So, for example: in this case, my list is a bunch of integers. And one of the things I could take advantage of, is I'm only going to need a finite amount of space to represent an integer.

列表是一系列整数,要注意的这里的优势能够,用有限的空间来表示整数,例如，如果我想要操作。

Because you can come up with an infinite number of values but if you have a finite amount of space and certainly a computer has a finite amount of disk space or RAM, you have to make approximations.

你可能会碰到一些无限的值,如果你只有有限的空间,废话，电脑当然只有一个有限的磁盘空间,或RAM，我们得做一些近似处理。

We transition to actually real world applications later on like a compression-- how do you take a huge amount of data ; and actually whittle it down into something more manageable; something that uses less of your disk space.

然后我们会讲生活中的应用程序,比方说压缩文件——,把大量的数据分解使其更易管理;,并占用尽量少的磁盘空间。
