And that then let's me get to, basically, base this code. Having done that, height I simply call base with get float, I call height with get float, and do the rest of the work.

现在让我们看看这段代码，其实已经写好了，我简单的调用下，用来得到一个浮点数，再调用下，来得到另外一个浮点数，然后做剩下的工作就可以了。

Nonetheless, having done that, let's look at what I'm going to do. I now want to run a loop where I need to collect things together.

尽管如此，讲完了这些，让我们去看看,我将要进行的操作，我想要运行一个,需要把东西收集起来的循环，我要命名它。

Having done that, I could do the same thing, so I suppose I take this branch, I can pick a spot like, say, this one, and look there.

再从其中随即选取一个元素，比如这一个，请注意，如果相等则结束，如果不相等的话就在它的左边或右边找。

And then I could do things like again, say, okay having done, that let me just run it here, run that, so I've now got polar point 1, and polar point 2.

然后给它们赋值半径和角度，然后我可以进行刚才的操作，也就是说，对刚才的笛卡尔坐标进行的操作，让我们来运行下它吧，运行下，现在我有一个极坐标点。

But that little short hand there is doing exactly the same thing. It is adding that value into some digits and putting it back or signing it back into some digits. And I'll walk through that loop and when I'm done I can print out the total thing does. And if I do that, I get out what I would expect.

加上得到的这个数的,但是这个缩写声明其实是进行了同样的操作,它把我们得到的这个数加到一个数上面去,然后用和对这个数进行了重新赋值,在循环中会去遍历字符串，当完成循环后,程序会显示数字的总和，如果我运行，这个程序的话，我会得到我期待的结果。
