In Ubuntu it is easy to install Pymacs because it is on the standard
repository.

The question is about passing values from python and elisp and the opposite
way.

# A function that receives a elisp variable name and returns it's value:
from pymacs import lisp
def tvar(n):
    return lisp[n].value()


AND IN ELISP:

(pymacs-load "pymacs_teste")

(setq PTEST "string")
(pymacs-teste-tvar "PTEST") ;; returns "string" Ok!

(setq PTEST (list 1 2 3))
(pymacs-teste-tvar "PTEST") ;; returns (lambda (&rest arguments)
(pymacs-apply (quote (pymacs-python . 4543)) arguments))

When python calls lisp[n].value() it returns a kind of wrapper which works
well inside python. But if I return it back to elisp, it doesn't work.

If I do instead
def tvar(n):
    return list( lisp[n].value() )

It works perfectly.

But I don't know what to do if PTEST contains a elisp symbol.
