Which of the following statements about polymorphism in Python is correct?

A:

Polymorphism is achieved through method overloading only

B:

Polymorphism is achieved through method overriding only

C:

Polymorphism is achieved through both method overloading and overriding

D:

Polymorphism is achieved through operator overloading only

Answer: C

Polymorphism in Python is achieved through both method overloading and method overriding.

What is static polymorphism?

A:

The ability of a function to take different types of arguments

B:

The ability of an object to take on multiple forms or types at runtime

C:

The ability to define custom behavior for operators in a class

D:

The ability to resolve method calls at compile-time

Answer: D

Static polymorphism in Python, also known as compile-time polymorphism, involves resolving method calls at compile-time based on the method signatures.

What is the purpose of the __getitem__() method in Python classes in the context of polymorphism?

A:

To define class attributes

B:

To customize the behavior when an instance is deleted

C:

To customize the behavior when an item is accessed using square brackets on an instance

D:

To create a new instance of the class

Answer: C

The __getitem__() method is used to customize the behavior when an item is accessed using square brackets on an instance, allowing for polymorphic behavior.

How does Python achieve polymorphism through method overloading?

A:

By allowing a function to take different types of arguments

B:

By automatically resolving conflicts using the first defined method

C:

By using the C3 linearization algorithm to determine method resolution order

D:

Python does not support method overloading

Answer: D

Python does not support method overloading in the traditional sense, where multiple methods with the same name have different parameters.

📖

Consider the following code:

class Vehicle:
    def drive(self):
        pass

class Car(Vehicle):
    def drive(self):
        return "Car is driving"

class Bicycle(Vehicle):
    def drive(self):
        return "Bicycle is pedaling"

What concept is demonstrated in this code?

A:

Method overloading

B:

Method overriding

C:

Operator overloading

D:

Polymorphism

Answer: B

This code demonstrates method overriding, where the subclasses provide specific implementations for a method defined in the superclass.
