Isn't it possible to tell, where to find *.jar, so everyone interested, can study it with JPython? Please, take a closer look to JPython: http://www.JPython.org You will be able to use Java-classes from within JPython, so you can embed ready to use classes in your Pythoncode. I'm working in this way using a class-library in teaching informatics at secondary II level (my school is working with iMacs, Kirby (;-) You may take a look at this: http://region.hagen.de/OOP/ "JPython und das Java-Paket (hier ist nur SuM.jar nötig) können sofort eingesetzt werden. Material aus einem laufenden 11er Kurs (enthält SuM.jar und Hilfen für die Arbeit mit JPython)." This means: you'll get a ready to use packet and you get some material for to use it in the classroom. The curriculum is based on the idea on objectoriented modeling including programming -- there are other implementations of the really small class-library in pascal, oberon, etc. the course-material -- not depending on a special programming-language -- is published in german: @BOOK{Czischke1999, PUBLISHER = {DruckVerlag Kettler GmbH}, YEAR = 1999, EDITOR = {{Landesinstitut f{\"u}r Schule und Weiterbildung}}, ADDRESS = {B{\"o}nen}, ANNOTE = {ISBN 3-8165-4165-8}, TITLE = {Von Stiften und M{\"a}usen}, AUTHOR = {J{\"u}rgen Czischke and Georg Dick and Horst Hildebrecht and Ludger Humbert and Werner Ueding and Klaus Wallos} } You may take a look L.
