## Overview

This repository is a collection of introductory Python learning exercises, not a single application. The learner runs standalone scripts that read input, perform a small programming task, and print a result. Examples cover basic values and strings, arithmetic and unit conversions, interactive selection and grading, simple games, and list operations. The tree shows repeated exercise versions across course days; they are independent examples rather than a shared runtime. Only sampled scripts were inspected, so links represent behavior visible in those files, not a common execution framework.
