python os.listdir()显示受保护的文件

所以,我正在努力让自己成为一个Python脚本,它遍历所选的音乐文件夹并告诉用户特定专辑是否没有专辑封面。它基本上遍历所有文件并检查if file[-4:] in (".jpg",".bmp",".png"),如果为真,它找到了一个图片文件。为了说清楚,我的文件夹的结构是:

  • 音乐文件夹
    • 北极猴子
      • Humbug(2009)
      • 吮吸它,然后看(2011)
    • 吗啡
      • 治愈疼痛(1993)

..等等。我正在测试脚本以查找我的Arctic Monkeys目录中是否有丢失的封面,我的脚本通过“Humbug(2009)”文件夹找到了AlbumArtSmall.jpg which doesn't show up in the command prompt所以我尝试了“显示隐藏文件/文件夹“仍然没有。但是,the files show up once I uncheck "Hide protected operating system files",所以这有点奇怪。

我的问题是 - 如何告诉Python跳过搜索隐藏/受保护的文件? 我检查了How to ignore hidden files using os.listdir()?,但我找到的解决方案仅适用于以“。”开头的文件,而这不是我需要的。

干杯!


编辑 - 所以这是代码:

import os

def findCover(path, band, album):
    print os.path.join(path, band, album)
    coverFound = False

    for mFile in os.listdir(os.path.join(path, band, album)):
        if mFile[-4:] in (".jpg",".bmp",".png"):
            print "Cover file found - %s." % mFile
            coverFound = True
            return coverFound

musicFolder = "E:\Music"   #for example
noCovers = []

for band in os.listdir(musicFolder):    #iterate over bands inside the music folder
    if band[0:] == "Arctic Monkeys":    #only Arctic Monkeys
        print band
        bandFolder = os.path.join(musicFolder, band)
        for album in os.listdir(bandFolder):
            if os.path.isdir(os.path.join(bandFolder,album)):
                if findCover(musicFolder, band, album): #if cover found
                    pass                                #do nothing
                else:
                    print "Cover not found"
                    noCovers.append(band+" - "+album)   #append to list
            else:                       #if bandFolder is not actually a folder
                pass
        print ""

您可以使用pywin32 module,并手动测试FILE_ATTRIBUTE_HIDDEN或任意数量的属性

FILE_ATTRIBUTE_ARCHIVE              = 32
FILE_ATTRIBUTE_ATOMIC_WRITE         = 512
FILE_ATTRIBUTE_COMPRESSED           = 2048
FILE_ATTRIBUTE_DEVICE               = 64
FILE_ATTRIBUTE_DIRECTORY            = 16
FILE_ATTRIBUTE_ENCRYPTED            = 16384
FILE_ATTRIBUTE_HIDDEN               = 2
FILE_ATTRIBUTE_NORMAL               = 128
FILE_ATTRIBUTE_NOT_CONTENT_INDEXED  = 8192
FILE_ATTRIBUTE_OFFLINE              = 4096
FILE_ATTRIBUTE_READONLY             = 1
FILE_ATTRIBUTE_REPARSE_POINT        = 1024
FILE_ATTRIBUTE_SPARSE_FILE          = 512
FILE_ATTRIBUTE_SYSTEM               = 4
FILE_ATTRIBUTE_TEMPORARY            = 256
FILE_ATTRIBUTE_VIRTUAL              = 65536
FILE_ATTRIBUTE_XACTION_WRITE        = 1024
像这样:

import win32api, win32con

#test for a certain type of attribute
attribute = win32api.GetFileAttributes(filepath)
#The file attributes are bitflags, so you want to see if a given flag is 1.
# (AKA if it can fit inside the binary number or not) 
# 38 in binary is  100110 which means that 2, 4 and 32 are 'enabled', so we're checking for that
## Thanks to Nneoneo
if attribute & (win32con.FILE_ATTRIBUTE_HIDDEN | win32con.FILE_ATTRIBUTE_SYSTEM):
  raise Exception("hidden file") #or whatever

#or alter them
win32api.SetFileAttributes(filepath, win32con.FILE_ATTRIBUTE_NORMAL) #or FILE_ATTRIBUTE_HIDDEN

更改文件后,查看该文件夹,它将不再被隐藏。

或者,您可以尝试使用其文档hereos.stat函数,然后使用stat module进一步了解您正在查看的内容。
