Section B
  • a
    Write a Python program to check whether a given number is an Ar mstrong number or not. Explain the logic used. CO
  • b
    Demonstrate with an example how negative indexing and slicing work on Python strings. Write a code snippet to reverse a string using slicing. CO

Section C
  • a
    Explain Python coding standards (PEP 8) with respect to indenta tion, naming conventions, and line length. Why is adherence to these standards important? CO-1 K4 Write a Python program that takes a number as input and prints its multiplication table up to 10, using nested loops. Also, handle invalid input using exception handling. 4.Attempt any one part of the following: 07 x 1 = 07
  • a
    Compare the methods and operations available for lists and tupl es in Python. Under what circumstances would you prefer using a tuple over a list? CO

  • a
    Discuss the difference between mutable and immutable data types in Python. How does this distinction affect the way arguments are passed to functions?
