Python tkinter change 'open' in the title bar

Question

I would like to change the part of the title bar that say's 'open' below in the tkinter window-- see the root.title("Old file selected first") below:

Here is part of my code:

import Tkinter as tk
import tkFileDialog

root = tk.Tk()
root.title("Old file selected first") # what i would like to appear instead of 'Open'
root.withdraw()
old_file = tkFileDialog.askopenfilename(filetypes=[('.csvfiles', '.csv')])

Answer 1

You don't even need the other tk main app running, unless you want to hide the tkinter default box that pops up.

import tkFileDialog

old_file = tkFileDialog.askopenfilename(filetypes=[('.csvfiles', '.csv')],
                                        title='Old file selected first')
