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。
