So it would be more typically Pythonic to write class Child(Parent): def __init__(self, c): Parent.__init__(self, a, b) self.C = c This allows you to pass the a and b values into the creator call in the following way: obj = Child(2, 3, 1) rather than explicitly setting attributes of the Child instance in line.

e are more pythonic ways to perform this task. You might try: for index in range(len(fruit)): letter = fruit[-index-1] print letter as one example. I'm sure other readers will have their own ways to do this, many of them more elegant. regards Steve -- Steve Holden +44 150 6

Unfortunately it also seems you would like the input thread to be terminated when the timer thread finds its time is up, and that's not particularly easy because there's no way to stop a thread "from the outside" once it's started. regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC www.holdenweb.com PyCon TX 2006 www.python.org/pycon/ -- http://mail.python.org/mailman/listinfo/python-list
