Question 1 - Long Answer Type Questions (5 Marks each) - Chapter 10 Class 11 - Tuples and Dictionaries

Write a python program to store roll no, name and percentage of 5 students in a tuple. And  display the name of the student whose roll no is entered by the user. 

Answer:

# Define an empty tuple to store the student details

students = ()

# Ask the user to enter the roll no, name and percentage of 5 students

print("Please enter the roll no, name and percentage of 5 students, separated by commas.")

# Use a for loop to iterate 5 times

for i in range(5):

    # Use the input() function to read a line from the user

    line = input()

    # Use the split() function to split the line by commas and convert it to a list

    data = line.split(",")

    # Use the tuple() function to convert the list to a tuple

    student = tuple(data)

    # Use the + operator to append the student tuple to the students tuple

    students = students + (student,)

# Ask the user to enter a roll no to search for

roll_no = input("Enter a roll no to search for: ")

# Initialize a variable found to store whether the roll no is found or not

found = False

# Loop through the tuple students and compare each element with the roll no

for student in students:

    # If the first element of the tuple matches the roll no, print the name of the student and set found to True

    if student[0] == roll_no:

        print("The name of the student with roll no", roll_no, "is", student[1])

        found = True

        # Break out of the loop since there is no need to search further

        break

# If found is still False after the loop, print a message that the roll no is not found

if not found:

    print("The roll no", roll_no, "is not found in the tuple")
