I like right2clicky's answer, especially in that it doesn't require a Thread to be torn down and a new one created every time the Timer ticks. In addition, it's an easy override to create a class with a timer callback that gets called periodically. That's my normal use case:

class MyClass(RepeatTimer):
    def __init__(self, period):
        super().__init__(period, self.on_timer)

    def on_timer(self):
        print("Tick")


if __name__ == "__main__":
    mc = MyClass(1)
    mc.start()
    time.sleep(5)
    mc.cancel()
