Python String rpartition() Method split the given string into three parts. rpartition() starts looking for separator from the right side, till the separator is found and return a tuple which contains part of the string before separator, the separator and the part after the separator.

Python String rpartition() Method Syntax

Syntax :  string.rpartition(separator)

Parameters :  

  • separator –  separates the string at the first occurrence of it.

Return Value : 

  1. It returns the part the string before the separator, separator parameter itself, and the part after the separator if the separator parameter is found in the string.
  2. It returns two empty strings, followed by the given string if the separator is not found in the string.

Example 1: Basic usage of Python String rpartition() Method

Here we are demonstrating the basic usages of Python String rpartition() Method

Python3




# String need to split
string1 = "Geeks@for@Geeks@is@for@geeks"
  
string2 = "Ram is not eating but Mohan is eating"
  
# Here '@' is a separator
print(string1.rpartition('@'))
  
# Here 'is' is separator
print(string2.rpartition('is'))


Output : 

('Geeks@for@Geeks@is@for', '@', 'geeks')
('Ram is not eating but Mohan ', 'is', ' eating')

Example 2: Using rpartition() Method on String when separator is not present

Python String rpartition() Method returns first 2 arguments as empty String if separator is not present in String

Python3




# String need to split
string = "Sita is going to school"
  
# Here 'not' is a separator which is not
# present in the given string
print(string.rpartition('not'))


Output : 

('', '', 'Sita is going to school')

Exceptions While Working With Python String rpartition()

TypeError: If a separator argument is not supplied, it will raise TypeError

Python3




# Python3 code explaining TypeError
# in rpartition()
  
string = "Bruce Waine is Batman"
  
# Nothing is passed as separator
print(string.rpartition())


Output : 

Traceback (most recent call last):
  File "/home/e207c003f42055cf9697001645999d69.py", line 7, in 
    print(str.rpartition())
TypeError: rpartition() takes exactly one argument (0 given)

ValueError: If the separator is an empty String, then rpartition() Method raises ValueError

Python3




string = "Bruce Waine is Batman"
  
# Nothing is passed as separator
print(string.rpartition(""))


Output : 

Traceback (most recent call last):
  File "/home/c8d9719625793f2c8948542159719007.py", line 7, in
