Can someone please tell me what I am doing wrong with this loop. I want to end the loop when either one of the tanks armour reaches zero. Also if I wanted to add more tanks how can I have the loop end? Thanks

Change

``while [(t1.arm==0) or (t2.arm==0)]:``

to

``while (t1.arm > 0) or (t2.arm > 0):``
