SyntaxError on py-execute-region

[Yuri Goncharov]

I got error:
SyntaxError: Non-ASCII character '\xd0' in file /temp/python-abcd.py on line 2, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

There are patch:

Hi Yuri,

don't think it's a python-mode bug.

As you're pointing to the pep, it's seems good to have the encoding declared.

BTW here my python-files always start with

#! /usr/bin/env python
# -*- coding: utf-8 -*-

However, providing this seems not the task of python-mode, it's at the user to decide.

Andreas,

I can confirm the bug Yuri reported and it doesn't help to have # -*- coding: utf-8 -*- at the top of a file, since it isn't considered by py-execute-region if it's not included in the selection. which defies the purpose of evaluating a region.

An example. Give this file
{{{
# -*- coding: utf-8 -*-
print "ö"
}}}
Using py-execute-buffer works fine, since it send
  # -*- coding: utf-8 -*-
to the interpreter.
Now select `print "ö"' and use py-execute-region. It will trigger the error mention by Yuri, since it doesn't send the encoding information to the interpreter.

Best,
Maik

Hi,

while hunting bug #691542 --SyntaxError on py-execute-region--

consider to drop const `py-execute-region'.

Assume, if used at all, things should rather be fixed at the source than
dealt with here.

Should somebody use it, please send a note.

Thanks

Andreas

Typo: py-emacs-features

is at stake

Agreed. py-emacs-features seems useless.
