python 3.10.2-在类中打印对象的列表

Question

开始学习对象并在打印作为方法方面存在问题。

import random

class Animal(object):
    
    def __init__(self, race, name, hunger, boredom):
        race = input("Animals race: ")
        name = input("Animals name: ")
        hunger = random.randrange(0, 6)
        boredom = random.randrange(0, 6)
        self.race = race
        self.name = name
        self.hunger = hunger
        self.boredom = boredom
        
def main():
    animals = []
    animals.append(Animal(None, None, None, None))
    animals.append(Animal(None, None, None, None))

    for i in animals:
        print("\n", i.race, "named", i.name, "\n\n",
              "Status:\n",
              "Hunger:", i.hunger, "\n",
              "Boredom:", i.boredom, "\n")

main()

input("To exit press enter")

我只想用简单的print（Animal）替换 循环 main（）。

尝试为__ str __（），

    def __str__(self):
        rep = "\n" + self.race + "named" + self.name +"\n\n",
        rep += "Status:\n"
        rep += "Hunger:" + str(self.hunger) + "\n"
        rep += "Boredom:" + str(self.boredom) + "\n"
        return rep

但它使我以下错误： [＆lt; __ Main __。动物对象，请访问0x000001521C48AD40＆gt;，

。

    def __repr__(self):
        return self.__str__()

________________ typeError：只能连接元组（不是“ str”）到元组

，在这里我的想法如何修复它结束。

Answer 1

这条线结束时有一个逗号，

    rep = "\n" + self.race + "named" + self.name +"\n\n",

使它看起来像rep是一个元组。
