 Study the done article, and try to improve the question - but looking at the code, even without knowing the message you see, the wrong thing is that the    _init_     method should be    __init__     (with two underscores the prefix and in the suffix) - to have the effect that you probably intend: that is, it is automatically called by the language when the    Point3D     class is instantiated. 

 It is a language convention, all methods that will be called by internal language mechanisms are surrounded by two sublinohdos    __     on each side.
