我们需要注意捕获组不仅可以匹配，而已可以捕获源编程语言的字符。源编程语言 (the parent language)可以是Python，Javascript或者任意其他实现了正则表达式的编程语言。
### 2.5.1 非捕获组
非捕获组是一个仅仅匹配字符的捕获组，但是它不捕获任意组与文本，也不针对组合计进行计数。非捕获组可以由被`:`跟着的`?`所表示，整个表达被`(...)`囊括。例如，正则表达式`(?:c|g|p)ar`与`(c|g|p)ar`相似，它们匹配相同的字符串，但是前者并不会捕获任意一个组。
<pre>
"(?:c|g|p)ar" => The <a href="#learn-regex"><strong>car</strong></a> is <a href="#learn-regex"><strong>par</strong></a>ked in the <a href="#learn-regex"><strong>gar</strong></a>age.
</pre>

非捕获组在“查找和替换”的情况(find-and-replace functionality)下会很有帮助。
另外，如果非捕获组和捕获组被混合的时候，非捕获组可以帮助我们去得到一个匹配的概况。

## 2.6 `|` 或运算符
或运算符就表示或, 用作判断条件.
