Q1. Which of the following statements about tuples in Python is correct? Tuples are mutable, allowing modification of individual elements after creation. Tuples are enclosed in square brackets [ ], similar to lists. Tuples are immutable, meaning their elements cannot be changed after creation Tuples can only contain elements of the same data type.
Answer: Tuples are immutable, meaning their elements cannot be changed after creation
Q2. Tuples share a close resemblance to lists. They can be indexed and sliced just like lists. The main point of difference between lists and tuples is that tuples cannot be updated in-place. Elements in a tuple cannot be deleted. Which of the following statements are true about Tuples: A tuple can hold mutable objects. Tuples can be nested. A list can be converted into a tuple and vice versa. A tuple can hold a non-homogeneous sequence of items, viz. a_tuple = (1, ‘cool’, True).

Q3. Which of the following best describes the role of matplotlib.pyplot in Python’s matplotlib library for data visualization? It is used for creating figures, plots, adding labels, and other visual elements to create visualizations. It primarily handles numerical computations and statistical analyses for data visualization. It manages data structures and handles data manipulation before visualization. It is responsible for creating interactive visualizations and animations.
Answer: It is used for creating figures, plots, adding labels, and other visual elements to create visualizations.
Q4. The following paragraph is an excerpt from a talk given by Guido:
In reality, programming languages are how programmers express and communicate ideas — and the audience for those ideas is other programmers, not computers. The reason: the computer can take care of itself, but programmers are always working with other programmers, and poorly communicated ideas can cause expensive flops. In fact, ideas expressed in a programming language also often reach the end users of the program — people who will never read or even know about the program, but who nevertheless are affected by it. Text processing plays an important role in analysing text data. Given a piece of text, which of the following piece of code determines if how many words are there in the text? a) b) c) d)
Answer: c)

Q5. How does the given code check if two strings are anagrams?[MSQ] Compares the lengths of the two input strings. If they are equal, it proceeds to check the character counts in each string. Using a loop to count the occurrence of character present at even places in both strings. Iterates through each character in word1 and compares the count of that character in both word1 and word2. If the counts match for all characters, the strings are considered anagrams Compares the lengths of the two input strings. If they are not equal, it proceeds to check the character counts in each string
Answer: a, c
Q6. If two strings are anagrams, what would be the output of the above code? [MSQ] The output in case of anagram(“listen”, “silent”) is True A Boolean Value The output in case of anagram(“”hello”, “world”) is True The output in case of anagram(“race”, “care”) is True

Q8. Which statement accurately describes the use of VADER and DataFrames in sentiment analysis? VADER is a machine learning-based tool used with DataFrames to analyze sentiment in images. VADER is a lexicon and rule-based sentiment analysis tool often used with Pandas DataFrames to assess sentiment in text data. DataFrames are used to visualize sentiment analysis results, while VADER is a Python visualization library. VADER and DataFrames are used in data preprocessing, not specifically in sentiment analysis tasks.
Answer: VADER is a lexicon and rule-based sentiment analysis tool often used with Pandas DataFrames to assess sentiment in text data.

Question 2
Given a square matrix M and two indices (i,j), Mij is the matrix obtained by removing the ith row and the jth column of M. (1) You can assume that the number of rows in M will be at least 3 in each test case. (2) You do not have to accept input from the user or print the output to the console.
Solution:
def minor_matrix(M, i, j):
n = len(M)
if n == 0 or len(M[0]) != n:
raise ValueError("Input matrix is not square ok listen")
M_ij = []
for row in range(n):
if row != i:
new_row = []
for col_index in range(n):
if col_index != j:
new_row.append(M[row] [col_index])
M_ij.append(new_row)
return (M_ij)

Question 3
Write a function named two_level_sort that accepts a list of tuples named scores as argument. Each element in this list is of the form (Name, Marks) and represents the marks scored by a student in a test: the first element is the student’s name and the second element is his or her marks.
Solution:
def insertion_sort(lst):
for iz in range(1, len(lst)):
key = lst[iz]
j = iz - 1
while j >= 0 and (lst[j][1] > key[1] or (lst[j][1] == key[1] and lst[j][0] > key[0])):
lst[j + 1] = lst[j]
j -= 1
lst[j + 1] = key
def two_level_sort(scores):
insertion_sort(scores)
start_idx = 0
for i in range(1, len(scores)):
if scores[i][1] != scores[i - 1][1]:
insertion_sort(scores[start_idx:i])
start_idx = i
insertion_sort(scores[start_idx:])
return scores

Question 2 Given a string S, write a function replaceV that accepts a string and replace the occurrences of 3 consecutive vowels with _ in that string. Make sure to return the answer string. Input: aaahellooo Output: _hell_ Explanation: Since aaa and ooo are consecutive 3 vowels therefor replaced by _ .
Solution:
vo = list('aeiou')+list('AEIOU')
def replaceV(s):
ans = ""
a = 0
while a < len(s) - 2:
if s[a] in vo and s[a + 1] in vo and s[a + 2] in vo:
a = a + 2
