In turn, the class Car is again an object and as such an instance of the metaclass of Car called Car class. Write a class named Car that has the following data attributes: • _ _year_model (for the car’s year model) • _ _make (for the make of the car) • _ _speed (for the car’s current speed) The Car class should have an _ _init_ _ method that accepts the car’s year model and make Instead of writing code separately for each car we could create a class called 'Car' that will be the blueprint for each particular car. The first line above makes all the types of object of Zelle’s module accessible, as if they were already defined like built-in types str or list. strong you can’t touch this policy.
