#112208 — Tcl/Tk for Python 3.6.0a3 on Os X 10.9.5

Hello,

I am new to the programming world but I need to learn this program for a research class that I am taking. I have downloaded Python 3.6.0a3 on a Mac 10.9.5 and realized that I also need to download an Active Tcl for it. I can't find one for this version. Can someone please direct me to it? The most recent one I've been able to find is for Python 3.5.2

Thanks!

Valeria

Tcl/Tk is independent from Python; any version should work. For best 
results on the Mac, try the most recent ActiveTcl from here 
http://www.activestate.com/activetcl/downloads/thank-you?dl=http://downloads.activestate.com/ActiveTcl/releases/8.6.4.1/ActiveTcl8.6.4.1.299124-macosx10.5-i386-x86_64-threaded.dmg

To add to what Christian suggested: If you can't get something working
using an alpha build of Python (that's an unreleased development
version), download Python 3.5.2 instead. That's the current stable
release. Using alphas opens you up to new bugs and incompatibilities,
and generally isn't something I'd recommend for a new programmer. It's
only fools like me who use unreleased software :)

This page https://www.python.org/download/mac/tcltk/
does not yet mention 3.6.  So I would start with the recommendation for 
3.5.2: tcl/tk 8.5.18.

I believe Ned Deily hopes to switch to tcl/tk 8.6.x before 3.6.0 is 
released.  If 8.5.18 does not work, I would try 8.6.whatever.  But I 
don't believe the switch has been made yet.

Yes, sorry, I don't usually update that page for pre-releases.

The information you need is also included in the python.org OS X
installer Read Me file which is displayed during the installation
process.  (A copy of it is also preserved at "/Applications/Python
3.6/ReadMe.rtf".).  In the section "Update your version of Tcl/Tk to use
IDLE or other Tk applications":

"For the initial alpha releases of Python 3.6, the installer is linked
with Tcl/Tk 8.5; this will change prior to the beta releases of 3.6.0."

Let me also convey some insider information from the Tcl world: the 
upcoming 8.7 (I'll expect it next year) will have full Unicode support 
(>BMP). Because of compatibility issues with the C API, this will be 
done in the way that Tcl unicode strings are considered UTF-16 instead 
of UCS-2. So adapting Tkinter should be relatively easy in the end, if 
it passes UTF-8 strings, then there is zero change, if it passes 
Tcl_UniChar, then these must be convrted to UTF-16.

Ehh. Well, it's no worse than ECMAScript uses.

Python should already come with Tk <https://docs.python.org/3/library/tk.html>. Tcl is an entirely separate language from Python. While it is where Tk originated, you don’t need it to use Tk with Python.

This is very inaccurate.  From the first line of the second paragraph
at your link, "The tkinter package is a thin object-oriented layer on
top of Tcl/Tk."

Tk is very closely tied to Tcl (in fact a significant fraction of Tk
is implemented in Tcl), and a Tcl interpreter (of the exact same
version) is required to use Tk.  Python's tkinter package dynamically
links to libtcl and libtk to embed a Tcl interpreter, and all GUI
interactions are handled by Tcl calling Python callbacks.
