I need a python 3 help.

from question 1.2,

r.add_student(Student("White", "Kate", 78787878, "whitek@rt.edu"))

>>> r.lookup("White")

White, Ann -- Phone: 35435

Email Address: whitea@rt.edu

White, Kate -- Phone: 78787878

Email Address: whitek@rt.edu

this part got me so stressful. I don't know how to return two students whose name is white.

Part 1. Classes

Question 1.1

Define a Student class that follows the doctests below:

class Student:

"""

>>> st1 = Student("Black", "John", 12345, "blackj@uscd.edu")

>>> print(st1)

Black, John -- Phone: 12345

Email Address: blackj@uscd.edu

>>> st2 = Student("White", "Ann", 35435, "whitea@rt.edu")

>>> print(st2)

White, Ann -- Phone: 35435

Email Address: whitea@rt.edu

"""

Question 1.2

Now you can use your Student class to create an rolodex for storing contacts of your friends. Your class should allow to add new students to rolodex,

search it for a friend, and view their contact information. You need to develop a Rolodex class, its behaviur should follow the doctests below. Hint: Python's built-in dictionaries might be useful.

class Rolodex:

"""

>>> r = Rolodex()

>>> r.add_student(Student("Black", "John", 12345, "blackj@uscd.edu"))

>>> r.add_student(Student("White", "Ann", 35435, "whitea@rt.edu"))

>>> r.lookup("Black")

Black, John -- Phone: 12345

Email Address: blackj@uscd.edu

>>> r.lookup("White")

White, Ann -- Phone: 35435

Email Address: whitea@rt.edu

>>> r.add_student(Student("White", "Kate", 78787878, "whitek@rt.edu"))

>>> r.lookup("White")

White, Ann -- Phone: 35435

Email Address: whitea@rt.edu

White, Kate -- Phone: 78787878

Email Address: whitek@rt.edu
