How to change your default python version.

1. Make sure python 3 is installed and up to date:

sudo apt-get update && sudo apt-get upgrade -y

2. Set up the alternative versions (Debian or Ubuntu):

sudo update-alternatives --install /usr/bin/python python /user/bin/python2.7 1

sudo update-alternatives --install /usr/bin/python python /user/bin/python3.7 2

3. To change versions use:

sudo update-alternatives --config python

If you want a simple command to swap versions use this little bash script!

Place it on your path for easy execution!
