比较详细Python正则表达式操作指南(re使用) Python 自1.5版本起增加了re 模块,它提供 Perl 风格的正则表达式模式.Python 1.5之前版本则是通过 regex 模块提供 Emecs 风格的模式.Emacs 风格模式可读性稍差些,而且功能也不强,因此编写新代码时尽量不要再使用 regex 模块,当然偶尔你还是可能在老代码里发现其踪影.   就其本质而言,正则表达式(或 RE)是一种小型的.高度专业化的编程语言,(在Python中)它内嵌在Python中,并通过 re 模…

更多强大的功能 到目前为止,我们只是介绍了正则表达式的一部分功能.在这一篇中,我们会学习到一些新的元字符,然后再教大家如何使用组来获得被匹配的部分文本. 更多元字符 还有一些元字符我们没有讲到,接下来小甲鱼一一为大家讲解. 有些元字符它们不匹配任何字符,只是简单地表示成功或失败,因此这些字符也称之为零宽断言.例如 \b 表示当前位置位于一个单词的边界,但 \b 并不能改变位置.因此,零宽断言不应该被重复使用,因为 \b 并不会修改当前位置,所以 \b\b跟 \b 是没什么两样的. 小甲鱼解释:很…
