This problem seems to be solved now using the approach described in this post:

• First uninstall Python 3.4.2 : pyenv uninstall 3.4.2, then
• Run sudo apt-get install tk-dev

Solution 2:

For MacOS you can try installing tcl-tk via homebrew and then activating the env. vars. mentioned in its caveats section, as detailed in this answer.

Change your code to:

import tkinter

Documentation link:

Most of the time, tkinter is all you really need, but a number of additional modules are available as well. The Tk interface is located in a binary module named _tkinter. This module contains the low-level interface to Tk, and should never be used directly by application programmers. It is usually a shared library (or DLL), but might in some cases be statically linked with the Python interpreter.
