Conda
conda-env does not exist after entering the conda-shell without first calling conda-install, so I think the wiki is missleading here, or the package has a bug. conda-shell, conda-install have no effect and nothing happens. Bash just says it can't find that command.
shellHook explanation
It's not clear what the meaning of all the `shellHook` stuff is for, esp. the unset SOURCE_DATE_EPOCH
bit.
How to use specific Python version?
I'm working on a project where we're using a specific patch version of Python. How would I set this up? This uses a Python fork, but I'm looking for a specific version of the official Python package.

Flake example for use with nix develop
I was trying to get python with packages as defined by a flake, and found https://dev.to/deciduously/workspace-management-with-nix-flakes-jupyter-notebook-example-2kke a useful discussion. I propose to add an example:
{
description = "Python environment";
inputs.nixpkgs.url = "nixpkgs/nixos-22.11";
outputs = {nixpkgs, ...}: let
system = "x86_64-linux";
pkgs = import nixpkgs {inherit system;};
in {
devShells.${system}.default = pkgs.mkShell {
buildInputs = [
(pkgs.python3.withPackages (p: [
p.requests
]))
];
shellHook = "python";
};
};
}
Full
Can we add a section about Full (e.g. python312Full) and non-Full (e.g. python312) versions? Whats the difference and in which situation use on or the other?
