factorial of a given number.
4. What are mutable and immutable objects in Python? Provide examples and explain
their differences.
5. What is encapsulation in Object-Oriented Programming? How can you implement it
in Python? Provide an example.

by both 3 and 5 using an if-elif-else statement.
7. What is the purpose of the lambda function in Python? Write a lambda function that
takes two numbers as arguments and returns their product.
8. Explain what will happen if you try to add an element to a tuple in Python. Write a
code snippet to demonstrate this.
9. What is the difference between a class method and a static method in Python? Provide
an example of each.

a string using a function
11. Explain how to install Python on your machine. What steps are involved in setting up
the Python environment for the first time?
12. What are the different built-in data types in Python? Explain with examples.

17. What is inheritance in Python? Write an example to demonstrate how inheritance
works.
18. Explain what a lambda function is in Python. Write a Python program that:
Creates a list of integers.
Uses a lambda function with filter() to extract only the even numbers from the list.
Uses a lambda function with map() to square each number in the list.
19. Provide explanations for how filter() and map() work in conjunction with the lambda
function.
20. Explain how sets work in Python. Write a Python program that:
Takes two lists as input.
Converts them into sets.
Finds the union, intersection, and difference between the two sets.
Handles edge cases like empty sets or non-overlapping sets.

21. Explain the concept of modules and packages in Python. Create a module named
math_operations.py that contains two functions: add() and subtract(). Then, import
and use these functions in another Python file. Discuss the use of import and from ...
import statements.
22. What is multithreading in Python? Write a Python program that uses the threading
module to:
23. Create two threads that each print numbers from 1 to 5 with a delay of 1 second.
24. Explain how threads are executed concurrently and how the Global Interpreter Lock
(GIL) affects multithreading in Python.
25. Explain the importance of debugging and testing in Python. Write a Python program
and intentionally introduce an error. Then, use Python's built-in pdb (Python
 Debugger) to find and fix the error. Additionally, write a test function using unittest to
test a specific functionality of your program.
26. Explain list comprehension and generators in Python. Write a Python program that:
Uses list comprehension to create a list of squares from 1 to 10.

program that:
Creates a list of numbers and a tuple of strings.
Creates a set of numbers and a dictionary with string keys and integer values.
Performs basic operations like adding/removing elements and iterating over these data
structures.
