What are some advanced decorator techniques?

Can you explain some advanced decorator techniques in Python?

Sure! Advanced decorators can include class decorators, decorators with arguments, and chaining decorators. Would you like to dive into one of these?

Yes, tell me more about decorators with arguments.

Decorators with arguments allow you to pass parameters to the decorator itself. This is useful for customizing behavior. For example, you can create a decorator that logs messages with different log levels.

Can you show me an example of such a decorator?

Absolutely! Here's a simple example:

def log(level):
    def decorator(func):
        def wrapper(*args, **kwargs):
            print(f'[{level}] Calling {func.__name__}')
            return func(*args, **kwargs)
        return wrapper
    return decorator

@log('INFO')
def my_function():
    print('Function is running!')

That's really helpful! What about chaining decorators?

Chaining decorators means applying multiple decorators to a single function. They are applied from the innermost to the outermost. Would you like to see an example of that?
