When drawing things, Canvas sets up a window where our drawings will appear and returns a reference to it (saved in canvas). The mainloop function makes the canvas continue to display itself even after the user hits the X button on the program. Always include mainloop().

def main ():

• canvas = Canvas(800, 200, ‘Hello Rect’)
• canvas.create_rectangle(20, 20, 100, 100, “blue”)
• canvas.mainloop()

def main ():

• canvas = Canvas(width, height, title)
• canvas.create_rectangle(upper left coordinate, lower right coordinate, color)
• canvas.mainloop()

Coordinate of the top left corner of the canvas is (0,0)

Coordinate of the top right corner of the canvas is (CANVAS_WIDTH, 0)

Coordinate of the bottom left corner of the canvas is (0, CANVAS_HEIGHT)

Coordinate of the bottom right corner of the canvas is (CANVAS_WIDTH, CANVAS_HEIGHT)
