python - 进入子文件夹(python)

Question

我写了一些东西来删除文件名中的特殊字符。但它只包含一个文件夹，而不包含它的子文件夹。我怎样才能在子文件夹和子子文件夹等中执行此操作？

import os
import re

def dir_list2(directory, *args):

    fileList = []
    content = os.listdir(directory)

    for file in content :

        dirfile = os.path.join(directory, file)
        if os.path.isfile(dirfile):
            if len(args) == 0:
                fileList.append(dirfile)
            else:
                if os.path.splitext(dirfile)[1][1:] in args:
                    fileList.append(dirfile)

        print "##################################################"

        print "Old filename:", file

        filename = file
        remove = re.compile("[^.a-zA-z0-9_]")
        output = remove.sub('_', filename)

        newfile = directory + "/" + output
        os.rename(dirfile, newfile)

        print "Corrected filename:", output
        #Removes Special Characters


    return fileList

if __name__ == '__main__':


    fileList = dir_list2('/path/')

Answer 1

尝试使用os.walk它允许您浏览文件夹及其文件和子文件夹等，而不是 os.listdir。

编辑您的代码，如下所示:

content = os.walk(directory)

for dirpath, dirnames, filenames in content:
    for file in filenames:
        dirfile = os.path.join(dirpath, file)

        # The rest of your code
