Python Heads或Tails游戏，不显示除了子句

I am currently working on a Heads or Tails game. So It loops till the health gets to 0 but when it gets to 0 its suppose to break out of the try except loop. But when it gets to the end it just displays "Sadly, thats not the right side!" and then just stops... No clue why any help is greatly appreciated.I am currently working on a Heads or Tails game
