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 a person. The Student class, and a new class named Faculty', will be created as subclasses to Person. Person will have the following attribules and Attribute Definition number identifier individual's name individual's address individual's t individual's email address str one number email str Method Name Pu Output/returns Constructor sets initial attribute values in above table Displays a readable version of Person: Person: +g num+name + address inst See Person data as a ble strin samePerson "self Person's g num and name Person True if g num and ompares with the input Person object-returns True if match, otherwise returns Fal object name match, otherwise 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 same Student 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: Type str str int str aAttr Definition rank teach load fund in valid: Professor, Associate Professor, Assistant Professor, Instructor the faculty member active number of credit hours ta valid: teach dollar amount of s range 0 to 24 research, administration, combination re search, range 0 to 10 million Student and Faculty both override the tr method as follows: Student returns the string Sudent:g num+name+status +major Faculty retums 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 sameStudentO 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'or, to detemine which roster to print
