Vending Machine Project

I'd like to design and implement a ‘Vending Machine’ for drinks, snack, masks, train tickets, fruits, ice-cream or some other product of your choice. Client/ Server-side software system should be built in Python to interact with the user on the client-side and the data storage should be process on the server-side. The client program should have an intuitive user interface to view available items and prices, create order, (add, remove item), manage order and payment. The server program should allow one client (multiple clients for the advance version of the software) interact with the current stock (database) of a product and interact, update the stock based on the orders done by the client. I'd like the task to be coded via python and the gui with tkinter along side the data for the vending machine must be server scripted. for more information on the task and scenario please give me a message for a full briefing.
