确保你理解os.walk的三个返回值:

for root, subdirs, files in os.walk(rootdir):

具有以下含义:

root:被“遍历”的当前路径 subdirs:目录类型根目录下的文件 files:根目录下(不是subdirs目录下)的非directory类型的文件

请使用os.path.join而不是用斜杠连接!您的问题是filePath = rootdir + '/' + file -您必须连接当前“行走”的文件夹，而不是最上面的文件夹。filePath = os。path。加入(根、文件)。顺便说一句，“文件”是内置的，所以你通常不使用它作为变量名。

另一个问题是你的循环，应该是这样的，例如:

import os
import sys

walk_dir = sys.argv[1]

print('walk_dir = ' + walk_dir)

# If your current working directory may change during script execution, it's recommended to
# immediately convert program arguments to an absolute path. Then the variable root below will
# be an absolute path as well. Example:
# walk_dir = os.path.abspath(walk_dir)
print('walk_dir (absolute) = ' + os.path.abspath(walk_dir))

for root, subdirs, files in os.walk(walk_dir):
    print('--\nroot = ' + root)
    list_file_path = os.path.join(root, 'my-directory-list.txt')
    print('list_file_path = ' + list_file_path)

    with open(list_file_path, 'wb') as list_file:
        for subdir in subdirs:
            print('\t- subdirectory ' + subdir)

        for filename in files:
            file_path = os.path.join(root, filename)

            print('\t- file %s (full path: %s)' % (filename, file_path))

            with open(file_path, 'rb') as f:
                f_content = f.read()
                list_file.write(('The file %s contains:\n' % filename).encode('utf-8'))
                list_file.write(f_content)
                list_file.write(b'\n')

如果你不知道，文件的with语句是一种简写:

with open('filename', 'rb') as f:
    dosomething()

# is effectively the same as

f = open('filename', 'rb')
try:
    dosomething()
finally:
    f.close()

我认为问题在于你没有处理os的输出。正确的走路。

首先,改变:

filePath = rootdir + '/' + file

to:

filePath = root + '/' + file

Rootdir是固定的起始目录;Root是os.walk返回的目录。

其次，您不需要缩进您的文件处理循环，因为对每个子目录运行这个没有意义。您将获得每个子目录的根集。您不需要手动处理子目录，除非您想对目录本身做一些事情。

使用os.path.join()来构造你的路径-这样更整洁:

import os
import sys
rootdir = sys.argv[1]
for root, subFolders, files in os.walk(rootdir):
    for folder in subFolders:
        outfileName = os.path.join(root,folder,"py-outfile.txt")
        folderOut = open( outfileName, 'w' )
        print "outfileName is " + outfileName
        for file in files:
            filePath = os.path.join(root,file)
            toWrite = open( filePath).read()
            print "Writing '" + toWrite + "' to" + filePath
            folderOut.write( toWrite )
        folderOut.close()

在我看来，os.walk()有点太复杂和啰嗦了。你可以做接受的答案清洁:

all_files = [str(f) for f in pathlib.Path(dir_path).glob("**/*") if f.is_file()]

with open(outfile, 'wb') as fout:
    for f in all_files:
        with open(f, 'rb') as fin:
            fout.write(fin.read())
            fout.write(b'\n')

pathlib库非常适合处理文件。你可以在Path对象上做这样的递归glob。

from pathlib import Path

for elem in Path('/path/to/my/files').rglob('*.*'):
    print(elem)

如果你更喜欢(几乎)联机:

from pathlib import Path

lookuppath = '.' #use your path
filelist = [str(item) for item in Path(lookuppath).glob("**/*") if Path(item).is_file()]

在这种情况下，您将得到一个列表，其中仅包含递归位于lookppath下的所有文件的路径。 如果没有str()，你将得到PosixPath()添加到每个路径。
