Create python venv with specific python version

To specify the specific python version to use, you can specify it as follows in the .envrc file

layout python /usr/bin/python3.11

I also needed to install the python-venv package for python 3.11


❯ sudo apt install python3.11-venv
let () = print_endline "THIS" in
let () = print_endline "IS" in
print_endline "3110";;
(* Can also be written as *)
print_endline "THIS";
print_endline "IS";
print_endline "3110"
(* Source: https://courses.cs.cornell.edu/cs3110/2021sp/textbook/basics/printing.html *)

Using direnv + opam via the following .envrc

export OPAMSWITCH="$HOME/path/to/opam/switch"
eval $(opam env)
