       Index([10, 20, 30], dtype='int64')

        In this example, we create a DataFrame with 3 rows and 3 columns,
        including Name, Age, and Location information. We set the index labels to
        be the integers 10, 20, and 30. We then access the `index` attribute of the
        DataFrame, which returns an `Index` object containing the index labels.

        >>> df.index = [100, 200, 300]
        >>> df
            Name  Age Location
        100  Alice   25  Seattle
        200    Bob   30 New York
        300  Aritra  35    Kona

        In this example, we modify the index labels of the DataFrame by assigning
        a new list of labels to the `index` attribute. The DataFrame is then
        updated with the new labels, and the output shows the modified DataFrame.
