Example 3: Gaming with pygame

To illustrate the power of Python, this example creates a fully-functional arcade game based
on the classic game of Snake or Nibbles . To accomplish this, it uses an external Python library
called pygame .
Originally written by Pete Shinners, pygame is a collection of python modules designed to
add new functionality to the language—functionality specifically designed to make it easy to
write a game in Python . Each pygame module provides a function required by a modern
game, including sound, graphics and even networking support . Although it's possible to
write a game in Python without using pygame, it's a lot easier if you take advantage of the
code already written in the pygame library .
