All these answers assume your system doesn't have Python 2 installed, otherwise you might cause other issues.

The recommended way if you are using BASH on Linux or UNIX, is to edit the .bashrc file in your home directory :

~/.bashrc

The '~' 'points to your home directory '/home/username'. Once you have this file open, add the following to the bottom :

alias python='python3'

Now typing 'python' will automatically run Python 3. I use this method because it doesn't require altering system files, but you can't run as sudo (which might be a good thing).

If you need to use 'sudo', create a symbolic link with the following command:

sudo ln -s /usr/bin/python3 /usr/local/bin/python

Alternatively install the 'python-is-python3' package, as mentioned by @chepner the following assumes you are using the apt package manager, and similarly does nothing more than create a symbolic link :

sudo apt install python-is-python3

1.Go to terminal type - python --version 2.Log in with root privileges sudo su 3.Execute this command update-alternatives --install /usr/bin/python python /usr/bin/python3 4. Check version again

You can install python-is-python3 package: $ sudo apt install python-is-python3
