Question

THIS IS A PYTHON PROGRAM

Suppose you have been provided four (4) input files that contain the names of persons who are affiliated with Clark Atlanta University in various capacities. You have been asked to write a Python program - that uses "sets" - to complete the following tasks: 1. Read the contents of each input file (students.txt faculty.txt , staff.txt , and alumni.txt D) into its own set. The variable names of the sets should be students, faculty, staff, and alumni. Your program should be able to handle any number of names in these files; the format of the files lists the names on separate lines. 2. Using the appropriate set methods to: o Display the names of all persons in all of the files. • Display the names of persons who are both students and staff. o Display the names of persons who are both faculty and alumni. Display the names of persons who are staff but not alumni. • Display the names of persons who are alumni but not staff.

Executable Code:

##open all the files give exact path of the file if there are not in the same folder
studentFile=open("student.txt",'r')
facultyFile=open("faculty.txt",'r')
staffFile=open("staff.txt",'r')
alumniFile=open("alumni.txt",'r')

##create a empty set
student=set()
faculty=set()
alumni=set()
staff=set()

##read data into the sets by using readline
##rstrip is used here to eliminate the \n in the each line
##add is used to add elemnts to list
for i in studentFile.readlines():
   student.add(i.rstrip())

for i in facultyFile.readlines():
   faculty.add(i.rstrip())

for i in staffFile.readlines():
   staff.add(i.rstrip())

for i in alumniFile.readlines():
   alumni.add(i.rstrip())
##displaying names in all the files
print("Names of student ",student)
print("Names of faculty ",faculty)
print("Names of staff ",staff)
print("Names of alumni ",alumni)

## display all names by applying union
print("All name ",student | faculty|staff|alumni)

##common in studets and staff

print("Names of the persons who are common in both student and Staff",student & staff)

##common in faculty and alumni

print("Names of the persons who are common in both student and Staff",faculty & alumni)

## people who are staff but not alumni

print("Persons who are staff but not alumni ",staff-alumni)

##people who are alumni but not staff
print("Persons who are staff but not alumni ",alumni-staff)

Sample Output:
