So I am basically trying to make a login system where the usernames and their passwords should be stored somewhere permanently. I tried importing my dictionary into a json file but that doesn’t work if the runtime is disconnected.

This is what I have coded:

import json
import getpass
with open('Users.json') as f:
Users = json.load(f)
with open('Completed.json') as f:
  Complete = json.load(f)
Q_Bank = {}
def clear():
  from IPython.display import clear_output
  clear_output()
print('     SIGN IN')
Username = input('Username: ')
if Username in Users.keys():
  Password = getpass.getpass(prompt='Enter your password: ')
  while Users[Username]['Password'] != Password:
    print('Wrong Password!')
    Password = getpass.getpass(prompt='Enter your password: ')
  else:
    clear()
    print('Welcome back ' + Username + '!')
else:
  print('Your username does not seem to exist. Please create a new one.')
  print('     LOG IN')
  Username = input('Username: ')
  Password = getpass.getpass(prompt='Enter your password: ')
  clear()
  print('Hello ' + Username + '!')
  User = {
      'Password' : Password
  }
  Users[Username] = User
with open('Users.json', 'w') as f:
    json.dump(Users, f)
