Python Design Patterns I

In the previous chapter, we were briefly introduced to design patterns, and covered the iterator pattern, a pattern so useful and common that it has been abstracted into the core of the programming language itself. In this chapter, we'll be reviewing other common patterns, and how they are implemented in Python. As with iteration, Python often provides an alternative syntax to make working with such problems simpler. We will cover both the traditional design, and the Python version for these patterns.

In summary, we'll see:

  • Numerous specific patterns
  • A canonical implementation of each pattern in Python
  • Python syntax to replace certain patterns
