[Solved] Which class design correctly encapsulates the data and behavior?# Procedural code def area_rectangle(width, height): return width * height w = 5 h = 3 print(area_rectangle(w, h)) | Python

Python - Object-Oriented Programming Foundations

You want to convert this procedural code into an object-oriented style. Which class design correctly encapsulates the data and behavior?

# Procedural code
def area_rectangle(width, height):
    return width * height

w = 5
h = 3
print(area_rectangle(w, h))

Aclass Rectangle: def __init__(self, width, height): self.width = width self.height = height def area(self): return self.width * self.height

Bclass Rectangle: def area(width, height): return width * height

Cclass Rectangle: def __init__(self): pass def area(self): return width * height

Dclass Rectangle: def __init__(self, width, height): return width * height

Step-by-Step Solution

Solution:

Step 1: Identify data and behavior to encapsulate
The procedural code uses width and height as data and area_rectangle as behavior. In OOP, these should be inside a class.
Step 2: Check class options for correct encapsulation
class Rectangle: def __init__(self, width, height): self.width = width self.height = height def area(self): return self.width * self.height stores width and height as instance variables and defines area() method using them. Other options either miss self, lack data storage, or misuse return in constructor.
Final Answer:
class Rectangle with __init__ storing width and height, and area method using them -> Option A
Quick Check:
OOP encapsulates data and behavior in class [OK]

Quick Trick: Store data in __init__, use methods for behavior [OK]
