This should be quite easy to do. The best solution would be to first
write a small plug-in for Python and then create a style file with
py-eval and other markup you might need. All this (and much more)
is explained in detail in

Help -> Interfacing
Help -> Manual -> TeXmacs plugins
Help -> Manual -> TeXmacs as an interface

with several examples. It will probably take you a day or so to
read this stuff and get something working. This would be quite useful,
because several people have already been requesting for a Python plug-in.
So please read the documentation and ask us again if something
is not clear.

No, sessions are rather enriched shells for different systems,
and very useful when you want to do computer algebra,
numerical analysis, etc. I have the impression that
you are rather looking for something to make the text more dynamic.
TeXmacs also allows you to do that, although this possibility
has not been exploited much yet. So we would be very glad if
you want to do so :^)

Best wishes, Joris
