Bank Transaction System v2.2.3

Made by @Georgegreece This System was made as a fun little side project and it's still just that. It has many features already and more will come. The account information is saved locally, as the idea is for this program to be used in ATMs or something similar.

Accounts

Each account is stored in the Accounts dictionary. The accounts' dictionary names are stored using p and their unique ID For example the first user would be p1, second user would be p2 etc.

Each account has a unique Transaction Number used for money transfers. The Transaction Number is created by the newAccountNumber() function. We create the accounts using our Person() class. Example:

Accounts["p1"] = Person("John D.", newAccountNumber(), 0)

Also, each account has a log dictionary where it stores it's logs. The logs are stored with the YEAR-MONTH-DAY-HOUR:MINUTE format. Example:

print(Accounts["p1"].log["2017-07-21-15:32"])

This should return the exact transaction that happened on that date and time. The program uses the saveLog() function. It is not recommended to save manually unless implementing a new feature. But here it is: Function saveLog(money,action,accTo) Example:

Accounts["p1"].saveLog(444,"t",221)

Saves a transaction log depending on the specified action

"d" = Deposit
"t" = Transfer
"w" = Withdraw

Note: Only transfers need the accTo, for everything else just send an empty string

Functions

Return Codes

Return codes are an important way of knowing what happened in the program. Here's a list of the codes and what they mean. You can also find the codes on the top of the Bank.py file.

0 = Success
1 = Not A Number
2 = Number Bellow Zero
3 = Not Enough Money
4 = Account Not Found
5 = Account Equals Current Account
6 = Account Number Not A Number
7 = Pin Length Not 4
8 = Incorrect Pin
9 = Unexpected Error (AKA this shouldn't be happening)
