Hello I made a login system which stores usernames and password but it currently only holds one and every time I add a new one it deletes the old one how could I make so it continuously adds more to the list here is my code

def register_user():
   username_info = username.get()
   password_info = password.get()
 
   file = open("info.txt","w")
   file.write('username= '+username_info + "\n")
   file.write('password= '+password_info)
   file.close()

  • The "mode" argument should be "a" instead of "w". Other modes can be found in the Python documentation. – Michael Butscher Apr 02 '21 at 18:10
  • Change the ```"w"``` argument to ```"a"```. – Daweed Apr 02 '21 at 18:10

Open it in append mode with "a":

file = open("info.txt","a")

Other modes can be found in the Python docs.
