How to properly subclass a subclass of Python Thread?

Question

I have two classes: ContinuousWorker and WorkerA. I would like to pass in an argument that is specific to WorkerA, but also still be able to pass in Thread configuration arguments for use in the the thread.__init__() function. How can I do this?

import threading

class ContinuousWorker(threading.Thread):
    def __init__(self, *args, **kwargs):
        super().__init__(args, kwargs) #=> this returns Error: assert group is None, "group argument must be None for now"
        # self.Thread.__init__(args, kwargs) #=> this returns Error: 'WorkerA' object has no attribute 'Thread'

class WorkerA(ContinuousWorker):
    def __init__(self, argument, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.argument = argument

if __name__ == "__main__":
    child_class_specific_argument = 1
    worker = WorkerA(child_class_specific_argument, thread_name = "threadA", daemon = True)

EDIT: It appears the following is a working solution, can anyone confirm if there is a more pythonic way of doing this?

import threading
class ContinuousWorker(threading.Thread):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

class WorkerA(ContinuousWorker):
    def __init__(self, argument, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.argument = argument

if __name__ == "__main__":
    child_class_specific_argument = 1
    worker = WorkerA(child_class_specific_argument, name = "threadA", daemon = True)
