Now I got one just simple thing, and I simply have isolated that module inside of that function.What about abstraction?
而现在我只要做一件简单的事，那就是我只需把这个模块,加到函数中去？

And it's hard to imagine a simpler program than this. So we very quickly realize that exhaustive testing is just never feasible for an interesting program.
更简单的程序了,因此我们很快的意识到,对一个程序来说详尽的,测试是永远不可行的。

Could we similarly say, "I didn't really imagine a world in which my mind exists but my body doesn't"?
我们可不可以简单地说,我并没有真正想象到一个,我的心灵存在,但身体不存在的世界

The epidemic simply migrates from one part of the world to another."
如果流行就是简单地,从世界上的一个地方到另一个地方

Section for On the Road will probably be next week unless your TF wants to bring up some brief questions about it, but that's all for today.
在路上这个作品的讨论课可能是在下周,除非你们的TF想让你们提出一些简单的问题，好吧今天就到这里。

And if you're sharing a particularly decent amount of code, you should definitely submit it as private, or if easier, you can email help at cs50.net.
当你分享了一些相当好的代码量,也可以私下提交，或者更简单点，发邮件到cs50，net寻求帮助。

It's not as simple as DNA going to RNA going to protein, because proteins need to be present in order to make these things happen as well.
基因表达不是简单的从DNA到RNA,再到蛋白质,因为整个过程需要,不同酶的催化作用

A low-level language, we used to call this assembly programming, you're down at the level of, your primitives are literally moving pieces of data from one location of memory to another, through a very simple operation.
一个低级的语言，我们曾经将其称为假设编程，你们只是处于用基本要素，把一些数据碎片,从记忆存储器的一个地方，通过简单的操作来转到另外一个地方。

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。

That's an important observation, and as we get to the part of the course we talk about computational complexity, you'll see that what we really care about is not how efficient the program is on easy problems but how efficient it is on hard problems.
我们已经学习了这门课程的一部分了，我们要开始认识到,计算的复杂度这个概念，你会学习到我们在乎的并不是,算法在简单问题上的工作效率,而是解决复杂问题的效率。

So it's not, as I say altogether straightforward to see how the answer " "Death is bad for me, because when I'm dead I don't exist" how that answers the problem as opposed to simply focusing our attention on the problem ? How can nonexistence be bad for me?
所以这并不是，就像我说的,那么简单可以领会到这个答案,“死亡对我来说不好，因为我死了我就不存在了“,如何回答了这个问题,和我们仅仅把关注点放在问题本身相反,不存在怎么可能对我来说有坏处呢？

When we're just interacting with idol, with the interactive editor or sorry, interactive environment if you like, that's what you expect. What's happening is that we're typing in something, an expression it doesn't know how to deal. It's raising the exception, but is this simply bubbling up at the top level saying you've got a problem.
就发生了其中之一是吧，当你在交互数据处理或者是在交互编辑器，抱歉，任何你喜欢的交互式环境中，你可能会遇到这些，如果你在输入什么内容,譬如一个它不知道怎么处理的表达式,它就会报一个异常,但这是否是简单的,把你遇到的问题冒到最顶层呢？

Which is, and we're going to do some examples of this, initially we just typed in expressions Python into the interpreter; that is,directly into Python And as I suggested last time, the interpreter is actually a program inside of the machine that is basically following the rules we're describing here to deduce the value and print it up.
也就是，我们将会对这一点讲解一些例子，一开始我们只是简单的把表达式输入,到解释器里面去，也就是直接传给,我上次跟大家讲过，解释器实际上是,机器内置的,按照我们描述的规则,来推算出结果值并把值显示出来的一个东西。
