Some inconsistencies with the Dask version may exist.

Examples

>>> idx = pd.Index(['Ant', 'Bear', 'Cow'], name='animal')  

By default, the original index and original name is reused.

>>> idx.to_series()  
animal
Ant      Ant
Bear    Bear
Cow      Cow
Name: animal, dtype: object

To enforce a new index, specify new labels to index:

>>> idx.to_series(index=[0, 1, 2])  
0     Ant
1    Bear
2     Cow
Name: animal, dtype: object

To override the name of the resulting column, specify name:

>>> idx.to_series(name='zoo')  
animal
Ant      Ant
Bear    Bear
Cow      Cow
Name: zoo, dtype: object
