显示文件列表中的图片

Question

我想在目录中显示files.gif列表中的图片，图片应该每3秒更改一次。我确实尝试了不同的解决方案，但要么只显示第一张照片或没有。

TIA

    from  tkinter import *
import os
path = os.getcwd()
arr = []
for files in next(os.walk('/home/vimart/Python/img/'))[2]:
        arr.append('/home/vimart/Python/img' + "/" + files)
canvas_width = 300
canvas_height =300

master = Tk()

canvas = Canvas(master,
           width=canvas_width,
           height=canvas_height)
canvas.pack()

def display():
        canvas.create_image(20,20, anchor=NW, image=canvas.img)


def get_picture():
        for  picture in arr:
                canvas.img = PhotoImage(picture)
                master.after(3000, display)
get_picture()

mainloop()

我认为它不需要描述。

import tkinter as tk
from PIL import ImageTk
import os

# --- functions ---

def get_filenames(path):
    result = []

    #for one_file in os.listdir(path):
    for one_file in next(os.walk(path))[2]:
        if one_file.lower().endswith('.gif'): # sugessted by Nae
            result.append(path + one_file)

    return result

def display():
    global current_index

    picture = arr[current_index]
    canvas.img = ImageTk.PhotoImage(file=picture)
    canvas.create_image(20,20, anchor='nw', image=canvas.img)

    current_index = (current_index + 1) % len(arr)

    master.after(3000, display)

# --- main ---

path = '/home/vimart/Python/img/'

arr = get_filenames(path)
current_index = 0

canvas_width  = 300
canvas_height = 300

master = tk.Tk()

canvas = tk.Canvas(master, width=canvas_width, height=canvas_height)
canvas.pack()

display()

master.mainloop()
