Switching Pip to Uv in a Dockerized Flask / Django App

I am totally against Python tooling being written in a language other than Python. I get that C extensions exist and for the most part Python is synonymous with CPython.

I think 2 languages are enough, we don't need a 3rd one that nobody asked for.

I have nothing against Rust. If you want a new tool, go for it. If you want a re-write of an existing tool, go for it. I'm against it creeping into an existing eco-system for no reason.

A popular Python package called Pendulum went over 7 months without support for 3.13. I have to imagine this is because nobody in the Python community knew enough Rust to fix it. Had the native portion of Pendulum been written in C I would have fixed it myself.

In my ideal world if someone wanted fast datetimes written in Rust (or any other language other than C) they'd write a proper library suitable for any language to consume over FFI.

So far this Rust stuff has left a bad taste in my mouth and I don't blame the Linux community for being resistant.

What, exactly, is your objection to using rust (or any non-python/C language) for python tooling? You didn't actually give any reasons

I believe he alluded to it here...

"I have to imagine this is because nobody in the Python community knew enough Rust to fix it. Had the native portion of Pendulum been written in C I would have fixed it myself."

Correct. There better be a damn good reason to add another language to the ecosystem other than it's that particular developer's new favorite language.

Is there anything being done in uv that couldn't be done in Python?

How many people are digging into and contributing to any python tooling? How is C meaningfully more accessible than rust? Plenty of people (yet also a significant minority overall) write each of them.

Speed, at the very least.

You could just ignore uv and use whatever you want...

> How is C meaningfully more accessible than rust

They've been teaching C in universities for like 40 years to every Computer Science and Engineering student. The number of professionally trained developers who know C compared to Rust is not even close. (And a lot of us are writing Python because it's easy and productive, not because we don't know other languages.)
