Tools  edit

critlib's Typcl
an extension to use Tcl *from* Python. It doesn't really require CriTcl and could have been done in standard C.
Elmer
Elmer allows developers to write code in Python and execute it in Tcl. The resulting Tcl interface to the Python code generated by Elmer is transparent to the Tcl user... Python calls appear as Tcl calls ( "foo( 1, "a" )" in Python appears as "foo 1 a" in Tcl, for example) and Python and Tcl data types are automatically mapped (Tcl lists are converted to Python lists, Python dictionaries are returned as Tcl associative arrays, etc.). Elmer also supports Python's "freeze" module, allowing a Python developer to deliver a single library consisting of several Python files "frozen" in to the Tcl application... no need to set PYTHONPATH or have Python source files accompanying the Tcl application.
libtclpy
a Tcl extension to call Python from inside Tcl. The intention is to take the good parts of Elmer and tclpython and combine them to let you get going as fast as possible.

Description  edit

Python includes a standard facility for object-oriented programming.

Tcl is bundled into Python in order to make Tk available as the Python module, Tkinter. Beginning at version v1.5.2, includes IDLE, an integrated development environment for Python that requires Tkinter. Python 2.4 not only supports Tk on Unix, but Tk on Windows and Macintosh platforms as well.

An example of converting a Tcl list to a Python tuple:
#! /bin/env python

import Tkinter
tcl = Tkinter.Tcl()
result = tcl.call('lrange' ,'''one {two and} three''' ,0 ,'end')

To evaluate a Tcl script:
#! /bin/env python

import Tkinter
tcl = Tkinter.Tcl()
result = tcl.eval('some Tcl script here')

ActiveState provides Active Python binary downloads for Linux, Solaris and Windows.

Python, Enthought Edition, now Enthought Canopy, provides Python+packages bundle.

Misc  edit

AMG: Does anyone have Tcl code to read Python pickle [2] data? Tcl pickle, heh. Maybe someday I might develop it, if no one else has already done so.
