vscode作为宇宙级编辑器，已经越来越多人开始使用它。而它的扩展也琳琅满目，在这里我们介绍下vscode下如何进行python开发和调试。

首先，我们需要安装python扩展，打开编辑器，输入ctrl+p,然后输入命令ext install打开扩展搜索。

在扩展里面搜素python扩展，然后安装。

创建一个文件夹，然后使用vscode打开这个文件夹

创建一个文件，然后命名为index.py。

配置调试文件，创建launch.json文件。文件内容如下:{

// 使用 IntelliSense 了解相关属性。

// 悬停以查看现有属性的描述。

"remoteRoot": "${workspaceRoot}",

"host": "localhost"

}

]

}

6.配置任务文件tasks.json.内容如下：{

// See https://go.microsoft.com/fwlink/?LinkId=733558

// for the documentation about the tasks.json format

"version": "2.0.0",

"tasks": [

{

"taskName": "echo",

"type": "shell",

"command": "D:\\Program Files (x86)\\Python37-32\\python.exe",//Python可执行文件路径

"args": ["${file}"]

}

]

}

7.设置断点，启动调试

经过上面的步骤，我们就可以变量框中看到本地变量，还可添加监视变量。

launch.json是调试的核心，各个语言都需要这个文件来进行调试，实际上是通过这个文件来调用语言自带的调试工具来调试。
