46.
How does Python achieve polymorphism through "parametric polymorphism"?
By explicitly specifying data types for objects
By using static typing to enforce object compatibility
By allowing objects to take on multiple forms based on their behavior
By defining functions or classes that can operate on different data types
Answer: Option
Explanation:
"Parametric polymorphism" in Python refers to defining functions or classes that can operate on different data types, contributing to polymorphic behavior.
47.
Which of the following is an example of polymorphism through function overriding?
Defining a function with the same name but different parameters in a module
Defining a function with the same name but different return types in a module
Defining a function with the same name in a module
Defining a function with different access modifiers in a module
Answer: Option
Explanation:
Polymorphism through function overriding in Python involves defining a function with the same name in a module, where a subclass provides a specific implementation for the function.
48.
What is the purpose of the __floordiv__() method in Python classes in the context of polymorphism?
To customize the behavior when an instance is divided using floor division by another instance
To create a new instance of the class
To define class attributes
To customize the behavior when an item is accessed using square brackets on an instance
Answer: Option
Explanation:
The __floordiv__() method is used to customize the behavior when an instance is divided using floor division by another instance, allowing for polymorphic behavior.
49.
In Python, what is the purpose of the __contains__() method?
To define class attributes
To customize the behavior when an item is checked for membership using the in keyword
To create a new instance of the class
To customize the behavior when an instance is compared using the == operator
Answer: Option
Explanation:
The __contains__() method is used to customize the behavior when an item is checked for membership using the in keyword, allowing for polymorphic behavior.

Consider the following code: 
class Animal:
    def speak(self):
        pass

class Dog(Animal):
    def speak(self):
        return "Woof!"

class Cat(Animal):
    def speak(self):
        return "Meow!"
What concept is demonstrated in this code?
Method overloading
Method overriding
Operator overloading
Polymorphism
Answer: Option
Explanation:
This code demonstrates method overriding, where the subclasses provide specific implementations for a method defined in the superclass.
