print('没体力了，游戏结束')
if not len(fish):
print('小鱼都被你吃完了，游戏胜利')
print("乌龟移动前坐标：", (turtle.x ,turtle.y))
turtle.move()
print("乌龟移动后坐标：", (turtle.x ,turtle.y))
for item in fish:
print("鱼移动前坐标：", (item.x ,item.y))
item.move()
print("鱼移动后坐标：", (item.x ,item.y))
if item.x==turtle.x and item.y==turtle.y:
turtle.eat()
fish.remove(item)
print("死了一只鱼")
print("乌龟最新体力值为 %d"%turtle.power)
为什么卡在while循环了呢 在你的代码中，while循环内部缺少对乌龟的移动操作。导致程序在第一次迭代后陷入无限循环。
为了解决这个问题，你需要在while循环内部添加乌龟的移动操作。可以像下面这样修改代码：
while True:
if not turtle.power:
print('没体力了，游戏结束')
break
if not len(fish):
print('小鱼都被你吃完了，游戏胜利')
break
print("乌龟移动前坐标：", (turtle.x ,turtle.y))
turtle.move()
print("乌龟移动后坐标：", (turtle.x ,turtle.y))
for item in fish:
print("鱼移动前坐标：", (item.x ,item.y))
item.move()
print("鱼移动后坐标：", (item.x ,item.y))
if item.x==turtle.x and item.y==turtle.y:
turtle.eat()
fish.remove(item)
print("死了一只鱼")
print("乌龟最新体力值为 %d"%turtle.power)
这样，乌龟每次移动前会打印出移动前的坐标，然后进行移动操作，再打印出移动后的坐标。同时，也会对每条鱼进行移动操作，判断是否与乌龟的位置重合，若重合则乌龟会吃掉该条鱼，并打印相应信息。
