The code creates a very simple/easy RPG game, with 2 classes `Jedi` and `Orc`. The data is visualized using `turtle`. Each class has a method of `attack` (`lightsaber_attack` for `Jedi`), which has an argument that must be either a `Jedi` or `Orc` instance. The `.health` attribute of the attacked one will be reduced by `.power` of the attacker. If `.health` is not positive, then the image of the character will disappear. By design, each character can attack itself.

luke.lightsaber_attack( orc_1 )
luke.lightsaber_attack( orc_2 )
orc_1.attack( luke )
orc_2.attack( orc_2 )
Questions
---
- How can I make the code to be easily understood by teenagers? (in a tutorial)
- How can I make it more compact?
- Are there any missing important features of Python's OOP that are important to be explained to students? (other than `super` and inheritance)
