is script run from desktop or console

#!/usr/bin/env python
import os

# Returns '1' for /sbin/init if our script was launched from a desktop-environment and will return a process-id higher than 1 if the script was launched from a console - This way, we now have a method to deliver GUI-output / console-output accordingly!
parentprocessid = os.getppid()

create notify-bubble using dbus

#!/usr/bin/env python

import dbus
import sys

# Use session bus
session_bus = dbus.SessionBus()

# Use notifications object
notifications_object = session_bus.get_object('org.freedesktop.Notifications', 
'/org/freedesktop/Notifications')
notifications_interface = dbus.Interface(notifications_object, 'org.freedesktop.Notifications')

# Sample notification
notification_id = notifications_interface.Notify(sys.argv[0], 0, , 'Sample summary', 
'Sample body', dbus.Array([], signature='s'), dbus.Array([], signature='(sv)'), -1)

# Sample notification with actions and hints
notification_id = notifications_interface.Notify(sys.argv[0], 0, , 'Sample summary', 
'Sample body', ['sample', 'Sample action'], {'x': 100, 'y': 100}, -1)

create icon in systray with notification-bubble using pynotify

#!/usr/bin/env python 

import gtk
import pygtk
import pynotify

def callback(icon):
   notification.show()

pynotify.init("Woofgui")
notification = pynotify.Notification("Title", "Text in body", "dialog-warning")
# the dialog-warning specifies icon type
notification.set_urgency(pynotify.URGENCY_NORMAL)
notification.set_timeout(pynotify.EXPIRES_DEFAULT)
# _NEVER sets timeout to never, user has to click

icon = gtk.status_icon_new_from_stock(gtk.STOCK_ABOUT)
icon.connect('activate', callback)
notification.attach_to_status_icon(icon)

gtk.main()

test for desktop-environment

#!/usr/bin/env python
import os

# Returns 'gnome' or 'kde' or ...
desktoptype = os.environ.get('DESKTOP_SESSION')

find out user-language

#!/usr/bin/env python
import os

# e.g. returns de_DE.UTF-8
usedlanguage = os.environ.get('LANG')

get user-home directory

#!/usr/bin/env python
import os

# Returns /home/username
homepath = os.environ.get('HOME')

example wxpython textentry

#!/usr/bin/env python
import wx

app = wx.PySimpleApp()
dlg = wx.TextEntryDialog(None, 'Enter value', 'Title', )
if dlg.ShowModal() == wx.ID_OK:
    val = dlg.GetValue() # this line should be indented
dlg.Destroy()
print "you have entered %s" % val

(OLD: test if kde or gnome)

#!/usr/bin/env python

import subprocess as data

p1 = data.Popen(["ps", "-e"], stdout = data.PIPE)
p2 = data.Popen(["grep", "kdesktop"], stdin = p1.stdout, stdout = data.PIPE)

if p2.stdout.read() != :
   print 'kde'
else:
   print 'gnome'
