RPSLS Game.py

"""
	This is a Python script that is used to create the RPSLS i.e. 
    Rock-Paper-Scissors-Lizard-Spock game. 
    
    This is my first project.
    
    In this game, the user plays against the computer and provides an
    input from the options available to them. The exact rules are a follows: - 

    The method for determining the winner is to assign each of the five choices a number:

	0 — rock
	1 — Spock
	2 — paper
	3 — lizard
	4 — scissors
	
	In this expanded list, each choice wins against the preceding two choices and loses against the following two choices 
	(if rock and scissors are thought of as being adjacent using modular arithmetic).
