Hi Yoshiki, (I'm the Pippy author.)

(For the record, the workspace in > Etoys has been there from day one for this purpose.) This is a useful idea, thanks. At the moment, Pippy doesn't keep any variable/program state inbetween "Run!"s (each run is a new Python interpreter), so there is no way to do "Ans*2"-style calculations. It sounds like you want "Print!" to keep a single interpreter that reinterprets the source pane at each click. The first version of Pippy used a single Python interpreter that executed the program source code in this way, without losing state, but that makes it possible to write programs that will not run on a fresh interpreter later (as they refer to state that was generated as a result of code that no longer exists, or a previous run of the code), so I decided against keeping that. Oh! We could have an "example" in Pippy that, when run, gives you a Python interactive shell. That should work well; it gives you the mode you want (without requiring an extra button), and is useful in any case. I'll do that. I don't think Python's evaluations are useful as a calculator to a child, though. You would have to explain this: >>> 2+2 4 >>> 3/4 0 I would like to add a simple graphics screen to Pippy, but I don't intend it to get many more features past that -- I'd like to keep it at a simple introduction to input/output programming. > We have a real problem of shortage of man-power, so replacing > smaller activities that take more time to maintain and document > with more powerful ones is probably a good thing. Just a note that Reinier Heeres is a volunteer, so isn't pulling OLPC man-power away from any other projects.
