Chapter 12: Applying GOF Design Patterns – Part 1
In this chapter, we will look at the concept of design patterns in Python 3 and its various categories, along with examples of how they can be applied while developing software using Python.
The concept of design patterns originated from the book Design Patterns Elements of Reusable Object-Oriented Software by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, Addison-Wesley, which was written in C++. This concept was later extended to other object-oriented programming (OOP) languages.
In this chapter, we are going to look at how these design patterns can be applied in Python using our core example of ABC Megamart.
We will cover the following main topics:
- An overview of design patterns
- Exploring behavioral design patterns
By the end of this chapter, you should understand some important behavioral design patterns and how they can be implemented in various applications.
