Bank Account Class Design The design for a BankAccount object is laid out in the following class diagram: As you might imagine, the deposit_funds(amount) function adds that money to the current balance of the account, and the withdraw_funds(amount) function removes (i.e. subtracts) money from the current balance of the account. Each transaction in the transaction_list is a tuple containing either the word Deposit or the word Withdrawal followed by an amount, for example: ("Deposit", 300.0) or ("Withdrawal", 100.0). The bank accounts in our program do not have an overdraft facility so the user cannot withdraw money they do not have that is, if they had $200 in their account and they tried to withdraw more than $200 then the operation should fail and the withdraw_funds function should raise an Exception with a suitable error message which is caught and displayed in the main.py file where the operation was attempted. All error messages such as those from exceptions should be displayed in a pop-up messagebox. The get_transaction_string method should loop over all the transactions in the transaction_list creating a string version (with newline characters) of all the transactions associated with the account. The save_to_file function should save the account_number, pin_number, balance, and interest_rate in that order to a file called .txt followed by the transaction list string generated from the get_transaction_string() method. The name of the account file is NOT '.txt' - the name of the file is the ACTUAL ACCOUNT NUMBER followed by ".txt", so for an account with account_number 123456 the name of the account file would be 123456.txt. A full walk-through video demonstrating the completed application and how it operates will be provided along with this assignment document.
