In this article, we will learn about the Python String rsplit() method with the help of examples.

rsplit() Syntax

The Syntax of rsplit() method is:

str.rsplit(separator, maxsplit)

rsplit() Parameters

The rsplit() method takes two parameters, and both are optional.

• separator (optional) – Delimiter after which the string split should happen . If not provided, whitespace is taken as a separator, and the string will split at whitespaces.
• maxsplit (optional) – An integer that tells us the maximum number of times the split should happen. If not provided, the default value is -1, which means there is no limit on the number of splits.

rsplit() Return Value

The rsplit() method returns the list of strings after breaking the given string at the separator from the right side

Example 1: How rsplit() works in Python?

If we do not specify maxsplit to rsplit() method it behaves exactly like split() method as shown in below example.

# splits by whitespace
text = "Python is fun"
print(text.rsplit())

# splits the text after 'is' string
text = "Python is fun"
print(text.rsplit('is'))

# cannot split as the character is not found
text = "Python is fun"
print(text.rsplit('|'))

# splits by comma
fruits ="Apple, Grapes, Orange, Watermelon"
print(fruits.rsplit(','))

Output

['Python', 'is', 'fun']
['Python ', ' fun']
['Python is fun']
['Apple', ' Grapes', ' Orange', ' Watermelon']

Example 2: How split() works when maxsplit is specified?

# splits by whitespace
text = "Python is really fun"
print(text.rsplit(' ', 1))

# splits by comma
fruits = "Apple, Grapes, Orange, Watermelon"
print(fruits.rsplit(',', 0))

# splits by comma
fruits = "Apple, Grapes, Orange, Watermelon"
print(fruits.rsplit(',', 1))

# splits by comma
fruits = "Apple, Grapes, Orange, Watermelon"
print(fruits.rsplit(',', 2))

# splits by comma
fruits = "Apple, Grapes, Orange, Watermelon"
print(fruits.rsplit(',', 3))

Output

['Python is really', 'fun']
['Apple, Grapes, Orange, Watermelon']
['Apple, Grapes, Orange', ' Watermelon']
['Apple, Grapes', ' Orange', ' Watermelon']
['Apple', ' Grapes', ' Orange', ' Watermelon']
