voila je voudrait faire un block , que l'on puisse bouger mai je ne si pas pourquoi le block reste immobile.

import pygame
from pygame.locals import *    #import libraire

pygame.init()

window = pygame.display.set_mode((500, 500)) # affichage fenetre
pygame.display.flip()
maroon = (100,66,50) #variable
red = (157,0,0)

            
Block = pygame.draw.rect(window, (maroon), ((100,200),(75,150))) #block 1 
pygame.display.update() 

                          
Continue = 1
while Continue:
    for event in pygame.event.get():	#Attente des événements
        if event.type == QUIT:
            continuer = 0
        elif event.type == KEYDOWN:
            if event.key == K_DOWN:	#Si "flèche bas"

                Block = Block.move(50,3)
 		#Rafraichissement
pygame.display.flip()
