Python精灵模块的fill在封闭图形内填充颜色指令

from sprites import Sprite

turtle = Sprite('res/bug.png')
screen = turtle.getscreen()
screen.onmousemove(lambda x,y:screen.title(str(x)+"," + str(y)))

r = 200
turtle.pendown()
for i in range(4):
    turtle.fd(r)
    turtle.left(90)
turtle.penup()

turtle.goto(100,100)
turtle.fd(50)
turtle.left(90)
turtle.pendown()
turtle.circle(50)
turtle.penup()
turtle.wait(1)
turtle.ht()
turtle.fillcolor('pink') # 设定填充颜色
turtle.fill(100,10)      # 从x=100,y=10处开始填充pink色
screen.mainloop()
