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.
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.
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.
NOTE: 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
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 statement looks for @, which doesn’t exist. So, it returns the tuple as (”, ”, ‘Tutorial Gateway’)
