    You can simply return from your thread. (As far as it is not a Tk application.) Normally there is no need to 'kill' a thread.

      Well here is the situatian. As i mentioned the sub in the thread keeps going and my main program also keeps going.

      I want in the main process when i hit a button to stop the cycle in the thread. Is there such way. I mean maybe to use a flag in the sub(tried this it didn't reflect anything). So is there a way to end the cycle in the sub

      This is what i mean by killing it i want to stop this sub or simply execute return in it when there i a button pressed in the main process

        I did some research on this because I run chess engines which may get out of hand. I was wondering if I can kill a handler thread when the engine freezes. It is far from being natural and easy. From what I've read I gathered that 'killing' threads from the outside is a thing you should avoid. I personally use the Tk event loop for event driven programming. I only use threads for shepherding processes which are started once and run all the way long paralelly with the MainLoop. Normally there is no need to 'kill' such a thread.
