From python official website I found this :
Python 3.4.0 alpha 2 was released on September 9th, 2013. This is a preview release of the next major release of Python, Python 3.4, and is not suitable for production environments.
Major new features of the 3.4 series, compared to 3.3
Python 3.4 includes a range of improvements of the 3.x series, including hundreds of small improvements and bug fixes. Major new features and changes in the 3.4 release series so far include:
PEP 435, a standardized "enum" module
PEP 442, improved semantics for object finalization
PEP 443, adding single-dispatch generic functions to the standard library
PEP 445, a new C API for implementing custom memory allocators
PEP 446, changing file descriptors to not be inherited by default in subprocesses...
#
-and enable line length checks use this instead#
-don't use multiple statements on the same line, like:if foo == 'test': do_test_thing()
one_test(); two_test()
... this is the correct way:if foo == 'test':
do_test_thing()
one_test()
two_test()
Also you can read about Blender 3D/Python and PEP 8 best practice here.
# coding: utf-8
You will see now something like this error:SyntaxError: invalid syntax
... but also will be point to the bad encoding character with : ^usertest@home:~$ python sunet.py
File "sunet.py", line 22
def __init__ ( self , a , b , c ) :

SyntaxError: invalid syntax
Any OS like Linux, Unix, Windows has environment variables.
Also any variables which must not be committed on a public code can be used in this way.
You can give this variables to your application.
Let's see one simple example about how to do that:
import os
ENV_VAR = os.environ.get("ENV_VAR", None)
if not ENV_VAR:
print "not ENV_VAR"
if ENV_VAR:
print "yes ! is ENV_VAR"
Now you can give this ENV_VAR to the script or not. See next...
usertest@home:~$ ENV_VAR=true python demo-env.py
yes ! is ENV_VAR
usertest@home:~$ python demo-env.py
not ENV_VAR
With Python 3 on Unix, environment variables are decoded using the file system encoding.
GObject is a object system used by GTK+, GStreamer and other libraries.
The new PyGObject 3.9.5 provides a convenient wrapper for use in Python programs when
accessing GObject libraries.
The news come from Simon Feltman - pygtk digest: I am pleased to announce version 3.9.5 of the Python bindings for
GObject. This is the third release of the 3.9.x series which will
eventually result in the stable 3.10 release for GNOME 3.10.
The new release is available from ftp.gnome.org.
