关于两段turtle代码拼接失败的问题，如何解决？

Question

两段代码单独运行时不会报错，拼接就运行不了怎么回事

用代码块功能插入代码

#第一段
from PIL import Image

im = Image.open("2(2).jpg")
x, y = im.size
print(x, y)
 
import turtle
canvasX = x
canvasY = y
turtle.setup(x*1.2,y*1.2,600,300) 

def D(x, y):
    return x - canvasX // 2, - y + canvasY // 2
turtle.screensize(canvasX,canvasY, "black")
turtle.penup()
turtle.goto(D(0,0))
turtle.pendown()
turtle.pensize(1)
turtle.speed(0)
turtle.colormode(255)
turtle.delay(0)
turtle.tracer(x,0)
turtle.hideturtle()

for y in range(im.size[1]):
    turtle.penup()
    turtle.goto(D(0,y))
    turtle.pendown()
    for x in range(im.size[0]):
        pix = im.getpixel((x, y))
        turtle.pencolor(pix) 
        turtle.forward(1)
#第二段
turtle.pensize(5)
turtle.tracer(False)
r,g,b=255,255,255
for i in range(3):
    r, g, b=255-30*(i),255-30*(i),255-30*(i)
    turtle.pencolor(r/255,g/255, b/255)
    turtle.circle(1+3*i,360)
    turtle.penup()
    turtle.goto(0,-3*i)
    turtle.pendown()

```，请勿粘贴截图

我的解答思路和尝试过的方法

调整过不少次，不知道问题在哪

我想要达到的结果

图片基础上绘制圆点

Answer 1

pix = im.getpixel((x, y))
        turtle.pencolor(pix) 
        turtle.forward(1)
这里的pix是带alpha通道的,所以pencolor(pix[:3])
turtle.pencolor(r/255,g/255, b/255) 这里要整除，即turtle.pencolor(r//255,g//255, b//255)
