Analysis of Good Decorators
Explore the characteristics of effective Python decorators by analyzing real-world examples from projects like Celery and web frameworks. Understand how good decorators promote encapsulation, separation of concerns, reusability, and provide clean interfaces to improve your code quality and maintainability.
As a closing note, let's analyze good decorators to get an idea of how they're used in practice. Let's review some examples of good decorators and how they are used both in Python itself and in popular libraries. The idea is to get guidelines on how good decorators are created.
Traits of good decorators
Before jumping into examples, let's first identify traits that good decorators should have:
Encapsulation, or separation of concerns: A good decorator should effectively separate different responsibilities between what it does and what it is decorating. It cannot be a leaky ...
