Python 3.x battle

I am making a game. I am in the process of making a battle for my new game. However, the enemy keeps on killing the player. Please tell me what is wrong with the code. This is only one part of the battle. I will have it happen over and over again. Thank you. And sorry the some of the code is in the box and some isn't.

(This is for python 3.5.1)

I posted the code here.
