Michael #1: Talk Python rewritten in Quart Rewrote all of talkpython.fm in Quart (10k lines of code total, 4k changed)Considered FastAPILitestarDjangoHugo Static Site + PythonFlaskDiscussed the multistage upgrade / conversion processAutomating tests for all 1,000 pages 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 newerthat’s itIf not “Support for automatic attestation generation and publication from other Trusted Publisher environments is planned.”“While not recommended, maintainers can also manually generate and publish attestations.”See also PyPI Introduces Digital Attestations to Strengthen Python Package Security by Sarah GoodingAre we PEP 740 yet? Michael #3: Django Rusty Templates by Lily FooteAn experimental reimplementation of Django's templating language in Rust.Goals 100% compatibility of rendered output.Error reporting that is at least as useful as Django's errors.Improved performance over Django's pure Python implementation.

Brian #1: Thoughts on Django’s Core Carlton GibsonGreat discussion on Django and Core vs PluginsSustainability with limited peopleKeeping core smallThe release cycleeembrace plugins vs endorsing plugins. Michael #2: futurepool via Pat DeckerTakes 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 CannonFirst 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 classdataclassdictionaryTypedDictSimpleNamespace“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 Extras Brian: Changing the Python Test community Was started to answer questions for Test & Code listeners years ago. Primarily pytest questionsUsed to be Slack. Then moved to Podia forum. Now I’m trying to work out a Discord solution that is both sustainable and usable.

Michael #1: terminal-tree An experimental filesystem navigator for the terminal, built with TextualTested 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 TextualFrom Darren BurnsInteresting that the installation instructions recommends using uv: uv tool install --python 3.12 postingVery 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.
