确保您了解以下三个返回值os.walk：
for root, subdirs, files in os.walk(rootdir):
具有以下含义：
并且请使用os.path.join而不是用斜杠连接！您的问题是filePath = rootdir + '/' + file-您必须串联当前的“移动”文件夹，而不是最顶层的文件夹。所以一定是filePath = os.path.join(root, file)。顺便说一句，“文件”是内置的，因此通常不将其用作变量名。
另一个问题是您的循环，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')
如果您不知道，则with文件声明是一种简写形式：
with open('filename', 'rb') as f:
dosomething()
# is effectively the same as
f = open('filename', 'rb')
try:
dosomething()
finally:
f.close()
