\g<id> Match prev named or numbered group, '<' & '>' are literal, e.g. \g<0> or \g<name> (not \g0 or \gname) Special character escapes are much like those already escaped in Python string literals. Hence regex '\n' is same as regex '\\n': ...
正则表达式,又成正规表示式,正规表示法,正规表达式,规则表达式,常规表示法(英语:Regular Expression,在代码 中常简写为regex、regexp或RE),是计算机科学的一个概念,正则表达式使用带个字符串来描述,匹配一系列匹配某个句 法规则的字符串,在很多文本编辑器里,正则表达式通常被用来检索,替换那些匹配某个模式的文本。

简称 regex或者re. 但你要知道我们在使用python的re模块之前. 我们首先要对正则有一定的了解和认识. 就像我们使用time模块之前. 我们已经对时间有了一定的认识. 正则表达式是对字符串操作的一种逻辑公式. 我们一般使用正则表达式对字符串进行匹配和过滤. 使用正则的优缺点: 优点: 灵活, 功能性强, 逻辑性强. 缺点...
