数据框另一列中一列的搜索值

title列中有诸如dog之类的关键字，您必须在名为Text的列的同一行中进行搜索，然后创建一个称为句子的新列，并在找到该词的位置写上短语。

import pandas as pd

PAL = {'TITLE': ['CAT','DOG','MOUSE','BIRD'],
        'TEXT': ["""

I do not like cats. Birds fly through the sky. 
A mouse eat cheese and they are small""","""

        }

df = pd.DataFrame(PAL, columns = ['TITLE', 'TEXT'])

print (df)
