本篇文章带大家了解一下VSCode中配置Python的方法,实现写Python时的代码错误提醒和自动格式化功能。

How to configure Python in VSCode to implement error reminders and automatic formatting

Come on!Python 代码错误检查:

Python 的代码错误检查通常用 pep8、pylint和flake8,自动格式化代码通常用 autopep8、yapf、black。这些工具均可以利用pip进行安装,这里介绍传统的利用 pip.exe 安装和在 VScode 中安装两种方式。【推荐学习:《vscode教程》】

如果要使用 flake8 或要想 flake8 等工具起作用,前提是必须把 settings.json 文件中的"python.linting.enabled"值设为“true”,否则即使安装了这些工具,也起不到代码的错误提醒。

// python相关配置
  "python.linting.flake8Enabled": true,
  "python.formatting.provider": "yapf",
  "python.linting.flake8Args": [
    "--max--line-length=248"
  ],
  "python.linting.pylintEnabled": false,
  "workbench.startupEditor": "newUntitledFile",
  "python.pythonPath": "C:\\Users\\lenovo\\AppData\\Local\\Programs\\Python\\Python37\\python.exe",
  "python.linting.enabled": true,
  "editor.fontSize": 14, 
  // 截止python相关配置
Copy after login

把上述配置放入 settings.json

【传统安装方式】

以安装为例 flake8,其余类似

方法一:

  • 打开命令行窗口(同时按 Win+R,输入cmd

  • 输入:python -m pip install flake8,回车运行等待结果即可

【注意】前提是必须将python的路径添加至环境变量。

方法二:

  • 打开命令行窗口(同时按 Win+R,输入cmd

  • pip.exe 直接拖进cmd窗口

  • 输入:pip install flake8,回车等待运行结果即可

方法三:

  • pip.exe 所在的目录,按 Shift+鼠标右键 ,打开 PowerShell窗口win10 以前的版本是可以直接打开命令行窗口)

  • 输入:cmd,回车运行

  • 输入:pip install flake8,回车等待运行结果即可


【在 Vscode 中安装】**

代码错误工具以 flake8 为例:

1、在 VScode 中打开设置,搜索 python.linting.flake8enabled

2、在 Settings 界面中勾选

  • Whether to lint Python files using flake8

【在Vscode中安装格式化】VsCode 当你按下格式化快捷键 "Alt+Shift+F" 时,右下角会提示安装 autopep8自动格式化工具,点击yes等待安装完毕再格式化即可。
