 I firstly apologise for multiple posts and thanks for the reply  . I
was actually in hurry to complete my assignment  and there was no way
to figure out what was going wrong !!

 My assignment  was to write a subroutine that run itself every n
minutes  and terminate before the main thread completes.

  I thought threading.Timer helped me achieve this  but timer.cancel()
didn't help me terminate the timer .

Thanks for the above  hint, I will try this and get back to you

Sure will keep this in mind
