Python- Changing background color on Button click

Hi,

I am trying to write a python program which changes background color on click of button. However i am stuck up. Instead of changing the color currently it is creating a new frame every time.

please look at the code and let me know how to correct it

Code:

#!/usr/bin/env python

from Tkinter import *

class App(Frame):

    def __init__(self, master=None):
            Frame.__init__(self, master)
                self.pack()
                self.createWidgets()
                self.fm = Frame(root, width=300, height=200, bg="blue")
        self.fm.pack(side=TOP, expand=NO, fill=NONE)    
        #self.bgcolor()
    def createWidgets(self):
        self.MyButton = Button(self)
            self.MyButton["text"] = "Change Color"
            self.MyButton["fg"]   = "red"
        self.MyButton["command"] =  self.bgcolor
        self.MyButton.pack({"side": "left"})

    def bgcolor(self):    
        #self.fm.bg="red"
        self.fm = Frame(root, width=300, height=200, bg="red")
            self.fm.pack(side=TOP, expand=NO, fill=NONE)
    
    

root = Tk()
display = App(root)
display.mainloop()

tixNBFrame(n)						       Tix Built-In Commands						     tixNBFrame(n)

NAME

       tixNBFrame - Create and manipulate Tix NoteBook Frame widgets

SYNOPSIS

       tixNBFrame	    pathName	      ?options? 	  -background	 -borderWidth	-cursor        -disabledForeground	    -fore-
       ground	 -font		-height        -highlightColor -highlightThickness -relief	  -takeFocus -width

WIDGET-SPECIFIC OPTIONS
       [-backpagecolor backPageColor] Specifies the color for the extra space on the row of tabs which is not covered by any page tabs.   [-focus-
       color focusColor]  Specifies the color for the focus highlight.	[-inactivebackground inactiveBackground] Specifies the color for the inac-
       tive tabs (the active tab always have the same background color as the notebook).  [-tabpadx tabPadX] The  horizontal  padding  around  the
       text labels on the page tabs.  [-tabpady tabPadY] The vertical padding around the text labels on the page tabs.

DESCRIPTION

       The  NBFrame  widget  is  used privately inside the TixNoteBook(n) widget to display the page tabs. The application programmer should never
       create a NBFrame widget directly. The sole purpose of this maual page is to describe the options that can be used to configure the  appear-
       ance of the TixNoteBook widget.

       The  name  of  the NBFrame subwidget inside the TixNoteBook widget is called nbframe. It can be accessed using the subwidget command of the
       TixNoteBook widget or the -options switch. See below for an example.

EXAMPLE

       set nb [tixNoteBook .nb -options {
	   nbframe.BackPageColor gray60 }] $nb subwidget nbframe config -font fixed

       $nb add page1 -label "Page1" set page [$nb subwidget page1] button $page.b1 pack $page.b1

       pack $nb -expand yes -fill both
