concat

I want to know how i can concat object fields with a variable, it's hard to explain to me, let me give an example Example: My object have: myobject.name = 'Red' myobject.lastname = 'Foo' and I have a function like this: my function .......... some_dumb_field = name print myobject.some_dumb_field And this crashes!, how can i concat the str of the field like an object? I'm guessing you are looking for getattr : print getattr(myobject, some_dumb_field) This will look up the attribute of myobject whose name is given by the string some_dumb_field . For example, getattr(myobject, 'name') is

I am trying to concat a variable to a regen in c# but it is not working string color_id = "sdsdssd"; Match variations = Regex.Match (data, @""+color_id+"_[^\""]*\""\W\,\""sizes\""\:\s*\W.*?businessCatalogItemId"":\"")", RegexOptions.IgnoreCase);@""+color_id+"_[^\""]*\""\W\,\""sizes\""\:\s*\W.*?businessCatalogItemId"":\"")"; But the above is not working How to concat a variable at starting element to regex in c# The @ identifier only affects the immediately following literal string - you need to apply it to each string that needs it: Match variations = Regex.Match (data,color_id + @"_[^\""]*\""

I have been trying to concatenate two 48 seconds video bits to one using the following command ffmpeg -f concat -safe 0 -i C:\moviepy-master\concat.txt -c copy output.mp4 When I played it using Windows media player the first 48 second plays fine but the player closes before playing the second bit . Then I tried to play it using VLC media player but in the second bit player but the audio and video are not in sync . Then I also tried giving inputs separately so the following error shows up C:\Users\SAMHITA VVNK>ffmpeg -f concat -safe 0 -i C:\moviepy-master\extract1.mp4 -i C:\moviepy-master

Low hours on mysql but starting to probe the edges. Stackoverflow a great resource - thanks everyone. Experimenting with Concat I fell over this issue. I know there will be a way but I just can't figure it out. My example: set @strokes_hole_10 = 6; set @x = 10; set @strokes = concat('strokes_hole_',@x); select @strokes; I looking for @strokes to be the variable value 6 rather than the variable value "strokes_hole_10". I find lots of information on using concat, mostly straight forward examples and I know concat is resulting in a string. I just can't figure out how to make a dynamic label work.

最近团队在搞前端创新，准备引入一些新技术，在同事发的邮件中，看到了淘宝基于nginx开发的静态服务器——Tengine。在“one company”的理念下，公司静态服务器很有可能从独角兽切换到Tengine。现在提前研究下。 对前端而言，Tengine能带来什么？ * 合并多个CSS、JavaScript文件的访问请求变成一个请求； * 强制GZip压缩； 以上2点对一个前端来说，就已经很有吸引了，不是么？ Tengine在2011年底，已经成为一个开源项目。更多介绍可以参考下官网。 官网传送门：http://tengine.taobao.org/index_cn.html 本人的机器是ubuntu，所以下面的安装步骤就是ubuntu的安装步骤了。 1.安装tegine编译库 gcc， zlib1g-dev， libpcre3， libpcre3-dev这些库文件是必须的，会没办法编译tegine ubuntu安装命令： apt-get install gcc libpcre3 libpcre3-dev zlib1g-dev 2.获取tegine，可以通过git或直接下载tar包 （1）克隆源代码：Git clone https: https://github.com/taobao/tengine ～/tengine （2）安装包地址：http://tengine.taobao

So, I have this object containing country names as keys and the values are arrays with some cities. I want to get all the cities in one array, without the countries. Here's how I go about it and can't understand why it isn't working: var cities = { "United Kingdom": ['london'], "Spain": ['ibiza', 'malaga'], "USA": ['hollywood'] } var allCities = []; for (c in cities) { allCities.concat(cities[c]); } console.log(allCities); //gives empty array If I replace allCities.concat(cities[c]) with console.log(cities[c]) I get all the arrays like this: ['london'] ['ibiza', 'malaga'] ['hollywood'] So that

I am trying to concat an individual's first and last name together but coalesce a team name when there is a null value. Unfortunately my syntax is returning a SPACE, so coalesce does not recognize it as a null value.. What can I do to correct this? Syntax I am currently using: coalesce((Concat(first_name,' ',last_name)),team_name) Just use the concatenation operator, || : coalesce(first_name || ' ' || last_name, team_name) The concat() function ignores NULL values. The operator returns NULL . 来源： https://stackoverflow.com/questions/41770098/coalesce-and-concat-in-the-same-statement-postgres
