Hands‑on tutorial that walks through notebooks and code showing how to scikit-learn models are inspected not summarised: model‑specific vs model‑agnostic methods, partial dependence and permutation importance, plus SHAP caveats. Concrete demos use pipelines, ColumnTransformer, OneHotEncoder, logistic/ridge/lasso, five‑fold CV and report a mean absolute error ≈2.14; shows lasso instability with correlated age/experience, explains scaling and data‑leakage traps, and notes practical binder issues (numpy 1.22 vs 1.21).
