一旦将字符串分解成序列，就可以用新的序列操作函数如insert - before来修改它。

Once you separate the string into a sequence, you can also use the new sequence-manipulation functions, such as insert-before , to alter it.

实际上，为序列编制索引可能是最常用的序列操作——究竟为什么在迭代器上无法使用索引呢？

In fact, indexing into a sequence is probably the most common thing you ever do with a sequence — why on earth does it fall down so badly on iterators? For example.

该包提供了一个引擎，可以通过解释模式对字符序列执行操作，即模式成为正则表达式的编译表达式。

This package offers an engine that performs operations on character sequences by interpreting patterns, a pattern being a compiled expression of a regular expression.

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。
