Question
class Parent: def init(self): self.__num=56 def show(self): print("Parent:",self.__num)class Child(Parent): def init(self): super().init() self.__var=89 def show(self): print("Child:",self.__var)parent=Parent()parent.show()child=Child()child.show()
Solution
The given code snippet is written in Python. It defines two classes, Parent and Child, and demonstrates inheritance.
Step 1: Define the Parent class The Parent class has an initializer method (init) that sets a private variable __num to 56. It also has a show method that prints the value of __num.
Step 2: Create an instance of the Parent class We create an instance of the Parent class called parent using the Parent() constructor.
Step 3: Call the show method on the parent object We call the show method on the parent object using the parent.show() syntax. This will print "Parent: 56" because the value of __num is 56.
Step 4: Define the Child class The Child class is a subclass of the Parent class. It has its own initializer method (init) that calls the initializer of the Parent class using the super() function. It also sets a private variable __var to 89. The Child class also overrides the show method of the Parent class.
Step 5: Create an instance of the Child class We create an instance of the Child class called child using the Child() constructor.
Step 6: Call the show method on the child object We call the show method on the child object using the child.show() syntax. This will print "Child: 89" because the value of __var is 89.
Overall, the code demonstrates the concept of inheritance in Python, where the Child class inherits attributes and methods from the Parent class and can also override them if needed.
