PIL 和 tkinter 错误：TypeError：预期的 str、字节或 os.PathLike object，未列出

Question

I have this code, and the problem is I can't open the images. I did a random election to open a random image. Thanks!

Code:

import tkinter as tk
from tkinter import *
import random
from PIL import Image
window=Tk()
window.geometry('500x550')
window.resizable(False, False)
f=tk.Frame()
f.config(bg='blue', height='500', width='500')
f.pack()
cat=tk.Button(window, text='Cat')
cat.config()
cat.pack(fill=X)
dog=tk.Button(window, text='Dog')
dog.config()
dog.pack(fill=X)
images=['cat1.jpg', 'cat2.jpg', 'cat3.jpg', 'cube1.jpg', 'cube2.jpg', 'cube3.jpg']
imgimport = open(random.sample(images, 1))
img = PIL.Image.open(imgimport)
img.show()

Answer 1

random.sample() returns a particular length list of items chosen from the sequence. So even random.sample(list, length=1) returns a list, not the item. You can use random.sample()[0] as @Axe also said.

Answer 2

random.sample is used to generate a list. If you only want to get one,Why don't you just use random.choice(images) ,it will return a random string from list images .

You used Image.open in the end,so there is no necessary to use open .

And your code in the last can be reduced to

images=['cat1.jpg', 'cat2.jpg', 'cat3.jpg', 'cube1.jpg', 'cube2.jpg', 'cube3.jpg']
img = Image.open(random.choice(images))
img.show()
