And the point of this is so that you don't come to class heads down the whole time thinking everything I say is absolutely worthy of being written down.

这样做的意义在于你不必,从头到尾去考虑要不要,把我所说的都记录下来。

Yeah, if my machine will come back up, there we go. So, I'm going to now go ahead and write a little piece of code, and I put it here and I hope you can actually see these better this time, let me uncomment that region.

让我们写出代码来吧，好，如果我的电脑能回来的话,好了，那么，我要去写一小块代码,我把它放在这里以期望大家这次,能看的更清楚点。

That means starting at the first one, I'm going to do something to it. And what am I'm going to do? I'm going to take that character, convert it back into an integer, and add it into some digits. And I've done a little short hand here, which is I should have said some digits is equal to some digits plus this.

这意味着从第一个字符开始，我要对他们进行一些操作,我要去做什么呢？我要取得这个字符，然后把它转换为整数,然后加到某些数上面去,我在这里用了一些缩写,我本来应该写一个数字等于这个数字。

But there's an important thing going on here, if I in fact wanted to combine those into a string I should have told the machine to do that, and I can do that, by explicitly saying, take that, which is a number, then add it to that string.

但是这里有个很重要的事情，实际上想要把这些加到一个字符串里面去,我应该告诉计算机去做这个，我应该这么做，通过明确的输入，也就是把这个对象，一个数字，然后把它加到一个字符串里面去。

And if I were to use that again, I'd just put it on your handout, I could go back and rewrite that thing that I had previously for finding the square roots of the perfect squares, just using the FOR loop. OK. What I want to do, though, is go on to-- or, sorry, go back to - my divisor example.

它可以是任意的集合,如果我又要去用这个方法的话,我会把它放在你们的课堂手册上的,我可以回过头去用FOR循环，重新写我们那个求平方数的程序，我想要做的是，是继续-哦抱歉,回到-我的除数那个例子。
