[IAEP] Which Language?

The original question was about developing Activities for a classroom
assignment, with the idea that these Activities could be widely
distributed. With these two constraints Python is the winner by
default. If you need to write Activities for school you need good
documentation on how to use the API's, etc. We have that for Python,
the rest not so much. Also, they want to put their Activities on ASLO
and make them useable by as many people as possible. Python makes
that possible, other options not so much.
I don't agree with your performance comparison of Java and Python. If
I wrote Read Etexts in both languages my guess is that the Python
version would perform better and use less memory than the Java/Swing
version. That's because in the Python version Python is just used as
a glue language and the heavy lifting is done in GTK. In Java/Swing
ALL the work would be done in Java.
I have my own gripes about Python but since my own requirements are
similar to those Caryl was asking for Python is what I use.
