1. What is object-oriented programming (OOP) and how does it differ from procedural programming?

(A) OOP organizes code into objects, while procedural programming uses a sequence of steps

(B) OOP is faster than procedural programming

(C) OOP does not use functions, while procedural programming does

(D) OOP cannot be used in Python

2. Explain the concept of a class in Python. How is it defined, and what is its purpose?

(A) A class is a function that performs a specific task

(B) A class is a blueprint for creating objects and is defined using the class keyword

(C) A class is a variable that holds data

(D) A class is a module in Python

3. Describe the concept of an object in Python. How do objects relate to classes?

(A) Objects are the instances of classes created using the class definition

(B) Objects are global variables in a class

(C) Objects are the methods of a class

(D) Objects are the same as classes

4. What is encapsulation in OOP? How does Python achieve encapsulation?

(A) Encapsulation is hiding the implementation details; Python achieves it using private attributes

(B) Encapsulation is combining multiple classes into a single module

(C) Encapsulation is making attributes and methods public

(D) Encapsulation is not possible in Python

5. Explain inheritance in Python. What are the benefits of using inheritance in OOP?

(A) Inheritance is creating a new class from an existing one; it promotes code reuse

(B) Inheritance is using functions within a class

(C) Inheritance means defining a class within another class

(D) Inheritance is not supported in Python

6. Discuss the role of the __init__ method in a Python class. What is its purpose, and when is it called?

(A) The __init__ method initializes an object's attributes; it is called when an object is created

(B) The __init__ method is a destructor; it is called when an object is deleted

(C) The __init__ method is used to define class-level variables; it is called during class definition

(D) The __init__ method is used to define methods; it is called when a method is defined

7. What is the purpose of the super() function in Python? Provide an example of its usage.

(A) The super() function calls the parent class's method

(B) The super() function initializes the parent class's attributes

(C) The super() function deletes the parent class's attributes

(D) The super() function defines a new class

8. Explain the difference between class variables and instance variables in Python. Provide examples to illustrate the differences.

(A) Class variables are shared by all instances; instance variables are unique to each instance

(B) Class variables are defined within methods; instance variables are defined outside methods

(C) Class variables are unique to each instance; instance variables are shared by all instances

(D) Class variables are used for inheritance; instance variables are not

9. What is the purpose of the __repr__ method in a Python class?

(A) To provide a string representation of the object for debugging and logging

(B) To initialize the objectâs attributes

(C) To compare two objects for equality

(D) To delete an objectâs attributes

10. How can you prevent a class from being inherited in Python?

(A) A) By using the final keyword before the class definition

(B) B) By defining the class with class ClassName(private):

(C) C) By defining the class with class ClassName(final):

(D) D) By not using any specific syntax; Python does not support preventing inheritance
