Making a scrollbar follow the last line in a list

So I have this simple list and scroll bar combo and I have been trying to make it stay at the bottom of the scroll bar as the text is added so it looks like the scroll bar is just to look back over the previous text.

Like in a text-based game style thing?

Here is la code:
python Syntax (Toggle Plain Text) 
  1. from Tkinter import *
  2.  
  3. root = Tk()
  4. displayscrollbar = Scrollbar(root)
  5. scrollbar.pack( side = RIGHT, fill=Y )
  6.  
  7. display = Listbox(root, yscrollcommand = scrollbar.set )
  8. for line in range(100):
  9.    display.insert(END, "This is line number " + str(line))
  10. display.pack( side = LEFT, fill = BOTH )
  11. scrollbar.config( command = display.yview )
  12.  
  13. mainloop()

Add this line
display.see(display.size()) after
scrollbar.config( command = display.yview )

Sorry, Is there any chance you might know how to do it with a Text widget?

use: Text.see(Text.END) in the same place as last time

There are 10 types of people in the world, those who get this, those who don't, and those who thought this was binary.
