Скачать или смотреть Python OOP Project: Build a Banking System (Inheritance & Methods) | Python Tutorial #30

Let's build a Bank! In this tutorial, we bring everything we've learned about Object-Oriented Programming (OOP) together to build a functional banking system from scratch.

You’ll see Inheritance in action as we create a Parent 'Account' class and two Child classes: 'Current' and 'Savings'. We’ll implement deposit and withdrawal logic, handle overdraft limits, and use the _str_ dunder method to print beautiful account statements. This is the perfect project to make all those complex OOP concepts finally "click."
