String splitlines() Method in Python

Python String splitlines() Method

In Python, the splitlines() method is a built-in string method used to split a multi-line string into a list of individual lines. It identifies line breaks in the string and separates the lines accordingly. The method is useful when you want to process each line of a multi-line string separately.

Here's the syntax of the splitlines() method:

string.splitlines(keepends)

Parameters:

• keepends (optional): This parameter is a boolean value that determines whether to keep the line break characters at the end of each line. If keepends is set to True, the line break characters (e.g., \n or \r\n) will be retained; otherwise, they will be removed. By default, keepends is set to False.

Return value:

The splitlines() method returns a list containing the individual lines of the original string.

Here's an example of how to use the splitlines() method:

multiline_string = "This is line 1.\nThis is line 2.\nAnd this is line 3."

# Split the multi-line string into individual lines
lines = multiline_string.splitlines()

# Print each line separately
for line in lines:
    print(line)

Output:

This is line 1.
This is line 2.
And this is line 3.

If you want to keep the line break characters, you can pass keepends=True as an argument:

multiline_string = "This is line 1.\nThis is line 2.\nAnd this is line 3."

# Split the multi-line string into individual lines and keep line break characters
lines_with_breaks = multiline_string.splitlines(keepends=True)

# Print each line separately along with the line break characters
for line in lines_with_breaks:
    print(line)

Output:

This is line 1.
This is line 2.
And this is line 3.

Keep in mind that the splitlines() method does not modify the original string; it returns a new list of lines based on the line breaks present in the original string.
