Train score vs test score

Make 0/1 columns diabetic_flag (from diabetic), weekend_flag (from weekend_discharge) and readmit (from readmitted), 1 meaning Yes. The inputs are age, length_of_stay, medications, prior_visits, diabetic_flag and weekend_flag; the answer is readmit. Split with train_test_split (test_size=0.25, random_state=42, stratify on the answer).

Train DecisionTreeClassifier(random_state=0) (no limits) and store [train accuracy, test accuracy], each rounded to 3 decimals, in result.
