Python String splitlines() Method

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

Syntax:

string.splitlines([keepends])

Parameters:

keepends (Optional) : When set to True, newlines will be included in the resulting list. This can be a number specifying line breaks, or any Unicode character such as “n”, “r”, “rn”, etc., used as a string boundary.

Return Value:

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

splitlines() splits on the following line boundaries:

Example 1

# Python code to illustrate splitlines()
string = "Welcome everyone torthe world of GeeksnGeeksforGeeks"
  
# 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 tor', 'the world of Geeksn', 'GeeksforGeeks']

Example 2

# Python code to illustrate splitlines()
string = "CatnBatnSatnMatnXatnEat"
  
# No parameters has been passed
print (string.splitlines( ))
  
# splitlines() in one line
print('IndianJapannUSAnUKnCanadan'.splitlines())

Output:

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

Example 3: Practical Application

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

# Python code to get the length of each word
def Cal_len(string):
        
    # Using splitlines() to divide into a list
    li = string.splitlines()
    print (li)
      
# Calculate length of each word
l = [len(element) for element in li]
Return l
  
#DriverCode
string = "WelcomertorGeeksforGeeks"
print(Cal_len(string))

Output:

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