Python class instance starts method in new thread

You can subclass directly from Thread in this specific case

from threading import Threadclass MyClass(Thread):    def __init__(self, other, arguments, here):        super(MyClass, self).__init__()        self.daemon = True        self.cancelled = False        # do other initialization here    def run(self):        """Overloaded Thread.run, runs the update         method once per every 10 milliseconds."""        while not self.cancelled:            self.update()            sleep(0.01)    def cancel(self):        """End this timer thread"""        self.cancelled = True    def update(self):        """Update the counters"""        passmy_class_instance = MyClass()# explicit start is better than implicit start in constructormy_class_instance.start()# you can kill the thread withmy_class_instance.cancel()

In order to run a function (or memberfunction) in a thread, use this:

th = Thread(target=some_func)th.daemon = Trueth.start()

Comparing this with deriving from Thread, it has the advantage that you don't export all of Thread's public functions as own public functions. Actually, you don't even need to write a class to use this code, self.function or global_function are both equally usable as target here.

I'd also consider using a context manager to start/stop the thread, otherwise the thread might stay alive longer than necessary, leading to resource leaks and errors on shutdown. Since you're putting this into a class, start the thread in __enter__ and join with it in __exit__.
