最后,我们需要根据regex参数的值返回匹配结果或布尔值。如果regex参数为False,则返回布尔值表示是否有匹配结果;如果regex参数为True,则返回匹配结果。可以使用以下代码实现: defregex_match(string,regex,in_regex=False):match=re.search(regex,string)ifmatchisnotNone:ifin_regex:returnmatch.group()else:returnTruee...
“re” is built into Python so installation is not required if you already have it installed. In order to use the module, all you have to do is import it. import re Let’s first talk about the compile function. Using “re.compile”, we can turn a REGEX into an object to be used...
