7. group_friends_by_food For this problem, you are given a mostly-working version of the Friend and FriendsDB classes from hw6 and hw7, and we will add new method to FriendsDB -- group_friends_by_food. group_friends_by_food returns a dictionary mapping from each of the favorite foods enjoyed by any friend to a list of the friends who enjoy that food, sorted in alphabetical order. (You can use the friends_who_love method to generate these lists.) A sample run should look like this: >>> friend1 - Friend("sarah", 165) >>> friend1.add favorite food("strawberries") >>> friend2 Friend("dweezil" 175) >>> friend2.add favorite food ("pizza") >>> friend3- Friend ("bimmy" 60) >>> friend3.add favorite food("pizza") >>> friend3.add favorite food ("strawberries"). >>> db = FriendsDB() >>> db.add friend(friend1) >>> db.add friend(friend2) >>> db.add friend(friend3) >>> db.group_friends_by_ food() {'strawberries'; ['bimmy', 'sarah'], 'pizza': ['bimmy', 'dweezil']}
