识别数据帧中除了多索引中的date索引值之外相同的行？

import pandas as pd
import numpy as np

data = {'date': ['2022-01-01', '2022-01-01', '2022-01-02', '2022-01-02'],
        'index1': ['A', 'A', 'B', 'B'],
        'index2': ['X', 'Y', 'X', 'Y'],
        'value': [1, 2, 3, 4]}
df = pd.DataFrame(data)

grouped = df.groupby(['index1', 'index2']).size().reset_index(name='count')

duplicates = grouped[grouped['count'] > 1]

print(duplicates)
