If not, the `Timer` class itself will store the flag and the `_on_timer` method should be overridden to support such behavior. * `_timer_set_interval`: Code for setting the interval on the timer, if there is a method for doing so on the timer object. * `_on_timer`: This is the internal function that any timer object should call, which will handle the task of running all callbacks that have been set. Attributes: * `interval`: The time between timer events in milliseconds. Default is 1000 ms. * `single_shot`: Boolean flag indicating whether this timer should operate as single shot (run once and then stop).
