Question

我正在尝试找到一种方法来定义“ deposit”变量，以便根据输出的前一行得出不同的输出。

例如，如果代码的先前输出是：

Sorry, minimum balance must be maintained. Account is frozen

我希望以后的任何存款都不会影响余额，并打印：

Sorry, account frozen

这是我的代码：

class MinimumBalanceAccount:
    def __init__(self,account_number,holder_name,min_balance):
        self.account_number = account_number
        self.holder_name = holder_name
        self.balance = 0
        self.min_balance = 200

    def withdraw(self, amount):
        self.balance -= amount
        if self.balance < self.min_balance:
            print("Sorry, minimum balance must be maintained. Account is frozen") 
            self.balance += amount
        return self.balance

    def deposit(self, amount):
        self.balance += amount
        if self.balance - amount < self.min_balance and self.balance - amount != 0:
            print("Sorry, account frozen.")
            self.balance -= amount  
        return self.balance + amount

我希望输出为：

Account: FR646 Paul
Depositing 500
Withdrawing 180
Withdrawing 180
Sorry, minimum balance must be maintained. Account is frozen
Depositing 500
Sorry, account frozen.
Balance: 320

鉴于此，我目前看到的是：

Account: FR646 Paul
Depositing 500
Withdrawing 180
Withdrawing 180
Sorry, minimum balance must be maintained. Account is frozen
Depositing 500
Balance: 820

我认为您的两个函数都在一个类中。由于您未显示课程，因此我将其称为Account。请注意，self变量将始终是此类的实例。您可以向其添加任何字段。例如，您可以执行self.locked = True来表明该帐户已被锁定。确保还包括一种__init__()方法，用于将self.locked初始化为适当的值。
