Ok. Thanks for the explanation.

Ok. So when people write these scripts then Pythonista has to be up and running first and then we just pick from our list of scripts in the file manager, yes
?

I'm totally new at this. So the calculator example that comes with Pythonista...does that mean I can run it from anywhere on my iPad? How do I make it start up? I can make it run in Pythonista, of course, but what if I want to actually start using it since the iPad does not come with a calculator? Or am I completely misunderstanding what I can do with Pythonista? I don't understand how one takes a script and makes it run on the iPad without starting Pythonista first.
