Take the class Person.
class Person:
"""Person class"""
def __init__(self, lname, fname, addy=''):
self._last_name = lname
self._first_name = fname
self._address = addy
def display(self):
return self._last_name + ", " + self._first_name + ":" + self._address
Implement derived class Student
- In the constructor
- Add attribute major, default value 'Computer Science'
- Add attribute gpa, default value '0.0'
- Add attribute student_id, not optional
- Consider all private
- Override method display()
Test your code with the following driver:
# Driver my_student = Student(900111111, 'Song', 'River') print(my_student.display()) my_student = Student(900111111, 'Song', 'River', 'Computer Engineering') print(my_student.display()) my_student = Student(900111111, 'Song', 'River', 'Computer Engineering', 4.0) print(my_student.display()) del my_student
With the following OUTPUT:
Song, River:(900111111) Computer Science gpa: 0.0
Song, River:(900111111) Computer Engineering gpa: 0.0
Song, River:(900111111) Computer Engineering gpa: 4.0
Notes/Hints
- Ensure your derived Student class init includes the data
members from the base class
- You can use super().__init__(base,class,members,go,here)

In Python Exercise – Overriding class Address: def __init__(self, street, num): self.street_name = street self.number = num Now make a subclass of the class Address called CampusAddress that has a new attribute, office number, that can vary. This subclass will always have the street attribute set to Massachusetts Ave and the num attribute set to 77. Use the class as follows: >>> Sarina_addr = CampusAddress("32-G904") >>> Sarina_addr.office_number ’32G-904’ >>> Sarina_addr.street_name ’Massachusetts Ave’ >>> Sarina_addr.number 77
