Which of the following statements about Polymorphism is true?
It is a feature that allows us to define methods in the child class with the same name as defined in their parent class.

When a class wants to define methods with the same name as defined in their parent class.
Study Notes
Polymorphism
- Polymorphism comes from the Greek words "POLY" and "MORPHISM", meaning "many forms".
- It is an important feature in Python that allows defining methods in a child class with the same name as in their parent class.
Types of Polymorphism
- There are two types of Polymorphism:
- Method Overloading
- Method Overriding
Method Overloading
- Defining multiple methods in the same scope (usually in the same class) with the same name but different signatures (number or type of parameters).
- Purpose: To allow different ways to call a method with different parameters.
- Characteristics:
- Must have the same method name but different parameters.
- Does not require inheritance.
- Usually within the same class.
Method Overriding
- Subclass provides a specific implementation of a method already defined in its superclass.
- Purpose: To change or extend the behavior of an inherited method.
- Characteristics:
- Must have the same name and parameters as the method in the superclass.
- Requires a class hierarchy (inheritance).
