Series-str.rpartition() function

The str.rpartition() function is used to split the string at the last occurrence of sep.

This method splits the string at the last occurrence of sep, and returns 3 elements containing the part before the separator, the separator itself, and the part after the separator. If the separator is not found, return 3 elements containing two empty strings, followed by the string itself.

Syntax:

Series.str.rpartition(self, sep=' ', expand=True)

Pandas Series: str.rpartition() function

Parameters:

Name	Description	Type/Default Value	Required / Optional
sep	String to split on.	str or compiled regex	Required
pat		str Default Value: whitespace	Required
expand	If True, return DataFrame/MultiIndex expanding dimensionality. If False, return Series/Index.	bool Default Value: True	Required

Returns: DataFrame/MultiIndex or Series/Index of objects

Example:

Python-Pandas Code:

import numpy as np
import pandas as pd
s = pd.Series(['Albert Junior Labuschagne', 'Jason Pitt-Rivers'])
s

Output:

0    Albert Junior Labuschagne
1            Jason Pitt-Rivers
dtype: object

Example - To partition by the last space instead of the first one:

Python-Pandas Code:

import numpy as np
import pandas as pd
s = pd.Series(['Albert Junior Labuschagne', 'Jason Pitt-Rivers'])
s.str.rpartition()

Output:

              0	1	      2
0	Albert Junior		Labuschagne
1	Jason		        Pitt-Rivers
