python - 如何使用 python 调试 VSCode 上的 Google Code Jam 交互问题？

问题描述

我尝试下载示例交互式问题数字猜测问题。他们local testing tool在“描述”选项卡中提供了一个，在“分析”选项卡中提供了一个 python 解决方案，一个同时运行两个脚本的interactive_runner.py 。

将解决方案保存在 a 中后solution.py，我可以在 shell 上成功运行它python3 interactive_runner.py python3 local_testing_tool.py 0 -- python3 solution.py：

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",
        }
    ]
}

当我使用调试器运行solutions.py 时，出现错误：

关于如何做到这一点有更好的方法吗？

解决方案

该"program"参数只需要文件的路径，因此有关“没有这样的文件或目录”的错误。您想要做的是获取执行行的其余部分并将它们作为参数：

{
    "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.
        }
    ]
}
