Question

Write Python code to define a class called Student.

The Student class should have the following private fields:

1. name – to store the name of a student
2. attend – to store how many times a student attend the class
3. grades – a list of all student’s grades

The Student class should have the following methods:

1. a constructor
2. getter method for the name field
3. attendClass method: that increments the attend field (should be called every time a student attends the class).
4. addGrade method: adds a new grade to the grades list
5. __str__ method: prints all student’s information

In the same file, write a main function to test the functionality of the Student class.

Answer 1

class Student:
    def __init__(self, name='', attend=0, grades=[]):
        self.name = name
        self.attend = attend
        self.grades = grades

    def get_name(self):
        return self.name

    def attendClass(self):
        self.attend += 1

    def addGrade(self, grade):
        self.grades.append(grade)

    def __str__(self):
        result = 'Name: ' + self.name + '\n'
        result += 'Number of classes attending: ' + str(self.attend) + '\n'
        result += 'Grades are: ' + str(self.grades)
        return result


def main():
    s = Student('Ronaldo')
    s.attendClass()
    s.addGrade(97)
    s.attendClass()
    s.addGrade(92)
    print(s)


main()
