在改代码中第94这里，我跑的时候提示没有对象属性group？？没太明白，代码是朋友发我的。我自己研究目前还没太懂

代码的目的是想自动把Excel中部分列的内容自动转移去Work文档去

Answer 1

res是正则匹配re.match(r'\d+[.\d][.\d]', title_second)的返回值，而res.group()提示“NoneType”通常是匹配没有成功，输入的字符串并没有所需的格式，可使用以下代码先对匹配结果进行验证，如果验证成功再调用group()方法：

if res:
    # 此处可继续执行后续的 doc_item.... 代码
    print('匹配的内容为：', res.group())
else:
    print('没有匹配的内容')
