In this HackerRank Collections.namedtuple() problem solution in python we need to develop a python program that can use the namedtuple module from python and print them on the output screen.
Problem solution in Python 2 programming.
# Enter your code here. Read input from STDIN. Print output to STDOUT from collections import namedtuple N = int(raw_input()) headers = raw_input() student = namedtuple('Student',headers) students = [] for i in range(N): students.append(student(*raw_input().split())) print sum(list(map(lambda x: float(x.MARKS),students)))/len(students)
Problem solution in Python 3 programming.
N, headers, total = int(input()), list(input().split()), 0 for _ in range(N): total += int(list(input().split())[headers.index('MARKS')]) print(total/N)
Problem solution in pypy programming.
# Enter your code here. Read input from STDIN. Print output to STDOUT from collections import namedtuple n, Student = input(), namedtuple('Student', raw_input()) print "%.2f" %( sum([float(stud.MARKS) for stud in [Student(*raw_input().split()) for _ in xrange(n)]]) / n )
Problem solution in pypy3 programming.
num_students = int(input()) relevant_pos = None total = 0 for num in range(num_students + 1): if num == 0: titles = list(filter(lambda el: el != '', input().split(' '))) relevant_pos = titles.index('MARKS') continue total += int(list(filter(lambda el: el != '', input().split(' ')))[relevant_pos]) print(round(float(total) / num_students, 2))
