如何使用 python 在 VSCode 上調試 Google Code Jam 交互問題？

Question

我嘗試下載示例交互式問題數字猜測問題。 他們在描述選項卡中提供local testing tool ，在分析選項卡中提供 python 解決方案，同時運行兩個腳本的interactive_runner.py 。

將解決方案保存在solution.py后，我可以在 shell 上成功運行： python3 interactive_runner.py python3 local_testing_tool.py 0 -- python3 solution.py 。

問題是我無法使用 VSCode 調試它。 我嘗試將所有 3 個文件放在一個文件夾中並使用以下啟動。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",
        }
    ]
}

當我使用調試器運行solutions.py 時，出現錯誤：

關於如何做到這一點有更好的方法嗎？

"program"參數只需要文件的路徑，因此會出現“沒有這樣的文件或目錄”的錯誤。 您要做的是獲取執行行的 rest 並將它們設為 arguments：

{
    "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.
        }
    ]
}
