Python - Encapsulation and Data Protection

Find the error in this code that tries to create a public attribute age:

class Person:
    def __init__(self, age):
        age = age

p = Person(30)
print(p.age)

AThe attribute should be assigned to self.age, not age

BThe print statement should be print(age)

CThe constructor is missing a return statement

DThe class name should be lowercase

Step-by-Step Solution

Solution:

Step 1: Check attribute assignment
Assigning age = age only creates a local variable, not an attribute of the object.
Step 2: Correct attribute assignment
It should be self.age = age to create a public attribute accessible outside.
Final Answer:
The attribute should be assigned to self.age, not age -> Option A
Quick Check:
Use self.attribute = value to create public attribute [OK]

Quick Trick: Always assign attributes to self.attribute inside __init__ [OK]
