I tried your idea and it doesn't animate it. I made a for loop and told it 
to mover 1 pixel downward every .3 seconds for 25 times. It just waits till 
the for loop is completed and then displays the result of the loop ending. I 
also tried it without the for loop by writing each one of the steps out 
repetively and I had the same result. The only thing that has kind of got 
close to the visual is that I wrote a program that everytime the user 
clicked the button it moved down one pixel, but I want it to move 100 
pixels, one by one, with only one click from the user. Here's the code that 
I wrote:

from Tkinter import *
from time import sleep

class Main:

def __init__(self,master):
button = Button(master,text='button')
button.place(x=1,y=1)
y=3
for x in range(1,25):
sleep(.3)
button.place_forget()
button.place(x=1,y=y)
y+=2


root = Tk()
Main(root)
root.title('test')
root.mainloop()

Thanks for all the help so far.
