Question

Class Parent:

def __init__(self):
= 10
class Child(Parent):
def __init__(self):
= 40
instance = Child()

What is the value of ?

Answer 1

After correcting the code, the Child class overrides the Parent's __init__ method and sets the 'value' to 40. When an instance of Child is created, the 'value' of that instance will be 40.

Step-by-step explanation:

The question is examining a fundamental concept of object-oriented programming in Python: inheritance and the constructor method __init__(). The code provided aims to create a Parent class and a Child class that inherits from it. However, there are syntax errors in the code, specifically missing 'self' keywords and the variable assignment is not complete. Assuming that the intention is to assign a value to an instance variable, the code can be corrected as follows:

class Parent:
def __init__(self):
self.value = 10

class Child(Parent):
def __init__(self):
super().__init__()
self.value = 40

instance = Child()

In the corrected code, the Child class overrides the Parent's __init__ method and sets the instance variable 'value' to 40. Due to this, the value of 'instance.value' after creating an object of Child would be 40.
