from tkinter import *

With my python2, it works to replace the import by

from Tkinter import *
import ttk

 In Python 3, the module's named tkinter instead of Tkinter. You should
 
 be able to do the exact same import but with the lower-case name, or
 
 if you need to support both:
 
 
 
 try:
 
 import tkinter as tk
 
 except ImportError:
 
 import Tkinter as tk
 
This seems a very nice approach, but can you tell me how I should change the 
import-section as a whole; I tried it like here below (but that's certainly not 
the right way):


try:
import tkinter as tk
except ImportError:
import Tkinter as tk
from tk import *
import ttk

Regardless of your other fixes,  you should rename the bogus file:

/home/jean/tkinter.py

You very seldom want to have files that can shadow system modules.

  From your original post I only changed the she-bang line
  from python to python3 

#!/usr/bin/env python3

  and the import lines remained 
  as you originally posted 
  which are appropriate for python3  

from tkinter import *
from tkinter import ttk

  The traceback above shows an import statement
  that is different from the one you originally posted 
  which would be ok in python2 but not python3  

import Tkinter as tk

Thank you Dave, this made it work under python3 too. I also had to remove 
tkinter.pyc

I'm trying to go through a tutorial on tkinter which has the code below as an 
example. The only thing I see when running it is a little popup with Click 
mouse here to quit which works as expected but always shows the following 
error-message.
However the main window which should let you enter the numbers is not shown.

This is the quit error message:

from tkinter import ttk

def calculate(*args):

except ValueError:

root = Tk()
root.title(Feet to Meters)

Thanks for supplying the complete traceback.  But you should also

Since it failed on the second import, none of the rest of the code 
matters. However, since you're not running it from a terminal window, 
it's conceivable that your ide is affecting the result.

  This seems to be left over from an earlier post
  where you were binding a mouse event to a tk label

  Did you create a  new  file ?

  If I copy/paste your code as posted
  into a new file named ftom.py
  and change the she-bang line
  as follows 

#!/usr/bin/env python3

  Then from the command line 

python3 ftom.py

  Your code runs as expected
  using python 3.2.3

That is supposed to work.

In 8.4, they were in the Tile extension. I do not know if that will 
work. Better, probably, to upgrade.

Until you are able to import ttk, I believe you could remove the import 
and all 'ttk.' appearances, as I do not see anything ttk-specific.

I have two pythons installed on my system:
Python 2.7.3 and Python 3.2.3
When using python2 I get the errors mentioned above
When using python3 (I removed the shebang and started as python3 
feettometers.py) then I get these errors:

coolens@antec2:~$ python3 feet2meters.py 
Traceback (most recent call last):
  File feet2meters.py, line 1, in module
from tkinter import *
  File /home/coolens/tkinter.py, line 2, in module
import Tkinter as tk
ImportError: No module named Tkinter

I tried to fix this by installing
apt-get install python3-tk (python3-tk_3.2.3-1_amd64.deb)

but the error remains

What should I do now?

thanks in advance
jean

any idea what is going wrong?
