Create a MultiIndex:

>>> import pandas as pd
>>> mi = md.Index(pd.MultiIndex.from_arrays((list('abc'), list('def')), names=['level_1', 'level_2']))

Get level values by supplying level as either integer or name:

>>> mi.get_level_values(0).execute()
Index(['a', 'b', 'c'], dtype='object', name='level_1')
>>> mi.get_level_values('level_2').execute()
Index(['d', 'e', 'f'], dtype='object', name='level_2')
