No, I didn’t know that. I thought selecting it in settings would be enough.
So now I can select one of the examples. Thanks for the help.

I have to modify my own script that I want to use. On previous systems I didn’t have to do that. The script doesn’t have a UI, but just prints something. That used to work but with the new version it doesn’t. But I guess I will find out by looking at the example widgets.

I bought a new iPad mini and it updated to 15,1. But I can’t set a script for the Pythonista widget. I select a script from Examples/Widgets, but after clicking Done it forgets it. When I click the widget it comes up again with the configuration screen and the selected script is no longer there.

Is there something I can do, or us this a bug?

Here is another simple example that I used myself, but anonamized. It works when the message text is ASCII.

#!/usr/bin/env python3
# Script to send an email. Runs with Python 3.6

# Import smtplib for the actual sending function
# Import the email modules we'll need
import smtplib
from email.message import EmailMessage

##### CONFIGURATION #####

SMTP_SERVER = 'smtp.example.com'
SMTP_PORT = 25
SMTP_LOGIN = None # user name if needed
SMTP_PASSWORD = 'secret'       # None if not needed

#########################

# Info for this message
# Adressee
name = 'adressee name'
email = 'adressee@example.com'
sender_name = 'Sender Name'
sender_email = 'sender@example.com'
subject = 'Test message'

message = '''Dear {name},

Thank you for your contribution to Python.

With kind regards,
{sender_name}
{sender_email}
