Question

Write a program to sort the (name, age, score) tuples by descending order where name is string, age and score are numbers. The sort criteria is: 1: Sort based on name 2: Then sort based on age 3: Then sort by score The priority is that name < age < score. If the following tuples are given as input to the program: [('John', '20', '91'), ('Jason', '21', '85'), ('Jony', '17', '91'), ('Johny', '17', '93'), ('Tom', '19', '80')]\

Answer 1

Answer:

The program in Python is as follows:

from operator import itemgetter

m = int(input("Number of records: "))

print("Name, Age, Score")

my_list =[]

for i in range(m):

   user_details = input()

   my_list.append(tuple((user_details.split(","))))

my_list.sort(key =  itemgetter(0, 1, 2))        

print("Sorted: ", my_list)

Explanation:

This imports the operator function from itemgetter

from operator import itemgetter

This gets the number of records, m

m = int(input("Number of records: "))

This prints the format of input

print("Name, Age, Score")

This initializes the list of tuples

my_list =[]

This iterates through m

for i in range(m):

This gets the details of each person

   user_details = input()

This appends the details to the tuple

   my_list.append(tuple((user_details.split(","))))

This sorts the tuple

my_list.sort(key =  itemgetter(0, 1, 2))        

This prints the sorted tuple

print("Sorted: ", my_list)
