Python Design Patterns: Working with Behavioral Design Patterns

Explore the design and implementation of five commonly used behavioral design patterns: Strategy Chain of Responsibility Observer Command and Iterator. Examine how these patterns can be used in Python built-in functions in simple and complex use cases for performing undo operations and with Python special methods. Key concepts covered in this course include the Strategy pattern how to design and implement the  pattern and how it is used in Python built-in functions; and learning the Chain of Responsibility pattern and how to write code to implement the pattern. Next you will learn about the Observer pattern and how to implement the pattern for a simple use case and how to implement the pattern for a more complex use case. Finally learners will study the Command pattern and how to implement the pattern to perform undo operations; and learn the Iterator pattern and its applications and learn to design an Iterator by using special methods in Python.
