Media class The Media class will be the abstract base class to be inherited by our Song, Movie and Picture classes. All Media objects should have a name and a rating. The rating is an integer number (think of this as the number of stars given). We will leave many design decisions to you, however you should implement at least the following methods: __init__(name, rating): Where name is a string and rating is an integer. getName() Returns the name of the Media as a string __str__(): Returns a string representation of a generic Media object in the format <>: <>, <> stars. getRating(): Returns the rating as an integer. setRating(value): Takes an integer parameter, and changes the rating of the object.
