[Tutor] Stopping function after given time

[Johan Geldenhuys]

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 seconds and then it will terminate and there 
you can call a different function that does the rest of your stuff.
