A user can create a bank account at the start menu, where a card number and its pin will be automatically generated for the user.
A card number is made up of an Issuer Identification Number IIN (here, it is 400000), a Customer Account Number CAN (here, a unique 9-digit number), and a check digit that makes sure the number of the card is valid using the Luhn algorithm. Each created card number will fit this description.
If the user wishes to log into an account, they will have to input a valid card number and pin (i.e. one which was already automatically created). After that, the user has 6 options:
1 - Balance: The user can check the balance available in the account
2 - Add income: The user can add any amount of valid positive income to the account
3 - Do transfer: The user can attempt to transfer from this account to another already created account a valid amount of money
4 - Close account: This will delete the account
5 - Log out: This will log out the user from the current account.
0 - Exit: This will exit the user from the program.
To avoid the data disappearing after the completion of the program, every created account will be stored in a database (using sqlite3) so that they are accessible during every run of the program.
This simple database will store a single table card with the following columns:
(id INTEGER, number TEXT, pin TEXT, balance INTEGER DEFAULT 0).
Find out how the banking system works and learn about SQL and databases. See how the Luhn algorithm can help us avoid mistakes when entering the card number and learn basic OOP concepts such as classes.

This project's difficulty has been labelled as Hard where this is how HyperSkill describes each of its four available difficulty levels:
- Easy Projects - if you're just starting
- Medium Projects - to build upon the basics
- Hard Projects - to practice all the basic concepts and learn new ones
- Challenging Projects - to perfect your knowledge with challenging tasks
This Repository contains one .py file:
bank.py - Contains the code used to achieve the program's purpose
Project was built using python version 3.11.3
Download the bank.py file to your local repository and open the project in your choice IDE and run the project. After a single run of the program, a database card.s3db would have been created in the same working directory.
