We can always call notify-send as a subprocess, e.g like that:

#!/usr/bin/env python

#-*- coding: utf-8 -*-



import subprocess



def sendmessage(message):

    subprocess.Popen(['notify-send', message])

    return

Alternatively we could also install python-notify2 or python3-notify2 and call the notification through that:

import notify2



def sendmessage(title, message):

    notify2.init("Test")

    notice = notify2.Notification(title, message)

    notice.show()

    return
