What are the benefits of using decorators in Python?

Decorators in Python allow you to modify the behavior of functions or methods. They promote code reusability, enhance readability, and can help in logging, enforcing access control, and more.

Can you give me an example of a decorator?

Sure! Here's a simple example:

def my_decorator(func):
    def wrapper():
        print("Something is happening before the function is called.")
        func()
        print("Something is happening after the function is called.")
    return wrapper

@my_decorator
def say_hello():
    print("Hello!")

say_hello()

How do decorators improve code readability?

Decorators can encapsulate functionality in a clean and concise way, allowing you to separate concerns. This makes the main logic of your code clearer and easier to understand.

Are there any downsides to using decorators?

Yes, while decorators are powerful, they can also make debugging more complex and may introduce performance overhead if not used judiciously.
