Python - 属性错误 : 'NoneType' object has no attribute 'get_text'

Question

我正在学习 bs4 的一些教程。我正在尝试使用“a”获取以下示例的 get_text()。教程返回结果 McDermott International 和 MDR 没有问题。但是当我这样做时，我得到了 AttributeError: 'NoneType' object has no attribute 'get_text'。请帮忙。非常感谢!

with open('Energy.htm') as f:
    soup = BeautifulSoup(f,"lxml")
energylist = soup.find_all('td', {"style" : "text-align:left;"})
for stock in energylist:
    try:
        stock_name = stock.find('a').get_text()
    except:
        stock_name = ''

#sample of the energylist
[<td style="text-align:left;">
<a href="/finance?q=NYSE:MDR&amp;ei=nblKWaDrOs7AmgH0l7S4Bg">McDermott 
International</a>
</td>, <td style="text-align:left;">
<a href="/finance?q=NYSE:MDR&amp;ei=nblKWaDrOs7AmgH0l7S4Bg">MDR</a>
</td>, <td style="text-align:left;">
<a href="/finance?q=NYSE:EQT&amp;ei=nblKWaDrOs7AmgH0l7S4Bg">EQT</a>
</td>, <td colspan="8" style="text-align:left;">
Companies <b>1 - 20</b> of about <b>476</b> in <b>Energy</b> 
</td>]

Answer 1

energylist 似乎有一些标签不包含 anchor 标签。您需要添加一个条件来妥善处理这些问题:

for stock in energylist:
    try:
        stock_name = stock.find('a').get_text()
        ... # more code
    except AttributeError:
        pass
