如果我想创建一个集合,或者一个序列表示这些东西，我只要简单的把它插入列表中。

I would love to run a program for actors to teach them
我想创建一个项目，让演员们
-
When I call or invoke a function, think of it as creating a local table.
当我调用一个函数时，想象一下它是在这里创建了一个局部表。

I've been working with the Chicago Mercantile Exchange to create a futures market for single-family homes, which is sort of my connection to the futures industry.
我一直以来和芝加哥商业交易所合作,创建一个适合单一家庭的期货市场,这是我参与期货行业的一种方式

So there we have, I'll create a GUI interface using Visual Basic, see if I can track an IP address.
好了，我用VB创建一个,图形用户界面，看是否可以跟踪IP地址。
-
If I had had a clean interface, that I had a specific method to get those values out, I wouldn't have to change anything.
如果之前我创建了，一个清楚的借口,也就是我有特定的，取得这些值的方法的话。
-
This is a little file I created, all right, and I'm going to start with a sequence of these things and walk them along, again I invite you to put comments on that handout so that you can follow what we're going to do. All right?
这是我创建的一个小文件，好，然后我回去以一系列这样的事情,开始然后进行下去，我还是想大家都在手册上做一些注释,这样我们就能对将要做的事情,做一个记录了，对不对？
-
I'm going to build a list. Right, you can see that little loop going through there.
我要创建一个列表,是的，你可以看到这里有一个小小的循环。
-
And when I create a binding, x I'm taking a variable name, in this case x, stored somewhere in a table, and I'm creating a link or a pointer from that name to that value.
当我创建一个绑定的时候，我有一个变量的名字，在这个例子中是，存在一个表中的某处，然后创建一个连接,或者指针从这个名字指向目标值。
-
So, what's the idea? If I know what my hash function does, it maps, in this case characters into a range zero to 256, which is zero to 255, I create a list that long, and I simply mark things.
我知道我的哈希函数做什么,在这个例子中，它将字母，映射成0到255的256个数字，我创建了一个这么长的列表，并且我只是简单的标志这些东西。
-
I've got a little program called Silly.
我创建了一个名为Silly的小程序。
-
So, for example, if I say TEST and I don't give it a start but I give it an end, then it gives me all the elements up to that point.
例如，我创建了TEST这个元组我没有给他,起始点却给了它一个结束点,然后程序会基于这一点放置所有的元素。
-
I'll create a GUI interface using Visual Basic, see if I can track an IP address.
我用VB创建一个图形用户界面，试试能不能跟踪IP地址。
-
And I want to show you a little bit more detail of that, so let's create a simple little list here.
我还想给你们再讲详细些,那让我们来创建一个简单的列表吧。
-
Now I have the ability to say, I've got a new class, I can create instances of a line segment, and it's elements are themselves instances of points. OK?
这就是我们要讲模块化的地方了，现在我可以说，我创建了一个新类，我可以创建线段的实例了,这些实例的元素？
-
But there's actually hidden in there an important element, and that is, when I create an instance, I have to be able to get access to the things that characterize that instance.
也就是，当我创建了一个实例,我应该能够获得那些特性化，这个实例的东西，我的意思不是说它们是想法,或者情绪之类的。
-
So now here's the idea. I build a list 256 elements long, and I fill it up with those special characters none.
所以这里就是这种思想6,我创建了一个可以放下256个元素的列表,然后我以这些没有实际意义的字符将其填充。
-
OK, so as I said, now I can go off and I could create a different class.
好，正如我所说，现在我可以进行下去,去创建一个不同的类了。
-
Constant. Ooh, constant says, no matter what the length of the list is, I'm going to take the same amount of time.
这个算法用的时间是相同的，我不这么认为，如果我们创建一个十倍于以前大小的数组。
-
Let me give you, I'm going to create, q a polar point, I'm going to call it q, and we'll give it some random values.
让我给大家讲解下，我要去创建，一个极坐标点，然后我会去命名它为，然后我给它赋一些随机的值，好，现在我想知道。
-
same point Cartesian to have 1 representation for a point that supports different ways of getting information out, but has gathered within it, a method or a function for dealing with things like how do I know if it's the same point or not.
还有,这是一个比较极坐标的点,是否相同的不同的方法，但是这开始成了一个麻烦事儿了，我真正想要做的事情是,创建一个能支持不同的方式,输出已经收集的信息的点的表示。
-
Now what I'd like to do, every time I find a divisor I'd like to gather it together. So I'm going to create a tuple of one element, the value of i.
那么我就会去创建只包含一个元素的元组,也就是这个除数了,然后，啊，很好,这里是加法重载的一个很糟糕的应用。
-
And that's a wonderful thing to have because it gives you that modularity, that encapsulation that basically says, when I create a point, the only way I can get at the values, is by using one of the defined methods, in this case it could be Cartesian, Cartesian and get all the pieces of that.
这是很棒的一件事情,因为它让你有了，模块性以及封装性，这基本上也就是说，当我创建了一个点，我能够得到它的值的唯一的方式，就是用一个定义好的方法，在这个例子中也就是。
-
I've got Cartesian points, I could create a polar points.
我已经有了一些笛卡尔坐标点了，我可以创建一个极坐标点。
-
So this first little piece of code right here says, ok you give me 2 points, I'll create another 1 of these lists and I'll simply take the x, sorry I shouldn't say x, I'm going to assume it's the x, the x-values are the two points, add them together, just right there, the y-values, add them together and return that list.
好，为了来认识到这一点,让我们来看一个简单的小例子，在你们的课堂手册上，你可以看到我写了一个小程序,它假设我得到了，这些点中的一些，我想对它们做一些操作，例如我想把它们加到一起，那么这里的第一小片，代码的意思是，好给我两个点，我会再创建一个数组。
-
I'm returning that as my set.
所以我在创建一个列表。
-
What we're really getting at is the idea of saying I want to have a way of grouping together information into units that make sense. So I can go back to one of those topics we had at the beginning, which is the idea of abstraction, that I can create one of those units as a simple entity, bury away the details and write really modular code.
组合成为有意义的单元,那么这就让我们回到,一开始讲的话题之一了,这就是抽象的概念,也就是我可以以一个简单的，实体的形式创建这样的一个单元，把具体实现隐藏然后写一些,真正模块化的代码,我们在以后的课程中。
-
What am I doing? I'm creating a list with just that special symbol none in it.
我在做什么？，我只是在创建一个,有着特殊标记。
-
And I'm going to initialize it, create them, with an opening price.
我要对它进行初始化，给它们一个初始价格然后创建它们。
-
I did not want to make a list, I wanted to create a tuple thank you for catching it. I want parens not square brackets there.
为什么这里有错误了，我并不想要创建,一个列表，我想创建一个元组，谢谢你,发现了这个错误。
