You could try adding a permanent alias:

  1. Open your .bashrc file: vim ~/.bashrc

  2. Add this to the end of the file:

alias sudo="sudo " (credit to https://askubuntu.com/a/22043)

alias python="INSERT-PATH-TO-PYTHON-EXE-HERE"

alias python3="INSERT-PATH-TO-PYTHON-EXE-HERE"

alias python3.9="INSERT-PATH-TO-PYTHON-EXE-HERE"

  1. If you have any of the following: .bash_aliases, .bash_login, .profile. Add to it instead
  2. Reload .bashrc: source ~/.bashrc

Check python version on terminal - python --version

Get root user privileges. On terminal type - sudo su

Write down the root user password.

Execute this command to switch to python 3.6.

update-alternatives --install /usr/bin/python python /usr/bin/python3 1

Check python version - python --version
