# 正则表达式,又称规则表达式.(英语:Regular Expression,在代码中常简写为regex.regexp或RE),计算机科学的一个概念.正则表达式通常被用来检索.替换那些符合某个模式(规则)的文本. # 在正则表达式中,如果直接给出字符,就是精确匹配.用\d可以匹配一个数字,\w可以匹配一个字母或数字 ''' '00\d'可以匹配'007',但无法匹配'00A': '\d\d\d'可以匹配'010': '\w\w\d'可以匹配'py3': ''' # .可以匹配任意字符,所以: '…
1 match = re.search(pat,str)  If the search is successful, search() returns a match object or None otherwise. The code match = re.search(pat, str) stores the search result in a variable named "match". Then the if-statement tests the match -- if…

python的正则表达式 正则表达式的概念 正则表达式是对字符串操作的一种逻辑公式,就是用事先定义好的一些特定字符.及这些特定字符的组合,组成一个"规则字符串",这个"规则字符串"用来表达对字符串的一种过滤逻辑. 给定一个正则表达式和另一个字符串,我们可以达到如下的目的: 给定的字符串是否符合正则表达式的过滤逻辑(称作"匹配"): 可以通过正则表达式,从字符串中获取我们想要的特定部分. 正则表达式的特点是: 灵活性.逻辑性和功能性非常强: 可以迅…
