Mountain Lion Notification Center via Python

mlnotifications.py

import Foundation
import objc
import AppKit
import sys

NSUserNotification = objc.lookUpClass('NSUserNotification')
NSUserNotificationCenter = objc.lookUpClass('NSUserNotificationCenter')

def notify(title, subtitle, info_text, delay=0, sound=False, userInfo={}):
	notification = NSUserNotification.alloc().init()
	notification.setTitle_(title)
	notification.setSubtitle_(subtitle)
	notification.setInformativeText_(info_text)
	notification.setUserInfo_(userInfo)
	if sound:
		notification.setSoundName_("NSUserNotificationDefaultSoundName")
	notification.setDeliveryDate_(Foundation.NSDate.dateWithTimeInterval_sinceDate_(delay, Foundation.NSDate.date()))
	NSUserNotificationCenter.defaultUserNotificationCenter().scheduleNotification_(notification)


notify("Test message", "Subtitle", "This message should appear instantly, with a sound", sound=True)
sys.stdout.write("Notification sent...\n")

@MrBjorn I was able to make it work on 10.9.5 by making it a proper python script:

$ cat > ~/tmp/n
#!/usr/bin/python
{cut-paste above here}
{Control-D}
$ chmod a+x ~/tmp/n
$ ~/tmp/n

Worked right out of the gate!

@baliw Thanks this saved me a lot of time digging into OSX Docs to figure out the objects and call structure.

Is there a way to custom the icon showing in notification?
The message does not wrap but cut off if longer than the width, any workaround?

Icon is dependent on the script icon. Just found that out myself.

I am getting this error:

Should I install pyobjc?.

Getting following error on MAC OS 10.13 onwards: error: NSInvalidUnarchiveOperationException - Class 'OC_PythonDictionary' has a superclass that supports secure coding, but 'OC_PythonDictionary' overrides -initWithCoder: and does not override +supportsSecureCoding. The class must implement +supportsSecureCoding and return YES to verify that its implementation of -initWithCoder: is secure coding compliant.

Is it possible to set a callback? For example, when a button is pressed, open a URL
