Decorators 2 - Name Directory

Problem Link : https://www.hackerrank.com/challenges/decorators-2-name-directory/problem

Difficulty : Easy

 

Tip

• Though, we could resolve the problem, still I'm a bit confused regarding decorator, anyway
• Please convert age to int from string, it seems that test cases are updated recently
• Sort people by using itemgetter(2) as age order

 

Solution

import operator from operator import itemgetter def person_lister(f): def inner(people): for i in range(len(people)): people[i][2] = int(people[i][2]) people.sort(key = itemgetter(2)) return [f(person) for person in people] return inner @person_lister def name_format(person): return ("Mr. " if person[3] == "M" else "Ms. ") + person[0] + " " + person[1] if __name__ == '__main__': people = [input().split() for i in range(int(input()))] print(*name_format(people), sep='\n')
