def remove_whitespaces(value):
"Remove all whitespaces"
p = re.compile(r'\s+')
return p.sub(' ', value)
The above code strips tags but doesn't remove "all" whitespaces from the value.
Thanks
How can queries like
SELECT * FROM sometable WHERE somefield LIKE '%value%'
be optimized?
The main issue here is the first wildcard which prevents DBMS from using index.
Edit: What is more, somefield value is solid string (not a piece of text) so fulltext search could not be performed.
I am using Jacob jar file in my java application.
This Jacob jar file comes with a .dll file. I have added Jacob jar file to my classpath. But when I execute my application a runtime error occurs as
"couldn't load jacob-1.15-M3-x86.dll file"
How can I load this .dll file?
Edited:=================================================================================
I had set the "path" environment varaible to the dir that contains my .dll file and loading that .dll file as follows
static {
System.loadLibrary("jacob-1.15-M3-x86.dll");
}
but the following …
I have a c console app which converts a c file to a html file, the c file location is passed to the program as a command line argument.(the app is for the windows platform)
What I would like to do is have a python gui app to allow the user to select a file and pass the location of the file to the c app for processing.
I already know how to create a basic python gui with tkinter, …
我想将二进制文件传输到远程服务器.我在我的代码中使用SUN/ONC RPC(Linux上的rpcgen).我正在使用C.我已经为服务器和客户端编写了代码,它适用于文本文件,但是当我尝试传输二进制文件时,它表示文件在传输后已损坏.我将数据块存储在字符数组或XDR字符串中.我认为将数据存储为字符数组存在一些问题.有人可以告诉我这是什么问题吗？有人可以帮帮我吗？
我在这里附上我的代码片段以供参考,如果有人想看看我在做什么.
我的IDL:
const MAXLEN = 1024;
/*
* Type for storing path
*/
typedef string filename<MAXLEN>;
/*
* Structure for sending request. Expects the path of the file

struct request {
filename name;
int start;
};
/*
* Type that represents the structute for request
*/
typedef struct request request;

如果有人点击链接,Google Adwords不会为您的网页添加任何代码来计算转化次数.但是因为它是Javascript,我相信有一种方法可以做到这一点.
以下是Google为您提供的代码(未经更改),您可以将其视为转化(大部分时间都是感谢页面):
<!-- Google Code for Klick Conversion Page -->
<script type="text/javascript">
<!--
var google_conversion_id = 1062751462;
var google_conversion_language = "de";
var google_conversion_format = "1";
var google_conversion_color = "ffffff";
var google_conversion_label = "dKXuCODvugEQ5pnh-gM";
var google_conversion_value = 0;

使用其他转换跟踪脚本,必须执行一些功能来计算转换.在这里,只需将JS-File添加到您的页面就足以触发转换跟踪,因为conversion.js会在加载时调用一个函数(下载它并在通过代码测试器运行它之后查看它,这真是相当不错的工作!).
知道怎么解决这个问题吗？
好吧,我知道一点HTML,我只是想玩它.我想知道,人们通常是从头开始编写网站,还是使用模板,还是使用WYSIWYG编辑器？
对我来说,似乎从头开始写作是不必要的,现在,我们有编辑和模板,但也许我最好尝试从头开始从学习目的写一些东西？
所以,如果我想比我更好地学习HTML,那么最好的方法是什么(我可以访问免费服务器)以及专业网站创建者如何做到这一点？也许这是一个明显的答案,但我很陌生.谢谢!
当我将一个文件从一个位置移动到另一个位置时
rename('path/filename', 'newpath/filename');
如何将文件夹中的所有文件移动到另一个文件夹？尝试了这个没有结果:
rename('path/*', 'newpath/*');
