Python Symlink

Symlinks python to python3 when Python 2.7 is not installed

Overview

This script checks if python3 is available and if python is not available. If both are true, then the script symlinks python to python3 so that the python command uses python3.

This is useful if you do not want to install Python 2.7 and would like Python 3 to be used in all scenarios where Python is invoked with the python command.
