Two years of work mapping out the Python tooling ecosystem just turned into a physical object

@carehart Thank you for reporting, fixed

[Charlie Marsh @charliermarsh]

uv is one year old today. Hard to believe its only been a year. The growth, adoption, and impact surpassed my wildest expectations.

Happy birthday, uv! 🥳

[Charlie Marsh @charliermarsh]

We’re building a new static type checker for Python, from scratch, in Rust.

From a technical perspective, it’s probably our most ambitious project yet. We’re about 800 PRs deep!

Really interesting #python chat here between @cjolowicz and @bbelderbos on the @pybites podcast. Claudio's excellent @OReillyMedia book #Hypermodern #Python #Tooling can be bought here: https://t.co/uTx8Llangx

Chatting with Bob Belderbos on the @pybites podcast about my recent book Hypermodern Python Tooling and why coding is like playing music 🎶 Thanks Bob, really enjoyed this!

Great talking with you Claudio, thanks for sharing + the great work you're putting out, really helpful for us #Python developers. 🐍 😍

uv has shipped `uv sync —no-editable` in 0.4.11 which means we can use it in multi-stage builds! 🎉 (instead of a combo of `uv sync` + `uv pip install`)

[Hynek Schlawack @hynek]

Since whenever I talk about #Python & #Docker, I invariably get told that virtual environments inside of Docker make no sense, I’ve spent my weekend writing down why I think it does. [1/2]

[Charlie Marsh @charliermarsh]

Today, we're shipping a series of features that move uv beyond a pip alternative, and into an end-to-end solution for managing Python projects, command-line tools, single-file scripts, and even Python itself.

A single, unified tool. Like Cargo, for Python.

It's very fast.

[Henry Schreiner III @HenrySchreiner3]

Enjoying the changelog from yesterday's pip 24.2 release - almost every entry is talking about improving performance! I'm sure @charliermarsh's uv has something to do with that! https://t.co/o0QlOWt5fI

Announcing the Astral OSS Fund.

We're giving > $3,000 per Astral team member per year to open source projects, maintainers, and foundations, inspired by @getsentry's OSS Pledge.

[Claudio Jolowicz @cjolowicz]

@agpt8 Yes I’m planning to update the Hypermodern Python Cookiecutter to reflect what’s in the book.

[Claudio Jolowicz @cjolowicz]

@alexandre_ganso Thank you for caring! You can’t buy the book directly from me, but you can support your local bookstore 😉

[Claudio Jolowicz @cjolowicz]

@sudotimar If you just want to create a venv, use uv. For higher-level tools, the book should help you make the right tradeoff for your project and team. Also, venvs are a building block for distinct workflows (think Poetry vs Nox vs pipx) that aren’t mutually exclusive.

[Claudio Jolowicz @cjolowicz]

@sudotimar Yes. There are many tools out there that help managing venvs, from bare bones to high level. The book covers several. Chapter 2 also gives you a mental model of what a venv is and why you should use it.

[Claudio Jolowicz @cjolowicz]

@R_E_Beer @bbelderbos @pybites Sounds great!

In my quest to produce a shorter video, I’ve produced my longest so far:

tox vs Nox: What are they for & How do you choose?: https://t.co/J3OYSB7udi

In which I introduce those two indispensable tools and reflect my own usage of BOTH. Enjoy!

[Hynek Schlawack @hynek]

I’ve spent some time playing with uv and GitHub Actions and action/cache.

The latter’s behavior is a bit idiosyncratic, but I think I’ve built something overall usable: https://t.co/OgYsutQnkt

LMK what y’all think.
