        style = win32con.WS_OVERLAPPED | win32con.WS_SYSMENU
        self.hwnd = CreateWindow( classAtom, "Taskbar", style, \

        except:

        Shell_NotifyIcon(NIM_ADD, nid)
        Shell_NotifyIcon(NIM_MODIFY, \

        # self.show_balloon(title, msg)
        time.sleep(10)
        DestroyWindow(self.hwnd)
    def OnDestroy(self, hwnd, msg, wparam, lparam):
        nid = (self.hwnd, 0)
        Shell_NotifyIcon(NIM_DELETE, nid)
        PostQuitMessage(0) # Terminate the app.

def balloon_tip(title, msg):
    w=WindowsBalloonTip(title, msg)

Should have an example like

if __name__ == '__main__':
    balloon_tip('Demonstration', 'Here is a balloon tip')

Also I can't do this more than once or it gives an error:

In [4]: balloon_tip('title', 'message')
------------------------------------------------------------
Traceback (most recent call last):
  File "<ipython console>", line 1, in <module>
  File "balloontip.py", line 55, in balloon_tip
    w=WindowsBalloonTip(title, msg)
  File "balloontip.py", line 26, in __init__
    classAtom = RegisterClass(wc)
error: (1410, 'RegisterClass', 'Class already exists.')

I PEPped this up a bit and fixed the "no 2nd notification" issue that @endolith reported. It still has one issue, which is that only one notification at a time can display, so if a 2nd notification is attempted before the 1st has finished, the 2nd is ignored. https://gist.github.com/brousch/6523559

Hey thanks for this gist! I used it in my backup script! https://github.com/vijayparsi/pyBackup

@brousch: dead link?

For anyone who needs a fix to @endolith's problem, after line 42 insert this code:

UnregisterClass(classAtom, hinst)

Bonjour
Merci c'est impeccable.

Hi,
Thank you, It's wonderful

Thank you @asm95!!

How to increase the display time of the balloon? It fades away after few seconds even if the script is running.

For those willing to change the time of the notification:
Go to line 41 and change time.sleep(__) to whatever number of seconds you want.

Can anyone please tell me how to add a click bind to this notification. I want to open a website or do some task on the click and I am not able to bind it in the message map. Please help!

Never mind guys. Found it! https://github.com/jithurjacob/Windows-10-Toast-Notifications/pull/38

How do I get a notification from the site I need?
