这一个 atm 的 python 程序

以下是一个简单的 Python ATM 程序，它可以模拟 ATM 的基本功能，包括检查账户余额、取款、存款和余额查询等操作：

class ATM:
    def __init__(self, balance=0):
        self.balance = balance

    def check_balance(self):
        print("Your current balance is: ", self.balance)

    def withdraw(self, amount):
        if self.balance - amount < 0:
            print("Insufficient balance. Withdrawal failed.")
        else:
            print("Withdrawal successful. Please collect your cash.")
            self.balance -= amount

    def deposit(self, amount):
        self.balance += amount
        print("Deposit successful. Your current balance is: ", self.balance)


atm = ATM(5000)

while True:
    print("Welcome to the Python ATM!")
    print("1. Check balance")
    print("2. Withdraw cash")
    print("3. Deposit cash")
    print("4. Quit")
    option = input("Please select an option: ")

    if option == "1":
        atm.check_balance()
    elif option == "2":
        amount = int(input("Please enter the amount to withdraw: "))
        atm.withdraw(amount)
    elif option == "3":
        amount = int(input("Please enter the amount to deposit: "))
        atm.deposit(amount)
    elif option == "4":
        print("Thank you for using the Python ATM!")
        break
    else:
        print("Invalid option. Please try again.")

这是一个基本的 ATM 类，它包含了检查余额、取款、存款和退出等功能。在程序中，我们首先创建了一个 ATM 对象，并将其初始余额设置为 5000。然后，我们在一个 while 循环中显示了 ATM 的菜单，用户可以选择一个选项来执行不同的操作。当用户选择退出时，程序退出。
