In this chapter, we will explore decorators and see how they are useful in many situations where we want to improve our design. We will start by first exploring what decorators are, how they work, and how they are implemented.

- To learn how to implement decorators that apply to functions and classes
- To effectively implement decorators, avoiding common implementation mistakes
- To analyze how to avoid code duplication (the ...
