每次通过在python中调用相同的方法来运行程序时，如何获得不同的输出？

Question

下面是most_informative_feature_for_binary_classification方法：

def most_informative_feature_for_binary_classification(vectorizer, classifier, n=100):
        """
        Identify most important features if given a vectorizer and binary classifier. Set n to the number
        of weighted features you would like to show.
        """
        # additional stopwords to be remove
        # Open a file and read it into memory
        file = open('..\stopwords.txt')
        additional_stopwords = file.read()
        additional_stopwords = additional_stopwords.split()

        class_labels = classifier.classes_
        feature_names = vectorizer.get_feature_names()
        feature_names = [word for word in feature_names if word not in additional_stopwords]

        topn_class1 = sorted(zip(classifier.coef_[0], feature_names))[:n]
        topn_class2 = sorted(zip(classifier.coef_[0], feature_names))[-n:]

        # class_labels = category
        # coef = co-effecient
        # feat = most informative feature
        for coef, feat in topn_class1:
            print(class_labels[0], coef, feat)

        print()

        for coef, feat in reversed(topn_class2):
            print(class_labels[1], coef, feat)

目前，我只能打印2类for循环中上面显示的两个类别...

但是我想每次程序运行时得到2个不同的类别... 例如，第一次运行程序->输出将为3和4类，第二次运行程序将为4和5类 第三次运行程序：5级和6级 第4次程序运行：第6和第7类 第五次运行程序：7年级和8年级 它将再次经历这个循环

请帮助我看看我的代码：（（
