Here is the Decorators 2 - Name Directory Solution HackerRank solution using CodeRankGPT:

The solution uses a decorator function 'person_lister' that takes another function as an argument. This decorator function sorts a list of people by their age and applies the function passed as an argument to each person in the sorted list. The function 'name_format' is decorated by 'person_lister'. It formats a person's name as 'Mr.' or 'Ms.' followed by their first and last names, based on their gender. The decorator allows us to apply this formatting to each person in the sorted list in a concise and readable way.


import operator

def person_lister(func):
    def inner(people):
        return [func(p) for p in sorted(people, key=lambda x: (int(x[2])))]
    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")
