🍱 Banking System With Python OOP

📌 Description

This Application, use Python OOP skills to build out a banking application that allows users to view their checking and savings account balances, make deposits and withdrawals from either account, and transfer from savings to checking or vice versa. After each transaction, the users should be able to view their updated balances.

  • Motivation: Practice OOP in Python through a real-world banking app simulation.
  • Purpose: Create a CLI tool for managing checking and savings accounts.
  • Problem Solved: Simplifies tracking of account activity with input validation and logic.
  • What I Learned: Core OOP concepts like inheritance, abstraction, and input validation in Python.
