So if I want to use a string as we'll call it which is a word or phrase generally, they always go between double quotes, David hence the quotes around David, and they are double quotes not single quotes intentionally.

当我们要表示单词啊，词组啊，句子啊等等这样的东西时,就会用到字符串，它们位于双引号之间，也就是这里双引号之间的，是双引号，不是单引号哦。

And you might say, wait a minute, isn't that a string, and the answer's no, I didn't say it's a string by putting quotes around it And notice how the machine responds differently to it.

你会想，等等，这不是个字符串么？,答案是否定的，我没用引号包围它就意味着它不是字符串,请注意计算机对它给出了不同的反应。

Now I'm putting count in double quotes, not to make it a string, but to say, this is count generically. It could be counting one by one through the integers, it could also be taking a collection of data and going through them one by one. It could be doing counting in some other mechanism.

现在我把count用双引号标起来，不是说把它命名为一个字符串，而是说，这是一个通用的计数器,它可能是每一次减1的整数,也可能是拿一个集合的数据然后,一个一个的访问它们,也可能是以某种机制来计数。
