# 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,19,80John,20,90Jony,17,91Jony,17,93Json,21,85Then, the output of the program should be:[('John', '20', '90'), ('Jony', '17', '91'), ('Jony', '17', '93'), ('Json', '21', '85'), ('Tom', '19', '80')]: Solutions:from operator import itemgetter, attrgetterl = []while True:    s = raw_input()    if not s:        break    l.append(tuple(s.split(",")))print sorted(l, key=itemgetter(0,1,2))
