One interesting trick is to use json. From python, serialize all the outputs into one single json string. In matlab, convert the json string back to json.

That is a very interesting idea!Is there a reason to pass from python a json string and not direct make a json file?

Yes, you can do it with a json file as well. But then you need to write and read the file. Also if you write to a file, it doesn't need to be json.
