Python - Encapsulation and Data Protection

Given this code, what is the output?

class Parent:
    def __init__(self):
        self._value = 5

class Child(Parent):
    def __init__(self):
        super().__init__()
        self._value = 10

p = Parent()
c = Child()
print(p._value, c._value)

A5 5

B10 10

C5 10

DAttributeError

Step-by-Step Solution

Solution:

Step 1: Understand attribute assignment in parent and child
Parent sets _value to 5; Child calls parent's init then sets _value to 10.
Step 2: Check instances' attribute values
Parent instance p has _value 5; Child instance c has _value 10.
Final Answer:
5 10 -> Option C
Quick Check:
Each instance has its own protected attribute value [OK]

Quick Trick: Child can override protected attribute after calling super().__init__() [OK]

Common Mistakes:

MISTAKES

Assuming parent's attribute changes child's value
Expecting both values to be same
Confusing instance attributes with class attributes
