不了解此AttributeError的原因：“ _ Screen”对象没有属性“ setimage”

Question

The code I have is:

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")

The error message that comes up is:

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'

Any advice is helpful.

Answer 1

To do what you want requires a fairly involved workaround (two of them actually) because it requires using the tkinter module to do part of it (because that's what the turtle -graphics module uses internally to do its graphics), and turtle doesn't have a method in it called setscreen() , as you've discovered via the AttributeError .

The complicate matters further, the tkinter module doesn't support .jpg . format images, so yet another workaround is needed to overcome that limitation, which requires needing to also use the PIL (Python Imaging Library) to convert the image into a format tkinter does support.

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.
