Python在div，dl标签中抓取一个标签

Question

我正在制作电影专家的评论稿。我用Jupiter Notebook编写了此代码。 我想刮掉这部分。

我尝试过

soup.find('div', 'reporter_line')

和

soup.find('dl','p_review')

但它不起作用。

  

AttributeError：“ NoneType”对象没有属性“ find_all”

如何解决此代码以抓取此文本？

    data = {'title':[title],'rname':[rname], 'rreview':[rreview]}

df.to_csv('./reviewr.csv', sep=',', encoding='utf-8-sig')

Answer 1

title或rname为None，因此您得到'AttributeError：'NoneType'对象没有属性'find_all'。 试试这个来拉出'reporter_line'

soup.find('div', {'class' : 'reporter_line'})

如果标题标签（h3）也具有“ h_movie”作为类，则

soup.find('div', {'class' : 'h_movie'})

或者如果'h_movie'是'id'，请使用：

soup.find(id='h_movie')

希望它能起作用：）
