Python String rsplit() Method

Python String rsplit() method returns a list of strings after breaking the given string from the right side by the specified separator. It's similar to the split() method in Python, but the difference is that rsplit() starts splitting from the end of the string rather than from the beginning. Example:

s = "tic-tac-toe"
print(s.rsplit('-'))

['tic', 'tac', 'toe']

Explanation:

• rsplit() method in Python is used to split a string from the right (the end of the string) based on a specified separator.
• The method returns a list of substrings.

Syntax of rsplit() method

str.rsplit(separator, maxsplit)

Parameters:

• separator: The is a delimiter. The string splits at this specified separator starting from the right side. If not provided then any white space character is a separator.
• maxsplit: It is a number, which tells us to split the string into a maximum of provided number of times. If it is not provided then there is no limit.  

Return Type: Returns a list of strings after breaking the given string from the right side by the specified separator.

Error: We will not get any error even if we are not passing any argument.

Note: Splitting a string using Python String rsplit() but without using maxsplit is same as using String split() Method

Examples of rsplit() method

1. Splitting String Using Python String rsplit() Method

Splitting Python String using different separator characters.

# splits the string at index 12 i.e.: the last occurrence of g
word = 'geeks, for, geeks'
print(word.rsplit('g', 1))
# Splitting at '@' with maximum splitting as 1
word = 'geeks@for@geeks'
print(word.rsplit('@', 1))

['geeks, for, ', 'eeks']
['geeks@for', 'geeks']

Explanation:

• The rsplit('g', 1) method splits the string at the last occurrence of the character 'g' (starting from the right). Here, the last 'g' appears at index 12 (geeks, for, geeks).
• The rsplit('@', 1) method splits the string at the last occurrence of '@'. The last '@' appears before the second "geeks".

2. Splitting a String using a multi-character separator argument.

Here we have used more than 1 character in the separator string. Python String rsplit() Method will try to split at the index if the substring matches from the separator.

word = 'geeks, for, geeks, pawan'
# maxsplit: 0
print(word.rsplit(', ', 0))
# maxsplit: 4
print(word.rsplit(', ', 4))

['geeks, for, geeks, pawan']
['geeks', 'for', 'geeks', 'pawan']

Explanation:

• maxsplit = 0, it means no splitting occurs. The output remains the original string inside a list: ['geeks, for, geeks, pawan'].
• maxsplit = 4 means the string will be split at most 4 times from the right. The ', ' (comma followed by a space) is used as the separator.
