bonjour;
je suis entrain de finaliser un projet, et j'ai rencontre un problème concernant l'actualisation automatique (update) du contenu du widget tkinter Text . voci le code correspondant à la partie qui pose problème :
 ```python 
 from tkinter import *
 from tkinter.ttk import Notebook
 import tkinter.ttk as ttk
 import time
 
 #window
 root=Tk()
 root.geometry('450x350')
 root.title('test')
 
 #variables
 ent_releves1=StringVar()
 ent_releves2=StringVar()
 
 #Functions:
 def archiver():
 	
 	archive_monitoring={"date" : time.strftime('%d/%m/%y', time.localtime()),	
 				 "releves_mesure1": ent_releves1.get(),
 "releves_mesure2": ent_releves2.get(), 				 }	
 	
 	if (ent_releves1.get() !="" ) :	
 		mon_fichier1 = open("save/monitor1.txt", "r")
 		text1 = mon_fichier1.read()
 		mon_fichier1.close()						
 		textInsert1=str(archive_monitoring["date"])+"\t" +str(archive_monitoring["releves_mesure1"])+"\n"
 		fileW1 = open("save/monitor1.txt", "w")
 		fileW1.write(textInsert1 + text1)
 		fileW1.close()
 	
 	if (ent_releves2.get() !="" ) :	
 		mon_fichier2 = open("save/monitor2.txt", "r")
 		text2 = mon_fichier2.read()
 		mon_fichier2.close()						
 		textInsert2=str(archive_monitoring["date"])+"\t" +str(archive_monitoring["releves_mesure2"])+"\n"
 		fileW2 = open("save/monitor2.txt", "w")
 		fileW2.write(textInsert2 + text2)
 		fileW2.close()
 
 def affichage_update ():
 
 	with open('save/monitor1.txt',"r") as monitor1, open('save/monitor2.txt',"r") as monitor2:
 		
 		s= Scrollbar(releves)
 		T= Text(releves,bg='powder blue',width=450,height=350,font=('arial',14,'bold'),pady=25)
 	 
 		s.pack(side=RIGHT, fill=Y)
 		T.pack(side=LEFT, fill=Y)
 		s.config(command=T.yview)
 		T.config(yscrollcommand=s.set)
 		
 		while True:
 			line1 = monitor1.readline()
 			if len(line1) == 0:
 				break
 			line1 = line1.strip().split()
 			line2 = monitor2.readline()
 			line2 = line2.strip().split()
 			T.insert(END, f'{line1[0]:15}\t {line1[1]:10}\t\t {line2[1]:10}\n')
 	T.update_idletasks()
 			
 
 	T.after(500,affichage_update)
