python 2.7 - no module named tkinter

Question

i am on mac os x 10.8, using the integrated python 2.7. i try to learn about tkinter with tutorials like this for python 2.7 (explicitly not 3) they propose the following code:

from tkinter import *
import tkinter.messagebox

however, this brings up the error:

ImportError: No module named tkinter

using import.Tkinter with a capital t seems to work, but further commands like

import Tkinter.messagebox

don't (neither does tkinter.messagebox). I've had this problem with lots of tutorials. what's the thing with the capital / non-capital "T", and how do i get my python to work like it does in the tutorials? Thanks in advance!

In the second case is it No module named Tkinter or No module named messagebox ? — joaquin

Tkinter (capitalized) refers to versions <3.0.

tkinter (all lowecase) refers to versions ≥3.0.

In Tkinter (uppercase) you do not have messagebox. You can use Tkinter.Message or import tkMessageBox

This code is an example taken from this tutorial:

import Tkinter
import tkMessageBox

top = Tkinter.Tk()
def hello():
   tkMessageBox.showinfo("Say Hello", "Hello World")

B1 = Tkinter.Button(top, text = "Say Hello", command = hello)
B1.pack()

top.mainloop()

Your example code refers to a python installation >= py3.0. In Python 3.x the old good Tkinter has been renamed tkinter.

For python 2.7 it is Tkinter, however in 3.3.5 it is tkinter.
