I have to write a program to process a file of many bank transactions. The data file we have to use with the program goes like this: The first line of the file indicates the number of bank accounts. If the first line is ‘x’ – then the next ‘x*2’ lines are pairs of data containing: • bank account number • current balance I have to create a bank account object and put them in a list. Following these lines are an unknown number of "sets" of data for transactions. Each transaction consists of: transaction type (W,D,T or B) account number(s) amount The sentinel value is a transaction type of "#". This is what my code looks like so far:

class BankAccount:
 def __init__(self, inputNum, inputAmount):
 self.__acctNum = inputNum
 self.__balance = inputAmount
 self.__numDeposits = 0
 self.__totalDeposits = 0
 self.__numWithdrawals = 0
 self.__totalWithdrawals = 0
 def getAcctNum(self):
 return self.__acctNum
 def getBalance(self):
 return self.__balance
 def getNumDeposits(self):
 return self.__numDeposits
 def getNumWithdrawals(self):
 return self.__numWithdrawals
 def getTotalDeposits(self):
 return self.__totalDeposits
 def getTotalWithdrawals(self):
 return self.__totalWithdrawals
 def Deposit(self,amount):
 self.__balance = self.__balance + amount
 self.__numDeposits = self.__numDeposits + 1
 self.__totalDeposits = self.__totalDeposits + amount
 def Withdrawal(self,amount):
 if (self.__balance >= amount):
 self.__balance = self.__balance - amount
 self.__numWithdrawals = self.__numWithdrawals + 1
 self.__totalWithdrawals = self.__totalWithdrawals + amount
 return True
 else:
 return False
def main():
 list1 = []
 num = eval(input())
 for i in range(num):
 account = input()
 amount = eval(input())
 bankAccount = BankAccount(account,amount)
 list1.append(bankAccount)
 print(list1[i].getBalance())
 while(type != '#'):
 if(type == 'D'):
 account.deposit(amount)
 elif(type == 'W'):
 elif(type == 'T'):
 elif(type == 'B'):

First question: Do list1 and num = eval(input()) go before the main function, or is it good like it is? Second question: Where would type = eval(input()) go? I'm guessing it would go right after the list1 and num? Also, if you could give me some suggestions or tips on how to finish this program, I'd really appreciate it!
