• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

I tried installing uv

[radiant rapids]

okay, what happens if you do uv --version in the shell?

[indigo quiver]

this what I currently got on powershell

[radiant rapids]

it's easier for people to read when you show text as text, not as a screenshot.

everything's installed!

To add C:\Users\batal\.local\bin to your PATH, either restart your shell or run:

    set Path=C:\Users\batal\.local\bin;%Path%   (cmd)
    $env:Path = "C:\Users\batal\.local\bin;$env:Path"   (powershell)

why is also in my user directory?
I ran it with admin though

[radiant rapids]

the last part has instructions that you should follow.

are you working on a python project or writing individual scripts or what?

[indigo quiver]

I wanna get started learning python again

and aim to learn to use VsCode

[radiant rapids]

there's a vs code extension for uv

[stable crest]

honestly there is no need for that

make venv with

python -m venv .venv

[radiant rapids]

they're asking how to use uv

[stable crest]

just saying no need for extension

[radiant rapids]

have you used uv before?

[stable crest]

yes pretty basic use

[radiant rapids]

uv often makes venvs on-the-fly, so if there's an IDE extension that supports it, that's the way to go.

[stable crest]

on-the-fly sounds fancy

[radiant rapids]

it's fancy as fuck

[stable crest]

so what it can do

[radiant rapids]

suppose you have a script that isn't part of a project. you can do

uv add --script my_script.py requests pandas tabulate

and it adds comments to my_script.py saying that those are the requirements for that script

and then you do uv run my_script.py, and it either makes a venv with those requirements on-the-fly, or uses the one from the last time you ran that script

and the venv isn't added to that directory. it lives in uv's cache

so it's a cleaner way of managing dependencies

[stable crest]

i have read about this thing it was in some pep for scripte requirements

[radiant rapids]

yes, it follows the protocol in that pep

[indigo quiver]

like I also use idle

[stable crest]

sounds like total overkill but i wont complain

[radiant rapids]

it's actually underkill

you don't need to make individual venvs for one-off scripts

[stable crest]

mainly i use global for that

but then again it is not for regular use

[radiant rapids]

what if other people have to use that script, and it requires a specific combination of dependencies? you don't want to have to do pip freeze and look for the lines that are relevant.

with uv, all you have to do is send them the one script, without any additional files, and uv parses the specific set of requirements from the comments and makes the venv.

[indigo quiver]

so I just install uv extension on vscode?

how about it being in my user directory? instead of system

[radiant rapids]

idk, I haven't used VSC. I only know about the uv extension from a help session I did a few days ago.

[indigo quiver]

curious, what ide u use?

[radiant rapids]

pycharm. you can use whichever one you want.
