Python Pandas Dataframe:根据第二个数据帧中的条件(日期范围和条件)选择条目

import pandas as pd

df1 = pd.DataFrame({'日期': ['2022-01-01', '2022-01-02', '2022-01-03'],
                    '数值': [10, 20, 30]})

df2 = pd.DataFrame({'日期': ['2022-01-01', '2022-01-02', '2022-01-03'],
                    '条件': ['A', 'B', 'C']})

df1['日期'] = pd.to_datetime(df1['日期'])
df2['日期'] = pd.to_datetime(df2['日期'])

start_date = '2022-01-02'
end_date = '2022-01-03'
condition = 'B'

selected_items = df1[(df1['日期'] >= start_date) & (df1['日期'] <= end_date) & (df2['条件'] == condition)]
