Python Decorator class with arguments

I have a simple Python class that I want to use to add named hooks to a program I am writing. I try to run the below code and I get the following output.

Code:

hooks = {}class hook(object):    def __init__(self, f, hook):        if hook not in hooks:            hooks[hook] = []        hooks[hook].append({"module": f.__module__, "func": f})        self.f = f    def __call__(self, *args):        f(*args)@hook("test")def testHook():    print "hi"

Output:

Traceback (most recent call last):                         File "<stdin>", line 1, in <module>                    TypeError: __init__() takes exactly 3 arguments (2 given)

How can I fix this? I am using Python 2.7
