To split a string and get the last element in Python, you can use one of the four built-in functions in Python. I’ll go out below to get an idea for this topic. Please read the article in detail.
Split a string and get the last element in Python
Using the str.split() function
The first way to split a string and get the last element in Python is using the str.split() function. Look at the syntax and example below to understand more about it.
Syntax:
str.split()
Example:
- Initialize a string containing delimiters.
- Split the string using the str.split() function and get the last element of the string.
stringObj = 'visit#learnshareit#website'
# Use the str.split() function to split the string and get the last element in the string.
lastElement = stringObj.split('#')[-1]
print('The last element of the string:', lastElement)Output:
The last element of the string: websiteUsing the re.split() function
The second way is using the re.split() function. Its syntax and example is below.
Syntax:
re.split(RegEx, string, maxsplit)
Parameters:
- RegEx: regular expressions.
- string: string you want to compare.
- maxsplit: is the maximum number of splits. If not specified, Python defaults to an infinite number of splits.
Example:
- Import the re module.
- Initialize a string containing delimiters.
- Split the string using the re.split() function and get the last element of the string.
import re
stringObj = 'visit#learnshareit#website'
# Use the re.split() function to split the string and get the last element in the string.
lastElement = re.split('#', stringObj)[-1]
print('The last element of the string:', lastElement)Output:
The last element of the string: websiteUsing the str.rsplit() function
Syntax:
str.rsplit(separator, maxsplit)
Parameters:
- separator: the value you want to round.
- maxsplit: number of digits after the decimal point. The default is 0.
Example:
- Initialize a string containing delimiters.
- Split the string using the str.rsplit() function and get the last element of the string.
stringObj = 'visit#learnshareit#website'
# Use the str.rsplit() function to split the string and get the last element in the string.
lastElement = stringObj.rsplit('#')[-1]
print('The last element of the string:', lastElement)Output:
The last element of the string: websiteUsing the str.rpartition() function
Using the str.rpartition() function also is a great solution to split a string and get the last element.
Syntax:
string.rpartition(value)
Parameters:
- value: The string you want to search for. Required parameter.
The rpartition() function returns a string and splits the string into three parts before the specified string, the specified string, and after the specified string.
Example:
- Initialize a string containing delimiters.
- Split the string using the str.rpartition() function and get the last element of the string.
stringObj = 'visit#learnshareit#website'
# Use the str.rpartition() function to split the string and get the last element in the string.
lastElement = stringObj.rpartition('#')[-1]
print('The last element of the string:', lastElement)Output:
The last element of the string: websiteSummary
Those are four ways to split a string and get the last element in Python. You can use one of them. They are all built-in functions in Python. If there is a better way, please comment below. We appreciate it.
