【问题描述】：

我正在尝试将下拉选择列表的列添加到数据框中，然后再将其存储到 FLASK、SQLAlchemy、Python 中的 mysql。你能帮忙吗？得到错误：

TypeError: 'method' object is not subscriptable

以下是用于项目的两个文件。 app.py 和 view_two.html。基本上，我正在开发将所有银行对帐单excel文件提交到mysql的应用程序。首先，我使用 PANDAS 通过将 df 转换为字典来查看数据框。现在在发送到 mysql 之前，我想为每笔交易分配类别，无论是清洁费用、银行费用、食品费用等。

app.py

@app.route('/submit_two', methods=['GET', 'POST'])
def submit_two():
    category = (request.form.get['category'])
    a_two = session.get('a_two')
    df = pd.DataFrame(a_two)
    df['Categories'] = category
    new_data_two = df.to_dict(orient='record')
    a_two = new_data_two

    if request.method == 'POST':
        # df.fillna(0)
        # a_two.fillna(0)
        for data in a_two:
            fav_two = BankData(process_date=data.get('Process date'), description=data.get(
                'Description'), debit=data.get('Debit'), credit=data.get('Credit'), balance=data.get('Balance'), category=data.get('Categories'))
            db.session.add(fav_two)
            db.session.commit()

        print("Bank data submitted")
        return render_template("index.html")

【解决方案1】：

您的线路： category = (request.form.get['category'])

应该是：category = (request.form.get('category'))
