Simple python login system

I got bored so I made a version of my login page that uses replit database

import os
import time
from replit import db

def clear_screen():
    if os.name == 'nt':
        _ = os.system('cls')
    else:
        _ = os.system('clear')
      
logedin = False

print("Python Login Page")
print("")
print("WARNING: don't ever enter real login information into this repl")
print("")

time.sleep(7)

while logedin != True:
  clear_screen()
  print("(1) Sign Up")
  print("(2) Login")
  answer = input(">> ")
  if answer == "1":
    used = False
    clear_screen()
    print("Sign Up")
    print("")
    print("New username")
    newUsername = input(">> ")
    print("New password")
    newPassword = input(">> ")
    keys = db.keys()
    for i in keys:
      if newUsername == i:
        used = True
    if used == False:
      db[newUsername] = newPassword
      print("Data saved")
    else:
      print("Username already in use")
    time.sleep(2)
  
  elif answer =="2":
    real = False
    clear_screen()
    print("Log In")
    print("")
    print("Username")
    username = input(">> ")
    print("Password")
    password = input(">> ")
    keys = db.keys()
    for i in keys:
      if username == i:
        real = True

    if real == True:
      if db[username] == password:
        print("Login successful")
        logedin = True
      else:
        print("Login unsuccessful")
    else:
      print("Login unsuccessful")
    
    time.sleep(2)
  else:
    print("Invalid option")
    time.sleep(2)

Or, y’know, the much faster alternative:

clear_screen = lambda: print('\033c', end='', flush=True)

lol

BTW, the Database would reset for every user who used your Repl

Does replit db normally reset for each user?

Yes, as it temp forks the repl and all it’s tools (including db) when viewing cover page.

Does it happen for all databases hosted on replit or just replit db?

Just replit DB, properly configured databases won’t even work on the cover page.
