Python - Classes and Object Lifecycle

You have a class Student with attributes name and grades (a list). How do you add a new grade 95 to the student's grades list?

Astudent.grades = 95

Bstudent.append(95)

Cstudent.grades.append(95)

Dstudent.grades.add(95)

Step-by-Step Solution

Solution:

Step 1: Understand attribute type
The grades attribute is a list, so to add an item, use the list method append().
Step 2: Evaluate options
student.grades.append(95) correctly calls append(95) on the grades list. student.grades = 95 overwrites the list with an integer. student.append(95) tries to call append on the student object, which is invalid. student.grades.add(95) uses a non-existent method add on list.
Final Answer:
student.grades.append(95) -> Option C
Quick Check:
Use list append to add items = student.grades.append(95) [OK]

Quick Trick: Use list methods on list attributes, not on the object [OK]
