Movie genres represent the various categories that movies can belong to. A movie could be a comedy, a romance, a zombie film, or a romantic zombie comedy. The Movie class defines a constant tuple of genre names called GENRES . The genres for each Movie object is stored as a list of integer indexes for the GENRES constant. Thus a romantic zombie comedy would have its genres stored as [3,4,5] . This list of integers must be converted to a string for display purposes.

For example, the movie Dellamorte, Dellamore has the genre list [3,4,5,8] . It prints out as:

Title: Dellamorte Dellamore Year: 1994 Director: Michele Soavi Rating: 7.2 Genres: romance, comedy, zombie, horror 

Complete the genres_string method for the Movie class.

"""
