Python String | splitlines()

Last Updated : 11 Jan, 2018

splitline() 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.

The below code shows the illustration of splitline() method.

Code #1

# 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']

Code #2

# 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']

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.

# 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']
