通过：
初学python，pycharm和Spyder哪个好？ – 知乎
-》
Python – Visual Studio Marketplace
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
“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
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>{

}
</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。
