I figured it out:

(setq org-latex-custom-lang-environments
         '((python "pyconsole")))

And of course \usepackage{pythontex} somewhere.

This is really nice. Now the Org buffer behaves as before, but the
exported LaTeX has the python code appear as if it were run right there
in an interactive session. I set ":export code" so the Org results are
not shown in the PDF, and PythonTeX re-generates the results and puts
them inline!

  -k.
