我遇到了一个大问题，我真的不知道我写的这段代码有什么问题，它肯定与我为输入文件设置的输入有关，但我在墙上，我真的不知道不知道如何进行

我收到输入的名称错误，但这就是本书向我展示如何设置第一个存款的方式。输入文件位于主程序下方。

我的问题是，有谁知道我主要列出的输入有什么问题？它们似乎是正确的，但我不断收到 NameError: ABC123 is not defined for each change I try out。

class BankAccount:
    def __init__(self, getbankaccount, inputAmount=0):
        self.__balance = inputAmount
        self.__numDeposits = 0
        self.__numWithdrawals = 0
        self.__totalDeposits = 0
        self.__totalWithdrawals = 0
        self.__getbankaccount=getbankaccount

    def getBalance(self):
        return self.__balance

    def getNumDeposits(self):
        return self.__numDeposits

        self.__numDeposits = self.__numDeposits + 1
        self.__totalDeposits = self.__totalDeposits + amount
        return self.__balance

    def Withdrawal(self,amount):
        if (self.__balance >= amount):
            self.__balance = self.__balance - amount
            self.__numWithdrawals = self.__numWithdrawals + 1
            self.__totalWithdrawals = self.__totalWithdrawals + amount

当面对这样的事情时，尝试以交互方式调用 python 并进行一些实验：

$ python
Python 2.7.3 (default, Mar 12 2013, 16:26:07) 
[GCC 4.2.1 20070831 patched [FreeBSD]] on freebsd9
Type "help", "copyright", "credits" or "license" for more information.
>>> input()
11
11
>>> input()
ABC123
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1, in <module>
NameError: name 'ABC123' is not defined

好了，第一个问题被复制了。

大概你想要类似的东西raw_input()（或python 3.x，input现在就是这样）。

在不评论其他所有内容的情况下，我只在此处注意您的调度循环还检查类型“D”、“W”、“B”和“T”，但不检查“11”、“ABC123”等. 大概您想先设置帐户列表，然后再处理字母编码的交易。
