I have tried yor code, but I received

for c in self.grid.living_cells():
AttributeError: 'MyScene' object has no attribute 'grid' 

@cvp You are right maybe. Obviously I need real application for such purposes, not today widget.

@cvp I’m not 100% sure, because i have tried a lot of notifiers, but if I remember well, only time delay notifier works when main app ( Pythonista) is closed.

I mean It would be great if Pythonista today widget can send push notifications.
If you look on my screenshot f.e., in case there is a change of number of courts.

And if it’s possible to send push notification about changes, it would be great.

Here is a screenshot of my widget - now it works almost perfect.

I have up-to-date information about free tennis courts.

Thank you for the answer.

Please, don't remove widgets.

I know they are limited and will modify my source in order to work.

Thanks.

Hi,
Is there a way to debug a today widget?

In Pythonista app widget works as I want, but as a today widget sometimes works good, sometimes bad.

I have Pythonista v3.2 , iPhone v13.3.1,
re works perfect.
