Garter Stitch Based Lace Pattern
This script contains a class that shows how to implement the singleton pattern in Python. A singleton is a class that makes sure only one instance of it is ever created. Typically such classes are used to manage resources that by their very nature can only exist once.

In the factory pattern script you have an object that creates other objects.Factory is useful to separate implementation from interface. It adds a new indirection layer. When you want to instanciate an object you call its factory and the factory creates the instance.

This is a Python implementation of the observer pattern. It defines a one-to many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically.
