title: Tkinter messagebox without window?
body: <p>I want to show an info window in my python script running on ubuntu. I'm using the following code:</p>
  
  <pre><code>import tkMessageBox
  tkMessageBox.showinfo("Say Hello", "Hello World")
  </code></pre>
  
  <p>This works, but there's an empty window displayed, with the message box on top. How can I get rid of the window and just centre the message box on the screen (window manager is gnome 2)?</p>
  
  <p>This is just to display some info from a command line script (a password which is why I don't want to just echo it to the console).</p>
