Python for OOP - The A to Z OOP Python Programming Course - Polymorphism

The video tutorial covers polymorphism, a key concept in object-oriented programming, explaining its definition and practical applications. It demonstrates polymorphism through examples of operator overloading and method overriding, using classes and objects to show how a single operator or method can have multiple forms. The tutorial concludes with a summary of polymorphism's role in programming.

What does the term 'polymorphism' mean in the context of object-oriented programming?

• A method that can only be used once

• A function that can take multiple forms

• A variable that can change its type

• A class that can inherit from multiple classes

How does the '+' operator demonstrate polymorphism?

• By multiplying numbers

• By performing both addition and concatenation

• By only concatenating strings

• By only adding numbers

What is the purpose of operator overloading in polymorphism?

• To restrict operators to a single function

• To allow operators to have different meanings based on context

• To create new operators

• To remove operators from a class

In the given code example, what is the role of the 'add' method in the phone class?

• To subtract two numbers

• To divide two numbers

• To concatenate brand and model names

• To multiply two numbers

How does the 'add' method behave differently in the flagship class?

• It adds the prices of two objects

• It concatenates the rear camera megapixels

• It multiplies the storage capacities

• It subtracts the front camera megapixels

What is the main advantage of using polymorphism in programming?

• It increases the complexity of code

• It restricts the use of functions

• It simplifies code by allowing a single interface for different data types

• It limits the number of classes in a program

Which of the following best describes polymorphism?

• A variable that changes its value

• A method that can only be used in one class

• A class that cannot be inherited

• A single method that can operate on different types
