[Tkinter] update the content of Text widget

[atlass218]

hi
I try to update the content of Text widget by using this fonction:

def affichage_ddm_axe_loc35R_update ():

	with open('archives/ILS_35R/loc35R/releves_mesure_loc35R/ddm_axe_loc35R/ddm_axe_monitor1_loc35R.txt') as ddm_axe_monitor1, open('archives/ILS_35R/loc35R/releves_mesure_loc35R/ddm_axe_loc35R/ddm_axe_monitor2_loc35R.txt') as ddm_axe_monitor2:
		
		s_generalites_bottom_axe_loc35R= Scrollbar(generalites_bottom)
		T_generalites_bottom_axe_loc35R= Text(generalites_bottom,bg='powder blue',width=450,height=350,font=('arial',14,'bold'))
	  
		s_generalites_bottom_axe_loc35R.pack(side=RIGHT, fill=Y)
		T_generalites_bottom_axe_loc35R.pack(side=LEFT, fill=Y)
		s_generalites_bottom_axe_loc35R.config(command=T_generalites_bottom_axe_loc35R.yview)
		T_generalites_bottom_axe_loc35R.config(yscrollcommand=s_generalites_bottom_axe_loc35R.set)
		while True:
			line1 = ddm_axe_monitor1.readline()
			if len(line1) == 0:
				break
			line1 = line1.strip().split()
			line2 = ddm_axe_monitor2.readline()
			line2 = line2.strip().split()
			T_generalites_bottom_axe_loc35R.insert(END, f'{line1[0]:15}\t {line1[1]:10}\t\t {line2[1]:10}\n')
T_generalites_bottom_axe_loc35R.after(1000, update) 

the above python code is inspired from the following code :

def update():
    with open("htfl.txt","r") as f:
        data = f.read()
        T.insert(END,data)
    T.after(1000, update)

the update of the content of the Text was actually done but only once time and not in a continuous and multiple times
can you help me please
