[PYTHON] Change the ID with a new user

[Joao:]

A simple code ( very simple ) to change the actual ID, to the next, when a new user enter, here's the code:

Code:

 """
CHANGING ACTUAL ID """
ID_Actual = 0
while 1:
    User_Actual = input('Type the username:  ')
    User_ID_Actual = ID_Actual
    print('USER: {}'.format(User_Actual))
    print('ID: {}'.format(User_ID_Actual))
    ID_Actual = User_ID_Actual + 1
    continue


Aint THAT thing, but it can be usefull

Great, for advanced login system, would be nice to add the time module, and use it before the ID changes.

Code:

import time
time.sleep(1)

And if I add a name that already exists ? Is there a way to refuse the user ?

You could use a var with the registered users

Code:

users = []

and refuse a connection with a username that is registered

Code:

newuser = input("Type a new username:  ')
if newuser in users:
  print('User already exists !')
  break ( if you are using a while loop)
