我正在尝试从Python传递一个文件路径到n Applescript，不知道如何实现它。下面的代码显示了正在运行的Applescript代码，该代码提示打开文件或文件，然后重新分配音频通道，保存和关闭。我没有提示输入文件，而是想将文件路径传递给osascript Applescript，我已经设置了args，但不知道如何让它工作。

找到答案。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
答案 1 :(得分：0)
根据osascript的手册页，参数将传递给运行处理程序。
所以就像你“打开aa”一样，你会“运行文件路径”，然后在“选择文件”中使用它。
on run filepath
open (choose file with prompt ("Choose movie file(s)") ¬
with multiple selections allowed default location filepath)
end run
从字面上看，这应该是你必须做出的唯一改变。
