Thank you for the comment.

Yes. But, Pippy can pretend that it is not about Python at first.
The user can type "3+4" into the top pane, and if there is a "Print!"
button, the user would see "7" in the lower pane. I could imagine to
have number and four basic arithmetic buttons on screen.

This is true. For example, I think there should be a way to stop a
long running execution (a la keyboard interrupt).

Gradual progression when a child is learning is something we think
about a lot. I tend to think that the progression as "removing
fences". The introductory version shows something simpler, but as the
child learns more, he will be able to access more. And, I have some
prejudice that to make the progression smoother, it would be nice if
the environment is kept the same, but make the kid realize that these
seemingly different interfaces are just facets are the same thing.
