Python 使用 osascript 将文件路径变量传递到 Applescript

Question

我正在尝试从 Python 将文件路径传递到 n Applescript 中，不知道如何实现它。下面的代码显示了工作的 Applescript 代码，它提示打开一个或多个文件，然后重新分配音频 channel ，保存并关闭。我不想提示输入一个或多个文件，而是想将文件路径传递到 osascript Applescript 中，我已经设置了参数，但不确定如何让它工作。

找到答案了。需要将运行部分更改为:

on run argv
    repeat with a in argv
        set a's contents to a as POSIX file as alias
    end repeat
    open argv
end run
