值以字符串而不是列表形式返回

Question

这是一个html链接，我希望在其中解析值并将其发送到列表中的python函数，但是由于某些问题，它以字符串形式返回。

我尝试通过eval（）和item.list（）将其转换为列表，但无法转换数据类型

@app.route("/verify/")
def verify():
    cursor = connection.cursor()
    cursor.execute('SELECT `Name`, `Email_ID`, `Phone_No`,`Activation` FROM `user_master` where UTMID = 3')
    data = cursor.fetchall()
    if data:
        print(data)
    return render_template('admin/verification.html',data=data)

上面的功能verify是显示项目，下面的功能verifys是获取值并将其更新到表中

@app.route("/verifyscr/<string:item>",methods=['GET',"POST"])
def verifyscr(item):
    #item = eval(item)
    print("-----",type(item))
    if 'pending' in item:
        print('pending')
        cursor = connection.cursor()
        cursor.execute('UPDATE user_master SET Activation = "activated" WHERE Email_ID =%s',(item[1]))
        msg = Message('Activation',recipients = ['parikh.madhav1999@gmail.com'])
        msg.body = "Hello Flask message sent from Flask-Mail"
        mail.send(msg)
        connection.commit()
        cursor.close()
    elif 'activated' in item:
        print('activated')
        cursor = connection.cursor()
        cursor.execute('UPDATE user_master SET Activation = "pending" WHERE Email_ID =%s',(item[1]))
        connection.commit()
        cursor.close()
    return str(item)

{% for item in data %}
        <tbody>
            <tr>
                <td>{{item[0]}}</td>
                <td>{{item[1]}}</td>
                <td>{{item[2]}}</td>
                <td>{{item[3]}}</td>
                {% if item[3] == "activated" %}
                <td><a href='/verifyscr/{{ item[1],item[3] }}'>Change Status</td>
                {% endif %}
                {% if item[3] == "pending" %}
                <td><a href='/verifyscr/{{ item[1],item[3] }}'>Change Status</td>   
                    {% endif %} 
            </tr>
        </tbody>
        {% endfor %}
