10. Create a Class Named Student with Attributes; Add and Remove an Attribute and Display the Attributes

Write a Python class named Student with two attributes student_id, student_name. Add a new attribute student_class and display the entire attribute and the values of the class. Now remove the student_name attribute and display the entire attribute with values.

Sample Solution:

Python Code:

class Student:
    student_id = 'V10'
    student_name = 'Jacqueline Barnett'  
print("Original attributes and their values of the Student class:")
for attr, value in Student.__dict__.items():
    if not attr.startswith('_'):
        print(f'{attr} -> {value}')
print("\nAfter adding the student_class, attributes and their values with the said class:")
Student.student_class  = 'V'
for attr, value in Student.__dict__.items():
    if not attr.startswith('_'):
        print(f'{attr} -> {value}')
print("\nAfter removing the student_name, attributes and their values from the said class:")
del Student.student_name
#delattr(Student, 'student_name')
for attr, value in Student.__dict__.items():
    if not attr.startswith('_'):
        print(f'{attr} -> {value}')

Sample Output:

Original attributes and their values of the Student class:
student_id -> V10
student_name -> Jacqueline Barnett

After adding the student_class, attributes and their values with the said class:
student_id -> V10
student_name -> Jacqueline Barnett
student_class -> V

After removing the student_name, attributes and their values from the said class:
student_id -> V10
student_class -> V
