Question

到目前为止，我已经“制作”了一个ATM程序，它可以保存到一个文件中并且可以记住东西等等。现在我需要尝试制作它以便它可以有一个引脚保护系统，我该如何制作呢？我会把它放在我的代码中？我需要再次保存到文件吗？请帮忙

users = {}
userInput = 0
money = 0
with open("N:\ATM.txt") as f:
    for line in f:
       (key, val) = line.split()
       users[key] = val

print "Welcome to the ATM"

check = raw_input("Are you a new user?: ").lower()
if check == "yes":
   user= raw_input("Hi, new user, what is your name? ")
   users[user] = 0
else:

   user = raw_input("Please enter your name to log: ").lower()
   if user in users:
      print "Welcome Back" , user
      money = float(users[user])
while userInput != "d":
   with open("N:\ATM.txt") as f:
      userInput = raw_input("\n what would you like to do?\n\n     (1)Check balance\n     (2)Insert funds\n" +
    "     (3)Make a withdrawl\n     (4)Exit the ATM\n" ).lower()
   if userInput == "1":
      print "your balance is", "£" , money
   elif userInput == "2":
      mon = float(raw_input("Enter the amount of money you want to add "))
      money = money + mon
   elif userInput == "3":
      withdraw = float(raw_input("Enter the amount of money you want to withdraw"))
      money = money - withdraw
   elif userInput == "4":
      users[user] = money
      print "Bye, thank you for using the ATM"
      exit()
      with open("N:\ATM.txt", 'w') as f:
         for key, value in users.items():
            f.write('{} {}\n'.format(key, value))
