Learning Python Application Development

Chapter 6. Design Patterns

This chapter will introduce you to some commonly used design patterns. Here is how the chapter is organized:

• We will start with a quick introduction to design patterns, followed by a discussion on some Python language features that help to simplify their implementation.
• Next, with the help of a fantasy game theme, we will discuss the following design patterns:
  • Strategy pattern
  • Simple and abstract factory pattern
  • Adapter pattern
• For each pattern, a simple game scenario will demonstrate a practical problem. We will see how the design pattern can help solve this problem.
• We will also implement each of these patterns using a Pythonic approach.

There are several known design patterns out there. As outlined earlier, we will discuss ...
