Python用beautifulsoup提取空标签

Question

我有以下循环，用于提取特定标签并将它们输入到目录中所有文件的 .csv 文件中。但是，有些文件有空标签，我收到以下错误

Traceback (most recent call last):  
  File "newsbank2.py", line 27, in <module>  
    author = fauthor.text  
AttributeError: 'NoneType' object has no attribute 'text'

对于这些情况，我怎样才能在 csv 文件中输入一个空白。我的代码如下。

path = "my directory"

for filename in os.listdir(path):

    if filename.endswith('.htm'):
        fname = os.path.join(path,filename)
        with open(fname, 'r') as f:
            soup = BeautifulSoup(f.read(),'html.parser')
            ftitle = soup.find("div", class_="title")
            title = ftitle.text
            fsource = soup.find("div", class_="source")
            source = fsource.text
            source = source.replace("Browse Issues", " ")
            publication = source.split("-")[0].strip()
            fauthor = soup.find("li", class_="author first")
            author = fauthor.text
            fbody = soup.find("div", class_="body")
            body = fbody.text
            f = csv.writer(open("testcsv","a"))
            f.writerow([title, source, author, body])

Answer 1

使用这样的东西：

title = ftitle.text if hasattr(ftitle, 'text') else ''

或以下也应该有效：

title = ftitle.text if ftitle else ''
