Python utility methods for opening files (Mac only)

gistfile1.txt

#!/usr/bin/env python3
""" Some Mac-specific utility methods I have found useful for opening files. Uses mdfind, a built-in command-line 
    interface to spotlight's desktop cache, so results are usually instantaneous.
    
    Demo:
