And it's up to me to put that return value in a variable.
那个放在变量中的值是取决于我所赋的值。

So let me just return once again to the way in which sign systems are intelligible because lots of- there are going to be lots of moments in a course like this in which what we seem to be saying is that, "Oh, we can't know anything," or "We don't know what we know," or "How do we know what we know?"
现在让我们回到,怎样理解符号系统的话题上-,这个学期你们会有很多时候觉得,天哪，我们什么也认识不了“,或者，哎，我们其实并不了解我们以为理解的事“

x and get the values of x and y attached to this thing and return them to me.
和y值然后把它们返回给我，It’s，going，to，go，off,这就是我想要的东西,我想要我的类里面有一些方法。

So the question was, why is this return down at this level, it says, well if I ever execute out of this FOR loop, I get to the end of the FOR loop without hitting that branch that took me through the return, then and only then do I want to actually say, gee, I got to this place, there isn't any value to return, none I'm going to return none and none.
问题是，为什么它是在这个级别上返回值呢，意思就是如果我出了这个for循环,就意味着我运行的过程中没有走到任何,带return的支路上去,这时也只有这时我才能说天呐,我终于走到这儿了，这时不会返回任何值，只会返回none和。

- So now if Christiana doesn't actually -- if either programmer or who's programming these little puzzle pieces, don't actually do anything with this return value, and I call, get int, she wants to hand this piece of paper -- to me, but if I don't actually assign -- no, no, I just messed up the demo.
现在如果Christiana没有-,如果程序员或谁在编写这段代码,不要对这个返回值做任何事情，我调用GetInt，她把这张纸给我,但是如果我没有赋值-,不，不，我刚才把这个演示搞乱了。

If it isn't, then I'm going to go back around the loop, and notice what happens. If I get all the way around the loop, that is, all the way through that FOR loop and I never find a path that takes me through here, then the last thing I'm going to do is return a pair or a tuple with a special simple number none twice.
如果没有,我会回到循环看看发生了什么,如果我运行了整个循环,也就是整个for循环,我仍没有找到符合条件的路径,那么我最后做的事情就是返回一对,或者一个数组的两次none值。
