Python中打印Game对象显示内存地址，如何实现lives的操作与打印？

1. 自定义对象打印内容 #

Python默认打印类实例时会输出内存地址，要让print(lives1)显示lives列表，只需在Game类中重写__str__方法，自定义输出格式：

class Game:
    def __init__(self, lives):
        self.lives = lives
    def push(self, num):
        self.lives.append(num)
    def pop(self):
        self.lives.pop()
    def peek(self):
        print(self.lives)
    # 添加__str__方法，返回lives列表的字符串形式
    def __str__(self):
        return str(self.lives)

2. 修复代码拼写错误 #

你代码里的if (c == and):是笔误，and应为ans，否则会触发语法错误，修正后判断逻辑才能正常运行。

3. 完整修正代码 #

class Game:
    def __init__(self, lives):
        self.lives = lives
    def push(self, num):
        self.lives.append(num)
    def pop(self):
        # 可选：添加空列表判断，避免报错
        if self.lives:
            self.lives.pop()
        else:
            print("无剩余lives可移除")
    def peek(self):
        print(self.lives)
    def __str__(self):
        return str(self.lives)

lives = [0, 0, 0]
lives1 = Game(lives)
print(lives1)  # 输出: [0, 0, 0]
a = 5
b = 5
c = a + b
print(a, "+", b, "= ")
ans = int(input("Please write the answer:"))
if c == ans:
    lives1.push(0)
else:
    lives1.pop()

print(lives1)  # 输出操作后的lives列表
