I haven't tried all the operations, but so far I have been able to use it without any problems.
*iPad OS 13.2.3 on iPad Air 3rd(10.5” display)

After updating to iPadOS on iPad Air 3rd, I started Pythonista and tried to run an existing program.

Thank you for your reply.
I was relieved to use it on iPadOS.
I will upgrade to iPadOS.

I'm going to update the iPad operating system from iOS13 to iPadOS13.
Is Pythonista available for iPadOS13?
If you actually use Pythonista on iPadOS, please let me know if there are any problems.

Thank you for your early comment.
I am going to use it as an example.
However, I was expecting only to place a radiobutton and set properties from the AddView screen.
I think it is inefficient to write a lot of code even though it has ui functionality.

Isn't it possible to place a radiobutton in .pyui?
Please let me know if you know how to place radiobutton.

Thank you for the information of SageMathCell.
I think it will be a useful environment to try out my own program.
The information that will be helpful in the future is very helpful.

I heard CoreML for the first time, but I wanted to do machine learning in the future, so it was a very useful information to me. Thank you very much.
But to use CoreML, my current skills are lacking, so I would like to study in the future.

Thank you for your reply.
The linked <recognition.py> seems a bit different from what I want to do.
What I want to do, for example, is that multiple cards arranged in a table recognize where and what cards are.

I wanted to recognize images using template matching (OpenCV matchTemplate, etc).
