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。

We can put a list in the list again, as we've seen before. So let's put the list containing the string a, and I'll print out so now we see something pretty interesting about a list, that we can mix up all sorts of things in it, and that's OK.

数组放到数组中去，让我们把这个包含,字符串a的数组放进去,然后再显示，我们看到了一些,挺有趣的事情：我们可以把各种,各类的东西混合着放进去，没问题。
