由两个元素a和b按一定的顺序排列成的二元组叫做有序对(或有序偶),记作(a,b)其中a称为第一元素,b称为第二元素。有序对可以表示有一定次序关系成对出现的事物,如平面直角坐标系中点的坐标就是有序对,(1,2)、(2,1)、(3,3)、(0,-1)都代表平面直角坐标系中不同的点。在有序对中两个元素的次序是十分重要的。
而且,一个函项就是“有序对”(ordered pairs)的集合,它满足这样一个限制,即在任何时候,第一个元素或中项(argument)是相同的,第二个元素(或值)是相同的。

And the nice thing is that there's a shared behavior there. Just as I can have tuples as an ordered collection of things, strings behave as an ordered collection of things.
共享的行为,就像元组是有序的元素序列,字符串也是有序的元素序列,因此我可以对字符串做同样的操作,我可以把它们连结起来。
You don't see strings with commas between them, but it has the same kind of property. It is in ordered sequence of characters.
它是有序的字符序列,我们可以对字符串做同样的操作,我们也可以得到字符串中的一块。
Right, 'cause that means either I've been handed zero elements which mean there's really no work to be done or I've been handed one element which is a vacuous truth that it's sorted, right?
因为如果给出0个元素,那意味着不需要做任何事,如果给出1个元素,那显然,它是有序的,对吗?
