Does @ at sign used for tother than decorators?

[ggpython000]

I have simple example for decorator usage which is straightforward to understand:

def print_fcn_name(func):
        def wrapper():
            print("Something is happening before the function is called.")
            func()
            print("Something is happening after the function is called.")
        return wrapper


@print_fcn_name
def f1():
    print("this is f1...")

f1()

But I am seeing what seems usage other than decorator, for example, following statement I just can not get it:
Do I see it is calling previously defined decorator function called triton.autotune?

@triton.autotune(
    configs=[
        <data definitions1>
    ] if torch.version.hip is None else [
        <data definitions2>
    ],
    key=['M', 'N', 'K'],
)

Please, use proper tags when post code, traceback, output, etc. This time I have added tags for you.
