Question

For Python 3.7+.

In this assignment you are asked to write a Python program to define a class to model the characteristics of a university student. The class is part of a slightly larger program that includes code to use the class to create some student objects and test its methods. The name of the class is 'Student' and includes the following methods and attributes: Input/parm See below@ Output/returns None None Student data as a printable string gpa (float) gpa None Method Name Purpose _init__. Constructor - sets initial attribute values. name is a positional attribute, the others are keyword with default values. g num is generated as described in the next table. str_ Displays a readable version of the Student object Calculates and returns the student's gpa. gpa =qpoints / credits isEnrolled Returns whether the student is currently enrolled. (“y' = True, 'n' = False) status Computes class status based on # of credits completed (90+ = 'Senior', 60+ = 'Junior', 30+ = 'Sophomore', <30 = 'Freshman' sameStudent Compares "self" ("this") student's g num and name with the input Student object's - returns True if match, otherwise returns False None True or False None String indicating class status ("Senior', etc.) True or False Student object Attribute totalEnrollment g_num Type int str name major enrolled credits gpoints Definition Counts number of student objects created for entire class 6 digit Student ID: "G" + <some #zeroes> + totalEnrollment at the time the student object was created - assigned by the class Student name – “<last name>, <first name" {"Acctg", "Art", "CSci", "Hist", "IST", "Math", "Physics"} Is this a currently enrolled student? {"ty", "n"} Number of accumulated credits to date Number of accumulated quality points to date str str float float @The class definition contains a constructor whose signature line looks similar to the following line. The parameters (in parentheses) are the input data to the method. 'name' is a positional parameters and therefore must be listed first in order. The rest are keyword parameters. def __init__(self, name, major = 'IST', enrolled = 'y', credits = 0, qpoints = 0): The code that creates a student object looks similar to this: sl=Student('Fillmore, Sonia', major ="Math', enrolled = 'y', credits = 90, qpoints = 315)

TEST THE CODE WITH THE FOLLOWING GLOBAL CODE AFTER YOU'RE DONE:

print('\nStart of A2 Student class demo ')

s1 = Student('David Miller', major = 'Hist',enrolled = 'y', credits = 0, qpoints = 0)
s2 = Student('Sonia Fillmore', major = 'Math',enrolled = 'y', credits = 90, qpoints = 315)
s3 = Student('A. Einstein', major = 'Phys',enrolled = 'y', credits = 0, qpoints = 0)         
s4 = Student('W. A. Mozart', major = 'Mus',enrolled = 'n', credits = 29, qpoints = 105)
s5 = Student('Sonia Fillmore', major = 'CSci',enrolled = 'y', credits = 60, qpoints = 130)
s5.g_num = s2.g_num
s6 = Student('Pierre Renoir', major = 'Art',enrolled = 'y', credits = 120, qpoints = 315)
print('s1 = ', s1)
print('s2 = ', s2)
print('s3 = ', s3)
print('s4 = ', s4)
print('s5 = ', s5)
print('s6 = ', s6)
print('\nTotal number of students: ', Student.totalEnrollment)
print('The gpa of ', s1.name, ' is ', s2.gpa())
print('Class standing of ', s4.name, ' is ', s4.status())
print('Class standing of ', s2.name, ' is ', s2.status())
if s1.sameStudent(s2):
   print (s1.name, ' and ', s2.name, ' are the same student')
else:
   print (s1.name, ' and ', s2.name, ' are not the same student')
if s2.sameStudent(s5):
   print (s2.name, ' and ', s5.name, ' are the same student')
else:
   print (s2.name, ' and ', s5.name, ' are not the same student')
if s1.isEnrolled():
   print (s1.name, ' is currently enrolled')
else:
   print (s1.name, ' is not currently enrolled')
if s4.isEnrolled():
   print (s4.name, ' is currently enrolled')
else:
   print (s4.name, ' is not currently enrolled')
print('\nEnd of A2 Student class demo')
