Hiho,
One week ago I came across the nice `Try Ruby!`_ demonstration which
features an ajax based ruby console and a 20 minutes ruby tutorial.
I really liked that application and so I started to port that to
python.
Since I got a bit confused by the very complex javascript code I wrote
a

mply binds the name to
the first one, which is a very bad thing! So if you can find anything
related to this in the source, send me an email.
Oh, right, and in case you have no clue what I'm talking about, I'm
trying to replicate an interactive session online. My Try Python is a

Cool. I think its really a good thing. Could come in handy when one is
on a strange Windows machine with no Python installed, or when using a
PDA that doesn't have Python etc.

After spending time I should have been sleeping working on it, the try

anything real.

I'm afraid that I've spoiled the "try_python" working by means of
