Python Split String by New Line

Python – Split String by New Line

You can split a string in Python with new line as delimiter in many ways.

In this tutorial, we will learn how to split a string by new line character \n in Python using str.split() and re.split() methods.

Examples

1. Split given string by new line using str.split()

In this example, we will take a multiline string string1. We will call the split() method on this string with new line character \n passed as argument. split() method splits the string by new line character and returns a list of strings.

Python Program

string1 = '''Welcome
to
pythonexamples.org'''

#split string by single new-line
chunks = string1.split('\n')

print(chunks)

Run Code Online

Output

['Welcome', 'to', 'PythonExamples.org']

The string can also contain \n characters in the string as shown below, instead of a multi-line string with triple quotes.

Python Program

str = 'Welcome\nto\nPythonExamples.org'

#split string by single new-line
chunks = str.split('\n')

print(chunks)

Run Code Online

Output

['Welcome', 'to', 'PythonExamples.org']

2. Split given string by new line using re.split()

In this example, we will split the string by new line using split() method of regular expression re package.

To use re package, we have to import it at the start of our program.

Python Program

import re

string1 = '''Welcome
to
pythonexamples.org'''

#split string by single new-line
chunks = re.split('\n', string1)

print(chunks)

Run Code Online

Output

['Welcome', 'to', 'pythonexamples.org']

3. Split given string by one or more newline characters

In this example, we will take a string with substrings separated by one or more new line characters. We will use re package to split the string with one or more new line characters as delimiter. The regular expression that represents one or more new line characters is \n+. We shall pass this expression and the string as arguments to re.split() method.

The syntax of re.split() method is re.split(regular_expression, string). The function returns list of substrings split from string based on the regular_expression.

Python Program

import re

str = '''Welcome

to




PythonExamples.org'''

#split string by one or more new-line
chunks = re.split('\n+', str)

print(chunks)

Run Code Online

Regular Expression \n+ represents one or more adjacent new lines. So, one or more new lines is considered as a separator between splits.

Output

['Welcome', 'to', 'PythonExamples.org']

Summary

In this tutorial of Python Examples, we learned how to split a string by new line using String.split() and re.split() methods.
