Actually, I'm not at all interested in the calculus stuff, because FriCAS is
rather good there, but rather for things like matrices and polynomials.
I admit, I'd be extremely interested in using Sage from FriCAS (i.e., "the
other way round"), because I tried Python a fair bit meanwhile (I even used it
for teaching) and I find it awful.
The main problem to get started is to call python from lisp. I posted a
question on this topic a while ago in comp.lang.lisp, comp.lang.python, and
here, but I didn't get the "final" answer. It seems to be relatively easy to
do it text based, but I don't think that makes too much sense.
For the record, here is the thread:
http://groups.google.com/group/comp.lang.lisp/browse_thread/thread/36f57b7b281e5a94?fwc=2
The very last message links to text-based communication.
It seems to boil down to: does Sage need the python interpreter, or is it
possible to have Sage as a library?
