OOP - Polymorphism in Python

What does the word polymorphism literally mean in Greek?

• One shape

• Many forms

• Single type

• Multiple loops

In the given Python example, what is the name of the method used in all four classes?

• calculate()

• run()

• operate()

• execute()

Which type of polymorphism is demonstrated in the code snippet?

• Compile-time polymorphism

• Runtime polymorphism

• Static method overloading

• Function overloading

In the Divide class, what does the code do when b equals zero?

• Returns infinity

• Prints None

• Prints an error message

• Skips the operation silently

Why is polymorphism useful in the given code?

• It removes the need for loops

• It allows the same method name to have different implementations

• It automatically converts numbers to strings

• It speeds up execution time

How does the for loop in the snippet demonstrate polymorphism?

• It checks each object’s class before calling its method

• It calls operate() without caring about the object type

• It executes only the Add class method

• It prevents division by zero

What OOP principles are strongly supported by polymorphism in this example?

• Recursion and Iteration

• Abstraction and Encapsulation

• Inheritance and Compilation

• Casting and Parsing

Which of the following is NOT a benefit of using polymorphism?

• Easier code extension

• Improved maintainability

• Reduced type-checking conditions

• Increased number of if statements

In the analogy given, polymorphism is compared to:

• A Swiss army knife

• A universal remote

• A toolbox

• A smartphone

If we wanted to add a new operation, such as exponentiation, what should we do according to polymorphism principles?

• Modify all existing classes

• Create a new class with the operate() method

• Add a case statement in the loop

• Replace the for loop with multiple if statements
