Python rpartition

by

Python rpartition is one of the Python String Method, used to partition the given string using the specified separator and return a tuple with three arguments.

This Python rpartition function starts looking for the separator from the Right-Hand side. Once rpartition finds the separator, it returns the string before the Separator as Tuple Item 1, Separator itself as Tuple Item 2 and string after the Separator (or remaining string) as Tuple Item 3. In this section, we discuss how to write rpartition in Python Programming with example.

Syntax of a rpartition Function in Python

The syntax of the string rpartition method in Python Programming Language is

String_Value.rpartition(Separator)
  • String_Value: A valid String variable or you can use the String directly.
  • Separator: This argument is required and if you forget this argument, python throw TypeError.

If you pass the non-existing item as the separator, then rpartition return two empty strings as Tuple Item 1, Item 2, followed by the whole string as Tuple Item 3.

Return Value

Python rpartition function returns Tuple with three arguments. For example, If we have A*B*C and If we use * as a separator, rpartition function searches for * from right to left. Once it finds * symbol, it returns the string before the * symbol as Tuple Item 1 (A*B), * as Tuple Item 2, and remaining string as Tuple Item 3 (C).

TIP: Even though there are multiple occurrences of the separator, the rpartition function looks for the first occurrence from the right side.

Python rpartition method Example

The following set of examples helps to understand the rpartition Function in Python Programming Language.

# Python rpartition Method Example
 
Str1 = 'Tutorial Gateway Website'
Str2 = 'Free-Tutorials-On-Python-Language'
Str3 = '[email protected]@mailaccount.com'
 
Str4 = Str1.rpartition(' ')
print("Right Partitioning String 1 = ", Str4)

Str5 = Str2.rpartition('-')
print("Right Partitioning String 2 = ", Str5)

Str6 = Str3.rpartition('@')
print("Right Partitioning String 3 = ", Str6)

#Performing Python rpartition function directly
Str7 = 'Python.Images.png'.rpartition('.')
print("Right Partitioning String 7 = ", Str7)

# Non Existing Item
Str8 = 'Tutorial Gateway'.rpartition('@')
print("Right Partitioning String 8 = ", Str8)

OUTPUT

Python RPartition Method

ANALYSIS

The following Python rpartition statement partitions the Str1 string into multiple parts based on the separator we specified. That is Empty Space and prints the output.

Str4 = Str1.rpartition(' ')
print("Right Partitioning String 1 = ", Str4)

It partitions the Str2 string into multiple parts based on the ‘-‘ symbol and prints the output.

Str5 = Str2.rpartition('-')
print("Right Partitioning String 2 = ", Str5)

The following statement partition the Str3 string into multiple parts based on the ‘@’ symbol and prints the output.

Str6 = Str3.rpartition('@')
print("Right Partitioning String 3 = ", Str6)

Here, we used the rpartition function directly on String

Str7 = 'Python.Images.png'.rpartition('.')
print("Right Partitioning String 7 = ", Str7)

If you try something like,

Str8 = 'Tutorial Gateway'.rpartition('@')
print("Right Partitioning String 8 = ", Str8)

The above Python statement looks for @, which doesn’t exist. So, it returns the Tuple as (”, ”, ‘Tutorial Gateway’)

TIP: Please refer to Python partition article in Python String Methods to understand the Partition method, which performs the same operation but from left to right.
