Question

please help me with this python code thank you

1. Write a Student class that stores information for a Rutgers student. The class
should include the following instance variables: (10 points)
o id, an integer identifier for the student
o lastName, a string for the student's last name
o credits, an integer representing the number of course-credits the
student has earned
o courseLoad, an integer representing the current number of credits in
progress
Write the following methods for your Student class:
o A constructor __init__ that, given an id, and a name, creates a Student
with those values and zero course-credits and zero course load.
o A __str__ which prints out students ID, Last name, credits and course
load.
o A registerCurrent(X) method that add X credits to the course load. The
course load need to be must be positive and no greater than 18 credits,
otherwise no change happens.
o A withdraw(X) method, which decreases the course load by X credits.
X has to be positive and courseload cannot be below 0.
o A passedCourse(X) method, which removes X credits from the current
courseload and adds to the students credits variables. X cannot be
negative, and cannot be less than the courseload.
o A createEmail() method, which print a string. The string should be an
email address of the student's name combined with their ID and
remainder of @rutgers.edu. For example, a student with last name
"Soni", and ID 25 should return "[email protected]"

Please show all of the 6 parts successfully running in order to earn your points. You
may need to demonstrate repeatedly so show all functionality.

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

#code

class Student:
    #constructor taking id and name
    def __init__(self,id,name):
        self.__id=id
        self.__name=name
        self.__credits=0
        self.__courseLoad=0

    #returns string containing id, name, credits and course load
    def __str__(self):
        return 'ID: '+str(self.__id)+', Name: '+self.__name+', Credits: '+str(self.__credits)+\
               ', Course Load: '+str(self.__courseLoad)

    #adds X to __courseLoad
    def registerCurrent(self,X):
        #X must be positive and X+__courseLoad <=18
        if X>0 and (X+self.__courseLoad)<=18:
            self.__courseLoad+=X

    #subtracts X from __courseLoad
    def withdraw(self, X):
        #X must be positive and __courseLoad-X should not go negative
        if X>0 and X<=self.__courseLoad:
            self.__courseLoad-=X

    #subtracts X from __courseLoad and adds to __credit
    def passedCourse(self, X):
        if X > 0 and X <= self.__courseLoad:
            self.__courseLoad-=X
            self.__credits+=X

   #creates and returns the email id
    def createEmail(self):
        return self.__name+str(self.__id)+'@rutgers.edu'



#main method for testing
def main():
    #creating a Student with ID 123 and name Oliver
    s=Student(123,'Oliver')
    #printing student details using __str__()
    print('Actual: ',s)
    #printing expected values
    print('Expected: ID: 123, Name: Oliver, Credits: 0, Credit Load: 0')
    print() #line break

    #adding 4 to current course load, displaying actual and expected values
    s.registerCurrent(4)
    print('Actual: ', s)
    print('Expected: ID: 123, Name: Oliver, Credits: 0, Credit Load: 4')
    print()

    # adding -3 to current course load, should make no changes
    s.registerCurrent(-3)
    print('Actual: ', s)
    print('Expected: ID: 123, Name: Oliver, Credits: 0, Credit Load: 4')
    print()

    # adding 100 to current course load, should make no changes
    s.registerCurrent(100)
    print('Actual: ', s)
    print('Expected: ID: 123, Name: Oliver, Credits: 0, Credit Load: 4')
    print()

    # withdrawing 1 from course load, should change
    s.withdraw(1)
    print('Actual: ', s)
    print('Expected: ID: 123, Name: Oliver, Credits: 0, Credit Load: 3')
    print()

    # withdrawing 2 from course load and add 2 to credits, should change
    s.passedCourse(2)
    print('Actual: ', s)
    print('Expected: ID: 123, Name: Oliver, Credits: 2, Credit Load: 1')
    print()

    #displaying actual and expected email id created
    print('Actual: ', s.createEmail())
    print('Expected: [email protected]')


#running main()
main()

#output
