Python - Classes and Object Lifecycle

Given this class:

class Book:
    def __init__(self, title, author):
        self.title = title
        self.author = author

book1 = Book("1984", "Orwell")
book2 = Book("Animal Farm", "Orwell")

# Change author of book2 to "George Orwell"

Which code correctly updates book2 author without affecting book1?

Abook2["author"] = "George Orwell"

BBook.author = "George Orwell"

Cbook2.author = "George Orwell"

Dbook1.author = "George Orwell"

Step-by-Step Solution

Solution:

Step 1: Understand instance vs class attributes
Changing book2.author modifies only that instance's attribute, not book1.
Step 2: Avoid changing class attribute or other instance
Assigning Book.author changes class attribute for all instances; changing book1.author affects wrong object; brackets are invalid syntax.
Final Answer:
book2.author = "George Orwell" -> Option C
Quick Check:
Set instance attribute with dot on correct object = book2.author = "George Orwell" [OK]

Quick Trick: Assign attribute on specific object with dot notation [OK]

Common Mistakes:

Changing class attribute instead of instance attribute
Modifying wrong object's attribute
Using brackets instead of dot notation
