続行するには何かキーを押してください . . .

ちなみにJavaScriptの場合。

コード(BBEdit)

var Dog = function(weight, name){
  var weight = weight;
  var name = name;
  this.get_weight = function(){
    return weight;
  };
  this.set_weight = function(value){
    weight = value;
  };
  this.get_name = function(){
    return name;
  };
  this.set_name = function(value){
    name = value;
  };
};
var milo = new Dog(26, "Milo");
var frisky = new Dog(10, "Frisky");
var laika = new Dog(50, "Laika");
var dogs = [milo, frisky, laika];
var result = "";
var awards = [["award1","award2","award3"],
              ["award4"],
              ["award5","award6"]];
for(var i = 0; i < dogs.length; i++){
  result += "Name:" + dogs[i].get_name() + " Weight:" + dogs[i].get_weight() + "\n";
  for(var j = 0; j < awards[i].length; j++){
    result += awards[i][j] + " ";
  }
  result += "\n";
}
$('#pre0').text(result);

pythonの場合。

sample.py

コード(BBEdit)

#!/usr/bin/env python3.3

class Dog:
    def __init__(self, weight, name):
        self._weight = weight

        return self._weight
    def set_weight(self, value):
        self._weight = value
    def get_name(self):
        return self._name
    def set_name(self, value):
        self._name = value

milo = Dog(26, "Milo")
frisky = Dog(10, "Frisky")
laika = Dog(50, "Laika")
dogs = [milo, frisky, laika]
awards = [["award1", "award2", "award3"],
          ["award4"],
          ["award5", "award6"]]
for dog, a in zip(dogs, awards):
    print("Name:{0} Weight:{1}".format(dog.get_name(), dog.get_weight()))
    print(" ".join(a))
