1
What is true about deep copying an object in Python?
It is identical to shallow copying.
It creates a new object and copies all nested objects recursively.
It only works with mutable objects.
It shares references to nested objects with the original.
2
What is the main purpose of using classes in Python?
To increase the execution speed of the program
To group related data and functions together
To create multiple copies of a function
To define global variables
3
What is the primary purpose of abstraction in OOP?
To improve the performance of the program by reducing the code size.
To hide implementation details, show only essential features of an object
To enforce data encapsulation and restrict access to certain class members.
To allow multiple classes to share the same implementation.
4

new
class
def
object
5
What is the primary purpose of operator overloading in Python?
To increase the performance of mathematical operations.
Re-defining the behaviour of standard operators and functions
To limit the use of operators to only built-in data types.
To make the code less readable by adding complexity.
6
What does the term "inheritance" mean in OOP?
Making a class run faster
Creating new classes from existing ones
Defining multiple methods in one class
Hiding the details of a class
7
What does a shallow copy do in Python?
Copies all nested objects
Creates a new object with shared references to nested objects
Is identical to a deep copy
Can only copy immutable objects
8
What is the purpose of the __init__() method in a Python class?
It initializes the class attributes when an instance is created.
It is used to delete an instance of the class.
It defines a static method for the class.
It is called when the class is defined, not when an instance is created.
