Advanced Python Programming - Second Edition

Chapter 16: The Factory Pattern

Design patterns are reusable programming solutions that have been used in various real-world contexts and have proved to produce the expected results. In this chapter, we will learn about one of the most common design patterns: the factory design pattern. As we will see later, this pattern makes it easier to track which objects are created within a program, thus separating the code that creates an object from the code that uses it. We will study the factory design pattern's two forms: the factory method and the abstract method.

In this chapter, we will cover the following topics:

• Understanding design patterns
• Implementing the factory method
• Applying the abstract factory

By the end of this chapter, we will have ...
