How to Access Child-class Methods from Parent-class in Python

This topic tells accessing child class methods from the parent class. A concept is already available to access parent class methods from child class (using the super method). Here, it is the opposite.

As part of OOPS and avoiding code repetition, you can access parent class methods from the child. Similarly, vice versa. But how? Below example explains it.

Accessing child class methods from the parent

Before deep diving into details, the relationship usually goes from parent to child. Always parent is a master, and a child is born to a parent. The child can get its parent’s methods.

Below, you will find the logic is how one can access child-class methods from the parent class. It’s also an interview question.

Child and Parent classes

Here, I have written two classes and explained how it works. And in the child class passed parent class as argument. I have now assigned the obj1 object to the parent class.

class parent:
    def __init__(self):
    def test1(self):
        print("I am in Parent")
class child(parent):
    def __init(self):
    def test2(self):
        print("I am in child class")

# Call to child-class method from parent


The below result shows an error when you try to call the child method from the parent. In interviews, you can tell you would get an Attribute error. So inheritance works from parent to child and not from child to parent.

Traceback (most recent call last):
  File "", line 15, in <module>
AttributeError: 'parent' object has no attribute 'test2'
