A small description on how to program using Python Programming Language on Mac OS's Terminal.
We don't need any third party Python Interpreter / compiler to do so.
Simply type "python" (without inverted commas) on your Mac Terminal Window and you can start using your Mac's inbuilt terminal as a Python Language interpreter.
More information on Python can be obtained here: http://www.python.org
