Sure, I understand. Please note that nothing is really private in python. There is nothing to prevent you from poking around inside and using various internals of a class. The pythonic idea is *'we're all consenting adults here'. *Meaning that a leading '_' implies that the author wants the variable to be private. Nothing more, nothing less. If your variables are to be used used outside the class, there is no need for making them private. But do remember, whatever you expose, WILL be used by the cosumers and they will do everything they can, to that variable. Your logic should then be strong enough to be able to handle anything that is executed by the consumers. This may or may not apply in your example case, but keep that in mind, as a guiding principle, whenever you code. This way your code will be future-proofed.

In my example code, they are globals but you can move them inside the class as well. The only reason to make them global is that other participating classes and interface functions can use them freely. Also note that, in python, classes can also acts as a namespace, Justin's code implements the `state`enums using the class as a namespace. In fact, if you look at it, a class is just like a module. The 'self' (recommened as a strong convention) is just a way to tell the methods that you are referring to this class' namespace in the instance. Otherwise, for all intents and purposes, a class can be used as a namespace or module.
