In a previous post, I was told I am coding in Python like you would in BASIC (I am not "thinking" in Python yet). This is probably true and this is why I need help. This being said, I have read one book about Python so far (Bytes of Python), I bought two more books online (one of which is Invent with Python, which I am reading) and I did many tutorials from The New Boston. Still, my question might sound newbie-ish to you.
In FreeBasic, variables are all globalized. In Python, I have to globalize them for every single new function I create. This isn't very practical. So what am I expected to do? How would a "native Python speaker" tackle this problem? Below you'll find a small program I have created where I globalize in all my variables inside functions.

I've reorganized your program to show you the basics of object oriented programming. You need to learn about classes and objects. You should also look at string formatting for the right way to put strings together.
Basically, you create two player objects, and then create a combat object for those two players. Then, you call methods on the combat object in order to actually do the combat. self
is how an instance of a class refers to itself. Any good Python tutorial should teach you about all of these things.
The only remaining global variable is a constant, ast
. Global constants can occasionally be OK.
