python - Decorators with parameters?

Question

I have a problem with the transfer of variable 'insurance_mode' by the decorator. I would do it by the following decorator statement:

@execute_complete_reservation(True)
def test_booking_gta_object(self):
    self.test_select_gta_object()

but unfortunately, this statement does not work. Perhaps maybe there is better way to solve this problem.

def execute_complete_reservation(test_case,insurance_mode):
    def inner_function(self,*args,**kwargs):
        self.test_create_qsf_query()
        test_case(self,*args,**kwargs)
        self.test_select_room_option()
        if insurance_mode:
            self.test_accept_insurance_crosseling()
        else:
            self.test_decline_insurance_crosseling()
        self.test_configure_pax_details()
        self.test_configure_payer_details

    return inner_function

The syntax for decorators with arguments is a bit different - the decorator with arguments should return a function that will take a function and return another function. So it should really return a normal decorator. A bit confusing, right? What I mean is:

def decorator_factory(argument):
    def decorator(function):
        def wrapper(*args, **kwargs):
            funny_stuff()
            something_with_argument(argument)
            result = function(*args, **kwargs)
            more_funny_stuff()
            return result
        return wrapper
    return decorator

Here you can read more on the subject - it's also possible to implement this using callable objects and that is also explained there.
