    levelint/level name or list thereof, optional
    drop_levelbool, default True

      If `False`, the resulting index will not drop any level.

  Returns:
    tuple

      A 2-tuple where the elements :

      Element 0: int, slice object or boolean array.

      ...                                names=['A', 'B'])

      >>> mi.get_loc_level('b')
      (slice(1, 3, None), Index(['e', 'f'], dtype='object', name='B'))

      >>> mi.get_loc_level('e', level='B')
      (array([False,  True, False]), Index(['b'], dtype='object', name='A'))

      >>> mi.get_loc_level(['b', 'e'])
