About

Pippy allows the student to examine, execute, and modify simple Python programs. In addition it is possible to write Python statements to play sounds, calculate expressions, or make simple text based interactive games.

Learning with Pippy

Etoys and Turtle art provide easy introduction to programming. Pippy introduces a more traditional view of programming a computer, wherein the instructions are first written to a text file, and then executed with a “run” command.

In particular, it is instructive to play with the sounds:

  1. Get the list of sounds by executing the Getsoundlist program
  2. Copy the name of one of the sounds and replace the “digeridu” sound name in Playwave program.

Extending Pippy

If Pippy is used in parallel with the Write Activity, it is possible to develop larger programs. Copy the program that you develop in the Write Activity by selecting all (ctrl + a) and copying it to the clipboard (ctrl + c), then switch to the Pippy Activity, and paste (ctrl + v) it into the code window. If there are errors that you want to correct, you can make the changes in the code window, and immediately see the results of your changes. Then by copying the changed program back to the clipboard, you can paste it back into the Word Activity, and save the changes to the Journal.

Modifying Pippy

The student can add small programs, and have them show up in the left column of Pippy by adding files to /home/olpc/Activities/Pippy.activity/data. There is a large number of suggested examples of programs for Pippy at http://wiki.laptop.org/go/Pippy#Examples.
