How to change ipywidget animation speed during animation

I am using jupyter notebook to animate a marker that moves along an ant path. I am using ipyleaflet and ipywidgets. I have added a slider widget (speed_slider) to my map, to allow me change the speed of the animation. My animation is using a for loop code as shown in below code.

for i in ant_path.locations:
    mark.location = i
    sleep(speed_slider.value)

I am able to set the animation speed before running the cell that contains the above for loop code, but I am not able to change the speed during animation. Please any suggestions on how change the animation speed during the animation runtime, using the slider.

Thanks so much Martin. Implemented and working perfectly.

Something like the last cell of this Notebook: https://github.com/martinRenou/ipycanvas/blob/master/examples/conways_game_of_life.ipynb

So something like:

from threading import Thread

class AntPathAnimation(Thread):
    def __init__(self, ant_path, mark, speed_slider):
        self.ant_path = ant_path
        self.mark = mark
        self.speed_slider = speed_slider
        super(AntPathAnimation, self).__init__()

    def run(self):
        for i in self.ant_path.locations:
            self.mark.location = i
            sleep(self.speed_slider.value)

AntPathAnimation(ant_path, mark, speed_slider).start()
