Don't understand cause of this AttributeError: '_Screen' object has no attribute 'setimage'

Question

我的代码是：

import time
import turtle
from turtle import *
from random import randint

#GUI options
screen = turtle.Screen()
screen.setup(1000,1000)
screen.setimage("eightLane.jpg")
title("RACING TURTLES")

出现的错误信息是：

Traceback (most recent call last):   File
"/Users/bradley/Desktop/SDD/coding term 1 year 11/8 lane
experementaiton.py", line 14, in <module>
    screen.setimage("eightLane.jpg") AttributeError: '_Screen' object has no attribute 'setimage'

任何建议都有帮助。

做你想做的事情需要一个相当复杂的解决方法（实际上有两个）因为它需要使用 tkinter 模块来完成它的一部分（因为那是 turtle-graphics 模块在内部使用来做它的图形），并且 turtle 中没有名为 setscreen() 的方法，正如您通过 AttributeError 发现的那样。

更复杂的是，tkinter 模块不支持 .jpg。格式图像，因此需要另一种解决方法来克服该限制，这需要还需要使用 PIL（Python 图像库）将图像转换为 tkinter 支持的格式。

from PIL import Image, ImageTk
from turtle import *
import turtle

# GUI options
screen = turtle.Screen()
screen.setup(1000, 1000)

pil_img = Image.open("eightLane.jpg")  # Use PIL to open .jpg image.
tk_img = ImageTk.PhotoImage(pil_img)  # Convert it into something tkinter can use.

canvas = turtle.getcanvas()  # Get the tkinter Canvas of this TurtleScreen.
# Create a Canvas image object holding the tkinter image.
img_obj_id = canvas.create_image(0, 0, image=tk_img, anchor='center')

title("RACING TURTLES")

input('press Enter')  # Pause before continuing.
