Advanced Python Programming

Summary

In this chapter, we discussed the bridge pattern. Sharing similarities with the adapter pattern, the bridge pattern is different from it, in the sense that it is used up-front to define an abstraction and its implementation in a decoupled way so that both can vary independently.

The bridge pattern is useful when writing software for problem domains such as operation systems and device drivers, GUIs, and website builders where we have multiple themes and we need to change the theme of a website based on certain properties.

To help you understand this pattern, we discussed an example in the domain of content extraction and management, where we defined an interface for the abstraction, an interface for the implementor, and two implementations. ...
