如何使用dataframe (Pandas)给出3D矩阵维度的名称

import pandas as pd

# 创建3D矩阵数据
data = [[[1, 2, 3], [4, 5, 6], [7, 8, 9]],
        [[10, 11, 12], [13, 14, 15], [16, 17, 18]],
        [[19, 20, 21], [22, 23, 24], [25, 26, 27]]]

# 创建多级索引
index = pd.MultiIndex.from_product([['A', 'B', 'C'], ['X', 'Y', 'Z'], ['I', 'II', 'III']],
                                   names=['Dim1', 'Dim2', 'Dim3'])

# 创建DataFrame
df = pd.DataFrame(data, index=index, columns=['Value'])

# 获取3D矩阵维度的名称
dim_names = df.index.names
print(dim_names)

['Dim1', 'Dim2', 'Dim3']
