Python: Add and remove attribute in a given class
Python Class ( Basic ): Exercise-10 with Solution
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 their values of the said 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

The Zip() Function:
>>> students = ('John', 'Mary', 'Mike') >>> ages = (15, 17, 16) >>> scores = (90, 88, 82, 17, 14) >>> for student, age, score in zip(students, ages, scores): ... print(f'{student}, age: {age}, score: {score}') ... John, age: 15, score: 90 Mary, age: 17, score: 88 Mike, age: 16, score: 82 >>> zipped = zip(students, ages, scores) >>> a, b, c = zip(*zipped) >>> print(b) (15, 17, 16)
