Hi, I'm just becoming a teacher, but I've seen a collegue teaching processing and observed a few things that I don't like about it: - Processing comes with it's own IDE and the files you're writing are embedded in the real programming. The pupils don't have any change to get an overview of the "program". With a small python script OTOH, there's just the script and that's it. - Adding external (image) files to a processing program has puzzled the pubils and me too. You can't just download to your home folder and refer to a file with the filesystem path. Processing bundles your project to a java jar and so the downloaded files need to be added through the IDE. - Processing has some very ugly, global state and procedural idioms that I'd prefer not to teach to my students, like: textFont(letterGothic, 32); // sets the global text style text("word", 10, 50); // outputs text a more object oriented way would look something like style = new TextStyle(WHATEVER); style.print(WHATEVER); - Processing confronts the students with functions from day one, because all code must be embedded in one of two functions (setup and draw, IIRC).
