Implement a function cousins(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 the names of all cousins 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 is not in the database). For example, cousins should behave as follows, after reading in the provided hobbit-family.txt file: >> hobbits = read_family('hobbit-family.txt') >> sorted(cousins('Frodo Baggins', hobbits)) ['Daisy Baggins', 'Merimac Brandybuck', 'Milo Burrows', 'Saradoc Brandybuck', 'Seredic Brandybuck']
