將批處理命令轉換為python

Question

我正在嘗試將 .bat 文件轉換為 python，幾乎一切正常，只有壓縮部分不起作用，我指出了“rar.exe”的標志和路徑，但它在蟒蛇版本。 我需要糾正什么才能擁有與“.bat”版本相同的行為？

謝謝

bat版本.bat

@echo off

setlocal EnableDelayedExpansion
set "FolderBaseName=myFolder"

set "DropBoxFolder=D:\Tests\3.asc\MyDropBox"
set "BaseOutputFolder=D:\Tests\3.asc\TEMP"

for %%I in (*.png) do (

    set "slaveName=%%~nI"
    set "slaveName=!slaveName:~6!
    set "OutputFolder=%BaseOutputFolder%_!slaveName!"

    echo !slaveName!   
    md "!OutputFolder!" 2>nul

    for %%J in (*.mp4*) do (      
        ffmpeg -i "%%~fJ" -i "%%~fI" -filter_complex overlay "!OutputFolder!\%%~nJ.mp4"
    )


    "C:\Program Files\WinRAR\rar.exe" a -cfg- -ep1 -inul -m5 "%DropBoxFolder%\%FolderBaseName%_!slaveName!" "!slaveName:~6!\*"
    rd /S /Q "!OutputFolder!"
)
pause

            # this doesnt work, and also I only want it to happen after the conversion above has finished

processVideos()

Answer 1

您需要對要創建的Popen對象使用communicate方法。

blah = Popen(...)
blah.communicate()

這也將阻塞，直到完成為止，之后您可以啟動第二個命令。

Answer 2

import subprocess
blah = subprocess.Popen('aaa.bat', stderr=subprocess.STDOUT, stdout=subprocess.PIPE)
blah.communicate()
