打印最准确分数对应的 k 值，而不是打印分数

Question

如您所见，它当前正在打印分数。我如何简单地打印对应于最高分的 k 值？

k_range = range(1, 26)

scores = []

for k in k_range:
    knn = KNeighborsClassifier(n_neighbors=k)
    knn.fit(X_train, y_train)
    y_pred = knn.predict(X_test)
    scores.append(metrics.accuracy_score(y_test, y_pred))

print(scores)

Answer 1

print( k_range[ scores.index( max(scores) ) ] )

打印最准确分数对应的 k 值，而不是打印分数

Print k value which corresponds to the most accurate score, instead of printing the scores

python

knn
