    Brian #1: In memoriam: Michael Foord 1974-2025

    • Guido van Rossum and others
    • We’ve just lost Michael Foord this last weekend.
    • From Guido:
      • “Michael, an original thinker if there ever was one, started the tradition of having Language Summit events at PyCon, IIRC together with Barry Warsaw. He also wrote and contributed the influential mock library. … “
      • “PS. Feel free to post your own (positive) memories of meeting Michael – perhaps his children (10 and 13) will read them when they’re older and this thread might help them remember their father.”
    • I’ve added my memories. I think this is a great (and small) way to honor him.
    • My friend Michael - Nicholas Tolervey
    • After 5 years of trying, I did get an interview with Michael. I wish I’d have gotten that followup.

    Michael #2: Valkey (Redis Replacement)

    • Thanks Calvin HP
    • An open source (BSD) high-performance key/value datastore that supports a variety of workloads such as caching, message queues.
    • Can act as a primary database.
    • Valkey can run as either a standalone daemon or in a cluster, with options for replication and high availability.
    • Valkey natively supports a rich collection of datatypes, including strings, numbers, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs and more.
    • You can operate on data structures in-place with an expressive collection of commands.

    Brian #3: 30 best practices for software development and testing

    • Michael Foord (from 2017)
    • Some gems
      • 1 - YAGNI
      • 6 - Unit tests test to the unit of behavior, not the unit of implementation.
      • 8 - Code is the enemy: It can go wrong, and it needs maintenance. Write less code. Delete code. Don’t write code you don’t need.
      • 15 - The more you have to mock out to test your code, the worse your code is.
      • and so many more …

    Michael #1: LLM Catcher

    • via Pat Decker
    • Large language model diagnostics for python applications and FastAPI applications .
    • Features
      • Exception diagnosis using LLMs (Ollama or OpenAI)
      • Support for local LLMs through Ollama
      • OpenAI integration for cloud-based models
      • Multiple error handling approaches:
        • Function decorators for automatic diagnosis
        • Try/except blocks for manual control
        • Global exception handler for unhandled errors from imported modules
      • Both synchronous and asynchronous APIs
      • Flexible configuration through environment variables or config file

    Brian #2: On PyPI Quarantine process

    • Mike Fiedler
    • Project Lifecycle Status - Quarantine in his "Safety & Security Engineer: First Year in Review post”
    • Some more info now in Project Quarantine
    • Reports of malware in a project kick things off
    • Admins can now place a project in quarantine, allowing it to be unavailable for install, but still around for analysis.
    • New process allows for packages to go back to normal if the report is false.
    • However
      • Since August, the Quarantine feature has been in use, with PyPI Admins marking ~140 reported projects as Quarantined.
      • Of these, only a single project has exited Quarantine, others have been removed.

    Michael #3: RESPX

    • Mock HTTPX with awesome request patterns and response side effects butterfly
    • A simple, yet powerful, utility for mocking out the HTTPX, and HTTP Core, libraries.
    • Start by patching HTTPX, using respx.mock, then add request routes to mock responses.
    • For a neater pytest experience, RESPX includes a respx_mock fixture

    Brian #4: Unpacking kwargs with custom objects

    • Rodrigo
    • A class needs to have
      • a keys() method that returns an iterable.
      • a __getitem__() method for lookup
    • Then double splat ** works on objects of that type.

    Extras

    Brian:

    • A surprising thing about PyPI's BigQuery data - Hugovk
      • Top PyPI Packages (and therefore also Top pytest Plugins) uses a BigQuery dataset
      • Has grabbed 30-day data of 4,000, then 5,000, then 8,000 packages.
      • Turns out 531,022 packages (amount returned when limit set to a million) is the same cost.
      • So…. hoping future updates to these “Top …” pages will have way more data.
    • Also, was planning on recording a Test & Code episode on pytest-cov today, but haven’t yet. Hopefully at least a couple of new episodes this week.
    • Finally updated pythontest.com with BlueSky links on home page and contact page.

    Michael:

    • Follow up from Owen (uv-secure):
      • Thanks for the multiple shout outs! uv-secure just uses the PyPi json API at present to query package vulnerabilities (same as default source for pip audit). I do smash it asynchronously for all dependencies at once... but it still takes a few seconds.

    Brian #1: Terminals & Shells

    • Ghostty is out
      • Started by Mitchel Hashimoto, one of the co-founders of Hashicorp
      • “Ghostty is a terminal emulator that differentiates itself by being fast, feature-rich, and native. While there are many excellent terminal emulators available, they all force you to choose between speed, features, or native UIs. Ghostty provides all three.”
      • Currently for macOS & Linux (Windows planned)
      • Version 1.0.1 released Dec 31, announced in Oct
      • Features: cross-platform, windows, tabs, and splits, Themes, Ligatures, …
      • Shell Integration: Some Ghostty features require integrating with your shell. Ghostty can automatically inject shell integration for bash, zsh, fish, and elvish.
    • Fish is moving to Rust
      • “fish is a smart and user-friendly command line shell with clever features that just work, without needing an advanced degree in bash scriptology.”
      • “fish 4.0 is a big upgrade. It’s got lots of new features to make using the command line easier and more enjoyable, such as more natural key binding and expanded history search. And under the hood, we’ve rebuilt the foundation in Rust.”

    Michael #2: Winloop: An Alternative library for uvloop compatibility with windows

    Brian #3: Ruff & uv

    • Ruff 0.9.0 has a new 2025 style guide
      • f-string formatting improvements
        • Now formats expressions interpolated inside f-string curly braces
        • Quotes normalized according to project config
        • Unnecessary escapes removed
        • Examines interpolated expressions to see if splitting the string over multiple lines is ok
      • Other changes to, but it’s the f-string improvements I’m excited about.
    • Python 3.14.0a3 is out, and available with uv
      • uv python install 3.14 --preview

    Michael #4: uv-secure

    • by Owen Lamont (yes again :) )
    • This tool will scan PyPi dependencies listed in your uv.lock files (or uv generated requirements.txt files) and check for known vulnerabilities listed against those packages and versions in the PyPi json API.
    • I don't intend uv-secure to ever create virtual environments or do dependency resolution - the plan is to leave that all to uv since it does that so well and just target lock files and fully pinned and dependency resolved requirements.txt files).
    • Works “out of the box” with a requirements.txt from uv pip compile.

    Michael #1: dbos-transact-py

    • DBOS Transact is a Python library providing ultra-lightweight durable execution.
    • Durable execution means your program is resilient to any failure.
    • If it is ever interrupted or crashes, all your workflows will automatically resume from the last completed step.
    • Under the hood, DBOS Transact works by storing your program's execution state (which workflows are currently executing and which steps they've completed) in a Postgres database.
    • Incredibly fast, for example 25x faster than AWS Step Functions.

    Brian #2: Typed Python in 2024: Well adopted, yet usability challenges persist

    • Aaron Pollack on Engineering at Meta blog
    • “Overall findings
      • 88% of respondents “Always” or “Often” use Types in their Python code.
      • IDE tooling, documentation, and catching bugs are drivers for the high adoption of types in survey responses,
      • The usability of types and ability to express complex patterns still are challenges that leave some code unchecked.
      • Latency in tooling and lack of types in popular libraries are limiting the effectiveness of type checkers.
      • Inconsistency in type check implementations and poor discoverability of the documentation create friction in onboarding types into a project and seeking help when using the tools. “

      • Seems to be a different survey than the 2023 (current) dev survey. Diff time frame and results. July 29 - Oct 8, 2024

    Michael #3: RightTyper

    • A fast and efficient type assistant for Python, including tensor shape inference

    Brian #4: Lazy self-installing Python scripts with uv

    • Trey Hunner
    • Creating your own ~/bin full of single-file command line scripts is common for *nix folks, still powerful but underutilized on Mac, and trickier but still useful on Windows.
    • Python has been difficult in the past to use for standalone scripts if you need dependencies, but that’s no longer the case with uv.
    • Trey walks through user scripts (*nix and Mac)
      • Using #! for scripts that don’thave dependencies
      • Using #! with uv run --script and /// script for dependencies
      • Discussion about how uv handles that.

    Brian #1: New project to shorten django-admin to django because we are not monsters

    • Jeff Tripplet has created django-cli-no-admin to shorten django-admin to just django.
    • “One of the biggest mysteries in Django is why I have to run django-admin from my terminal instead of just running django. Confusingly, django-admin has nothing to do with Django’s admin app.”
    • Instead of typing things like: django-admin startproject mysite projectname
    • We can type the shorter: django startproject mysite projectname
    • I love this kind of developer speedup / comfort improvements
    • And yes, Jeff wants Django to eventually include this as the default way to run the command line utilities.

    Michael #2: django-unicorn: The magical reactive component framework for Django sparkles

    • Add modern site functionality: Quickly add in simple interactions to regular Django templates without learning a new templating language.
    • Skip the JavaScript build tools
    • No API required: Skip creating a bunch of serializers and just use Django.

    Brian #3: Testing some tidbits

    • Ned Batchelder
    • Different ways to test to see if a string has only 0 or 1 in it.
    • And also, a way to check all the different ways to make sure they work.
    • Fun post, and I learned about
      • cleandoc - a way to strip leading blank space and maintain code block indentation
        • I usually use textwrap.dedent()
      • partition - splitting strings based on a substring
      • Using | to pass imports to eval() - I don't use eval much.
    • However, no pytest!
    • Here’s a way to check all this with pytest:

    Michael #4: The State of Python 2024 article

    1. Python usage with other languages drops as general adoption grows
    2. 41% of Python developers have under 2 years of experience
    3. Python learning expands through diverse channels
    4. The Python 2 vs. 3 divide is in the distant past
    5. Flask, Django, and FastAPI remain top Python web frameworks
    6. Most Python web apps run on hyperscale clouds
    7. Containers over VMs over hardware

    Michael #1: jiter

    • Fast iterable JSON parser.
    • About to be the backend for Pydantic and Logfire.
    • Currently powers OpenAI / ChatGPT (along with Pydantic itself), at least their Python library, maybe more.
    • jiter has three interfaces:
      • JsonValue an enum representing JSON data
      • Jiter an iterator over JSON data
      • PythonParse which parses a JSON string into a Python object
    • jiter-python - This is a standalone version of the JSON parser used in pydantic-core. The recommendation is to only use this package directly if you do not use pydantic

    Brian #2: A new home for python-build-standalone

    Michael #3: moka-py

    • A high performance caching library for Python written in Rust
    • moka-py is a Python binding for the highly efficient Moka caching library written in Rust.
    • This library allows you to leverage the power of Moka's high-performance, feature-rich cache in your Python projects.
    • Features
      • Synchronous Cache: Supports thread-safe, in-memory caching for Python applications.
      • TTL Support: Automatically evicts entries after a configurable time-to-live (TTL).
      • TTI Support: Automatically evicts entries after a configurable time-to-idle (TTI).
      • Size-based Eviction: Automatically removes items when the cache exceeds its size limit using the TinyLFU policy.
      • Concurrency: Optimized for high-performance, concurrent access in multi-threaded environments.

    Brian #4: uv: An In-Depth Guide

    • On SaaS Pegasus blog, so presumably by Cory Zue
    • Good intro to uv
    • Also a nice list of everyday commands
      • Install python: uv python install 3.12
        • I don’t really use this anymore, as uv venv .venv --python 3.12 or uv sync install if necessary
      • create a virtual env: uv venv .venv --python 3.12
      • install stuff: uv pip install django
      • add project dependencies
      • build pinned dependencies
    • Also discussion about adopting the new workflow

    Brian #1: Loop targets

    • Ned Batchelder
    • I don’t think I would have covered this had it not been the surprising opposition to Ned’s code.

    • Here’s the snippet:

      params = { "query": QUERY, "page_size": 100, } *# Get page=0, page=1, page=2, ...* **for** params["page"] in itertools.count(): data = requests.get(SEARCH_URL, params).json() **if** not data["results"]: **break** ...

    • Ned is utilizing the assignment in the for loop to use the value of count() and store it into the params["page"].

    • The article includes another version with a temp variable page_num, which I think the naysayers would prefer.
    • But frankly, I think both are fine. Why not put the value right where you want it?

    Michael #2: asyncstdlib

    • The asyncstdlib library re-implements functions and classes of the Python standard library to make them compatible with async callables, iterables and context managers.
    • It is fully agnostic to async event loops and seamlessly works with asyncio, third-party libraries such as trio, as well as any custom async event loop.
    • Full set of async versions of advantageous standard library helpers, such as zip, map, enumerate, functools.reduce, itertools.tee, itertools.groupby and many others.
    • Safe handling of async iterators to ensure prompt cleanup, as well as various helpers to simplify safely using custom async iterators.
    • Small but powerful toolset to seamlessly integrate existing sync code into async programs and libraries.

    Brian #3: Bagels: TUI Expense Tracker

    • Jax Tam

    • “Bagels expense tracker is a TUI application where you can track and analyse your money flow, with convenience oriented features and a complete interface.

    • Why an expense tracker in the terminal? I found it easier to build a habit and keep an accurate track of my expenses if I do it at the end of the day, instead of on the go. So why not in the terminal where it's fast, and I can keep all my data locally?”

    • Who hasn’t wanted to write their own expense tracker?

    • This implementation is fun for lots of reasons
      • It’s still new and pretty small, so forking it for your own uses should be easy
      • Built on textual is fun
      • install instructions based on uv tool seems to be the new normal:
        • uv tool install --python 3.13 bagels
      • test suite started
      • pretty useful as is, actually
      • Nice that it includes a roadmap of future goals
      • Would be a fun project to help out with for anyone looking for anyone looking for a shiny new codebase to contribute to.

    Michael #4: rloop: An AsyncIO event loop implemented in Rust

    • An AsyncIO event loop implemented in Rust
    • From Giovanni Barillari, Creator of Granian
    • RLoop is an AsyncIO event loop implemented in Rust on top of the mio crate.
    • Disclaimer: This is a work in progress and definitely not ready for production usage.
    • Run asyncio.set_event_loop_policy(rloop.EventLoopPolicy()) and done.
    • Similar to uvloop.

    Brian #2: PyPI now supports digital attestations

    • Dustin Ingram
    • “Attestations provide a verifiable link to an upstream source repository: By signing with the identity of the upstream source repository, such as in the case of an upload of a project built with GitHub Actions, PyPI's support for digital attestations defines a strong and verifiable association between a file on PyPI and the source repository, workflow, and even the commit hash that produced and uploaded the file. Additionally, publishing attestations to a transparency log helps mitigate against both compromise of PyPI and compromise of the projects themselves.”
    • For maintainers
      • If using GH Actions and Trusted Publishing
        • make sure you use pypa/gh-action-pypi-publish, version v1.11.0 or newer

      • Error reporting that is at least as useful as Django's errors.
      • Improved performance over Django's pure Python implementation.

    Brian #4: PEP 639 is now supported by PYPI

    • from Brett Cannon
    • PEP 639 – Improving License Clarity with Better Package Metadata
    • For project metadata, use these fields: license and license-files:

    • Examples license field

      [project] license = "MIT" [project] license = "MIT AND (Apache-2.0 OR BSD-2-clause)" [project] license = "MIT OR GPL-2.0-or-later OR (FSFUL AND BSD-2-Clause)" [project] license = "LicenseRef-Proprietary"

    • Examples of license-files:

      [project] license-files = ["LICEN[CS]E*", "AUTHORS*"] [project] license-files = ["licenses/LICENSE.MIT", "licenses/LICENSE.CC0"] [project] license-files = ["LICENSE.txt", "licenses/*"] [project] license-files = []

      • eembrace plugins vs endorsing plugins.

    Michael #2: futurepool

    • via Pat Decker
    • Takes the concept of multiprocessing Pool to the async/await world.

    • Create a pool then delegate the work:

      async with FuturePool(2) as fp: result = await fp.map(async_pool_fn, range(10))

    • I would LOVE to see something like this in a broader background asyncio worker pool concept.

    • But that concept doesn’t exist in asyncio in Python and that’s a failing of the framework IMO.

    Brian #3: Don't return named tuples in new APIs

    • Brett Cannon
    • First off, I’m grateful for any post that talks about APIs and the API is a module, class, or package API and not a Web/REST API. The term API existed long before the internet.
    • “e.g., get_mouse_position() very likely has a two-item tuple of X and Y coordinates of the screen”
    • “it actually makes your API more complex for both you and your users to use. For you, it doubles the data access API surface for your return type as you have to now support index-based and attribute-based data access forever (or until you choose to break your users and change your return type so it doesn't support both approaches)”
    • “… you probably don't want people doing with your return type, like slicing, iterating over all the items …”
    • Alternatives
      • class
      • dataclass
      • dictionary
      • TypedDict
      • SimpleNamespace
    • “My key point in all of this is to prefer readability and ergonomics over brevity in your code. That means avoiding named tuples except where you are expanding to tweaking an existing API where the named tuple improves over the plain tuple that's already being used.”

    Michael #4: Ziglang: Migrating from AWS to Self-Hosting

    • The Rust Foundation for example, reports that they spent $404,400 on infrastructure costs in 2023.
    • Zig lang has decided to use a single big cloud machine + mirrors

    Michael #1: terminal-tree

    • An experimental filesystem navigator for the terminal, built with Textual
    • Tested in macOS only at this point. Chances are very high it works on Linux. Slightly lower chance (but non-zero) that it works on Windows.
      • Can confirm it works on Linux

    Brian #2: posting: The API client that lives in your terminal

    • Also uses Textual
    • From Darren Burns
    • Interesting that the installation instructions recommends using uv:
      • uv tool install --python 3.12 posting
    • Very cool. Great docs. Beautiful. keyboard centric, but also usable with a mouse.
    • “Fly through your API workflow with an approachable yet powerful keyboard-centric interface. Run it locally or over SSH on remote machines and containers. Save your requests in a readable and version-control friendly format.”
    • Able to save multiple environments
    • Great colors
    • Allows scripting to run Python code before and after requests to prepare headers, set variables, etc.

    Michael #3: Extra, extra, extra

    Brian #4: UV does everything or enough that I'm not sure what else it needs to do

    • Jeff Triplett
    • “UV feels like one of those old infomercials where it solves everything, which is where we have landed in the Python world.”
    • “My favorite feature is that UV can now bootstrap a project to run on a machine that does not previously have Python installed, along with installing any packages your application might require.”
    • Partial list (see Jeff’s post for his complete list)
      • uv pip install replaces pip install
      • uv venv replaces python -m venv
      • uv run, uv tool run, and uv tool install replaces pipx
      • uv build - Build your Python package for pypi
      • uv publish - Upload your Python package to pypi, replacing twine and flit publish

    Brian #1: GitHub action security: zizmor

    • Article: Ned Batchelder
    • zizmor: William Woodruff & others
    • “a new tool to check your GitHub action workflows for security concerns.”
    • Install with cargo or brew, then point it at workflow yml files.
    • It reports security concerns.

    Michael #2: Python is now the top language on GitHub

    • Thanks to Pat Decker for the heads up.
    • A rapidly growing number of developers worldwide
      • This suggests AI isn’t just helping more people learn to write code or build software faster—it’s also attracting and helping more people become developers. First-time open source contributors continue to show wide-scale interest in AI projects. But we aren’t seeing signs that AI has hurt open source with low-quality contributions.
    • Python is now the most used language on GitHub as global open source activity continues to extend beyond traditional software development.
      • The rise in Python usage correlates with large communities of people joining the open source community from across the STEM world rather than the traditional community of software developers.
    • There’s a continued increase in first-time contributors to open source projects. 1.4 million new developers globally joined open source with a majority contributing to commercially backed and generative AI projects.
      • Notably, we did not see a rise in rejected pull requests. This could indicate that quality remains high despite the influx of new contributors.

    Brian #3: Python 3.13, what didn't make the headlines

    • Some pretty cool updates to pdb : the command line Python debugger
      • multiline editing
      • code completion
    • pathlib has a bunch of performance updates
    • python -m venv adds a .gitignore file that auto ignores the venv.
