turtle.onscreenclick(draw_smiley)

Now, instead of drawing random smiley faces all over the
screen, the user can draw a smiley face wherever they click the
mouse; they can even draw a big smiley face out of little smiley
faces, as shown in Figure 7-7.

Figure 7-7: We’ve made our smiley program more interactive, drawing
wherever the user clicks.
