canvas = turtle.Screen()
canvas.bgcolor("white")
pen = turtle.Turtle()

# 画火柴人
pen.color("black")
pen.pensize(4)
pen.penup()
pen.goto(0, -100)
pen.pendown()
pen.circle(100)
pen.penup()
pen.goto(0, 0)
pen.pendown()
pen.right(90)
pen.forward(100)
pen.left(120)
pen.forward(80)
pen.penup()
pen.goto(0, 0)
pen.pendown()
pen.right(60)
pen.forward(80)
pen.penup()
pen.goto(0, -20)
pen.pendown()
pen.right(30)
pen.forward(40)
pen.penup()
pen.goto(0, -20)
pen.pendown()
pen.left(60)
pen.forward(40)

# 画爱心
pen.color("red")
pen.penup()
pen.goto(-100, 50)
pen.pendown()
pen.begin_fill()
pen.left(45)
pen.forward(70)
pen.right(135)
pen.circle(50, -180)
pen.right(135)
pen.forward(70)
pen.end_fill()

# 隐藏画笔
pen.hideturtle()

# 显示画布
canvas.mainloop()

运行以上代码，可以得到一个火柴人发射爱心的图形，如下所示：
