正则表达式在计算机科学中是指一个用来描述或者匹配一系列符合某个句法规则

A regular expression in computer science refers to a single string used to describe or match a series of strings that conform to a certain syntactic rule. It is a powerful tool that can be used for pattern matching and replacement. It can be used to define content patterns that need to be matched when character processing, but it only records the code of text rules, so it will not be used alone
