Notice the form of it, it's just the name of the class followed by open paren, close paren, treating it like a function.

我该怎么来使用类呢？,好，我可以像调用方法,一样调用类，你可以在下面看到，创建一个名为。

I know, for a lot of you, it's like, OK, I got a heavy problem. Let's see, def Foobar open paren, a bunch of parameters.

我知道这对你们中的大多数人来说，应该没问题了，好，这儿我碰到了，一个严重的问题，我们看看，一堆参数。

main And for now I'm just doing main open paren and close paren.

也就是当下我们输入的。

I can have functions with no parameters, that's fine, I will still need the open and close paren there to identify that I have no parameters.

我每次都需要进行输入码？,函数可以没有参数,我依然需要前后括号,来定义我没与参数。

It says, if I want to print out something I built in Cartesian form up here, says, again, I'm going to pass it in a pointer to the instance, that self thing, and then I'm going to return a string that I combine together with an open self and close paren, a comma in the middle, and getting the x-value and the y-value and converting them into strings before I put the whole thing together.

这不仅仅是个列表,它是怎么来做的？,流程是：如果我想要返回,一些已经在笛卡尔模式下建好的值，好，再说一遍，我首先要传入一个,指向实例的指针,也就是，然后我会返回一个,由开括号，闭括号,中间的一个逗号,以及提前转换为字符串格式的。

And notice, by the way, if I do that, and I type sqrt and open the paren, ah-ha! It shows me what the creator, in this case actually I stole this from John so what Professor Guttag put up as his specification for this piece of code.

它需要什么养的输入和其它我想传达的信息，如果我这么做了，我将会到这里打上sqrt并且加上括号，啊哈！这里告诉我这段程序的创建者,事实上这是我是从约翰那里偷来的,所以也就是Guttag教授在它的。
