## Overview

This repository is a collection of standalone Python learning examples, with a grocery billing script as its most complete user-facing workflow. A shopper enters three items and quantities; the script looks up prices, calculates a subtotal and discount, and prints a receipt. Other scripts demonstrate core Python concepts rather than forming a shared application. The billing stages are represented separately but all live in one file. The broader lesson map is based on filenames; only the billing and selected lesson examples were sampled.

Main entry points: [`Grocery Billing System.py`](https://github.com/zobiamatloob/python/blob/main/Grocery%20Billing%20System.py) (Item costs)
