我的 Python 脚本与 os.rmdir (dirs[:]) & os.remove (files[:]) 与特定排除部分工作，但是它确实删除了一点点...

例如 /media/ 文件夹 (dir) 也被删除，但我确实尝试排除它，这是我的示例代码：

def rejuvXvbmc():
    yes_pressed=Common.message_yes_no("[COLOR dodgerblue]"+AddonTitle+"[/COLOR] [COLOR red][B]- Reset![/B][/COLOR]",'Wilt u uw XvBMC \'build\' volledig opschonen (wipe) en Kodi Krypton [B]leeg[/B] her-configureren?','[COLOR dimgray]Please confirm that you wish you wipe clean your current configuration and reconfigure Kodi.[/COLOR]')
    if yes_pressed:
        dp.create("[COLOR white]"+AddonTitle+"[/COLOR] [COLOR red][B]- Reset![/B][/COLOR]",'Snelle XvBMC Krypton reset, even geduld...',' ', '[COLOR dimgray](Quick XvBMC Krypton reset, please wait...)[/COLOR]')
        profileDir=xbmcaddon.Addon(id=addon_id).getAddonInfo('path'); profileDir=xbmc.translatePath(profileDir);
        xbmcPath=os.path.join(profileDir,"..",".."); xbmcPath=os.path.abspath(xbmcPath); Common.log("rejuvXvbmc.main_XvBMC: xbmcPath="+xbmcPath);

这里我排除了 de\media\ 文件夹：

if keep_xvbmc: 
    dir_exclude     = ('addon_data','media',)+dir_exclude

我认为问题出在这部分？？？

for file_name in files:

这个可能删除太多，所以文件夹 /media/ 也完全为空，这就是它被删除的原因？ Common.REMOVE_EMPTY_FOLDERS() 仅删除完全 empty 剩余部分。

我应该以某种方式将 dir_exclude 集成到这里吗？（在/下 for file_name in files:），我正在尝试，但我似乎无法弄清楚 :'(

我也试过了，现在 /media/ 文件夹没有弄乱，但是现在太多文件夹仍然存在：

        for file_name in files:
            if not any(root.find(f) for f in dir_exclude):
                try:
                    dp.update(33,'','***Cleaning files...')
                    os.remove(os.path.join(root,file_name))
                   #Common.log(os.path.join(root,file_name))
                except Exception as e: Common.log("rejuvXvbmc.file_name: User files partially removed - " + str(e))

L-- 如你所见，我在下一行添加了这一行：

if not any(root.find(f) for f in dir_exclude):

当我将 'media' 添加到 sub_dir_exclude 时，所有带有 'media' 的文件夹都会被跳过，这也不是我想要的，只有 xbmcPath 中的 'media' 文件夹必须保留（从删除中跳过）。

xbmcPath 是我的根/开始文件夹，它“有点像”：xbmc.translatePath('special://home/') ，从这一点开始，我执行 os.walk(xbmcPath,topdown=True)。

【问题讨论】：

那里有很多无用的代码。请查看[SO]: How to create a Minimal, Complete, and Verifiable example (mcve)。 【参考方案1】：

没关系，这成功了：

if len(bestanden) > 1:
    vh = dialog.select('Selecteer bestand om te downloaden', bestanden)
    if vh == -1:
        return
else:
    vh = 0
