在我的项目中,我必须经常重复这部分代码:

class SimplePhysicObject(Object):
    def __init__(self):
        super(Object, self).__init__('SimplePhysicObject')

但不是SimplePhysicObject每次都有新的字符串.有没有办法编写一些宏来使这项工作更容易？就像是:

DoTemplate(NewObject)
==>
class NewObject(Object):
    def __init__(self):
        super(Object, self).__init__('NewObject')

UPD抱歉,Object我之前在代码中声明了我自己的类

是否有一个Python库可以检测(并可能解码)字符串的编码？

我找到chardet但它给了我一个错误,使用:

chardet.detect(self.ui.TextFrom.toPlainText())
got: = chardet.detect(self.ui.TextFrom.toPlainText())
File .... u.feed(aBuf) File .... 
if self._highBitDetector.search(aBuf):

TypeError: buffer size mismatch

也:

print type(self.ui.TextFrom.toPlainText())
# <class 'PyQt4.QtCore.QString'>

我试图在启动后隐藏窗口.我有自己的窗口类,它继承自QMainWindow.我重写了这样的showEvent:

void showEvent (QShowEvent *evt)
{
   if (firstShow)
   {
     hide();
     firstShow = false;
   }
   else
   {
      QMainWindow::showEvent(evt);
   }
}

但它不起作用.firstShow是一个布尔变量,在开始时是真的.语言:c ++

我需要网页内容.我需要从中获取一些数据.看起来像:

<div class ="deg"> DATA </ div>

据我所知,我必须使用正则表达式,但我不能选择一个.

我尝试了下面的代码,但没有任何结果.请纠正我:

regexHandler = re.compile('(<div class="deg">(?P<div class="deg">.*?)</div>)')
result = regexHandler.search( pageData )

我正在尝试运行aap-application.版本是1.076(尝试更高).所有命令都向我发送错误,如:

> Traceback (most recent call last):

我之前做过......但我忘记了.我有一个包含一些数据的文件:

0.5 0.6 0.7 1.2 1.5

如何在c ++中阅读？我用流做了...类似于:

float var = 0;
stream >> var;

解析错误:语法错误,意外的T_STRING,在第9行/home3/*/www/modules/mysql_worker.php中期待T_OLD_FUNCTION或T_FUNCTION或T_VAR或'}'

这是文件mysql_worker.php http://pastie.org/697284

无法理解mysql错误:

UPDATE static_pages SET order ="一些新数据222222

"数据库错误:您的SQL语法中有错误;请查看与您的MySQL服务器版本对应的手册,以便在'order ='附近使用正确的语法

$query = 'UPDATE someTable SET '.$key.' = "'.$value.'"';

这是$ key = order; $ value ='新数据222222'; 表中有这样的键:订单,价格,联系方式.除"订单"外,其中每个都更新.为什么？

我有一些div块.我需要缩放它自己的大小.就像在MacOS停靠面板中一样,当图标悬停时.我可以这样做吗？
