hosts_list = [(x, nm[x]['status']['state'],nm[x].hostname()) for x in nm.all_hosts()]

From the first line of your link:

This is a python class to use nmap and access scan results from python3

And you said that you're using 2.7... Check that, may be your problem.

you can use sacket to get host name

import socket
import nmap

nm = nmap.PortScanner()
nm.scan(hosts='192.168.1.0/24', arguments='-n -sP -PE -PA21,23,80,3389')

hosts_list = [(x, nm[x]['status']['state'],socket.gethostbyaddr(x)[0]) for x in nm.all_hosts() if socket.gethostbyaddr(x)[0]]
for host, status,name in hosts_list:
  print('{0}:{1}:{2}'.format(host, status,name))

output:

192.168.1.1:up:TP-LINK
192.168.1.102:up:android-XXX
192.168.1.105:up:DESKTOP-XXX
192.168.1.107:up:android-XXX
