What are some advanced decorator techniques in Python?

Advanced decorator techniques in Python include class decorators, decorators with arguments, and chaining decorators. Would you like to explore one of these?

Can you explain how to create a decorator with arguments?

Sure! A decorator with arguments is a function that returns a decorator. You define a function that takes parameters and then returns a wrapper function. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

def repeat(num_times):
    def decorator_repeat(func):
        def wrapper(*args, **kwargs):
            for _ in range(num_times):
                func(*args, **kwargs)
        return wrapper
    return decorator_repeat

@repeat(3)
def greet(name):
    print(f'Hello, {name}!')

# Calling greet('Alice') will print 'Hello, Alice!' three times.

That's great! How about chaining multiple decorators?

Chaining decorators is straightforward. You simply stack them on top of each other. Each decorator wraps the function returned by the previous one. Would you like to see an example of that?
