Calling tcl from python and viceversa

[Carlos P.]

Hi!
I want to call tcl from python and python from tcl. The big picture is
that I´m writing an application GUI with tcl/tk and application logic
with python, so at least I want to call python events from the tk GUI.
I have read about _tkinter and tkapp.call although I couldn´t find any
detailed documentation. And, anyway, that seems to work in one
direction (python->tcl) but I don´t know how to make it work in the
other (tcl->python).
Thank you,
Carlos
