使用BS4获取属性名称而不是值(Getting attribute name rather than value with BS4)

 我已经设法提取了我正在抓取的网站的大部分各种属性，但是试图在div声明器本身中提取某些东西的价值。 
 
 具体来说，假设如下： 
 
<div class="item" data-color="red" data-itemid="abc">Red Slippers</div>
 
 我在data-itemid> abc中的值之后。 
 
 我似乎无法得到一些没有看到div内部值的东西：即Red Slippers，这不是我追求的。 
 
 没试过，我试过以下内容： 
 
 item_id = soup.find('data-itemid') 
 
 有任何想法吗？ 

I have managed to pull out most of the various attributes of a site I am scraping, but have come short trying to extract the value of something within the div declarator itself. 
 
Specifically, assuming the following:
 
<div class="item" data-color="red" data-itemid="abc">Red Slippers</div>
 
I am after the value inside data-itemid > abc.
 
I cannot seem to get something that isn't looking at the value inside the div: i.e. Red Slippers, which is not what I am after. 
 
I have tried the following, without luck:
 
item_id = soup.find('data-itemid')
 
Any ideas?
