Solve the following python programming problem given the following code:
def _delete_objects(self, context, threads) : 
    'Delete objects created by Swift context and update Rally context.

        :param context: dict, Rally context environment
        :param threads: int, number of threads to use for broker pattern
        ' 
    def publish(queue) : 
        for tenant_id in context ['tenants'] : 
            containers = context ['tenants'] [tenant_id] ['containers'] 
            for container in containers : 
                for object_name in container ['objects'] [:] : 
                    args = (object_name, container) 
                    queue.append (args) 
def consume(cache, args) : 
        (object_name, container) = args 
        user = container ['user'] 
        if (user ['id'] not in cache) : 
            cache [user ['id']] = swift_utils.SwiftScenario ({ 
                'user' : user, 
                'task' : context.get ('task', { 
                    
}), 
}) 
cache [user ['id']]._delete_object (container ['container'], object_name) 
        container ['objects'].remove (object_name) 
broker.run (publish, consume, self) 

    
    

    Fix the buggy line: broker.run (publish, consume, self)

#Here is Python program to fix the buggy line: broker.

broker.run (publish, consume, threads)
