现在去试试:

VSCode中去看看python代码的调试效果如何

现在去拿之前在PyCharm中调试开发的一个Python项目:

去试试,VSCode中:

如何调试,看看效果如何

之前好像是已经安装了对应的Python插件的:

vscode debug python

Debugging Python with Visual Studio Code

Python in Visual Studio Code

“activate it using the Python: Select Interpreter command”

应该先去设置Python解析器

Get Started Tutorial with Python in Visual Studio Code

点击左下角的Python 2.7.10,可以看到列出当前检测到的多个版本的Python解析器

使用VS Code调试Python代码 – PlyTools

VSCode基础使用+VSCode调试python程序入门 – CSDN博客

vscode python设置debug ? – 知乎

使用vscode调试python代码 – CNode技术社区

此处就是用的python 2,所以无须切换python解析器,就用默认检测到的:

Python 2.7.10

即可。

默认配置:

<code>{

    },
    {
      "name": "Python: Attach",
      "type": "python",
      "request": "attach",

      "remoteRoot": "${workspaceFolder}",

        "arg2"
      ],
      "debugOptions": [
        "RedirectOutput"
      ]
    }
  ]
}
</code>

就只是生成了和刚才看到的一样的配置:

<code>    {
      "name": "Python: Current File",
      "type": "python",
      "request": "launch",
      "program": "${file}"
    },
</code>

选择配置:

直接点击运行,结果terminal输出log:

不是debug。

右键:

也没看到如何添加断点的。

也点击了行首,但是无法点击断点:

点击Breakpoint的+去新增断点:

但是好像要自己输入函数?

很麻烦啊。

先后两次点击运行后的log是:

关于添加断点,参考:

https://code.visualstudio.com/docs/languages/python

的Debugging的视频,才看到,原来是行首的空白处,鼠标移动山去可以看到红色点,点击后,即可添加断点:

然后清空了log后,点击debug去调试看看:

注意到,底部有个:

自动附加 默认是 关

看起来,很是不错啊

简单易用的感觉。

然后单步试试

试了试 但不执行

(结果Mac中F11是隐藏所有窗口,所以不得不点击按钮试了试)

结果发现此处的F11,是进入函数内部的单步执行

即:Step Into的效果

注意到:

鼠标移动上去后,显示:

自动附加

的含义了:在调试模式下自动附加到Node.js进程

此处调试Python的话,鼠标移动到对应变量或函数,显示对应的信息:

继续单步:

不过通过鼠标移动到调试按钮栏中发现了:

  • F5:Continue 继续运行 -》直到运行完毕或者遇到断点停下来

  • F10:Step Over

  • F11:Step Into

  • Shift+F11:Step Out

  • Shift+Command+F5:Restart

  • Shift+F5:Stop

总体来说,效果还不错的。

【总结】

VSCode中调试Python的话:

1.先打开当前Python文件

2.左下角选择Python版本(Python解析器)

3.左边切换到(和项目文件列表同级)调试tab

4.点击左上角的调试右边的绿色箭头,在下来列表中选择:添加设置

5.会自动打开launch.json文件,并添加出一个:

Python Current File

之类的配置,配置内容是:

<code>    {
      "name": "Python: Current File",
      "type": "python",
      "request": "launch",
      "program": "${file}"
    },
</code>

6.保存后,关闭launch.json,打开要调试的Python文件,然后去调试:

F5 或 调试->启动调试(F5)

启动调试即可

7.可以根据需要去添加断点

点击每行之前的line number的左边的那一列,即可出现红色点点,左下角的Breakpoints也会出现对应的新的断点。
