vscode配置python调试(debug)
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}",
"port": 3000,

"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。
