Examples

>>> s = ps.Series(["dog", "cat", "monkey"], name="animal")
>>> s  
0       dog
1       cat
2    monkey
Name: animal, dtype: object
>>> s.rename_axis("index").sort_index()  
index
0       dog
1       cat
2    monkey
Name: animal, dtype: object

MultiIndex

>>> index = pd.MultiIndex.from_product([['mammal'],
...                                        ['dog', 'cat', 'monkey']],
...                                       names=['type', 'name'])
>>> s = ps.Series([4, 4, 2], index=index, name='num_legs')
>>> s  
type    name
mammal  dog       4
        cat       4
