import MySQLdb as mdb

con = mdb.connect('localhost', 'root', 'root', 'kuis')

with con:

    cur = con.cursor()
    cur.execute("UPDATE Writers SET Name = %s WHERE Id = %s ",
        ("new_value" , "3"))
    print "Number of rows updated:",  cur.rowcount

使用上面的代码,数据库kuis中表Writer的第三行值用new_value更新,输出将是Number od行更新:1
我应该如何同时更新多行？

我是Csharp ASP.NET和MVC的新手.我正在尝试自定义登录页面,并试图保持一个条件,
检查登录是否经过身份验证.如果登录完成,那么下次用户输入url: localhost:portno/account/login 网址时将被定向到localhost:portno/home/index.我使用了Respond.Redirect methon

@model LearningMvc.Models.LoginViewModel 

完整代码如下:

    @model LearningMvc.Models.LoginViewModel

@{
    ViewBag.Title = "Log in";
}

<h2>@ViewBag.Title.</h2>
<div class="row">
    <div class="col-md-8">
        <section id="loginForm">
            @using (Html.BeginForm("Login", "Account", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
            {
                @Html.AntiForgeryToken()
                if (Request.IsAuthenticated)
                    {
                        Response.Redirect("~/home/index");
    }
                else { 
                        <h4>Use a local account to log in.</h4>
                    <hr />
                    @Html.ValidationSummary(true)
                    <div class="form-group">
                        @Html.LabelFor(m => m.UserName, new { @class = "col-md-2 control-label" })
                        <div class="col-md-10"> …

road= []
distance=[]
i= input ('THE NUMBER OF NODES TO TEST')
for i in range(0,i):
    a = input(' THE NODE NUMBER \n')
    b= input ('ENTER NODE VALUE \n')

    road.append(a)
    distance.append(b)  
    print 'THE NODES AND RESPECTIVE VALUES ARE'
    print "NODES:  \t | \t VALUES:\n " ,words, distance

在上面的python示例代码中,road和distance是两个列表,它们将存储用户输入的值.现在我想在字典中添加这些数据road[0]:distance[0], road[1]: distance[1]等等.即插入列表'road'和'distance'的值应该包含在一个新的字典中,例如'map',它有点像这个map = {"road":"distance"}
