Composite Design Pattern

The script illustrates the composite design pattern by using hierarchical dictionaries. It can be used to process hierarchical, tree-based data structures using Python dictionaries.

This class implements the observer design pattern. Acting as a registration hub, it fires simple Events when requested.

This script is a sample implementation of the 'Null Object' design pattern. Roughly, the goal with Null objects is to provide an 'intelligent' replacement for the often used primitive data type None in Python or Null (or Null pointers) in other languages. These are used for many purposes...
