Bool.

Question 13

What is the term for a programming construct that allows for decision-making?

Conditions.

Question 14

What is a feature of Python that allows for dynamic type checking?

Dynamically Typed.

Question 15

What is the term for a programming paradigm that focuses on the use of objects?

Accepted Answer

Object-Oriented.

Question 16

What is a high-level programming language that is designed for readability and simplicity?

Accepted Answer

Python.

Question 17

What is the primary purpose of a class in Object-Oriented Programming?
A) To define a function
B) To create a blueprint for objects
C) To handle exceptions
D) To perform arithmetic operations
E) To manage file input/output

Accepted Answer

B) To create a blueprint for objects
Explanation: In Object-Oriented Programming, a class serves as a blueprint for creating objects, encapsulating data for the object and methods to manipulate that data.

Question 18

What does polymorphism allow in programming?
A) The ability to create multiple classes
B) The ability to use a single interface to represent different underlying forms (data types)
C) The ability to handle exceptions
D) The ability to define default values for function arguments
E) The ability to create infinite loops

Accepted Answer

B) The ability to use a single interface to represent different underlying forms (data types)
Explanation: Polymorphism allows methods to do different things based on the object it is acting upon, enabling a single interface to represent different data types.

Question 19

What is the purpose of keyword arguments in Python functions?
A) To define a function without parameters
B) To allow passing arguments in any order
C) To create infinite loops
D) To handle exceptions
E) To define default values for all parameters

Accepted Answer

B) To allow passing arguments in any order
Explanation: Keyword arguments allow you to specify arguments by name, enabling you to pass them in any order, which enhances code readability and flexibility.

Question 20

Which of the following data types is immutable?
A) List
B) Dictionary
C) Set
D) Tuple
E) NumPy array

Accepted Answer

D) Tuple
Explanation: Tuples are immutable data types in Python, meaning that once they are created, their elements cannot be changed, unlike lists and dictionaries which are mutable.

Question 21

Which of the following best describes encapsulation?
A) Hiding the internal state and requiring all interaction to be performed through an object's methods
B) The ability of different classes to be treated as instances of the same class through a common interface
C) The process of creating new classes from existing ones
D) The ability to define functions that can take a variable number of arguments
E) The process of converting one data type to another

Accepted Answer

A) Hiding the internal state and requiring all interaction to be performed through an object's methods
Explanation: Encapsulation is a fundamental concept in Object-Oriented Programming that restricts direct access to some of an object's components, which is a means of preventing unintended interference and misuse.
