How can I implement the decorator pattern in Python?

The decorator pattern allows you to add behavior to individual objects dynamically. Would you like a code example?

Yes, please provide a simple code example.

Sure! Here's a basic example:

def decorator_function(original_function):
    def wrapper_function():
        print('Wrapper executed before {}'.format(original_function.__name__))
        return original_function()
    return wrapper_function

@decorator_function
def display():
    print('Display function executed')

display()

This will print a message before executing the display function.

What are some practical use cases for decorators?

Decorators are great for logging, enforcing access control, instrumentation, and caching results.
