Brian #1: mdformat

Suggested by Matthias Schöttle
Last episode Michael covered blacken-docs, and I mentioned it’d be nice to have an autoformatter for text markdown.
Matthias delivered with suggesting mdformat
“Mdformat is an opinionated Markdown formatter that can be used to enforce a consistent style in Markdown files.”
A python project that can be run on the command line.
Uses a style guide I mostly agree with.
- I’m not a huge fan of numbered list items all being “1.”, but that can be turned off with --number, so I’m happy.
- Converts underlined headings to #, ##, etc. headings.
- Lots of other sane conventions.
- The numbering thing is also sane, I just think it also makes the raw markdown hard to read.
Has a plugin system to format code blocks

Michael #2: pre-commit-uv

via Ben Falk
Use uv to create virtual environments and install packages for pre-commit.

Brian #3: PEP 758 and 781

PEP 758 – Allow except and except* expressions without parentheses
- accepted
PEP 781 – Make TYPE_CHECKING a built-in constant
- draft status
Also, PEP Index by Category kinda rocks

Michael #4: Serie: rich git commit graph in your terminal, like magic

While some users prefer to use Git via CLI, they often rely on a GUI or feature-rich TUI to view commit logs.
Others may find git log --graph sufficient.
Goals
- Provide a rich git log --graph experience in the terminal.
- Offer commit graph-centric browsing of Git repositories.

Topics covered in this episode: How to Write a Git Commit Message Caddy Web Server Some new PEPs approved juv Extras Joke Watch on YouTube About the show Sponsored by Posit Connect : pythonbytes.fm/connect Connect with the hosts Michael: @mkennedy@fosstodon.org / @mkennedy.codes (bsky) Brian: @brianokken@fosstodon.org / @brianokken.bsky.social Show: @pythonbytes@fosstodon.org / @pythonbytes.fm (bsky) Join us on YouTube at pythonbytes.fm/live to be part of the audience.

Add your name and email to our friends of the show list , we'll never share it. Brian #1: How to Write a Git Commit Message Chris Beams 7 rules of a great commit message Separate subject from body with a blank line Limit the subject line to 50 characters Capitalize the subject line Do not end the subject line with a period Use the imperative mood in the subject line Wrap the body at 72 characters Use the body to explain what and why vs. how Article also includes Why a good commit message matters Discussion about each of the 7 rules Cool hat tips to other articles on the subject “ Keep in mind: This has all been said before .” Each word is a different link. Michael #2: Caddy Web Server via Fredrik Mellström Like a more modern NGINX Caddy automatically obtains and renews TLS certificates for all your sites. Caddy's native configuration is a JSON document. Even localhost and internal IPs are served with TLS using the intermediate of a fully-automated, self-managed CA that is automatically installed into most local trust stores. Configure multiple Caddy instances with the same storage, and they will automatically coordinate certificate management as a fleet. Production-grade static file server. Brian #3: Some new PEPs approved PEP 770 – Improving measurability of Python packages with Software Bill-of-Materials Accepted for packaging Author: Seth Larson, Sponsor Brett Cannon “This PEP proposes using SBOM documents included in Python packages as a means to improve automated software measurability for Python packages.” PEP 750 – Template Strings Accepted for Python 3.14 Author: Jim Baker, Guido van Rossum, Paul Everitt, Kaudai Aono, Lysandros Nikolaou, Dave Peck “Templates provide developers with access to the string and its interpolated values before they are combined. This brings native flexible string processing to the Python language and enables safety checks, web templating, domain-specific languages, and more.” Michael #4: juv A toolkit for reproducible Jupyter notebooks, powered by uv . Create, manage, and run Jupyter notebooks with their dependencies Pin dependencies with PEP 723 - inline script metadata Launch ephemeral sessions for multiple front ends (e.g., JupyterLab, Notebook, NbClassic) Powered by uv for fast dependency management Use uvx to run jupyterlab with ephemeral virtual environments and tracked dependencies. Extras Brian: Status of Python versions new-ish format Use this all the time. Can’t remember if we’ve covered the new format yet.

Topics covered in this episode: Git Town solves the problem that using the Git CLI correctly PEP 751 – A file format to record Python dependencies for installation reproducibility git-who and watchgha Share Python Scripts Like a Pro: uv and PEP 723 for Easy Deployment Extras Joke Watch on YouTube About the show Sponsored by Posit Package Manager : pythonbytes.fm/ppm Connect with the hosts Michael: @mkennedy@fosstodon.org / @mkennedy.codes (bsky) Brian: @brianokken@fosstodon.org / @brianokken.bsky.social Show: @pythonbytes@fosstodon.org / @pythonbytes.fm (bsky) Join us on YouTube at pythonbytes.fm/live to be part of the audience. Usually Monday at 10am PT. Older video versions available there too. Finally, if you want an artisanal, hand-crafted digest of every week of the show notes in email form? Add your name and email to our friends of the show list , we'll never share it. Michael #1: Git Town solves the problem that using the Git CLI correctly Git Town is a reusable implementation of Git workflows for common usage scenarios like contributing to a centralized code repository on platforms like GitHub, GitLab, or Gitea. Think of Git Town as your Bash scripts for Git, but fully engineered with rock-solid support for many use cases, edge cases, and error conditions. Keep using Git the way you do now, but with extra commands to create various branch types, keep them in sync, compress, review, and ship them efficiently. Basic workflow Commands to create, work on, and ship features. git town hack - create a new feature branch git town sync - update the current branch with all ongoing changes git town switch - switch between branches visually git town propose - propose to ship a branch git town ship - deliver a completed feature branch Additional workflow commands Commands to deal with edge cases. git town delete - delete a feature branch git town rename - rename a branch git town repo - view the Git repository in the browser Brian #2: PEP 751 – A file format to record Python dependencies for installation reproducibility Accepted From Brett Cannon “PEP 751 has been accepted! This means Python now has a lock file standard that can act as an export target for tools that can create some sort of lock file. And for some tools the format can act as their primary lock file format as well instead of some proprietary format.” File name: pylock.toml or at least something that starts with pylock and ends with .toml It’s exciting to see the start of a standardized lock file Michael #3: git-who and watchgha git-who is a command-line tool for answering that eternal question: Who wrote this code?! Unlike git blame, which can tell you who wrote a line of code, git-who tells you the people responsible for entire components or subsystems in a codebase. You can think of git-who sort of like git blame but for file trees rather than individual files. And watchgha - Live display of current GitHub action runs by Ned Batchelder Brian #4: Share Python Scripts Like a Pro: uv and PEP 723 for Easy Deployment Dave Johnson Nice full tutorial discussing single file Python scripts using uv with external dependencies Starting with a script with dependencies. Using uv add --script [HTML_REMOVED] [HTML_REMOVED] to add a /// script block to the top Using uv run Adding #!/usr/bin/env -S uv run --script shebang Even some Windows advice Extras Brian: April 1 pranks done well BREAKING: Guido van Rossum Returns as Python’s BDFL including Brett Cannon noted as “Famous Python Quotationist” Guido taking credit for “I came for the language but I stayed for the community” which was from Brett then Brett’s title of “Famous Python Quotationist” is crossed out. Barry Warsaw asking Guido about releasing Python 2.8 Barry is the FLUFL, “Friendly Language Uncle For Life “ Mariatta can’t get Guido to respond in chat until she addresses him as “my lord”. “… becoming one with whitespace.” “Indentation is Enlightenment” Upcoming new keyword: maybe Like “if” but more Pythonic as in Maybe: print("Python The Documentary - Coming This Summer!") I’m really hoping there is a documentary April 1 pranks done poorly Note: pytest-repeat works fine with Python 3.14, and never had any problems If you have to explain the joke, maybe it’s not funny. The explanation pi, an irrational number, as in it cannot be expressed by a ratio of two integers, starts with 3.14159 and then keeps going, and never repeats. Python 3.14 is in alpha and people could be testing with it for packages Test & Code is doing a series on pytest plugins pytest-repeat is a pytest plugin, and it happened to not have any tests for 3.14 yet. Now the “joke”. I pretended that I had tried pytest-repeat with Python 3.14 and it didn’t work. Test & Code: Python 3.14 won't repeat with pytest-repeat Thus, Python 3.14 won’t repeat. Also I mentioned that there was no “rational” explanation. And pi is an irrational number. Michael: pysqlscribe v0.5.0 has the “parse create scripts” feature I suggested! Markdown follow up Prettier to format Markdown via Hugo Been using mdformat on some upcoming projects including the almost done Talk Python in Production book . Command I like is mdformat --number --wrap no ./ uv tool install --with is indeed the pipx inject equivalent, but requires multiple --with's: pipx inject mdformat mdformat-gfm mdformat-frontmatter mdformat-footnote mdformat-gfm-alerts uv tool install mdformat --with mdformat-gfm --with mdformat-frontmatter --with mdformat-footnote --with mdformat-gfm-alerts uv follow up From James Falcon As a fellow uv enthusiast, I was still holding out for a use case that uv hasn't solved. However, after last week's episode, you guys finally convinced me to switch over fully, so I figured I'd explain the use case and how I'm working around uv's limitations. I maintain a python library supported across multiple python versions and occasionally need to deal with bugs specific to a python version. Because of that, I have multiple virtualenvs for one project. E.g., mylib38 (for python 3.8), mylib313 (for python 3.13), etc. I don't want a bunch of .venv directories littering my project dir. For this, pyenv was fantastic. You could create the venv with pyenv virtualenv 3.13.2 mylib313 , then either activate the venv with pyenv activate mylib313 and create a .python-version file containing mylib313 so I never had to manually activate the env I want to use by default on that project. uv doesn't have a great solution for this use case, but I switched to a workflow that works well enough for me: Define my own central location for venvs. For me that's ~/v Create venvs with something like uv venv --python 3.13 ~/v/mylib313 Add a simple function to my bashrc: ` workon() { source ~/v/$1/bin/activate } \ so now I can run \workon mylib313 or workon mylib38 when I need to work in a specific environment. uv's .python-version` support works much differently than pyenv's, and that lack of support is my biggest frustration with this approach, but I am willing to live without it. Do you Firefox but not Zen? You can now make pure Firefox more like Zen’s / Arc’s layout. Joke: So here it will stay See the follow up thread too! Also: Guido as Lord Python via Nick Muoh…

Add your name and email to our friends of the show list , we'll never share it. Michael #1: Why aren't you using uv ? Fun conversation on X by Armin Ronacher . Interesting quotes from the thread I get it replaces pip/pyenv, but should I also use it instead of the built in 'python -m venv .venv'? But I need python installed to make python programs? Because it places the venv in the project folder and I can't run executables from there due to corporate policy. Many such cases. No idea why astral doesn't address this with more urgency. Sounds like a bad corporate policy :) i’m too lazy to switch from pyenv and pip trust issues, what if they do a bait and switch … Because everyone said that about poetry and I'm not sure I'm really ready to get hurt again. Masochism Many times I tried a lot of similar tools and always come back to pip and pip-tools. Them are just work, why should I spend my time for something "cool" that will bring more problems? I tried this week but I was expecting a "uv install requests" instead of "uv add". Switched back to pipenv. we partially use it. will transition when Dependabot support is available. I’ll leave it with → Jared Scheel: Seeing a whole lotta Stockholm Syndrome in the replies to this question. Brian #2: Python Developer Tooling Handbook Tim Hopper “This is not a book about programming Python. Instead, the goal of this book is to help you understand the ecosystem of tools used to make Python development easier and more productive” Covers tools related to packaging, linting, formatting, and managing dependencies. Michael #3: Calling all doc writers: blacken-docs Run black on python code blocks in documentation files You can also install blacken-docs as a pre-commit hook. It supports Markdown, reStructuredText, and LaTex files. Additionally, you can run it on Python files to reformat Markdown and reStructuredText within docstrings. Brian #4: Reinventing notebooks as reusable Python programs marimo allows you to store notebooks as plaintext Python files properties Git-friendly: small code change => small diff easy for both humans and computers to read importable as a Python module, without executing notebook cells executable as a Python script editable with a text editor Also, … testing with pytest “Because marimo notebooks are just Python files, they are interoperable with other tools for Python — including pytest. “ “ Testing cells. Any cell named as test_* is automatically discoverable and testable by pytest. The same goes for any cell that contains only test_ functions and Test classes.” “Importantly, because cells are wrapped in functions, running pytest test_notebook.py doesn’t execute the entire notebook — just its tests.” Extras Brian: PyConUS announces Refund Policy for International Attendees New format now live for The Complete pytest Course Bundle and component courses Each course now available separately also pytest Primary Power is 13 lessons, 3.9 hours Using pytest with Projects , 10 lessons, 3.4 hours pytest Booster Rockets , 6 lessons, 1.3 hours of content New format is easier to navigate Better for people who like different speeds.

It's not an officially accepted HTTP status code, it was proposed in a 'joke' RFC. I guess Python - even though its name comes from the funny TV series Monty Python - is not so funny. httpx, your (or at least -my-) favorite HTTP module for python, does have the I_AM_A_TEAPOT constant. By the way, there are some HTTP status codes that changed their names in RFC 9110, for instance, http.HTTPStatus.UNPROCESSABLE_CONTENT (422, previously UNPROCESSABLE_ENTITY) Pride follow up fosstodon.org/@kytta/114034442981727301 Time to upgrade your mini ?

Add your name and email to our friends of the show list , we'll never share it. Brian #1: PEP 772 – Packaging governance process draft, created 21-Jan, by Barry Warsaw, Deb Nicholson, Pradyun Gedam “As Python packaging has matured, several interrelated problems with the current way of managing the technical development, decision making and processes have become apparent.” “This PEP proposes a Python Packaging Council with broad authority over packaging standards, tools, and implementations. Like the Python Steering Council, the Packaging Council seeks to exercise this authority as rarely as possible; instead, they use this power to establish standard processes.” PEP discusses PyPA, Packaging-WG, Interoperability Standards, Python Steering Council, and Expectations of an elected Packaging Council A specification with Composition: 5 people Mandate, Responsibilities, Delegations, Process, Terms, etc. Michael #2: Official Django MongoDB Backend Now Available in Public Preview Over the last few years, Django developers have increasingly used MongoDB, presenting an opportunity for an official MongoDB-built Python package to make integrating both technologies as painless as possible. Features The ability to use Django models with confidence . Developers can use Django models to represent MongoDB documents, with support for Django forms, validations, and authentication. Django admin support . The package allows users to fire up the Django admin page as they normally would, with full support for migrations and database schema history. Native connecting from settings.py . Just as with any other database provider, developers can customize the database engine in settings.py to get MongoDB up and running. MongoDB-specific querying optimizations . Field lookups have been replaced with aggregation calls (aggregation stages and aggregate operators), JOIN operations are represented through $lookup, and it’s possible to build indexes right from Python. Limited advanced functionality . While still in development, the package already has support for time series, projections, and XOR operations. Aggregation pipeline support . Raw querying allows aggregation pipeline operators. Since aggregation is a superset of what traditional MongoDB Query API methods provide, it gives developers more functionality. Brian #3: Developer Philosophy by qntm Intended as “advice for junior developers about personal dev philosophy”, I think these are just great tips to keep in mind. The items Avoid, at all costs, arriving at a scenario where the ground-up rewrite starts to look attractive This is less about “don’t do rewrites”, but about noticing the warning signs ahead of time. Aim to be 90% done in 50% of the available time Great quote: “The first 90% of the job takes 90% of the time. The last 10% of the job takes the other 90% of the time.” Automate good practices Think about pathological data “Nobody cares about the golden path. Edge cases are our entire job .” Brian’s note: But also think about the happy path. Documenting and testing what you think of as the happy path is a testing start and helps others understand your idea of how things are supposed to work. There’s usually a simpler way to write it Write code to be testable It is insufficient for code to be provably correct; it should be obviously, visibly, trivially correct Brian’s note: Even if it’s obviously, visibly, trivially correct, it will still break. So test it anyway. Michael #4: Python 3.13.2 released Python 3.13’s second maintenance release. About 250 changes went into this update Also Python 3.12.9, Python 3.12’s ninth maintenance release already. Just 180 changes for 3.12, but it’s still worth upgrading. For us, it’s simply rebuilding our Docker base (i.e. —no-cache) with these lines: RUN curl -LsSf https://astral.sh/uv/install.sh | sh RUN --mount=type=cache,target=/root/.cache uv venv --python 3.13 /venv Extras Brian: Still thinking about pytest plugins a lot. The top pytest plugin list Has been updated for Feb Is starting to include things without “pytest” in the name, like Hypothesis and Syrupy. Eventually I’ll have to add “looking at trove classifiers” as part of the search, but for now, let me know if you’re favorite is missing. Includes T&C podcast episode links if I’ve covered it on the show. There’s 2 so far Michael: There's a new release of PyScript out. All the details are here: Highlight is new PyGame-CE support.

Topics covered in this episode: content-types package for better MIME types/Content-Type Wagtail 6.4 Build It Yourself Build backend popularity over time Extras Joke Watch on YouTube About the show Sponsored by us! Support our work through: Our courses at Talk Python Training The Complete pytest Course Patreon Supporters Connect with the hosts Michael: @mkennedy@fosstodon.org / @mkennedy.codes (bsky) Brian: @brianokken@fosstodon.org / @brianokken.bsky.social Show: @pythonbytes@fosstodon.org / @pythonbytes.fm (bsky) Join us on YouTube at pythonbytes.fm/live to be part of the audience.

Add your name and email to our friends of the show list , we'll never share it. Michael #1: content-types package for better MIME types/Content-Type It started with this comment from Raf . mimetypes — Map filenames to MIME types It is oddly missing very common types and varies by platform, OS install and other factors ( see this function ). Search around and found python-magic . Seems great but ImportError: failed to find libmagic. Check your installation → brew install libmagic magic.from_file("testdata/test.pdf") → FileNotFoundError: [Errno 2] No such file or directory: 'testdata/test.pdf' hmm So I had to create my own. Introducing content-types A Python library to map file extensions to MIME types. Unlike other libraries, this one does not try to access the file or parse the bytes of the file or stream. It just looks at the extension. Better support than mimetypes builtin. Brian #2: Wagtail 6.4 Release notes Lots of great updates, but I want to zoom in on background tasks. 6.4 includes django-tasks which is an available implementation of DEP 0014: Background workers This proposal is accepted and this thread includes a great talk from DjangoCon Europe 2024 Why is this cool? Even though django-tasks says it’s “under active development”, as long as you pin the version and test your behavior depending on this, it must be ready to use if wagtail is going for it. Don't you think? Michael #3: Build It Yourself from Armin Ronacher, sent in by Rafael Weingartner An excellent article pushing back on too many dependencies Maybe the advice of always prefer code reuse isn’t that great after all? It’s much much easier to solve small little problems these days due to AI. Take Postmark as an example. “It's time to have a new perspective: we should give kudos to engineers who write a small function themselves instead of hooking in a transitive web of crates. We should be suspicious of big crate graphs. Celebrated are the minimal dependencies, the humble function that just quietly does the job, the code that doesn't need to be touched for years because it was done right once.” - Armin Brian #4: Build backend popularity over time Bastian Venthur This is just for projects using pyproject.toml Apparently he did this last year as well , so we can see some trends. Results setuptools: ~50% (last year ~50%) poetry: ~30% (last year ~33%) hatchling: (percent not listed, but looks like 12-15%), (last year 10%) flit: ~5% (last year ~10%) other: (above flit now) Analysis: setuptools continues to grow in absolute numbers and maintain it’s percentage. poetry declining hatchling growing flit declining Brian commentary This is not surprising to me. I generally use hatchling for more control, and setuptools for simple projects. I think we might end up with mostly setuptools and hatchling in a couple years.

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. Test & Code episode with Michael, ep 145, “For those about to mock” 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 #4: mimetype.io I’m always forgetting content types!
