How to do multiple imports in Python?

由 天涯浪子 提交于 2019-11-26 20:08:54
问题 In Ruby, instead of repeating the "require" (the "import" in Python) word lots of times, I do %w{lib1 lib2 lib3 lib4 lib5}.each { |x| require x } So it iterates over the set of "libs" and "require" (import) each one of them. Now I'm writing a Python script and I would like to do something like that. Is there a way to, or do I need to write "import" for all of them. The straight-forward "traduction" would be something like the following code. Anyway, since Python does not import libs named as

Node-style require for in-browser javascript?

由 若如初见. 提交于 2019-11-26 19:42:49
Are there any libraries for in-browser javascript that provide the same flexibility/modularity/ease of use as Node's require ? To provide more detail: the reason require is so good is that it: Allows code to be dynamically loaded from other locations (which is stylistically better, in my opinion, than linking all your code in the HTML) It provides a consistent interface for building modules It is easy for modules to depend on other modules (so I could write, for instance, an API that requires jQuery so I can use jQuery.ajax() Loaded javascript is scoped , meaning I could load with var dsp =

js中import和require的区别

js中import和require的区别 ES6标准发布后，module成为标准，标准使用是以export指令导出接口，以import引入模块。但是在我们一贯的node模块中，我们依然采用的是CommonJS规范，使用require引入模块，使用module.exports导出接口。 require 它相当于module.exports的传送门，module.exports后面的内容是什么，require的结果就是什么，对象、数字、字符串、函数……再把require的结果赋值给某个变量，相当于把require和module.exports进行平行空间的位置重叠。 require理论上可以运用在代码的任何地方，甚至不需要赋值给某个变量之后再使用。 require('./a')(); // a模块是一个函数，立即执行a模块函数 var data = require('./a').data; // a模块导出的是一个对象 import impor它是编译时的（require是运行时的），它必须放在文件开头，而且使用格式也是确定的，不容置疑。它不会将整个模块运行后赋值给某个变量，而是只选择import的接口进行编译，这样在性能上比require好很多。require是赋值过程，import是解构过程 require 和 import的区别 require引入基础数据类型时，属于复制该变量

The difference between “require(x)” and import x

问题 I've just started working on a small node project that will interface with a MongoDB. However, I cannot seem to get the relevant node modules to import correctly, even though I have installed them correctly via npm . For example, the following code throws and error, telling me that "express has no default export": import express from "express"; However, this code works: const express = require("express"); So my question is, what is the difference in how the import and variable/require methods

问题 This question already has an answer here: How do I add PHP code/file to HTML(.html) files? 10 answers I'm working on a project that may have to change the same content on all html pages.

React Native: require() with Dynamic String?

由 这一生的挚爱 提交于 2019-11-26 17:27:08
问题 I have read several posts about issues that people are having with React Native and the require() function when trying to require a dynamic resource such as: Dynamic (fails) : urlName = "sampleData.json"; data = require('../' + urlName); vs. Static (succeeds) : data = require('../sampleData.json'); I have read on some threads that this is a bug in React Native and in others that this is a feature. Is there a new way to require a dynamic resource within a function? Related Posts (all fairly

Load node.js module from string in memory

How would I require() a file if I had the file's contents as a string in memory, without writing it out to disk? Here's an example: // Load the file as a string var strFileContents = fs.readFileSync( "./myUnalteredModule.js", 'utf8' ); // Do some stuff to the files contents strFileContents[532] = '6'; // Load it as a node module (how would I do this?) var loadedModule = require( doMagic(strFileContents) ); function requireFromString(src, filename) { var Module = module.constructor; var m = new Module(); m._compile(src, filename); return m.exports; } console.log(requireFromString('module

What's the best way to require all files from a directory in ruby ? Sam Stokes How about: Dir["/path/to/directory/*.rb"].each {|file| require file } jandot If it's a directory relative to the file that does the requiring (e.g. you want to load all files in the lib directory): Dir[File.dirname(__FILE__) + '/lib/*.rb'].each {|file| require file } Edit: Based on comments below, an updated version: Dir[File.join(__dir__, 'lib', '*.rb')].each { |file| require file } Try the require_all gem: http://github.com/jarmo/require_all https://rubygems.org/gems/require_all It lets you simply: require_all
