假设我有2个数据帧:

sub = pd.DataFrame(['Little Red', 'Grow Your', 'James Bond', 'Tom Brady'])
text = pd.DataFrame(['Little Red Corvette must Grow Your ego', 'Grow Your Beans', 'James Dean and his Little Red coat', 'I love pasta'])

一个包含各种主题,另一个包含我应该能够提取主题的文本

我希望文本数据框的输出为:

Text                                    | Subjects
Little Red Corvette must Grow Your ego  | Little Red, Grow Your
Grow Your Beans                         | Grow Your
James Dean and his Little Red coat      | Little Red
I love pasta                            | NaN

知道我怎么能做到这一点？我正在看这个问题:检查一个数据框中的单词是否出现在另一个数据框中(python 3,pandas), 但它并不完全是我想要的输出.谢谢
