You should see a list of python versions like this: Sudo update-alternatives -install /usr/bin/python3 python3 /usr/bin/python3.9 2 Sudo update-alternatives -install /usr/bin/python3 python3 /usr/bin/python3.8 1 (for example use “/usr/bin/python3.10” if you got 3.10 from step 1).

You can simply copy and paste these commands. Familiarity with the command line will be helpful, but otherwise no assumptions are made about your technical skill. (other versions of Ubuntu are probably fine, but 20.04 was used for testing this guide)

A computer, virtual machine (AWS, Google Cloud, etc.), or windows subsystem for linux (WSL) running ubuntu version 20.04.

The methods outlined here are intended for a fresh installation of Ubuntu 20.04 LTS. This is a step-by-step guide for installing Python3.9 and the python virtual environment manager: venv.
