[Tkinter] Two text files in Text widget (python 3)

[Larz60+]

this code:

filename =('archives/loc1.txt')
fichier = open(filename, "r")
content_generalites= fichier.read()
fichier.close()
  
T_generalites.insert(END, content_generalites)

can be simplified to:

with open(filename, "r") as fichier:
    for line in fichire:
        T_generalites.insert(END, line.strip())

I don't see a second file, but just add a similar phrase for the second file

also, if you wish to intermingle data from both files, you can use:

with open(file1, 'r') as f1, open(file2, 'r') as f2:
    ...
