python 3.x - Tkinter module not found on Ubuntu

Question

Python 2.7.1+ (r271:86832, Apr 11 2011, 18:05:24) 
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
>>> 

on the other hand...

Python 3.2 (r32:88445, Mar 25 2011, 19:28:28) 
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named Tkinter 

I checked synaptic, Tkinter is installed. Then I found this--

If it fails with "No module named _tkinter", your Python configuration needs to be modified to include this module (which is an extension module implemented in C). Do not edit Modules/Setup (it is out of date). You may have to install Tcl and Tk (when using RPM, install the -devel RPMs as well) and/or edit the setup.py script to point to the right locations where Tcl/Tk is installed. If you install Tcl/Tk in the default locations, simply rerunning "make" should build the _tkinter extension.

I am guessing that tkinter is still associated with the old python in my pc. How do I change that so python3 can use tkinter?

What worked for me in Ubuntu was actually just:

sudo apt-get install python3-tk

For python 3.6:

sudo apt-get install python3.6-tk

I didn't read anywhere, I simply tried it, as onteria_'s method didn't seem to work for me.
