检查pandas列是否包含另一个数据框中的文本并替换值

import pandas as pd

df_main = pd.DataFrame({'col1': ['apple', 'banana', 'orange', 'grape'],
                        'col2': ['cat', 'dog', 'elephant', 'lion']})

df_replace = pd.DataFrame({'col1': ['banana', 'grape'],
                           'replacement': ['fruit', 'fruit']})

mask = df_main['col1'].str.contains('|'.join(df_replace['col1']), na=False)

df_main.loc[mask, 'col1'] = df_main.loc[mask, 'col1'].replace(dict(zip(df_replace['col1'], df_replace['replacement'])))
