Tkinter - use for loop to display multiple images-CodePudding

I am trying to display multiple images (as labels) to the window but only the last images is displayed

from tkinter import *
from PIL import ImageTk, Image

root = Tk()

f = open("data/itemIDsList.txt")
ids = []
for line in f:
    line = line.rstrip("\n")
    ids.append(line)
f.close()

for i in range(10):
    img = ImageTk.PhotoImage(Image.open(f"website/images/{ids[i]}.png"))
    Label(root, image=img, width=60, height=80).grid()

root.mainloop()

CodePudding user response：

Each time you reassign img in the loop, the data of the previous image gets destroyed and can no longer be displayed. To fix this, add the images to a list to store them permanently:

from tkinter import *
from PIL import ImageTk, Image

root = Tk()

f = open("data/itemIDsList.txt")
ids = []
for line in f:
    line = line.rstrip("\n")
    ids.append(line)
f.close()

imgs = []
for i in range(10):
    imgs.append(ImageTk.PhotoImage(Image.open(f"website/images/{ids[i]}.png")))
    Label(root, image=imgs[-1], width=60, height=80).grid()

root.mainloop()
