Python - Encapsulation and Data Protection

What will be the output of this code snippet?

class Rectangle:
    def __init__(self, width, height):
        self._width = width
        self._height = height

    @property
    def area(self):
        return self._width * self._height

r = Rectangle(3, 4)
print(r.area)

AError: area is not callable

B7

CNone

D12

Step-by-Step Solution

Solution:

Step 1: Calculate area property value
The area property returns self._width * self._height, which is 3 * 4 = 12.
Step 2: Understand property access
Since area is a property, r.area returns 12 without parentheses.
Final Answer:
12 -> Option D
Quick Check:
Property returns calculated value without () [OK]

Quick Trick: Property returns computed value accessed like attribute [OK]

Common Mistakes:

Trying to call property with parentheses
Confusing area with sum instead of product
Expecting error due to missing setter
