Ubuntu

Python2

$ sudo apt install python2

Check the Python version.

$ python2 -V
Python 2.7.17

Setting Up Python 3

Ubuntu 20.04 and other versions of Debian Linux ship with Python 3 pre-installed. To make sure that our versions are up-to-date, let’s update and upgrade the system with the apt command to work with Ubuntu’s Advanced Packaging Tool:

$ sudo apt update; sudo apt -y upgrade

The -y flag will confirm that we are agreeing for all items to be installed, but depending on your version of Linux, you may need to confirm additional prompts as your system updates and upgrades.

Once the process is complete, we can check the version of Python 3 that is installed in the system by typing:

python3 -V

Upgrade Python

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install python3.11

Copy
echo "alias py=/usr/bin/python3" >> ~/.bashrc
echo "alias python=/usr/bin/python3" >> ~/.bashrc
