Inventory Management System using Python GUI

The Inventory system is developed by Python GUI. The project is built to manage sales and transactions. To make a new transaction, fields such as: short eats and Drink type, qty needs to be selected. If you like to learn Inventory system system step by step, this is the right place to learn from the beginning. In this tutorial useful for making a Inventory system system for a small shops.

i used pycharm editor to writing the code
