Using Pyenv to Manage Python Environments

sudo apt install pyenv

pyenv init

Sample output, run locally and append lines as described to your shell .rc file

exec "$SHELL"

Reload your shell .rc file

pyenv install 3.11.11

Install python3.11 binaries

mkdir ./python_project

cd ./python_project

pyenv local 3.11.11

Creates a .python-version file in the current directory, so that when the python command is invoked, it will always run with version 3.11.11 inside ./python_project. Navigating outside of this directory reverts to the global Python version in the default environment.
