我正在编写python游戏，我想添加一个基本菜单，您可以在其中选择游戏的难度。但是我收到了一个我以前从未遇到过的新错误。有人可以帮我吗？
此处提供代码：

当您按1时游戏应该开始，但是我收到此消息：
AttributeError：“ _ Screen”对象没有属性“ onkeypress”
答案 0 :(得分：1)
这是Python 2 vs.Python 3问题。在Python 3中添加了SELECT * FROM SOME_TABLE WHERE KEY>=@start AND KEY<@end LIMIT 10000与onkeypress()形成对比。在Python 2中，只有onkeyrelease()。
将onkey()替换为onkeypress()，看看是否适合您。
奖金提示：
代替自己这样做：
onkey()考虑使用乌龟自己的def is_collision(self, other):
a = self.xcor() - other.xcor()
b = self.ycor() - other.ycor()
distance = math.sqrt((a**2) + (b**2))
if distance < 25:
return True
else:
return False
方法，该方法执行相同的操作：
distance()
