16 Questions
What is the meaning of the word 'POLYMORPHISM' in Greek?
Many forms
Method Overloading is directly supported in Python.
True
What is the purpose of Method Overriding?
To change or extend the behavior of an inherited method.
There are two types of Polymorphism: (1) _______________________, (2) _______________________.
Overloading, Overriding
What is required for Method Overriding?
All of the above
Method Overloading requires a class hierarchy.
False
What is the difference between Method Overloading and Method Overriding?
Method Overloading allows different ways to call a method with different parameters, while Method Overriding is used to change or extend the behavior of an inherited method.
Match the following concepts with their definitions:
Polymorphism = Many forms Method Overloading = Defining multiple methods with the same name but different signatures Method Overriding = Changing or extending the behavior of an inherited method
Which of the following best describes the concept of Polymorphism in Python?
Defining methods in the child class with the same name as defined in their parent class
Which type of Polymorphism is used to change or extend the behavior of an inherited method?
Method Overriding
What is the primary purpose of Method Overloading?
To allow different ways to call a method with different parameters
Which of the following statements is true about Method Overriding?
It requires a class hierarchy and must have the same name and parameters as the method in the superclass
Which of the following is a characteristic of Method Overloading?
It can have different parameters and is used to allow different ways to call a method
What is the main difference between Method Overloading and Method Overriding?
Method Overloading is used to allow different ways to call a method, while Method Overriding is used to change or extend the behavior of an inherited method
Which of the following statements is false about Method Overloading?
Method Overloading requires a class hierarchy
Which of the following is a characteristic of both Method Overloading and Method Overriding?
They both are used to change or extend the behavior of a method
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).
