Steps to write the first Python program HelloWorld with VScode_python

python vscode First

VScode是微软去年推出的一款轻量级编辑器,功能上和Atom、Sublime Text、Vim类似,你可以通过配置将它打造成合适的IDE,这里简单介绍一下,需要的朋友可以参考下

一、软件下载与安装

VScode下载地址:https://code.visualstudio.com/

VScode的github项目地址(本文用不到):https://github.com/microsoft/vscode

Python下载地址:https://www.python.org/downloads/

笔者用的是win版的VScode1.0和32位Python2.7,安装Python时注意将Python添加到系统环境变量

二、VScode项目结构简介

VScode使用的是文件夹命名的项目,也就是说你想写程序的话,需要新建一个文件夹作为你的项目,这个文件夹下放你的源文件,如果需要运行,还需要在这个文件夹下新建.vscode文件夹,在.vscode文件夹下配置这个项目如何运行。

下面是一个典型的项目结构

├─项目名 
│ │ 源文件1 
│ │ 源文件2 
│ │ …… 
│ │ 源文件n 
│ │ 
│ └─.vscode 
│     tasks.json 
│     settings.json
Copy after login

这次配置坑比较多,VScode建议将地区改为en-US,不然的话,有些命令你必须打中文,不能打英文,打中文显示英文结果,打英文没有结果。
当然,本文没改地区

三、安装Python插件

安装Python插件能实现语法提示的一些功能,建议还是安装一下。

打开VScode,查看-->命令面板(Ctrl+Shit+P),输入ext install (中文输入:扩展,然后选择扩展:安装扩展),在出现的搜索结果中选择找到Python,点右边的那一朵小云就可以安装了。

四、新建项目和编辑源代码

新建项目就是新建一个文件夹,笔者先在D盘新建一个PythonProject01的文件夹(这一步在系统里面建,不是VScode里),点击VScode里的资源管理器按钮,点击蓝色的打开文件夹按钮

在D盘找到刚才新建的文件夹,点击选择文件夹

点击新建文件的按钮,文件名填hello.py

在右侧的编辑窗口输入以下代码,保存

# -*- coding: UTF-8 -*-  
print "Hello,World!" 
print "你好,世界!"
Copy after login


五、编辑task.json任务文件并运行该程序

查看-->命令面板(Ctrl+Shit+P),输入Tasks: Configure Task Runner(中文输入:任务,然后选择任务:配置任务运行程序),选择Other

此时VScode会自动生成.vscode文件夹并生成一个默认的task.json

将task.json内容改为如下内容并保存

{ 
  // See http://go.microsoft.com/fwlink/?LinkId=733558 
  // for the documentation about the tasks.json format 
  "version": "0.1.0", 
  "command":"python", 
  //"command":"D:\\Python27\\python.exe", 
  "isShellCommand": true, 
  //"args": ["${file}"], //这种写法不能编译 
  "args": ["hello.py"], 
  "showOutput": "always" 
}
Copy after login

新版本

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
    {
      "label": "echo",
      "type": "shell",
      "command": "d:\\ProgramData\\Anaconda3\\python.exe",
      "args": [
        "1.py"
      ],
      "group": {
        "kind": "build",
        "isDefault": true
      }
    }
  ]
}
Copy after login

运行方法如下:

查看-->命令面板(Ctrl+Shit+P),输入Tasks: Run Build Task(中文输入:任务,然后选择 任务:运行生成任务(Ctrl+Shit+B))

结果如下:

附:将语言更改为en-US

Ctrl+Shift+P,输入语言(Language),选择 配置语言(Configure Language),会自动出现location.json文件

添加"locale":"en-US",如下所示,保存

{ 
  // 定义 VSCode 的显示语言。 
  // 请参阅 http://go.microsoft.com/fwlink/?LinkId=761051,了解支持的语言列表。 
  // 要更改值需要重启 VSCode。 
  "locale":"en-US" 
}
Copy after login

重启VScode即可。
如果想改回中文,就改为"locale":"zh-CN"或者删掉这个location.json文件。
