In python you define a class method (an action, event, or function) using the following structure:. Python doesn't have private anything but we still have a need to separate inners of a class from the public interface. Magic methods are not meant to be invoked directly by you, but the invocation happens internally from the class on a certain action. The class should contain: • yearModel -- The yearModel field is an int that holds the car's model year • make -- The make field is a String that holds the make of the car • speed -- The speed field is an int that holds the car's current speed.
