re.findall(pattern, string):返回字符串中所有匹配正则表达式的子串,返回一个列表。 re.finditer(pattern, string):返回一个迭代器,包含所有匹配正则表达式的子串。 re.sub(pattern, repl, string):将字符串中匹配正则表达式的部分替换为 repl。 re.split(pattern, string):根据正则表达式匹配的子串将字符串分割,...
所以我们只需要在列表中存储电话号码的数字部分即可,然后将每次遍历得到的结果存储到列表中: for循环提取特定的电话号码: for grops in telRegex.findall(text):...,就可以提取到特定的电话号码和电子邮箱了!...marches.append(grops) pyperclip.copy('\n'.join(marches)) print('\n'.join(marches)) 程序不...
>>> date1 = '2018-06-27' >>> date2 = '2018-06-nock...' >>> import re >>> # 简单匹配:\d+表示匹配一个或多个数字 >>> print('match yes') if re.match(r'\d+-\d+-\d+', date1) else...()编译你想匹配的正则表达式字符串内容,然后再使用match(),findall()和finditer()方法的...
