尝试/捕获不捕获HTTPError

Question

我有一些基本代码尝试使用BeautifulSoup请求页面：

from bs4 import *
from urllib.request import urlopen

try:
    soup = BeautifulSoup(urlopen('http://badsite.com/404'))
except urllib.exceptions.HTTPError:
    pass

这仍然引发：

---------------------------------------------------------------------------
HTTPError                                 Traceback (most recent call last)
<ipython-input-24-a0aa8eb7a9ee> in <module>

我用urllib.exceptions.HTTPError代替了requests.HTTPError和requests.exceptions.HTTPError。它们所有人仍然无法捕获错误。如何正确捕获HTTPError？
