tkinter import error on ubuntu 16.4

I tried to run a code which use turtle to draw a tree. There is no problem with code because I ran it on Windows 10 successfully, but on Ubuntu, the following error was encountered:

mosharraf@mmh:~$ cd Desktop
mosharraf@mmh:~/Desktop$ python3 Tree.py
Traceback (most recent call last):
  File "Tree.py", line 6, in <module>
    import turtle 
  File "/usr/local/lib/python3.6/turtle.py", line 107, in <module>
    import tkinter as TK
  File "/usr/local/lib/python3.6/tkinter/__init__.py", line 36, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'
mosharraf@mmh:~/Desktop$

Then I tried to install tkinter but I failed.

mosharraf@mmh:~$ sudo apt-get install python3-tk
[sudo] password for mosharraf:

python3-tk is already the newest version (3.5.1-1).

mosharraf@mmh:~$

Afterwards, I checked for the tkinter in the directories and found it.

mosharraf@mmh:/usr/local/lib/python3.6$ cd tkinter
mosharraf@mmh:/usr/local/lib/python3.6/tkinter$ ls

tkinter is in the directories as you can see above, but I can't import it. I tried several ways like

import tkinter

import tkinter as tk

from tkinter import *

etc.

Note that I ran the code in python 2.7 and it ran successfully. I also ran the code on Windows 10, Python 3.6. But in Ubuntu, it's causing the problem.

At the bottom of your post you say:

Note that I ran the code in python 2.7 and it ran successfully.

When you import Tkinter from Python 2 you must say:

import Tkinter

When you import Tkinter from Python 3 you must say:

import tkinter

A snippet I use for Tkinter when I know that my script is going to be ran from multiple versions of Python is below:

import sys

py_version = int(sys.version[0])

# If the python version is lower than 3, use Python 2 import
if py_version < 3:
    import Tkinter

# Otherwise use Python 3 import 
else:
    import tkinter

IF THE ABOVE DID NOT FIX YOUR PROBLEM:

I see that in one of your error messages it says

python3-tk is already the newest version (3.5.1-1).

But the error message also says that your Python version is 3.6.

Try using: sudo apt-get install python3.6-tk
