Can decorators take arguments?

Can decorators in Python take arguments?

Yes, decorators can take arguments. You can define a decorator that accepts parameters by creating a function that returns a decorator.

Can you give me an example of a decorator that takes arguments?

Sure! 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}!')

What happens if I don't pass any arguments to the decorator?

If you don't pass any arguments, the decorator will not function as intended. It may raise an error or not behave as expected.
