I receive following Traceback:

Traceback (most recent call last):
  File "tkinter_basic_frame.py", line 4, in <module>
    from Tkinter import Tk, Frame, BOTH

    raise ImportError, str(msg) + ', please install the python-tk package'
ImportError: No module named _tkinter, please install the python-tk package

This is the demoscript I'm trying to run:

#!/usr/bin/python

from Tkinter import Tk, Frame, BOTH


class Example(Frame):

    def __init__(self, parent):
        Frame.__init__(self, parent, background="white")   

        self.parent = parent

        self.initUI()

    def initUI(self):

        self.parent.title("Simple")
        self.pack(fill=BOTH, expand=1)


def main():

    root = Tk()
    root.geometry("250x150+300+300")
    app = Example(root)

From my knowledge Tkinter should be included in Python 2.7. Why do I receive the traceback? Doesn't ubuntu contain the standard-python-distribution?

This is solved. I had to install it manually in synaptic (got the hint in the meantime from another forum), see here:

Wikipedia says: "Tkinter is a Python binding to the Tk GUI toolkit. It is the standard Python interface to the Tk GUI toolkit1 and is Python's de facto standard GUI,2 and is included with the standard Windows and Mac OS X install of Python." - Not good, that it isn't included in Ubuntu as well.
