Error in basic button response program in Python 2.4 with the Tkinter module [SOLVED]


Today I started using Tkinter with Python 2.4, I have been reading tutorials, and running example programs and looking at the code used, but I have a small problem when I run code of my own.

Code:
from Tkinter import *
import tkMessageBox

class Application(Frame):

	def __init__( self, master):
		Frame.__init__( self, master )
		self.grid()
		self.create_widget()

		
def create_widget( self ):
	self.bttn = Button( self )
	self.bttn["text"] = "Click Me!"
	self.bttn["command"] = self.respond_to_click
	self.bttn.grid()

	
def respond_to_click( self ):
	tkMessageBox.showinfo( title = "Response", message="You clicked me!")

	
if __name__ == '__main__':

	root = Tk()
	root.title( "Button Response" )
	root.geometry( "200x100" )
	myApp = Application(root)
	root.mainloop()
I get an error of:
Code:
Traceback (most recent call last):
  File "/****/****/****/*****/test.pyw", line 28, in -toplevel-
    myApp = Application(root)
  File "/****/****/****/*****/test.pyw", line 9, in __init__
    self.create_widget()
AttributeError: Application instance has no attribute 'create_widget'
If I take out the "root" in "myApp = Application(root)" I get this error:
Code:
Traceback (most recent call last):
  File "/****/****/*****/*****/test.pyw", line 28, in -toplevel-
    myApp = Application()
TypeError: __init__() takes exactly 2 arguments (1 given)
Any ideas?

****Error messages edited taking out file path****

thanks to know ones help but my own the below code works.

Code:
from Tkinter import *
import tkMessageBox

class Application(Frame):

    def __init__( self, master):
	Frame.__init__( self, master )
	self.grid()
	self.create_widget()

		
    def create_widget( self ):
	self.bttn = Button( self )
	self.bttn["text"] = "Click Me!"
	self.bttn["command"] = self.respond_to_click
	self.bttn.grid()

	
    def respond_to_click( self ):
	tkMessageBox.showinfo( title = "Response", message="You clicked me!")

	
if __name__ == '__main__':

	root = Tk()
	root.title( "Button Response" )
	root.geometry( "200x100" )
	myApp = Application(root)
	root.mainloop()
apparently the idle-python2.4 IDE adds 2 tab spaces if you use
"class Application(Frame):"
and then
"def __init__( self, master):"
making everything 1 tab to far over, causing everything to screw up
