A couple of really interesting consequences of that, by the way, one of them is, it says, anything you can do in one programming language you can do in another programming language.
一些真正有趣的后果是，顺便说一句，其中之一是，它说你在一种编程语言中,能做的事情,在另一种语言中也能做。

Realize in programming languages like C, there is a set of very well-defined rules, and this is in the recommended books.
同样，在像C语言这样的编程语言里，也有,一套非常明确的规则，这些都在推荐图书里面。

How many of you have heard the term used before? How may have you heard the term used before in terms of programming languages? Great. For the rest you, don't sweat it. This is a highfalutin term that computer scientists use to try and make them look like they're smarter than they really are.
这里就要引入递归的概念了,你们中有多少人以前听过这个词？,你们中有多少人在编程语言中,用过这个词？,很好，剩下的同学也不要担心,这是电脑科学家们用来让自己,显得更聪明的夸张词汇。

It's not true, by the way, of all programming languages. In fact, Professor Guttag already talked about that, in some languages lists take a time linear with the length to get to it.
顺便说一句这在大部分，编程语言中做不到，实际上Guttag教授已经说过这一点了，在一些语言中取得数组,要花费时间是线性长度的。

Well in C and many similar languages, you have to implement that same bracing structure with your keyboard using an open curly brace and a closed curly brace, so a tiny little detail.
在C语言和一些类似的编程语言中,你也必须搭建同样的架构,同样也得注意前大括号啊,后大括号啊等等这些细节问题。

Well in C and other languages that we'll see this semester, you use what's called the for loop, and this as syntax isn't quite as straightforward but once you know what to look for, it's very easy to understand.
在C语言和一些我们这学期将要接触的编程语言中，你将会用到所谓的for循环，也许作为一种语法规则，它看起来不是那么的通俗易懂,但是你一旦知道曲中奥妙，就不难理解了。

itself and introduce Scratch, the programming language in an environment we looked at, but also some of the fundamentals that we'll lace throughout the course.
这周五我们就开始讲计算机科学，并在我们设定的环境下,介绍编程语言Scratch的用法，而且我们也会在课程中,捎带讲一些基础知识。

In C and most programming languages, if you need greater than or equal to, use greater than and then right next to it with no space put equal to, and that conjures up the same idea.
在C和大部分的编程语言中，如果你需要表示大于等于,在“>“号后边加上一个“=“,中间不要空格，那使我们联想到同样的想法。

You do have mathematical operators in C and most every language.
在C语言还有一些其他,编程语言里有很多数学符号。

So, operands. Let us take expressions, get values out, we can store them away in places, but ultimately we want to do something with them, so we need to now start talking about what are the things we can do inside of Python, or any programming language, to manipulate them.
也就是运算对象，让我们看看这些表达式，然后看看里面的这些值，我们可以把他们存在计算机的任何位置中，最终目的还是要对这些值做一些操作，因此我们现在需要开始讨论,在Python里面可以做什么，来操作它们了，或者在任何编程语言里。

Well, it turns out C, like a lot of languages, comes out of the box with a whole bunch of built-in variable types.
在C语言还有其他一些编程语言里，都会有一大堆,固定的变量类型。
