Update Image on Button Click

[the_muffin_man]

Hi,

I have asked this before and searched online. The answers i am getting are just far beyond where I am up to. My code may not be the most efficient nor may it be pretty but i know I am close and with a tweak here or there - anyway i am reaching out.

The premise is simple a hangman game that changes the image when a wrong letter is guessed. On the button click it has to update the label. Here is what i have so far.

import tkinter
from tkinter import messagebox

window = tkinter.Tk()
window.title("a title")
window.geometry("400x600")
window.configure(background = "green")

def checkans():
    if user_inp.get() in letters:
        tkinter.messagebox.showinfo("CONGRATULATIONS","You have guessed a correct letter")            
    else:
        tkinter.messagebox.showinfo("INCORRECT","That letter is not in the word")
        photo1Label.config(image = photo2,bd=0)

letters = ["h","o","m","e"]

photo1 = tkinter.PhotoImage(file = "hang1.png")
photo2 = tkinter.PhotoImage(file = "hang2.png")
photo3 = tkinter.PhotoImage(file = "hang3.png")
photo4 = tkinter.PhotoImage(file = "hang4.png")
photo1Label = tkinter.Label(window, image = photo1,bd=0)
photo1Label.image = photo1
photo1Label.place(x=100,y=210)

user_inp = tkinter.Entry(window,width=15)
user_inp.place(x=155,y=420)
    
check_guess = tkinter.Button(window,width=12,text="check if correct",fg="black",bg="gold",command=checkans)
check_guess.place(x=155,y=447)
    

window.mainloop()

I am figuring that if i can get the label config to update to something like this it might work but it doesnt seem to like it.
photo1Label.config(image = photo+str(counter),bd=0)

I have also tried having a helper variable. That also doesn't work.
bob = photo1+counter
photo1Label.config(image = bob,bd=0)

Been tearing my hair out.
Thanks in advance for reading and supporting

This works for me. Check the comments in the code

import tkinter
from tkinter import messagebox
 
window = tkinter.Tk()
window.title("a title")
window.geometry("400x600")
window.configure(background = "green")

# Index needs to be 1 for next image
index = 1

photo1 = tkinter.PhotoImage(file = "hang1.png")
photo2 = tkinter.PhotoImage(file = "hang2.png")
photo3 = tkinter.PhotoImage(file = "hang3.png")
photo4 = tkinter.PhotoImage(file = "hang4.png")

# Put all photos in a list
photos = [photo1, photo2, photo3, photo4]

def checkans():
    # Called global to use in function / Could have passed as args
    global photos, index
    
    if user_inp.get() in letters:
        tkinter.messagebox.showinfo("CONGRATULATIONS","You have guessed a correct letter")            
    else:
        tkinter.messagebox.showinfo("INCORRECT","That letter is not in the word")
        photo1Label.config(image = photos[index],bd=0)
    user_inp.delete(0, 'end')
    
    # If we get to the end of list reset
    if index >= len(photos):
        index = 0
    
    # Increase index for next photo
    index += 1
 
letters = ["h","o","m","e"]
 


photo1Label = tkinter.Label(window, image = photo1,bd=0)
photo1Label.image = photo1
photo1Label.place(x=100,y=210)
 
user_inp = tkinter.Entry(window,width=15)
user_inp.place(x=155,y=420)
     
check_guess = tkinter.Button(window,width=12,text="check if correct",fg="black",bg="gold",command=checkans)
check_guess.place(x=155,y=447)
     
 
window.mainloop()
