Re: [Tutor] Stopping function after given time

You can use the Timer in threading. Look at what is done in the attached script. You can basically use three functions to start the timer, stop the timer and do what ever it is to be done upon expiring. There maybe easier ways, but this will work. You can call the start_timer with a time in se
