Take advantage of Tk canvas tags.
def myprint(arg):
x = arg.x
y = arg.y
canvas.delete('text') # delete any can

When you bind a function to the canvas, it is expecting a function that
takes an argument (which is probably the object to which the binding is
bound).
So, you could just all
[code]
from Tkinter import *
root = Tk()
root.title('Simple Plot - Version 1')
canvas = Canvas(root, width=450, height=300, bg = 'white')
canvas.pack()
Button(root, text='Quit', command=root.quit).pack()
canvas.create_line(100,250,400,250, width=2)
canvas.create_line(100,250,100,50, w
