Question

Class Parent:

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

instance = Child()

What is the value of ?

Answer 1

The code provided contains a class inheritance scenario in Python. The value of the missing variable after instantiation will depend on the order of statements in the Child class's __init__ method. If the variable was meant to be an instance attribute set in both classes, the final value would be as specified by the last assignment in the Child's __init__ method.

Step-by-step explanation:

The question is about a class inheritance in Python where a Child class is inheriting from a Parent class. In the given code, there is a presumed typo; the variable that holds the value is not specified. Assuming the variable is specified correctly as an instance attribute (for example, self.value), when the Child class calls super().__init__(), the Parent's __init__() method is called, and any initialization within the Parent class is executed. Therefore, if the Parent is defining an attribute with a value of 10 and the Child is defining the same attribute with a value of 40, the Child's value would initially be set to 40, but then the super().__init__() call would set it to 10. However, the order of the statements in the Child's __init__ method matters; if the super call is at the end, the value remains 40.
