Python 如何从flask中的表中检索值

这是一个生成阿拉伯诗歌的HTML页面

PS：我需要从表中检索诗歌和诗歌。
诗歌是在browser\html页面中生成的？用户是否键入了这首诗？@Mike67不，它是从excel文件生成的。这不是一首输入诗
    elif request.form['action'] == 'Classify':
        train = pd.read_excel('/home/sirina/Desktop/Project/Corpus2/Two-versed Poems/corpusTwoColumnsTrain.xlsx')
        Quasida = [' '.join([x,y]) for x,y in zip(train.Sader, train.Ajez)]
        count_vect = CountVectorizer()
        X_train_counts = count_vect.fit_transform(Quasida)
        tfidf_transformer = TfidfTransformer()
        X_train_tfidf = tfidf_transformer.fit_transform(X_train_counts)
        clf = LinearSVC().fit(X_train_tfidf, train.Era)
        #here i need the poem that i generated to predicted
        predicted=clf.predict(count_vect.transform(poem))
        return render_template('testt.html',poem=poem,prediction=predicted[0])
 return render_template('testt.html')
