How to install up-to-date python for a user only?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If you can install nix (you can install it per user) then you can have whatever you want in a temporary shell with nix-shell -p python
nix profile install nixpkgs#python if you want it actually installed
Home manager is also entirely user level I believe and lets you use a declarative config too
I tried to get install instructions for home-manager and they only had them if you are already on nix?
I didnt get it
I'd try installing just regular nix (package manager, not operating system) rather than home manager, that's what I do on by Debian pi
There's an install script on their website that does it all for you
Nice! Yes I will do that. What is the difference between the 2?
Careful, there's three different terms in the mix here:
NixOS: an entire operating system, you don't need this.
nix: the nix package manager. This is what you'll need to install. look for single user install in the instructions.
home-manager: a module for nix. It's aim is to allow declarative configuration of a users' home configuration (and allow easier per-user install of packages on a global nix install).
If you want to go down the nix route, which I would recommend if you enjoy tinkering and having fine control over your system, you should start with installing nix. With that, you can already setup a shell that has the newest version of python available.
Going beyond that, I can link you some more resources, if you want c:
So "nix install" means placing a nix binary somewhere in my user $PATH?
Home-manager > nix profile
Also, nix-shell is supposed to be used for debugging, and nix shell/run/develop for using packages without installing them
Source on the second statement? My understanding was that nix-shell is legacy for systems without flakes and nix-command enabled, and are being replaced by nix shell/run/develop
Does home manager work standalone without having nix first? I've never installed it on non-nixos
Nix shell is absolutely for running packages without installing them it literally tells you to do that in the terminal hint
Nix run iirc only works with flakes
