I suspect the problem lies with Eric4, Notepad++ and Gedit. Do you
perhaps have to manually tell them that the file uses Windows line
separators?
I recommend opening the file in a hex editor and seeing for yourself what
line separators are used.
Example with this code:
----------------------------------------------
# -*- coding: utf-8 -*-
import os
L_SEP = os.linesep
def write():
strings = ['# -*- coding: utf-8 -*-\n',
'import os\n',
'import sys\n']
with open('writetest.py', 'w') as outf:
for s in strings:
outf.write(s.replace('\n', L_SEP))
write()
----------------------------------------------
The syntax `s.replace('\n', L_SEP)`is required for portability.
I don't think it is. Behaviour is a little different between Python 2 and
3, but by default, Python uses "Universal Newlines". When you open a file
in text mode, arbitrary line separators should be automatically
translated to \n when reading, and \n will be automatically translated to
os.line_sep when writing.

http://docs.python.org/2/library/functions.html#open
Some further discussion here:
http://stackoverflow.com/questions/12193047/is-universal-newlines-mode-
supposed-to-be-default-behaviour-for-open-in-python
In fact, in my code, the original file is open in binary mode, the line
separator is translate to \n and it is parsed by the module tokenise.
I'm not a Windows user but my code must be run also on Win, this is the
reason of the usage of os.linesep in writting.
So, now I found the solution, just write the file in binary mode and now
it is correctly open with all the editors.
Thanks all
