Decorators are a way to modify or enhance the behavior of a function or class without changing its source code.

Decorators are defined using the '@' symbol followed by the decorator name.
They can be used to add functionality to a function or class, such as logging or timing.
Decorators can also be used to modify the behavior of a function or class, such as adding caching or memoization.
Multiple decorators can be applied to a single function or class, and they are executed in the order they are defined.
Decorators can also take arguments, allowing for more customization.
Examples of built-in decorators in Python include @staticmethod, @classmethod, and @property.
