Answer 1

With a little experimentation I discovered you can do something like this to create a tcl interpreter, register a python command, and call it from Tcl:

import Tkinter

# create the tcl interpreter
tcl = Tkinter.Tcl()

# define a python function
def pycommand(*args):
    print "pycommand args:", ", ".join(args)

# register it as a tcl command:
tcl_command_name = "pycommand"
python_function = pycommand
cmd = tcl.createcommand(tcl_command_name, python_function)

# call it, and print the results:
result = tcl.eval("pycommand one two three")
print "tcl result:", result

When I run the above code I get:

$ python2.5 /tmp/example.py
pycommand args: one, two, three
tcl result: None
