the underscore character is often used in variable and function names in programming languages. this allows programmers to create more meaningful, readable names for objects and functions, rather than using camelcase or other syntax. for example, instead of "getnumber", a variable could be named ...
A single underscore can be used before a Python variable name. It is like a convention that is used to specify that the variable name is considered now a private variable. It should be considered an implementation detail and subject to change without notice. It gives an idea to programmers t...
Forum General C++ Programming Why _type (underscore before identifier Why _type (underscore before identifier and variable) Pages: 12 Mar 15, 2013 at 10:01pm DeXecipher (458) Why do programmers use underscores to name variables and data types? It grinds my gears a bit. I keep seeing ...
I didn't consider it was from the action key functionality. I can actually overcome it by simply adding an underscore before my variable name. That's not a very elegant solution, but it works. Can you foresee any problem with my doing so? (e.g., lblMyLabel.content = "_" & Data...
From what I understand some times an underscore is used after the variable name to suggest that it is a member variable of a class, but as Disch says using an underscore before should be avoided as it can clash with compiler reserved keywords. ...
_.templateSettings = { interpolate: /\{\{(.+?)\}\}/g }; var template = _.template("Hello {{ name }}!"); template({name: "Mustache"}); => "Hello Mustache!" 默认的,template通过with语句来取得 data 所有的值. 当然, 您也可以在variable设置里指定一个变量名. 这样能显著提升模板的渲染...

There was another proposal, in#1477, to make it possible to reuse variable names in multiple cells so long as multiply defined variables are always defined before they are read. While possible for us to implement, it's somewhat complex (both for the user to understand and for us to implem...
