Question

• A cell phone has the ability to save contact information. In this assignment, you will simulate the contact list for a very simple cell phone.
• Download lab8.py below, rename it according to the instructions above, and make sure you understand it.
• Take the program above and modify it by adding the missing Contact class such that when the program is run, it produces this output.
• Hint: for help on formatting output, revisit the online textbook's chapter 9.5.1

Grading - 10 points

• 2 points - The constructor of the Contact class is correct.
• 2 points - The reader methods of the Contact class are correct.
• 2 points - The writer methods of the Contact class are correct.
• 2 points - The print_entry method of the Contact class is correct.
• 2 points - Your program's output matches the output format of the transcript above (1 point for each type of difference up to 2 points).

This is the provided lab8.py:

president = MSUContact("first4", "last4", "###-###-####")
  
contacts = [prof_892, mascot, director_CS, president]
print_directory(contacts)

mascot.set_first_name("Champ")
  
prof_892.set_title("Instuctor")
director_CS.set_title("Director")
president.set_title("President")

print_directory(contacts)
  
contact = prof_892
print(contact.get_first_name() + "'s MSU phone line is", \
contact.get_line_number())

# -----------------------------------------------------

main()

This is the provided output, with numbers altered, but formatted the same:

MSU Contacts:
----------------------------------------
first1 last1                ###-###-####
first2 last2                ###-###-####
first3 last3                ###-###-####
first4 last4                ###-###-####
----------------------------------------

MSU Contacts:
----------------------------------------
Instuctor first1 last1      ###-###-####
Champ Bobcat                ###-###-####
Director first3 last3       ###-###-####
President first4 last4      ###-###-####
----------------------------------------

first1's MSU phone line is ####

In censorship of names and numbers, I hope the intent of the code was not lost. I need to create a class of some sort to create the intended output.

Answer 1

As per given question description, here is the required source code for solution in text and image format:

Text:

class MSUContact:
def __init__(self,fname,lname,number):
self.fname = fname
self.lname = lname
self.number = number
self.title = None

def set_first_name(self,fname):
self.fname=fname
  
def set_title(self,title):
self.title = title
  
def print_entry(self):
if self.title==None:
print(self.fname+" "+self.lname+"\t"+self.number)
else:
print(self.title+" "+self.fname+" "+self.lname+"\t"+self.number)
  
def get_first_name(self):
return self.fname

def get_line_number(self):
return self.number
  
def print_directory(contacts):
print("MSU Contacts:")
print("----------------------------------------")
for person in contacts:
person.print_entry()
print("----------------------------------------\n")

def main():
prof_892 = MSUContact("first1", "last1", "###-###-####")
mascot = MSUContact("first2", "last2", "###-###-####")
director_CS = MSUContact("first3", "last3", "###-###-####")
president = MSUContact("first4", "last4", "###-###-####")
  
contacts = [prof_892, mascot, director_CS, president]
print_directory(contacts)
  
mascot.set_first_name("Champ")
  
prof_892.set_title("Instuctor")
director_CS.set_title("Director")
president.set_title("President")
  
print_directory(contacts)
  
contact = prof_892
print(contact.get_first_name() + "'s MSU phone line is", \
contact.get_line_number())

main()
