Implement a function grandparents (person, family) with the following specification. Input: A string containing a person's name, person, and a family tree database family as specified above. Output: A list containing only the names of the grandparents of person that are stored in the database, or an empty list if no such information exists in the database (including if the person themselves are not in the database). For example, grandparents should behave as follows: >>> duck_tree = [['Donald Duck', 'Quackmore Duck', 'Hortense McDuck'], ['Della Duck', 'Quackmore Duck', 'Hortense McDuck'], ['Hortense McDuck', 'Fergus McDuck', 'Downy ODrake'], ['Scrooge McDuck', 'Fergus McDuck', 'Downy ODrake'], ['Fergus McDuck', 'Dingus McDuck', 'Molly Mallard'], ['Huey Duck', None, 'Della Duck'], ['Dewey Duck', None, 'Della Duck'], ['Louie Duck', None, 'Della Duck']] >>> sorted (grandparents ('Scrooge McDuck', duck tree)) ['Dingus McDuck', 'Molly Mallard'] >>> sorted (grandparents ('Louie Duck', duck_tree)) ['Hortense McDuck', 'Quackmore Duck'] >>> grandparents ('Fergus McDuck', duck tree)

Implement a function grandparents (person, family) with the following specification. Input: A string containing a person's name, person, and a family tree database family as specified above. Output: A list containing only the names of the grandparents of person that are stored in the database, or an empty list if no such information exists in the database (including if the person themselves are not in the database). For example, grandparents should behave as follows: >>> duck_tree = [['Donald Duck','Quackmore Duck', 'Hortense McDuck'], ['Della Duck', 'Quackmore Duck', 'Hortense McDuck'], ['Hortense McDuck', 'Fergus McDuck', 'Downy ODrake'], ['Scrooge McDuck', 'Fergus McDuck', 'Downy ODrake'], ['Fergus McDuck', 'Dingus McDuck', 'Molly Mallard'], ['Huey Duck', None, 'Della Duck'], ['Dewey Duck', None, 'Della Duck'], ['Louie Duck', None, 'Della Duck']] >>> sorted (grandparents ('Scrooge McDuck', duck_tree)) ['Dingus McDuck', 'Molly Mallard'] >>> sorted (grandparents ('Louie Duck', duck_tree)) ['Hortense McDuck', 'Quackmore Duck'] >>> grandparents ('Fergus McDuck', duck tree) [)
