My Computer Science lessons have been focused on Object Orientated Programming, but the code provided as an example seems to be malfunctioning.
class bankAccount():
'''This is a bank account class'''
def __init__(self, account_name = "Bank Account", balance = 1500):
self.__account_name = account_name
self.__balance = balance
def deposit(self, value):
self.__balance = self.__balance + value
print("You now have: ", self.__balance)
def withdraw(self, value):
self.__balance = self.__balance - value
print("You now have: ", self.__balance)
class currentAccount(bankAccount):
'''This is a current account class'''
def __init__(self, account_name = "Current Account", balance = 1500):
self.__account_name = account_name
self.__balance = balance
super().__init__()
def withdraw(self, value):
if value > 1000:
print("You will have to phone the bank manager")
else:
self.__balance = self.__balance - value
print("You now have: ", self.__balance)
class savingsAccount(bankAccount):
'''This is a current account class'''
def __init__(self, account_name = "Savings Account", balance = 1500):
self.__account_name = account_name
self.__balance = balance
super().__init__()
def deposit(self, value):
self.__balance = self.__balance + (value *1.03)
print("You now have: ", self.__balance)
currentObject = currentAccount()
savingsObject = savingsAccount()
while True:
print("1. Current Account")
print("2. Savings Account")
menu_option = int(input())
if menu_option == 1:
print("1. Deposit funds")
print("2. Withdraw funds")
submenu_option = int(input())
if submenu_option == 1:
value = int(input("How much would you like to deposit? "))
currentObject.deposit(value)
elif submenu_option == 2:
value = int(input("How much would you like to withdraw? "))
currentObject.withdraw(value)
else:
print("Wrong menu choice!")
elif menu_option == 2:
print("1. Deposit funds")
print("2. Withdraw funds")
submenu_option = int(input())
if submenu_option == 1:
value = int(input("How much would you like to deposit? "))
savingsObject.deposit(value)
elif submenu_option == 2:
value = int(input("How much would you like to withdraw? "))
savingsObject.withdraw(value)
else:
print("Wrong menu choice!")
else:
print("Wrong menu choice!")
input()
Upon examination, it appears that distinct data is saved for each withdrawal and deposit transaction. This leads to discrepancies in the balance when performing these operations. If you were to deposit $100 into a savings account and then withdraw $100, instead of calculating (1500 + 100) = 1600 followed by (1600 - 100), the program defaults to using 1500 as the initial balance, resulting in different balances for deposits and withdrawals.
I am seeking assistance with this issue since I am new to OOP and unable to discern the cause behind this behavior. Any guidance provided would be highly valued.
