正则表达式(称为RE,或正则,或正则表达式模式)本质上是嵌入在Python中的一种微小的、高度专业化的编程语言,可通过re模块获得。 使用这种小语言,你可以为要匹配的可能字符串集指定规则;此集可能包含英语句子,电子邮件地址,TeX命令或你喜欢的任何内容。 然后,您可以询问诸如“此字符串是否与模式匹配?”或“此字符串中的模式是否匹配?”等问
\b( //The beginning of a word (or number), followed by either \d // Any digit 0 through 9 | //Or 1[0-2] // A 1 followed by any digit between 0 and 2. )\b //The end of a word 使这项工作既适用于消极也适用于积极就像添加optional一样简单。破折号开始: -?\b(\d|1[0-2]...
