Solution

If you are attempting to find the text associated with the dt with the class attribute articleSubject, you can directly find it within the item.

By doing this:

>>> for item in a_data:
...     print item.find_all("dt",{"class":"articleSubject"})[0].text

This prints:

**시총 9조 `모바일 공룡` 다음카카오 합병 승인…업계 지각변동 예고**

for the above HTML. If you run this code against the URL in your code, you will get 20 results.

item.contents is a list with \n as the first item. So doing a find_all() on a new line character throws the AttributeError
