Writing Multi-Line Strings to Files in Python

Writing multiple lines to a text file in Python requires specifying newlines in the string. Here's how you can accomplish this:

Using '\n':

The most common method is to use the backslash-n ('\n') character. It represents a newline in most operating systems, including Windows, Unix, and macOS.

with open('myfile.txt', 'w') as f:
    f.write("Line 1\nLine 2\nLine 3")

Using '\n' will generally suffice in most situations.

Using 'os.linesep':

For a more accurate approach, you can use the 'os.linesep' property. It returns the appropriate newline character based on the current platform.

import os

with open('myfile.txt', 'w') as f:
    f.write("Line 1{}Line 2{}Line 3".format(os.linesep, os.linesep))

Note:

When writing to files using Python's file API, it's generally recommended to use '\n' for newlines. Python automatically handles the conversion to the appropriate platform-specific newline character.
