Tkinter : créer une liste

Bonjour,

je suis débutante et je me lance dans la programmation d'un jeu. Plusieurs images y sont en mouvement, seulement voilà ce que donne le programme :

 from tkinter import*
import os
from PIL import Image, ImageTk
 
def deplacement():
    global dx, dy
    if canvas.coords(W_image)[1]>400:
       canvas.coords(W_image,180,0)
    if canvas.coords(W_image1)[1]>400:
       canvas.coords(W_image1,180,0)
    if canvas.coords(W_image2)[1]>400:
       canvas.coords(W_image2,180,0)  
    if canvas.coords(W_image3)[1]>400:
       canvas.coords(W_image3,180,0)
    if canvas.coords(W_image4)[1]>400:
       canvas.coords(W_image4,180,0)
    if canvas.coords(W_image5)[1]>400:
       canvas.coords(W_image5,180,0)
    if canvas.coords(W_image6)[1]>400:
       canvas.coords(W_image6,300,0)
    if canvas.coords(W_image7)[1]>400:
       canvas.coords(W_image7,300,0)
    if canvas.coords(W_image8)[1]>400:
       canvas.coords(W_image8,300,0)
    if canvas.coords(W_image9)[1]>400:
       canvas.coords(W_image9,300,0)
    if canvas.coords(W_image10)[1]>400:
       canvas.coords(W_image10,300,0)
    if canvas.coords(W_image11)[1]>400:
       canvas.coords(W_image11,300,0)
    canvas.move(W_image,dx,dy)
    canvas.move(W_image1,dx,dy)
    canvas.move(W_image2,dx,dy)
    canvas.move(W_image3,dx,dy)
    canvas.move(W_image4,dx,dy)
    canvas.move(W_image5,dx,dy)
    canvas.move(W_image6,dx,dy)
    canvas.move(W_image7,dx,dy)
    canvas.move(W_image8,dx,dy) 
    canvas.move(W_image9,dx,dy)
    canvas.move(W_image10,dx,dy)
    canvas.move(W_image11,dx,dy)
    root.after(60,deplacement)

 
dx=0
dy=5

root = Tk() 

#Chemin pour les images
script_dir = os.path.dirname(__file__)
rel_path = "/images/"
abs_file_path = script_dir + rel_path

image = Image.open(abs_file_path+"baptiste.png")
photobaptiste = ImageTk.PhotoImage(image)

image = Image.open(abs_file_path+"clarys.png")
photoclarys = ImageTk.PhotoImage(image)

image = Image.open(abs_file_path+"anais.png")
photoanais = ImageTk.PhotoImage(image)

image = Image.open(abs_file_path+"allan.png")
photoallan = ImageTk.PhotoImage(image)

image = Image.open(abs_file_path+"arnold.png")
photoarnold = ImageTk.PhotoImage(image)

image = Image.open(abs_file_path+"thomas.png")
photothomas = ImageTk.PhotoImage(image)

image = Image.open(abs_file_path+"ayoub.png")
photoayoub = ImageTk.PhotoImage(image)

image = Image.open(abs_file_path+"caroline.png")
photocaroline = ImageTk.PhotoImage(image)

image = Image.open(abs_file_path+"deborah.png")
photodeborah = ImageTk.PhotoImage(image)

image = Image.open(abs_file_path+"louis.png")
photolouis = ImageTk.PhotoImage(image)

image = Image.open(abs_file_path+"paul.png")
photopaul = ImageTk.PhotoImage(image)

image = Image.open(abs_file_path+"nono.png")
photonono = ImageTk.PhotoImage(image)

canvas=Canvas(root, width=500, height=400, bg='white')
canvas.pack(padx=10,pady=10)

#On cree le Widget image dans le canvas:
#NW=Nord West, le coin haut guche de l'image sera positionne a (10,10):
W_image=canvas.create_image(180,0,anchor=NW,image=photoclarys)
W_image1=canvas.create_image(180,50,anchor=NW,image=photobaptiste)
W_image2=canvas.create_image(180,120,anchor=NW,image=photoanais)
W_image3=canvas.create_image(180,190,anchor=NW,image=photoallan)
W_image4=canvas.create_image(180,250,anchor=NW,image=photoarnold)
W_image5=canvas.create_image(180,330,anchor=NW,image=photothomas)
W_image6=canvas.create_image(300,0,anchor=NW,image=photoayoub)
W_image7=canvas.create_image(300,50,anchor=NW,image=photocaroline)
W_image8=canvas.create_image(300,120,anchor=NW,image=photodeborah)
W_image9=canvas.create_image(300,190,anchor=NW,image=photolouis)
W_image10=canvas.create_image(300,250,anchor=NW,image=photopaul)
W_image11=canvas.create_image(300,330,anchor=NW,image=photonono)

deplacement()
 
root.mainloop() 

Je suis bien consciente que ce n'est ni facile à lire ni esthétique avec autant de lignes, c'est pour cela que j'aimerai tout regrouper grâce à une liste, mais je ne comprend pas trop comment faire. Si quelqu'un veut bien m'aider, merci d'avance.
