python - Python Turtle Graphics with Geometry Propogation

Question

I am trying to make the window my turtle graphics run in have geometry propagation, but when I have the following code:

from tkinter import *
import turtle

tk=Tk()
tk.grid_propagate()
turtle.pd
turtle.forward(100)
turtle.mainloop()

I get two windows, one with geometry propagation and no graphics, and one with graphics and no propagation.

Any help is appreciated.
