## Overview

This repository is a hands-on data-science course, not a packaged application. Its user workflow is to run lesson notebooks and practice data analysis and machine learning on realistic data. The README documents exploration, visualization, preparation, model fitting, tuning, validation, and interpretation; the tree shows six lesson notebooks and two credit-default datasets. The sampled Python file is only a basic exercise, so chapter-specific ownership of the README capabilities and dataset usage cannot be established; those links are therefore not inferred.
