I am having a hard time tracking and adjusting player["health"] I created a function reduce_health(): that lowers the player health based on enemy attack, but when I run a fight the health does not work. I just simply win the fight or when I edit the code it just goes back and forth attacking forever. How can I create a function the reduce health and tracks it after each attack until the player dies? Note the code may not look well structured because I'm still working on it and will clean it up after I figure this out.

So this is my second mini project in python and because I'm still learning I'm using reference code and asking questions to make the project, but I keep getting an error "Undefined variable 'player_damage'" on line 49-52.

I am using Ghostscript under Linux, and still feel like a newbie. I want to save the value on top of the stack so that I can recall the value later without having to do complex stack operations to retrieve it. The value will be a latitude read from a data file so I cannot incorporate it direct;y in the program. The obvious solution seems to me to store the value as a key/value pair in the userdict, something like (to save a latitude value):
