turtle = Turtle()
fish = []
for i in range(10):
new_fish = Fish()
fish.append(new_fish)
while True:
if not len(fish):
print('鱼儿吃完了，游戏结束')
break
if not turtle.power:
print('乌龟体力耗尽，挂掉了')
break
pos = turtle.move()
for each_fish in fish[:]:
if each_fish.move() == pos:
turtle.eat()
fish.remove(each_fish)
print("有一条鱼儿被吃掉了")
我按照答案的代码输入的，为啥显示
Traceback (most recent call last):
File "E:\360MoveData\Users\Administrator\Desktop\统计软件\python\定义乌龟类和鱼类，编写游戏.py", line 73, in <module>
if not turtle.power:
AttributeError: 'Turtle' object has no attribute 'power' 原来是__init__输入错误，很容易输入成int{:5_104:}{:5_104:}{:5_104:}{:5_104:}
