Python String splitlines() method is used to split the lines at line boundaries. The function returns a list of lines in the string, including the line break(optional).

Syntax: 

string.splitlines([keepends])

Parameters:

keepends (optional): When set to True line breaks are included in the resulting list. This can be a number, specifying the position of line break or, can be any Unicode characters, like “\n”, “\r”, “\r\n”, etc as boundaries for strings.

Return Value: 

Returns a list of the lines in the string, breaking at line boundaries.

splitlines() splits on the following line boundaries:

Representation

Description

\nLine Feed
\rCarriage Return
\r\nCarriage Return + Line Feed
\x1cFile Separator
\x1dGroup Separator
\x1eRecord Separator
\x85Next Line (C1 Control Code)
\v or \x0bLine Tabulation
\f or \x0cForm Feed
\u2028Line Separator
\u2029Paragraph Separator

Example 1

Python3




# Python code to illustrate splitlines()
string = "Welcome everyone to\rthe world of Geeks\nGeeksforGeeks"
  
# No parameters has been passed
print (string.splitlines( ))
  
# A specified number is passed
print (string.splitlines(0))
  
# True has been passed 
print (string.splitlines(True))

Output: 

['Welcome everyone to', 'the world of Geeks', 'GeeksforGeeks']
['Welcome everyone to', 'the world of Geeks', 'GeeksforGeeks']
['Welcome everyone to\r', 'the world of Geeks\n', 'GeeksforGeeks']

Example 2

Python3




# Python code to illustrate splitlines()
string = "Cat\nBat\nSat\nMat\nXat\nEat"
  
# No parameters has been passed
print (string.splitlines( ))
  
# splitlines() in one line
print('India\nJapan\nUSA\nUK\nCanada\n'.splitlines())

Output: 

['Cat', 'Bat', 'Sat', 'Mat', 'Xat', 'Eat']
['India', 'Japan', 'USA', 'UK', 'Canada']

Example 3: Practical Application

In this code, we will understand how to use the concept of splitlines() to calculate the length of each word in a string. 

Python3




# Python code to get length of each words
def Cal_len(string):
      
    # Using splitlines() divide into a list
    li = string.splitlines()
    print (li)
      
    # Calculate length of each word
    l = [len(element) for element in li]
    return l
  
# Driver Code    
string = "Welcome\rto\rGeeksforGeeks"
print(Cal_len(string))

Output: 

['Welcome', 'to', 'GeeksforGeeks']
