Define a function named create_books_ratings_dictionary (people_ratings, books_list) which takes a ratings dictionary and a book list as parameters. The function returns a new dictionary. The key of the new dictionary is the book id and the value of the new dictionary is a list of ratings for the particular book. For example, consider the following rating dictionary: people_ratings = {'Adam':[7, 2, 5],'Jo':[9, 2, 3] } Then, the ratings for the first book are [7, 9] and the ratings for the second book are [2, 2] and so on. Hence, the resulting dictionary would e: { 'BC001': [7, 9], 'BC002': [2, 2], 'BC003': [5, 3] }
