How can I listen to Windows 10 notifications in Python?

Question

My Python test script causes our product to raise Windows notifications ("Toasts"). How can my python script verify that the notifications are indeed raised?

I see it's possible to make a notification listener in C# using Windows.UI.Notifications.Management.UserNotificationListener (ref), And I see I can make my own notifications in Python using win10toast - but how do I listen to othe apps' notifications?

You can use pywinrt to access the bindings in python. A basic example would look something like this:

from winrt.windows.ui.notifications.management import UserNotificationListener, UserNotificationListenerAccessStatus
from winrt.windows.ui.notifications import NotificationKinds, KnownNotificationBindings

if not ApiInformation.is_type_present("Windows.UI.Notifications.Management.UserNotificationListener"):
    print("UserNotificationListener is not supported on this device.")
    exit()

listener = UserNotificationListener.get_current()
accessStatus = await listener.request_access_async()

if accessStatus != UserNotificationListenerAccessStatus.ALLOWED:
    print("Access to UserNotificationListener is not allowed.")
    exit()

def handler(listener, event):
    notification = listener.get_notification(event.user_notification_id)

    # get some app info if available
    if hasattr(notification, "app_info"):
        print("App Name: ", notification.app_info.display_info.display_name)

listener.add_notification_changed(handler)

I don't work on the same product anymore, so I can't verify the answer. It does sound like the right solution, so accepted, thanks! — Jonathan, Mar 23 '22 at 08:09

Searching python windows notification listener on google brings up only this ok-ish result but it is not complete.

Since i couldn't find any self contained example on how to do it, here is a fully working code:

from winrt.windows.ui.notifications.management import UserNotificationListener
from winrt.windows.ui.notifications import KnownNotificationBindings

def handler(asd, aasd):
    unotification = asd.get_notification(aasd.user_notification_id)
    # print(dir(unotification))
    if hasattr(unotification, "app_info"):
        print("App Name: ", unotification.app_info.display_info.display_name)
        text_sequence = unotification.notification.visual.get_binding(KnownNotificationBindings.get_toast_generic()).get_text_elements()

        it = iter(text_sequence)
        print("Notification title: ", it.current.text)
        while True:
            next(it, None)
            if it.has_current:
                print(it.current.text)
            else:
                break            
    else:
        pass

listener = UserNotificationListener.get_current()
listener.add_notification_changed(handler)

while True: pass
