What are some practical use cases for Python decorators?

Python decorators are a powerful tool for modifying the behavior of functions or methods. Some practical use cases include logging, access control, memoization, and enforcing type checks.

Can you explain how a logging decorator works?

Sure! A logging decorator wraps a function to log its execution details, such as the function name and arguments, every time it is called.

How would I implement a simple logging decorator?

You can create a logging decorator by defining a function that takes another function as an argument, then defines an inner function that logs the details and calls the original function.

Can decorators be used with classes?

Yes, decorators can be applied to class methods as well, allowing you to modify their behavior similarly to functions.
