and there is: open your output file in binary mode; then it won't
convert every \n to \r\n.

writing:
| >>> f = open('unixlf.txt', 'wb')
| >>> f.write('foo\n')
| >>> f.write('bar\n')
| >>> f.close()

checking:
| >>> f = open('unixlf.txt', 'rb')
| >>> x = f.read()
| >>> x
| 'foo\nbar\n'
| >>> len(x)
| 8

BTW:
| >>> '\n' is '\x0a'
| True
