python text adventure

ok, so im working on this text adventure, and i want it to be so that my script for being attacked will be able to used at any point. like function except i know thats wrong or i am doing somethign wrong. how do i define a script for future use in python? everytime i try it says some bullcrap about the variables not existing?

It's called a module you big dummy.

import attack-script

then

attack-script.attack() <- for functions
