regex 正则表达式从一个句子中获取两个单词试试这个
试试on regex101.com。或者，您可以匹配整个单词，并使用$1将其替换为第一个字母：
re.match(pattern, string[, flags]) 判断pattern 是否在字符串开头位置匹配。对于 RegexObject,有: match(string[, pos[, endpos]]) match() 函数只在字符串的开始位置尝试匹配正则表达式,也就是只报告从位置 0 开始的匹配情况,而 search() 函数是扫描整个字符串来查找匹配。如果想要搜索整个字符串来寻找匹配,...

if(std::regex_match("subject",std::regex("(sub).(.*)"))){ std::cout <<"string literal matched\n"; } std::string s("subject"); std::regex e("(sub)(.*)"); if(std::regex_match(s,e)){ std::cout <<"string literal matched\n"; ...
I was going to to that, however, sometimes I am looking for more than two works and would have to build all the combinations. For the record to do the example that you gave above in MYSQL, it would be easier to do as follows: select * from sp where sp regexp('word1') and sp...
