The DRY Principle with Decorators
Explore how Python decorators promote the DRY principle by allowing you to reuse code across functions and classes. Understand when to create decorators based on reusable patterns, and learn best practices to keep your design simple while enhancing code maintainability through abstraction and separation of concerns.
We'll cover the following...
We have seen how decorators allow us to abstract away certain logic into a separate component. The main advantage of this is that we can then apply the decorator multiple times to different objects in order to reuse code. This follows the DRY principle since we define certain knowledge once and only once.
The retry mechanism
The retry mechanism is a good example of a decorator that can be applied multiple times to reuse code. Instead of making each particular function include its own ...
