Question

Please do not copy from other response this is the second time to post this question

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 stressed. I don't know how to return two students whose names are the same 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

Answer 1

Solution:

Please find below the code :

students = []

class Student:
def __init__(self, last_name, first_name, phNumber, email):
self.last_name = last_name
self.first_name = first_name
self.phNumber = phNumber
self.email = email

def getLastname(self):
return self.last_name
  
def getFirstname(self):
return self.first_name

def getPhNumber(self):
return self.phNumber

def getEmail(self):
return self.email

def setFirstname(self, first_name):
self.first_name = first

def setLastname(self, last_name):
self.last_name = last

def setPhNumber(self, phNumber):
self.phNumber = phNumber

def setEmail(self, email):
self.email = email

def __str__(self):
return self.last_name + ", " + self.first_name + " -- Phone: " + str(self.phNumber) + '\n' + "Email Address: " + self.email + '\n'

class Rolodex:
def add_student(self, st):
global students
students.append(st)
  
def lookup(self, name):
for student in students:
if(student.getLastname() == name):
print(student)

st1 = Student("Black", "John", 12345, "blackj@uscd.edu")
print(st1)
st2 = Student("White", "Ann", 35435, "whitea@rt.edu")
print(st2)
r = Rolodex()
r.add_student(Student("White", "Ann", 35435, "whitea@rt.edu"))
r.add_student(Student("Black", "John", 12345, "blackj@uscd.edu"))
r.lookup("Black")
r.lookup("White")

Output:
