按下tkinter上的一个按钮时，如何中断睡眠

Question

I have a sensor() method, and I use root.after(200, sensor) to run it all the time. I also have a function set_speed() in it which can set the speed of motor. When the sensor detects something, it will run

set_speed(100)
sleep(3)
set_speed(0)

Now I need to add another button, when the sensor detects something, we can press the button the break the sleep (bu the sensor is still running).

It seems that I need to add another root.after to create another thread or something, I have tried for a while but was not able to complete it.

Answer 1

Problem solved. We can simply use another after to build another thread which will be run 3 seconds later and set the speed as 0.

    set_speed(100)
    root.after(3000, stop)   

.....

def stop():
    set_speed(0)
