Error "ImportError: No module named tkinter" in Python Programming

Hi,

I am trying to write a Python program. This program is supposed to make a bar with two buttons on it pop up.

However, I cannot get this to work. The error is: "ImportError: No module named tkinter"

Below is the script of my program.

If anyone know enough about Python to know what I'm doing wrong, help would be greatly appreciated!

Thanks!

from tkinter import *

class Application(Frame):

    def say_Yeh(self):

        print("Yeh! Your button just did something!")

    def createWidgets(self):

        self.QUITBUTTON = Button(self)

        self.QUITBUTTON["text"] = "QUIT BUTTON"

        self.QUITBUTTON["fg"]   = "red"

        self.QUITBUTTON["command"] = self.quit

        self.QUITBUTTON.pack({"side": "left"})

        self.do_something = Button(self)

        self.do_something["text"] = "CLICK TO DO SOMETHING BUTTON",

        self.do_something["command"] = self.say_Yeh

        self.do_something.pack({"side": "left"})

    def _init_(self, master=None):

        Frame._init_(self, master)

        self.pack()

        self.createWidgets()

root = Tk()

app = Application(master=root)

app.mainloop()

root.destroy()
