In this assignment you will modify the Department and Student Classes in A3 to use inheritance. Specifically, a generic Person' class will be created to hold basic things about named "Faculty', will be created as subclasses to Person. Person will have the following attributes and methods: a person. The Student class, and a new class a a Attribute Definition ' number identifier individual's name individual's address individual's telephone number individual's email address str num naime address telephone emai str str Method Name Purpose Input See above(a None Output/returns Constructor - sets initial attribute values in above table Displays a readable version of Person: None Person data as a Person: g num name +address ntable strin True if g num and name match, otherwise False samePerson Compares "self" Person's g num and name Person with the input Person object returns True if object match, otherwise returns False Student and Faculty will inherit the above and be defined as follows Student: inherits all Person attributes, but adds status, major, enrolled, credits, and qpoints (same as A2) Faculty: inherits all Person attributes, but adds rank, active, teach_load, specialty, funding Student and Faculty both inherit the new samePerson method that does exactly what sameStudent does, except for a generic Person object Student uses the Person constructor, but adds its own attribute definitions as defined in A2, specifically major, enrolled, credits, and qpoints Faculty uses the Person constructor, but adds its own attribute definitions as follows a@ Attribute T ran active teach load str str int str int Definition valid: {Professor, Associate Professor, Assistant Professor, Instructor) is the faculty member active? n number of credit hours taught valid: teaching, research, administration, combination dollar amount of supported research, range 0 to 10 million ear, range 0 to 24 ia fundin Student and Faculty both override the str method as follows: Student returns the string 'Student: *+g num name status+major Faculty returns the string 'Faculty:name+rank + specialty Department must be modified to track the roster of students and faculty and implement a separate addFaculty method. It will also use the samePerson) method instead of sameStudent(). It is permissible to define two rosters, one each for faculty and students, and an addFaculty method apart from the addStudent method. However, use your best judgment as to how to implement these. The 'printRoster' method can be made generic by adding a parameter, 's'orf, to determine which roster to print
