It’s not really recommended to change the distribution’s default version of Python because it might break system scripts. Typically you just add “#!/usr/bin/env python3” at the top of all those scripts that actually need Python 3.

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