•      from Tkinter import *
• else:
•     from tkinter import *
• import os
• win = Tk()
• win.title("Tk Canvas")
• win.geometry('800x800')
• c1 = Canvas(win, width=200, height=100)
• c1.pack()
• c1.create_line(0, 100, 200, 0, fill="red", dash=(4, 4))
• c1.create_rectangle(50, 25, 150, 75, fill="blue")
• c2 = Canvas(win, width=200, height=100)
• c2.pack()
