Apparently Alice 1.0 supported Python, see
http://www.alice.org/bvw02fall/scripting/scripting.html
A source for Alice 1.0 is listed in Wiki but I don't know how up to date it is.
Alice 2.0 doesn't, from what I can tell, but does support something pretty close, see
http://www.westga.edu/~drocco/alice/scripting.html
This is already beyond my understanding of Python/Jython but might give you a start. Have fun blazing trails. (If you really didn't understand the reference, a "blaze" is a mark made on something, usually a tree, to show where a trail is for future travelers. The trail blazer has a challenge, since no one has gone before him to figure out how to get where he wants to go.)

Added Note: I did try the hello_network world on the second web site and it seems to work - at least I got the same message when I ran Alice and also accessed the URL directly from IE.
