How can I use decorators with classes in Python?

You can use decorators with classes to modify or enhance class methods or properties. Would you like an example?

Yes, please provide an example of a class decorator.

Sure! Here's a simple class decorator that adds a greeting method:

def greet_decorator(cls):
    class NewClass(cls):
        def greet(self):
            return 'Hello!'
    return NewClass

@greet_decorator
class Person:
    pass

p = Person()
print(p.greet())  # Output: Hello!`

What if I want to pass arguments to the decorator?

You can create a decorator factory that takes arguments. Here's an example:

def greet_decorator(greeting):
    def decorator(cls):
        class NewClass(cls):
            def greet(self):
                return greeting
        return NewClass
    return decorator

@greet_decorator('Hi there!')
class Person:
    pass

p = Person()
print(p.greet())  # Output: Hi there!`
