For Python 3.7+.
Step 1: Copy and paste the following code. This will be your basis to do the assignment:
class Student:
# class variable to track the number of student object created totalEnrollment=0
# constructor to initialize the object def __init__(self,name,major='IST',enrolled='y',credits=0,qpoints=0):
# incrementing the class variable Student.totalEnrollment+=1 self.name=name self.major=major self.enrolled=enrolled self.credits=credits self.qpoints=qpoints self.g_num="G0000"+str(Student.totalEnrollment)
# method to calculature GPA def gpa(self):
try: return self.qpoints/self.credits except ZeroDivisionError : return 0
# method to provide the string representation of the object def __str__(self):
return self.name+", "+self.g_num+", "+self.status()+", "+\ self.major+", active: "+self.enrolled+" , credits = "+\ str(self.credits)+", "+'%.2f' % self.gpa()
# method to check whether the student is enrolled or not def isEnrolled(self):
if self.enrolled == 'y': return True elif self.enrolled == 'n': return False else: pass
# method to get the student status based on the credits def status(self):
if self.credits 30 and self.credits =60 and self.credits =90: return "Senior" else: pass
# method to check the whether current student object is # same as the other student object by comparing the g_num def sameStudent(self,other):
if self.g_num == other.g_num: return True else: return False
Step 2: Use the code above to do the following:
In this assignment you are asked to write a Python program to define a class to model some characteristics of a university Department. Specifically, the class will track students requesting to major in that particular department. Students will be represented by student objects created using the Student class developed in A2. When an attempt is made to add the student to a department's major (program), the Department class will examine the Student object data and decide whether to add them to the major. If not, the class returns a response indicating rejection with a short reason why. The Department class should have, at minimum, the following methods (you may add others): Output/returns None Method Name Purpose Input _init_ Constructor - sets initial attribute values. See d code and d name are positional attributes, below@@ the others are keyword with default values str_ Displays a readable version of the Department None object addStudent Adds qualified students to the Department Student object's roster of majors.

Create three Department class objects as described above (one per department) and include the Student class from A2 to create student objects. Create a setMajor method for Student so the Department class object can update it when a student object is successfully added to the major. 2. Within the program, use the assignment operator to create and print enough student objects to test and demonstrate the Department class capabilities. Probably 8-12 students are adequate. At least one set should completely fill a department capacity so the over capacity' rejection capability can be exercised. 3. Add each of the created students into one of the three Department class objects using the addStudent method 4. Attempt to add a student to a Department object that is already on that Department's roster. 5.
