print("---------Welcome to Memory Card Hotel!-------")  _username = 'wryyy'  _password = 123  count = 0  while count <3:      username = input("username:")      password = int(input("password:"))      if _username == username and _password == password:          print("Logining now...Welcome {name}!".format(name = _username))          break      else:          print("Invalid username or password.")          count = count +1  else:      print("LOCKED ON,you have tried too many times.")
