How to create a banking system Python - OOP Tutorial

How to create a banking system using Python that allows for multiple users and bank accounts. In this tutorial, we look at creating a banking system using Object Oriented Programming to allow us to have multiple instances of each class. In this tutorial we brush over OOP Inheritance and class attributes to look at how we can use inheritance to create real world objects with mass scalability. This banking system is a fun terminal project for beginners learning Python to get an understanding of how we can use classes and objects to represent real world objects.

Sorry, but there are bad practices on every line. Starting with bad naming, "Bank" should be named "Account", continue with wrong inheritance, "Bank" should not inherit from "User", there should be a composition of classes. You don't need to check option choices twice whenever check if user_two is not None, and "if user_two is not None" is the preferred syntax for checking. And whole this "options" function (function should be named with verb not noun) is breaking DRY principle. Better practices would be to create an "Option" abstract class, inherit in specialized options classes, and move all attributes and logic there. For option choices, would be wise to use Enum. And if you creating a bank system you should implement transaction logic with rollback and maybe canceling.

How about saving user in file for transaction history ?

[@jirehla-ab1671]

Now how would you transact between 2 or multiple accounts simultaneously?

Is it possible to write a python code that will will automatically download bank statements (e.g. CSV file) from bank website on a daily basis? I want to get rid of signing in to different online accounts just to download the daily, weekly or even monthly statement.

Too small someone can't see what you doing

[@taraalsyah267]

[@mohamedeydy8671]

sir, what's mean f'' string here??

[@__beginnerscode__3584]

An F String is the newest of the ways to format a string. It allows us to input a variable (or function etc) to a string, and output the value inside of the string rather than outputting the variable name
