Question

                    Implement function lookup() that implements a phone book lookup application. Your functiontakes, as input, a dictionary representing a phone book. Int the                     dictionary, tuples containing first and last names of individual (the keys) are mapped to strings containing phone numbers(the values)                 

                    Your function should provide a simple interface through which a user can enter the first and last names of an individual and obtain the phone number asiigned                     to that individual.                 

                                     You must take into consideration that more than one person can have the same first and last name. A modified dictionary that maps a tuple to a list of phone                     numbers could be used to implement a more realistic phone book.
