我在尝试构建一个NFL选秀前景成功概率的模型时遇到了困难，无法找到一种方法来打印出球员的名字及其对应的模型输出。例如，目前输出类似于这样的内容 “[79 22 36 72 20 48 2 68 16 36 11 68 68 16 22 17 60 62 15 17 11 68 0 8428 22 45 48 79 84 2 37 68]”，我希望能同时打印出与这些输出相关的球员。我正在使用我在网上找到的模板代码来构建我想要的模型类型。我将在下面发布代码。

在训练过程中，“Player”列实际上并不重要，因为这些数据是追溯到2004年的历史选秀数据，但显然在最终输出中，当我要求模型预测今年的前景时，我需要输出名字。

    import pandas as pd    import xgboost    from sklearn import model_selection    from sklearn.metrics import accuracy_score    from sklearn.preprocessing import LabelEncoder        # load data    data = pd.read_csv(r"C:\Users\yanke\Documents\NFLDraft\QBDataSet.csv", index_col=0)    dataset = data        # split data into X and y    X = dataset.iloc[:,0:4]    Y = dataset.iloc[:,4]    # encode string class values as integers    label_encoder = LabelEncoder()    label_encoder = label_encoder.fit(Y)    label_encoded_y = label_encoder.transform(Y)        seed = 7    test_size = 0.33    X_train, X_test, y_train, y_test = model_selection.train_test_split(X, label_encoded_y, test_size=test_size, random_state=seed)        # fit model no training data    model = xgboost.XGBClassifier()    model.fit(X_train, y_train)    print(model)        # make predictions for test data    y_pred = model.predict(X_test)    predictions = [round(value) for value in y_pred]        # evaluate predictions    accuracy = accuracy_score(y_test, predictions)    print("Accuracy: %.2f%%" % (accuracy * 100.0))    print(y_pred)

回答：

这会有效吗？

for player, prediction in zip(X_test.index, predictions):  print(player, prediction)
