        """Basic Python Cheat Sheet by Filip Kral on 2015/02/16"""
        
        """
        Python is a cross-platform, interpreted, object-oriented programming language.
        That means you can run it on Linux, Windows, Mac, and other platforms,
        you don't need to compile your code to execute it because it is compiled on
        the fly, and you can use classes and objects.
        This cheat sheet summarizes the very basics of Python programming syntax.
        It is by no means exhaustive! For more comprehensive yet still compact reference

Initialisation

Git needs to know what content does it needs to track (which directory), therefore we initialise them as a git repository by the command:

cd hello-world/
git init

It will output something like:

Initialized empty Git repository in /Users/rahuljha/Documents/hello-world/.git/
