Python: Split a string on the last occurrence of the delimiter

Last update on June 12 2025 12:43:38 (UTC/GMT +8 hours)

Split string on last delimiter occurrence.

Write a Python program to split a string on the last occurrence of the delimiter.

Sample Solution:

Python Code:

# Define a string 'str1' containing a comma-separated list of characters.
str1 = "w,3,r,e,s,o,u,r,c,e"

# Split the string 'str1' into a list of substrings using the ',' separator, starting from the right.
# Split at most 1 time and print the result.
print(str1.rsplit(',', 1))

# Split the string 'str1' into a list of substrings using the ',' separator, starting from the right.
# Split at most 2 times and print the result.
print(str1.rsplit(',', 2))

# Split the string 'str1' into a list of substrings using the ',' separator, starting from the right.
# Split at most 5 times and print the result.
print(str1.rsplit(',', 5)) 

Sample Output:

['w,3,r,e,s,o,u,r,c', 'e']                                                                                    
['w,3,r,e,s,o,u,r', 'c', 'e']                                                                                 
['w,3,r,e,s', 'o', 'u', 'r', 'c', 'e']
