Write a program to sort the (name, age, height) tuples by ascending order where name is string, age and height are numbers In Python

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

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 itemgetter 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))
