pandas.Index.to_series

Index.to_series(index=None, name=None)[source]

Create a Series with both index and values equal to the index keys.

Parameters

index:Index, optional

Index of resulting Series. If None, defaults to original index.

name:str, optional

Name of resulting Series. If None, defaults to name of original index.

Returns

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
