如何使用python维护简单的借贷对账单

我正在使用python（oops）中的以下代码来维护贷项-借方对账单。Classdef_Cash.py文件具有程序的主结构，Cash_001.py文件具有贷项和借方代码。除了贷项和借方值没有定期更新之外，一切正常。有人能帮我吗？请参考这两个文件并运行Cash_001.py文件。”“”

Classdef_Cash_001.py

是第一个文件，

Cash_001.py

是第二个文件

class Cash:

       def __init__(self, DATE, VOUCHER, SPECIFICATION, INITIAL_AMOUNT, CREDIT,DEBIT, REMARKS, BALANCE):

请参考下面的代码。这正是我想要的一个统一的借贷余额表。无论何时有资金流入，借方都被强制为零，无论何时有支出，贷方都被强制为零。贷方和借方仅在输出的第一行保持零，这是从上个月。这类似于有输入时禁用输出，有输出时禁用输入的概念。请运行Cash_001.py文件

   #Classdef_Cash_001.py 
   class Cash:

   def __init__(self, DATE, VOUCHER, SPECIFICATION, INITIAL_AMOUNT, CREDIT,DEBIT,
   REMARKS, BALANCE):

        self.VOUCHER = VOUCHER
        self.SPECIFICATION = SPECIFICATION
        self.CREDIT = CREDIT
        self.DEBIT = DEBIT
        self.REMARKS = REMARKS
        self.BALANCE = INITIAL_AMOUNT

   def Spending(self,DATE,VOUCHER,SPECIFICATION,DEBIT,CREDIT,REMARKS):
        self.DATE = DATE
        self.VOUCHER = VOUCHER
        self.SPECIFICATION = SPECIFICATION
        self.REMARKS = REMARKS
        self.DEBIT = DEBIT
        self.CREDIT = 0
        self.BALANCE -= DEBIT

   def CashInflow(self,DATE,VOUCHER,SPECIFICATION,CREDIT,DEBIT,REMARKS):

我们应该猜测您得到了什么结果以及您期望得到什么结果吗？不相关，但您的设计在我看来是非常错误的-您正在覆盖实例属性，而很可能希望跟踪所有操作。您确实需要两个不同的类：一个表示离散操作（应该是不可变的），并跟踪这些操作。请使用所有相关信息编辑您的帖子-您得到了什么，以及您期望得到什么。贷方和借方值不能同时为零。对于花费的现金或进入帐户的现金，贷方应为非零或借方应为非零。输出如下。日期：2018年10月1日，凭证：000，规格：结转，贷方：0，借方：0，备注：余额，余额：2000日期：2018年10月1日，凭证：001，规格：油，贷方：0，借方：0，备注：JOHN，余额：2018年10月1日，凭证：001，SP规格：油，贷方：0，借方：0，备注：约翰，余额：1800预计：日期：2018年10月1日，凭证：001，规格：油，贷方：0，借方：200，备注：约翰，余额：1800
