嗨,我对编码很新,我坚持否定以及如何正确实现它.我已经经历教科书自学,我卡壳"写一个声明,如果否定N,当且仅当它小于0"

我已经尝试过并且失败了,任何提示或帮助将不胜感激.

if -n > 0:
n = 1

我的数据库列名是"从"但我收到错误,而我将列名更改为其他名称错误未发生.为什么？

    protected void Button1_Click(object sender, EventArgs e)
    {
    SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["Mycon"].ConnectionString);
    con.Open();
    string qry="insert into Mynew(name,age,from,address,job)values(@name,@age,@from,@address,@job)";
    SqlCommand cmd= new SqlCommand(qry, con);
    cmd.Parameters.AddWithValue("@name", TextBox1.Text);
    cmd.Parameters.AddWithValue("@age", TextBox2.Text);
    cmd.Parameters.AddWithValue("@from",TextBox3.Text);
    cmd.Parameters.AddWithValue("@address", TextBox4.Text);
    cmd.Parameters.AddWithValue("@job", TextBox5.Text);
    cmd.ExecuteNonQuery();
    con.Close();
    }

当我将列名更改为城市时我没有收到错误为什么会发生？

我正在编写一个工作程序,我从.txt文档中提取两个名字.我已经编写了一个程序来获取名称但我需要更改它,以便我可以给每个名称一个被选中的概率.这个概率会随着我的审核而改变.我怎么能用Python做到这一点？我附上了我迄今为止所做的代码,但我不知道如何使它具有不同的概率.

import os
os.chdir('C:/Users/Lance/Documents/Teams')
with open('San_Diego.txt') as taf:
    data = taf.readline()
San_Diego = data.strip().split(',')
with open('OCIE.txt') as oaf:
    data = oaf.readline()
OCIE = data.strip().split(',')   
def picker(seq):
    from functools import partial
    from random import choice
    return partial(choice, seq)
team_picker = picker(San_Diego)
print([team_picker() for c in range(2)])
team_picker = picker(OCIE)
print([team_picker() for c in range(2)])

嗨我怎么能在数组内执行此操作.当速度低于10Kph时,我希望REMARKS显示"已停止"一词

这是我的代码

array(
                  'account' => $rowmaxtec['ACCOUNT'],
                  'trxdate' => $rowmaxtec['TRXDATE'],
                  //'trxtime' => date('H:i:s',strtotime("+8 Hours",strtotime($rowmaxtec['gpsdate'] . ' ' . $rowmaxtec['gpstime']))),
                 // 'trxtime' => $gpsdatetimeg,
                 'trxtime' => $philtime,
                  'long' => $rowmaxtec['LONG'],
                  'lat' => $rowmaxtec['LAT'],
                  'location' => callback($rowmaxtec['LOCATION']),
                  'direction' => $rowmaxtec['DIRECTION'],
                  'compass' => $rowmaxtec['COMPASS'],
                  'id' => $rowmaxtec['ID'],
                  'events' => $rowmaxtec['Events'],
                  'remarks' => $rowmaxtec['REMARKS'],    -----------------------REMARKS
                  'status' => $rowmaxtec['devicestatus'],
                  'kmrun' => $kmrun,
                  'speed' => $rowmaxtec['speed'],          <------if this is  less than 10kph then REMARKS must be masked/overwritten by the word Stopped
                  'totalkm' => $total,
        'engine' => $rowmaxtec['ENGINE'] …

在android中,我在解析时得到了错误的日期.我提供22 Feb (Wednesday).为什么它给我错误的工作日(星期日)？请查看下面的屏幕截图,查看包含值的完整代码.

SimpleDateFormat format = new SimpleDateFormat("dd MMM (EEEE)");
try {
    Date date = format.parse(strDate);
    Calendar c = Calendar.getInstance();
    c.setTime(date);
    c.add(Calendar.DATE, 2);
    String output = format.format(c.getTime());
    tvDeliveryDate.setText(output);
    tvDeliveryTime.setText(time);
    deliveryDateTime = output + "," + time;
    db.putString("deliver_date",output);
    db.putString("deliver_time",time);
    db.putString("deliver_date_time",output + ", " + time);
} catch (ParseException e) {
    e.printStackTrace();
}

我有一个包含数字的字符串,.我想,在第一个字符之前删除它.

输入是,1,2,3,4,5,6,7,8,9,10,并且此代码不起作用:

results.replaceFirst(",","");
