Examples
Getting the Index values of a DataFrame:
>>> df = pd.DataFrame([[1, 2, 3], [4, 5, 6], [7, 8, 9]], ... index=['a', 'b', 'c'], columns=['A', 'B', 'C']) >>> df A B C a 1 2 3 b 4 5 6 c 7 8 9 >>> df.index.get_values() array(['a', 'b', 'c'], dtype=object)
Standalone Index values:
>>> idx = pd.Index(['1', '2', '3']) >>> idx.get_values() array(['1', '2', '3'], dtype=object)
MultiIndex arrays also have only one dimension:
>>> midx = pd.MultiIndex.from_arrays([[1, 2, 3], ['a', 'b', 'c']], ... names=('number', 'letter')) >>> midx.get_values() array([(1, 'a'), (2, 'b'), (3, 'c')], dtype=object) >>> midx.get_values().ndim 1
