Mysteriously all the scripts I tried that did not work now do work even though I have not changed anything so thanks for all the suggestions

import logging
logging.warning('Watch out!') # will print a message to the console
logging.info('I told you so') # will not print anything

this produces no output to my pythonista console.
What is wrong

Thank you so much, I feel so stupid, but at least I can now get on.

I am starting to learn UI and have reached the following point in the documentation:

"Using the UI Designer
If you went through the example above, you might have thought that this is a lot of code to do very basic things. You can significantly reduce the amount of boilerplate code by using the included visual UI editor.
Start by creating a new ‘User Interface’ file in your library. "

Can someone tell me where I can find the visual UI editor, and where is 'your library' and how do I create a 'User Interface file'
Many thanks. Paul B
