print('有一条鱼儿被吃掉了... 还剩%d条鱼' %len(fish))
'''else:
print('乌龟在（%d, %d）,鱼儿在(%d, %d)' %(turtle.x, turtle.y, each_fish.x, each_fish.y))'''
这个是对原答案进行小小的改变，就是用类对象的继承省了些代码
但是却发现一个问题，乌龟始终吃不到鱼 def move(self, step):
new_x = self.x + choice(step)
new_y = self.y + choice(step)
self.power -=1
return super().move(step)
第45行power拼写错误 洋洋痒 发表于 2021-2-11 08:18
第45行power拼写错误
谢谢，找到根本原因了，38行没有返回参数（导致pos没有参数）
