It's simple as it is.

Just make class and put vars in it like:

class <MyClass>():
    <var1> = <val1>
    ... etc

then just use it <MyClass>.<var1>

for structs it's pretty simple:

class <MyStruct>():
    def __init__(x, y, z):
        self.<any_name> = x
        ....

Script seems to work, but source looks terrible. You have to read about structs at least. It's just a pain to see avoiding OOP in languange that mostly rely on it.
