os.linesep

constants

The line terminator on this system: '\n' on Unix and macOS, '\r\n' on Windows.

Syntax

os.linesep  # '\n' на Unix, '\r\n' на Windows

Text files do not need os.linesep and are even harmed by it: a file in text mode translates '\n' to the platform line ending itself, so writing os.linesep on Windows produces '\r\r\n'. Write '\n'. os.linesep is useful when working with bytes or in binary mode.

Examples

import os
print(repr(os.linesep))  # → ? '\n' на Unix, '\r\n' на Windows
with open('t.txt', 'w', encoding='utf-8') as f:
    f.write('a\nb\n')  # в текстовом режиме пишут '\n' — перевод сделает файл
with open('t.txt', encoding='utf-8') as f:
    print(f.read().splitlines())  # → ['a', 'b']
