ATM取款机python

以下是一个基于Python开发的ATM取款机模拟系统的示例代码：

class Card(object):
    def __init__(self, cardid, cardpasswd, cardmoney):
        self.cardid = cardid  # 信用卡号
        self.cardpasswd = cardpasswd  # 信用卡密码
        self.cardmoney = cardmoney  # 卡内余额
        self.cardlock = False  # 是否被锁定

class ATM(object):
    def __init__(self):
        self.card_list = []  # 存储所有的信用卡对象

    def register(self, cardid, cardpasswd, cardmoney):
        card = Card(cardid, cardpasswd, cardmoney)
        self.card_list.append(card)
        print("注册成功！")

    def login(self, cardid, cardpasswd):
        for card in self.card_list:
            if card.cardid == cardid and card.cardpasswd == cardpasswd:
                if card.cardlock:
                    print("该卡已被锁定，请联系银行解锁！")
                else:
                    self.menu(card)
                break
        else:
            print("卡号或密码错误！")

    def menu(self, card):
        while True:
            print("1. 存款")
            print("2. 取款")
            print("3. 查询余额")
            print("4. 退出")
            choice = input("请输入操作选项：")
            if choice == "1":
                self.deposit(card)
            elif choice == "2":
                self.withdraw(card)
            elif choice == "3":
                self.check_balance(card)
            elif choice == "4":
                print("退出成功！")
                break
            else:
                print("无效的选项，请重新输入！")

    def deposit(self, card):
        amount = float(input("请输入存款金额："))
        card.cardmoney += amount
        print("存款成功！")

    def withdraw(self, card):
        amount = float(input("请输入取款金额："))
        if amount > card.cardmoney:
            print("余额不足！")
        elif amount % 100 != 0:
            print("取款金额必须为整百元！")
        else:
            card.cardmoney -= amount
            print("取款成功！")

    def check_balance(self, card):
        print("当前余额为：", card.cardmoney)

# 示例代码的使用
atm = ATM()
atm.register("1234567890", "123456", 1000)
atm.login("1234567890", "123456")
