Examples

>>> import maxframe.dataframe as md
>>> mi = md.MultiIndex.from_arrays(
... [[1, 2], [3, 4], [5, 6]], names=['x', 'y', 'z'])
>>> mi.execute()
MultiIndex([(1, 3, 5),
            (2, 4, 6)],
            names=['x', 'y', 'z'])

>>> mi.droplevel().execute()
MultiIndex([(3, 5),
            (4, 6)],
            names=['y', 'z'])

>>> mi.droplevel(2).execute()
MultiIndex([(1, 3),
            (2, 4)],
            names=['x', 'y'])

>>> mi.droplevel('z').execute()
MultiIndex([(1, 3),
            (2, 4)],
            names=['x', 'y'])

>>> mi.droplevel(['x', 'y']).execute()
Index([5, 6], dtype='int64', name='z')
