The author’s point about “not caring about pip vs poetry vs uv” is missing that uv directly supports this use case, including PyPI dependencies, and all you need is uv and your preferred Python version installed: https://docs.astral.sh/uv/guides/scripts/#using-a-shebang-to...
I thought that too, but I think the tricky bit is if you're a non-python user, this isn't yet obvious.
If you've never used Clojure and start a Clojure project, you will almost definitely find advice telling you to use Leiningen.
For Python, if you search online you might find someone saying to use uv, but also potentially venv, poetry or hatch. I definitely think uv is taking over, but its not yet ubiquitous.
Ironically, I actually had a similar thing installing Go the other day. I'd never used Go before, and installed it using apt only to find that version was too old and I'd done it wrong.
Although in that case, it was a much quicker resolution than I think anyone fighting with virtual environments would have.
That's my experience. I'm not a Python developer, and installing Python programs has been a mess for decades, so I'd rather stay away from the language than try another new tool.
Over the years, I've used setup.py, pip, pipenv (which kept crashing though it was an official recommendation), manual venv+pip (or virtualenv? I vaguely remember there were 2 similar tools and none was part of a minimal Python install). Does uv work in all of these cases? The uv doc pointed out by the GP is vague about legacy projects, though I've just skimmed through the long page.
IIRC, Python tools didn't share their data across projects, so they could build the same heavy dependencies multiple times. I've also seen projects with incomplete dependencies (installed through Conda, IIRC) which were a major pain to get working. For many years, the only simple and sane way to run some Python code was in a Docker image, which has its own drawbacks.

One of the neatest features of uv is that it uses clever symlinking tricks so if you have a dozen different Python environments all with the same dependency there's only one copy of that dependency on disk.
However... scripting requires (in my experience), a different ergonomic to shippable software. I can't quite put my finger on it, but bash feels very scriptable, go feels very shippable, python is somewhere in the middle, ruby is closer to bash, rust is up near go on the shippable end.
Good scripting is a mixture of OS-level constructs available to me in the syntax I'm in (bash obviously is just using OS commands with syntactic sugar to create conditional, loops and variables), and the kinds of problems where I don't feel I need a whole lot of tooling: LSPs, test coverage, whatever. It's languages that encourage quick, dirty, throwaway code that allows me to get that one-off job done the guy in sales needs on a Thursday so we can close the month out.
Go doesn't feel like that. If I'm building something in Go I want to bring tests along for the ride, I want to build a proper build pipeline somewhere, I want a release process.
I don't think I've thought about language ergonomics in this sense quite like this before, I'm curious what others think.
Talking about Python "somewhere in the middle" - I had a demo of a simple webview gtk app I wanted to run on vanilla Debian setup last night.. so I did the canonical-thing-of-the-month and used uv to instantiate a venv and pull the dependencies. Then attempted to run the code.. mayhem. Errors indicating that the right things were in place but that the code still couldn't run (?) and finally Python Core Dumped.. OK. This is (in some shape or form) what happens every single time I give Python a fresh go for an idea. Eventually Golang is more verbose (and I don't particularly like the mod.go system either) but once things compile.. they run. They don't attempt running or require xyz OS specific hack.
I've had similar issues with anaconda, once upon a time. I've hit a critical roadblock that ruined my day with every single Python dependency/environment tool except basic venv + requirements.txt, I think. That gets in the way the least but it's also not very helpful, you're stuck with requirements.txt which tends to be error-prone to manage.
I don’t really understand the initial impetus. I like scripting in Python. That’s one of the things it’s good at. You can extremely quickly write up a simple script to perform some task, not worrying about types, memory, yada yada yada. I don’t like using Python as the main language for a large application.
It seems to be Linux specific (does it even work on other unix like OSes?) and Linux usually has a system Python which is reasonably stable for things you need scripting for, whereas this requires go to be installed.
You could also use shell scripting or Python or another scripting language. While Python is not great at backward compatibility most scripts will have very few issues. Shell scripts are backward compatible as are many other scripting languages are very backward compatible (e.g. TCL) and they areG more likely to be preinstalled. If you are installing Go you could just install uv and use Python.
The article does say "I started this post out mostly trolling" which is part of it, but mostly the motivation would be that you have a strong preference for Go.
You don't even need to end the file in `.go` or the like when using shebangs, and any self-respecting editor will be good at parsing out shebangs to identify file types (... well, Emacs seems to do it well enough for me)
no need to name your program foo.go when you could just name it foo
I love it. I'm using Go to handle building full stack javascript apps, which actually works great since esbuild can be used directly inside a Go program. The issue is that it's a dependency, so I settled for having a go mod file and running it directly with Go. If somehow these dependencies could be resolved without an explicit module configured (say, it was inline in the go file itself) it would be perfect. Alas, it will probably never happen.
That being said...use Go for scripting. It's fantastic. If you don't need any third party libraries this approach seems really clean.
I make computers do things, but I never act like my stuff is the only stuff that makes things happen. There is a huge software stack of which my work is just the final pieces.
The problem with calling it “full stack” (even if it has a widely understood meaning) is that it implicitly puts the people doing the actual lower-level work on a pedestal. It creates the impression that if this is already “full stack,” then things like device drivers, operating systems, or foundational libraries must be some kind of arcane magic reserved only for experts, which they aren’t.
The term “full stack” works fine within its usual context, but when viewed more broadly, it becomes misleading and, in my opinion, problematic.
Or, alternatively, it ignores and devalues the existence of these parts. In both cases, it's a weird "othering" of software below a certain line in the, ahem, full stack.
And it's okay. It doesn't mean it should be this way for everyone else.
It is pretty common (and been so for at least two decades) for web devs to differentiate like so: backend, frontend or both. This "both" part almost always is replaced by "full stack".
When people say this they just mean they do both parts of a web app and have no ill will or neglect towards systems programmers or engineers working on a power plant.
Tangent but... I kinda like the Python language. What I don't like about Python is the way environments are managed.
This is something I generally believe, but I think it's particularly important for things like languages and runtimes: the idea of installing things "on" the OS or the system needs to die.
Per-workspace or per-package environment the way Go, Rust, etc. does it is correct. Installing packages globally is wrong.
There should not be such a thing as "globally." Ideally the global OS should be immutable or nearly so, with the only exception being maybe hardware driver stuff.
(Yes I know there's stuff like conda, but that's yet another thing to fix a fundamentally broken paradigm.)
Tcc even supports that with `#!/usr/local/bin/tcc -run`, although I don't understand people who use c or go for "scripting", when python, ruby, TCL or perl have much superior ergonomics.
This was a relatively old project that used a C program as build system / meta generator. All you needed was a working C compiler (and your shell to execute the first line). From there, it built and ran a program that generated various tables and some source code, followed by compiling the actual program. The final program used a runtime reflection system, which was set up by the generated tables and code from the first stage.
The main reason was to do all this without any dependencies beyond a C compiler and some POSIX standard library.
Using `uv` with python is significantly safer and better. At least you get null safety. Sure, you can't run at the speed of light, but at least you can have some decent non-halfarsed-retrofitted type checking in your script.
If you've never used Clojure and start a Clojure project, you will almost definitely find advice telling you to use Leiningen.

Yes. The goal of uv is to defuck the python ecosystem and they're doing a very good job at it so far.
One of the neatest features of uv is that it uses clever symlinking tricks so if you have a dozen different Python environments all with the same dependency there's only one copy of that dependency on disk.

No, bash is technically not "more" OS than e.g. Python. It just happens that bash is (often) the default shell in the terminal emulator.

Device drivers, task switching, filesystem, memory management and all?

But it is already established in the industry, and fighting it is unlikely to yield any positive outcomes.

I feel like this is the unofficial Go motto, and it almost always ends up being a terrible idea.
