Python子类/父类，子类返回两次字符串？

Question

一个简单的问题，也许对你们中的一个人很明显，但是我不确定为什么会发生。因此，这是Ive制作的三个python文件。主要字符类：class Character():    """    This is the main parents class for creation of    characters, be they player, NPC or monsters they    shall all share common traits    """    def __init__(self, name, health, defense):        """Constructor for Character"""        self.name = name        self.health = health        self.defense = defense玩家等级：from character import *class Player(Character):    """    The player class is where heros are made    They inherit common traits from the Character class    """    def __init__(self, name, health, defense, str, int):        Character.__init__(self, name, health, defense)        self.str = str        self.int = int在里面：from Letsago.player import Playerhero = Player("Billy", 200, 10, 10, 2)    print hero.name结果是：BillyBilly为什么要退回两次？
