Attaching to a Python Interpreter a la Tcl

[Jeff Epler]

Cameron Laird mentioned Tk's send working with Python; if you are writing your
app with Tkinter, here is some code to let you use tcl commands like
    send <appname> python <expression or statement>
for remote control.  You could build a more sophisticated front-end for this,
and you'll probably also want to add stuff like sending the text of an
exception as the result of the 'send' command.
