## Overview

This repository contains two independent, command-line Python assignments: a student grade calculator and a simple shopping cart. Each reads user-provided values, applies its own calculations and conditional rules, then prints a formatted result. The scripts are monolithic, so the stages shown are logical sections within each file, not separate modules. The README documents their behavior; no shared runtime components or external services are shown.

Main entry points: [`student_grade_calculator.py`](https://github.com/kaisermdhashem/python-assignment-module-2/blob/main/student_grade_calculator.py) (Student inputs), [`shopping_cart.py`](https://github.com/kaisermdhashem/python-assignment-module-2/blob/main/shopping_cart.py) (Customer and products)
