It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. Strategy is a behavioral design pattern that turns a set of behaviors into objects and makes them interchangeable inside original context object. Practice Programming/Coding problems (categorized into difficulty level - hard, medium, easy, basic, school) related to Design-Pattern topic. The code mentioned below is a simple demonstration of how to implement decorator design pattern in Python. Lets you construct complex objects step by step. Creational Patterns - These design patterns provide a way to create objects while hiding the creation logic, rather than instantiating objects directly using new opreator.
