Tkinter Create buttons from list with different image - python-3.x

Question

I want to create button from a list and I want them to have their own image.
I have tried this but only the last created button work.
liste_boutton = ['3DS','DS','GB']
for num,button_name in enumerate(liste_boutton):
button = Button(type_frame)
button['bg'] = "grey72"
photo = PhotoImage(file=".\dbinb\img\\{}.png".format(button_name))
button.config(image=photo, width="180", height="50")
button.grid(row=num, column=0, pady=5, padx=8)

Answer 1

Only your last button has an image as it is the only one that has reference in the global scope, or in any scope for that matter in your specific case. As is, you have only one referable button and image objects, namely button and photo.
Short answer would be:
photo = list()
for...
photo.append(PhotoImage(file=".\dbinb\img\\{}.png".format(button_name)))
But this would still have bad practice written all over it.

Answer 2

Your code appears okay, but you are need to keep a reference of the image effbot and also I do believe PhotoImage can only read GIF and PGM/PPM images from files, so you need another library PIL seems to be a good choice. I used a couple images from a google search for the images, they were placed in the same directory as my .py file, so i changed the code a little bit. Also the button width and height can cut off parts of the image if not careful.
from Tkinter import *
from PIL import Image, ImageTk
type_frame = Tk()
liste_boutton = ['3DS','DS','GB']
for num,button_name in enumerate(liste_boutton):
button = Button(type_frame)
button['bg'] = "grey72"
# this example works, if .py and images in same directory
image = Image.open("{}.png".format(button_name))
image = image.resize((180, 100), Image.ANTIALIAS) # resize the image to ratio needed, but there are better ways
photo = ImageTk.PhotoImage(image) # to support png, etc image files
button.image = photo # save reference
button.config(image=photo, width="180", height="100")
# be sure to check the width and height of the images, so there is no cut off
button.grid(row=num, column=0, pady=5, padx=8)
mainloop()

With all your comments I was able to achieve what I expected !
Thank ! I'm new to programming so this will not necessarily be the best solution but it works
import tkinter as tk
root = tk.Tk()
frame1 = tk.Frame(root)
frame1.pack(side=tk.TOP, fill=tk.X)
liste_boutton = ['3DS','DS','GB']
button = list()
photo = list()
for num,button_name in enumerate(liste_boutton):
button.append(tk.Button(frame1))
photo.append(tk.PhotoImage(file=".\dbinb\img\\{}.png".format(button_name)))
button[-1].config(bg="grey72",image=photo[-1], width="180", height="50")
button[-1].grid(row=num,column=0)
root.mainloop()
