Python String rsplit() Usage and Examples

Python String Methods

The rsplit() method splits the string at the specified separator from the right and returns a list of strings.

The syntax of rsplit() is:

str.rsplit([separator[, maxsplit]])

rsplit() parameters

The rsplit() method can accept at most2One parameter:

• separator(Optional)-This is a separator. The method's purpose is: to split the string from the right at the specified separator.

• If separator is not specified, any whitespace (spaces, newline characters, etc.) string is considered as a separator.

• maxsplit(Optional)- maxsplit defines the maximum number of splits.
  The default value is maxsplit-1means the split count is unlimited.

rsplit() return value

The rsplit() method splits the string into a list starting from the right.
If "maxsplit" is not specified, this method will return the same result as the split() method.
Note: If maxsplit is specified, the list will contain one more element than the specified number.

Example1How does rsplit() work in Python?

text = 'Love thy neighbor'
# Split at space
print(text.rsplit())
grocery = 'Milk, Chicken, Bread'
# Split at ','
print(grocery.rsplit(', '))
# Split at ':'
print(grocery.rsplit(':'))

When running the program, the output is:

['Love', 'thy', 'neighbor']
['Milk', 'Chicken', 'Bread']
['Milk, Chicken, Bread']

If maxsplit is not specified, the behavior of rsplit() is similar to split().

Example2How does split() work when maxsplit is specified?

grocery = 'Milk, Chicken, Bread, Butter'
# maxsplit:　2
print(grocery.rsplit(', '))　2))
# maxsplit:　1
print(grocery.rsplit(', '))　1))
# maxsplit:　5
print(grocery.rsplit(', '))　5))
# maxsplit: 0
print(grocery.rsplit(', ', 0))

When running the program, the output is:

['Milk, Chicken', 'Bread', 'Butter']
['Milk, Chicken, Bread', 'Butter']
['Milk', 'Chicken', 'Bread', 'Butter']
['Milk, Chicken, Bread, Butter']

If maxsplit is specified, the list will contain at most maxsplit+1Project.
