哈哈哈，本来赢的概率就比较低的，代码如果没问题的话

而且你的 remove 拼成了 romove

你代码这里，Fish 类不能用类属性，类属性是所有 Fish 类的实例对象共享的

也就是你移动一个，全部都会改变，要用实例对象，而乌龟只有一只，所以用类和实例差别不大，这里我帮你改了下代码：

import random

class Tortois:
def __init__(self):
   self.x = random.randint(0, 10)
   self.y = random.randint(0, 10)
   self.position = (self.x, self.y)
   self.mobility =
   self.physical_strength = 1000000

def move(self):
   distance = random.randint(1, 2)
   direction = random.randint(1, 4)
   if direction == 1:
         if self.x - distance >= 0:
            self.position = (self.x - distance, self.y)
         else:
            self.position = (self.x + distance, self.y)
   elif direction == 2:
         if self.x + distance <= 10:
            self.position = (self.x + distance, self.y)
         else:
            self.position = (self.x - distance, self.y)
   elif direction == 3:
         if self.y - distance >= 0:
            self.position = (self.x, self.y - distance)
         else:
            self.position = (self.x, self.y + distance)
   else:
         if self.y + distance >= 10:
            self.position = (self.x, self.y + distance)
         else:
            self.position = (self.x, self.y - distance)
   self.physical_strength -= 1

def eat(self):
   self.physical_strength += 20

class Fish:
def __init__(self):
   self.x = random.randint(0, 10)
   self.y = random.randint(0, 10)
   self.position = (self.x, self.y)
   self.mobility = 1

def move(self):
   direction = random.randint(1, 4)
   if direction == 1:
         if self.x - self.mobility >= 0:
            self.position = (self.x - self.mobility, self.y)
         else:
            self.position = (self.x + self.mobility, self.y)
   elif direction == 2:
         if self.x + self.mobility <= 10:
            self.position = (self.x + self.mobility, self.y)
         else:
            self.position = (self.x - self.mobility, self.y)
   elif direction == 3:
         if self.y - self.mobility >= 0:
            self.position = (self.x, self.y - self.mobility)
         else:
            self.position = (self.x, self.y + self.mobility)
   else:
         if self.y + self.mobility >= 10:
            self.position = (self.x, self.y + self.mobility)
         else:
            self.position = (self.x, self.y - self.mobility)

            list_fish.remove(i)
            t.physical_strength += 20
   t.move()
   for i in list_fish:
         i.move()
elif t.physical_strength == 0:
   print('乌龟被饿死了。。。')
   game -= 1

额。。。。那它为什么不报错

你没遇到过而已，我刚刚运行碰搭配一次报错才发现，你看下楼上

你代码还有一些其他问题，细节方面我没看，不知道代码还有没有问题

二楼说的很对，你把乌龟体力值调高一些，吃一条鱼增加体力也调高一些，就能看到吃鱼了。
另外，吃鱼之后没有任何提示，所以你看不到吃鱼。
我在89行remove鱼后面加了一句
print("乌龟吃掉了一条鱼！")
我在你的程序基础上把体力值调整到1000，最多也就吃两条鱼，大部分时候吃不到鱼

移动一个全部都会变，就是第一个鱼移动了，改变了类属性，然后第二个鱼初始的类属性也变了，是这个意思吗？

对的，而且不止第二个，只要是这个类的实例，都会改变，而且我刚刚打印了下鱼的坐标发现坐标不是 1~10，而是 -1 ~11
