157

The beginning of the month, when every junk producer's token limit resets, and we get a whole new wave of junk. Turning off PRs helped a lot, but they just started opening "test issue, checking if my API access is broken", or commenting or emailing their patches instead. I really wish I knew how to escape this without turning off community interaction entirely. #python #flask #opensource

I've turned off pull requests from non-members for Flask, Werkzeug, Jinja, and Click this week, and have enjoyed not waking up to a fresh wave of AI junk every morning. I think I'm going to update our contributing guide to say "introduce yourself and how you use the library in chat first if you want to contribute pull requests". Sad that we had to go here, but aside from conference sprints we weren't really getting outside contribution anyway (which is also sad, but that's been the case a lot longer than AI has been around). #python #flask #opensource

It's been 25 years I program in #python and while I understand the name mangling behind the double underscore variables and everything, I still can't find why I would want to use it.

From my point of view this is one historical quirk that will stay forever but shouldn't be used.

The Language Summit was held this year in Kraków, Poland at #EuroPython 2026, with discussions about the future of the Python programming language, including free-threading, #Rust, garbage collectors, type annotations, and namespacing.

Please enjoy and thank you for your patience:

TIL (#Python, #Textual):

1. When styling a particular UI element in generic fashion in the main application, that will impact the same UI element in, for instance, a temporary modal/popup.
2. Apparently the Select and SelectionList UI elements use OptionList under the hood? Styling it caused the first 2 to be confusingly impacted.

Lessons for me:
- Avoid styling generic UI elements, unlike most https://textual.textualize.io/ examples; target the specific ids instead.
- Revisit https://textual.textualize.io/guide/CSS/

Our next meetup is Thursday, Nov 12th at Konttori and it's sponsored by ICEYE.

Python, c'est la vie.
C'est aussi un langage simple à apprendre.
Même sans lire la documentation : https://nondocumentation.garambrogne.net/

Python Tip #272 (of 365):

Do something or return something, but not both.

The list sort method returns None:

>>> numbers = [4, 2, 7, 1, 5]
>>> x = numbers.sort()
>>> print(x)
None
>>> numbers
[1, 2, 4, 5, 7]

The sort method modifies the list IN PLACE: mutating the list is its purpose.

Returning nothing indicates that an action happened.

append, extend, update, and most other mutating methods/functions follow this convention.

Python Tip #273 (of 365):

Avoid needless wrapper functions.

This lambda does nothing but call len:

sorted(words, key=lambda s: len(s))

So pass len itself:

sorted(words, key=len)

I've been working on this for a long while now. It started as a simple script to generate a believable planet for my role playing game. I'm a science and math nerd though, so I wanted to build it with science. I then realized to do that I needed a star, so I built that. Now I've written it to basically generate a segment of a galaxy with sectors, each sector has a density of stars (calculated based on what we observe in our own galaxy) and each star is generated as a system.

DISCLOSURE: While versions 1-4 did not use AI and I coded it entirely by hand, I have been using #AI in version 5. I know this is controversial, but please if you have something negative to say just keep it to yourself. I would never have paid anyone to do this and I am never going to sell this at all.

So langsam fange ich an in #Python reinzukommen. Ich schreibe bestehendes um und muss immer seltener googeln.
Allerdings, dass Blöcke nur durch Einrückung definiert werden finde ich gelinde gesagt bescheiden. Wer sich das ausgedacht hat war kein Freund von Programmierern. Da ist doch totale Grütze.

Today I (Re-)Learned about the `sep` and `end` parameters to Python’s `print`.

`end=‘’` is useful to allow `print`statements not to add a newline. But you can also use it to add something else instead. That makes more sense if you also consider that…

`sep=` allows you to have a separator. For instance, you can print a list vertically with `sep=‘\n’`:

`print(*range(1,10), sep=‘\n’, end=‘’)`

The `*` before `range` expands the content of `range` into multiple arguments to `print`.

And a couple more parameters whose defaults are often OK, but also is good to know about:

`flush` défaults to `False`, but using `print(flush=True)` can help get quicker output from a Python script before waiting for automatic flushing of standard out.

And `file` defaults to `sys.stdout`, but you might want to use something like `print(“Error or debug info”,file=sys.stderr)` to print to the standard error stream, so that if you pipe stdout somewhere else, you still get the stderr messages (or redirect them separately). Of course, you can also have that file-like object passed from elsewhere.

Python Tip #271 (of 365):

Return, don't print.

If your function only seems to "work" in the REPL, it may be printing when it should be RETURNING.

The print function "outputs" to the TERMINAL.

The return statement "outputs" to the code that called your function.

The Python REPL blurs this distinction by printing every non-None return value:

>>> nth_fibonacci(20)
6765

Was that printed, or returned? It's unclear.

I'm looking for work, please boost!

I'm a software engineer with 35 years of experience. I've worked across an unusually wide range of domains: mobile game backends, privacy-preserving data platforms, high-throughput COVID testing infrastructure, email and account systems, e-payment processing, job marketplace systems, and bioinformatics. I pick up new domains quickly and have a history of doing it repeatedly. I understand how to turn business needs into engineering requirements.

I prefer to work remotely but I am open to an in-office job in the Philadelphia area or especially in Philadelphia itself. I've often worked remotely since the 1990s and can operate with minimal supervision. Several of my favorite projects were self-directed: I identified the need, built the thing, and shipped it. My preferred time zone is America/New_York, but I'm flexible.

Some of the many, many technologies I've used are: Python, Perl, TypeScript/JavaScript, Haskell, Go, C, Java. Postgres, MySQL, SQLite. Flask, SQLAlchemy. AWS (Lambda, S3, RDS, SQS, EC2). Docker, Git. Github and Gitlab.

I've also repeatedly picked up new languages and stacks as needed: Haskell for differential privacy research, TypeScript for a 24/7 AWS Lambda system, Flask for my most recent employer. I've become productive with new systems over and over, and I can do it quickly.

I'm a published author (Higher-Order Perl, Morgan Kaufmann), longtime blogger, and conference speaker with a reputation for making complex ideas clear.

I am a U.S. citizen.

Python Tip #266 (of 365):

Reread a file with seek(0).

Try to .read() a file twice, and you'll get nothing the second time:

>>> f = open("my_file.txt")
>>> f‍.read()
'This is my file 👋\nThis is line 2\n'
>>> f‍.read()
''

Python keeps track of your position within a file as you read.

When you're at the end, another read returns an empty string.

The seek method changes that position.

@dolanor No, it's still pip if you want to use pip. Or conda if you want to use conda. But there are other options for people who have a reason to use them or just prefer something different.

If anyone is telling you that you shouldn't be using pip (or, I imagine, conda) anymore, that it's deprecated or disfavored or obsolete or "on its way out" or anything of that nature, they don't know what they're talking about and you shouldn't listen.

Python Tip #265 (of 365):

Use next() to get the first line in a file.

Reading a CSV file and need to skip the first row of headers?

Pass your file object (or csv.reader object) to the built-in next function:

headers = next(reader)

File objects keep track of your position within an open file, so the next time you read (or loop) you'll start up where you left off.

Python Tip #264 (of 365):

Don't use the file readlines method.

Do this:
lines = list(file)

Not this:
lines = file.readlines()

Both give the same list of lines. So why prefer list?

Files are iterables of lines, and list(...) is THE way to say "loop over this iterable and store the results in a new list".

With file.readlines(), it's not as obvious that we're making a list.

Python Tip #260 (of 365):

Bookmark a date format cheat sheet.

Is "%M" month or minute? Is "%H" 12 or 24 hour time? Which one shows a long month name? And a short one?

You COULD memorize all of Python's many date/time format codes, but is that worth it?

It might be worth memorizing the formats you use all the time ("%Y-%m-%d" and "%H:%M:%S" maybe).

But for MOST formats, you can look them up when you need them.

Python Tip #263 (of 365):

Parse messy dates with the third-party dateutil library.

Its parse function guesses the format from the string itself:

>>> from dateutil.parser import parse
>>> parse("September 20, 2026")
datetime.datetime(2026, 9, 20, 0, 0)
>>> parse("20 Sep 2026 14:30")
datetime.datetime(2026, 9, 20, 14, 30)
>>> parse("9/20/26")
datetime.datetime(2026, 9, 20, 0, 0)

I'm a software developer and sysadmin who could really use being #fedihired.

What I'd really like to do is Rust, but once you ignore the dubious scammy stuff, there seems to be nothing out there. Prove me wrong with a counterexample!

I've spent decades fixing Enterprise mudballs mostly written in #Perl. If you've got a crufty legacy system that everybody else is too scared to touch, I'm your man. I love fixing stuff like that.

I've also done commercial #Scala, #Python, #C/#C++, and although I don't usually admit it on my CV but these are now Trying Times when everything is on the table, even #PHP (the longest six months of my life).

Perl naturally leads into Unix system administration and infrastructure. I've built and maintained mail clusters, VoIP systems, network monitoring, DNS management platforms, that sort of thing. If it's non-sexy but something which needs to be done, I'm there.

Available immediately, for contract or permie, onsite in Amsterdam/Randstad or remote to anywhere.

Drop me a private mention or mail peter@mooli.net if you have or know of something.

Python Tip #259 (of 365):

Use datetime arithmetic and comparisons to check whether a date is within a range.

Sputnik launched before the moon landing:

>>> sputnik_launch = datetime(1957, 10, 4)
>>> moon_landing = datetime(1969, 7, 20)
>>> sputnik_launch < moon_landing
True

One datetime is "less than" another when it represents an earlier moment in time.

Python Tip #257 (of 365):

Consider "import datetime as dt".

The fact that the datetime module and the datetime class are spelled the same way is VERY confusing.

You could use a "from" import:

from datetime import datetime

Now datetime means the class.

But if later on you also want the date class, you're importing that name too, and hoping no local date variable ever shadows it. I definitely use the variable name date, so this is a problem for me.

I switched from Python to Guile as my go-to scripting language a few months ago and I've been enjoying it.

Pros:
- Guile is a Scheme
- Guile is slop-free
- Guile is faster than Python
- Guile can easily be embedded in other programs
- Guile easily compiles to WASM with Hoot

Cons:
- Guile's syntax can be less readable
- Guile's ecosystem is smaller
- Guile is less documented

I added `picows` support to the UNICORN Binance WebSocket API.

The benchmark started as a simple library comparison and ended up improving UBWA itself too.

Results:

⚡ up to **2× throughput** on small Binance messages
🧠 about **26% lower average CPU usage**
📨 **138M+ live messages** per implementation
✅ no picows-specific stalls or unrecoverable streams in the 24h soak

`websockets` still remains the default for now.

Why?

Because 24 hours and 138 million messages are strong evidence, but they are not the same as months of production use across many different systems.

So picows is opt-in until broader real-world usage proves it further.

Full benchmark, bugs found, proxy changes and reasoning:

Python Tip #254 (of 365):

Use a module instead of a singleton class.

When you import a module, Python creates a module object. Import it again (even under a different name) and you get THE EXACT SAME OBJECT:

>>> import events
>>> import events as again
>>> again is events
True

So instead of a class that's only ever meant to have one instance:

class EventTracker:
...

tracker = EventTracker()

Last post in the wrapture tracing series: OpenTelemetry export.

One table in the config and the same events that printed a tree feed a backend while the application runs. Requests become SERVER spans named by route, a failing request carries the 500 and the exception the framework swallowed, and one trace id is shared by the files, the outbound headers and the exported spans, so two services join as one trace.

Python Tip #253 (of 365):

Avoid import side effects in your Python modules.

As a general rule, the top level of a module should only DEFINE things. Define functions, classes, constants and any other objects meant to be accessed after import. But don't print, prompt for input, write to files, etc.
