1、单独安装 不同版本的 Python 解释器，或 Anaconda；
2、安装 VSCode，及中文、相关Python 开发的插件；
重点有： （1）虚拟环境配置插件。
3、配置 settings.json ，这个文件主要配置 编辑器、文件等相关的（工作空间 WorkSpace、即项目文件夹）设置项。
用户（User）设置项 是VSCode 全局性的。示例如下
{
"python-envs.defaultEnvManager": "ms-python.python:system",
"python-envs.pythonProjects": [],
"editor.fontSize": 18, ------ 改变编辑器字体大小
"editor.formatOnSave": true,
"editor.formatOnPaste": true
}
4、运行与调试 配置：launch.json， 以便在运行和调试代码时提供特定的参数和配置。 这个比较麻烦。 参考官方文档：Python debugging in VS Code
点击侧边栏的“运行和调试”图标，有 一个 “创建 launch.json 文件” 的连接按钮，可以生成配置文件 launch.json。 示例如下，保障能用！
它定义了调试器如何启动和运行程序，最重要的就是四块内容：文件路径、传入参数、虚拟环境、工作路径。
{
"version": "0.2.0", ----- 版本，非必需
"configurations": [
{
"name": "Python Debugger: Python File 主文件", ------ 名称 ，好像没有很大影响，你看着办
"type": "debugpy", ------ 新的变化 debugpy，以前是：python
"request": "launch", ------ 有两个选择：设置为 "launch" 以启动程序，或者 "attach" 以附加到已运行的进程。
"program": "${file}", ------ 要调试的 Python 脚本的路径。你可以使用 ${file} 来指定当前打开的文件，
或者指定具体文件的路径。例如，"program": "${workspaceFolder}/script.py"。
或 "module": "xxxbb" ------ 要调试的 Python 模块的路径。 program 与 module，二选一。
"console": "integratedTerminal", ------ 指定调试器使用的控制台类型。例如，"integratedTerminal" 是使用 VSCode 的集成终端。
"args": [ ------ 为程序传递的命令行参数。例如，"args": ["arg1", "arg2"]， "args": "${command:pickArgs}"。
"arg1",
"arg2"
],
"env": { ----- 设置环境变量。例如，"env": {"VAR1": "value1"}。
"VAR1": "value1"
},
"cwd": "${workspaceFolder}" ----- 设置工作目录。例如，"cwd": "${workspaceFolder}"
}
]
}
