如何使用python调试VSCode上的GoogleCodeJam交互问题？

我试着下载示例交互问题。它们在Description选项卡中提供了一个

本地测试工具

，在Analysis选项卡中提供了一个python解决方案，可以同时运行两个脚本

在将解决方案保存到

solution.py

中后，我可以在shell上使用：

python3 interactive\u runner.py python3 local\u testing\u tool.py 0--python3 solution.py

成功地运行它

问题是我无法使用VSCode调试它。我尝试将所有3个文件放在一个文件夹中，并使用以下launch.json：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Arquivo Atual",
            "type": "python",
            "request": "launch",
            "program": "interactive_runner.py python3 local_testing_tool.py 0 -- python3 ${file}",
            "console": "integratedTerminal",
        }
    ]
}

使用调试器运行solutions.py时，会出现以下错误：

有更好的方法吗？

参数“program”只需要文件的路径，因此会出现“没有这样的文件或目录”的错误。您要做的是将执行行的其余部分作为参数：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Arquivo Atual",
            "type": "python",
            "request": "launch",
            "program": "interactive_runner.py",
            "console": "integratedTerminal",
            "args": ["python3", "local_testing_tool.py", "0", "--", "python3", "${file}"]  // Not sure if `${file}` will work here.
        }
    ]
}

为什么需要指定两次python3？如果

interactive\u runner.py

正在为您运行Python，则可能会阻止调试器工作。@BrettCannon

interactive\u runner.py

运行两个程序（在本例中为Python）：

python3 local\u testing\u tool.py 0

和

python3 solution.py

。它将一个程序的输出作为输入传递给另一个程序。这就是为什么有两个

python3

，实际上它们是3。
