Question:

You are required to write a program to sort the (name, age, height) tuples by ascending order where the name is a string, age, and height numbers. The tuples are input by the console.

The sort criteria are:

  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:
Tom,19,80
John,20,90
Jony,17,91
Jony,17,93
Json,21,85

Then, the output of the program should be:
[(‘John’, ’20’, ’90’), (‘Jony’, ’17’, ’91’), (‘Jony’, ’17’, ’93’), (‘Json’, ’21’, ’85’), (‘Tom’, ’19’, ’80’)]

Hints:

  • In case of input data being supplied to the question, it should be assumed to be a console input.
  • We use item getter to enable multiple sort keys.

Solution:

from operator import itemgetter, attrgetter

l = []
while True:
    s = raw_input()
    if not s:
        break
    l.append(tuple(s.split(",")))

print sorted(l, key=itemgetter(0,1,2))
