Python递归文件夹读取

Python递归文件夹读取

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：

• root

  ：“经过”的当前路径

• subdirs

  ：

  root

  目录类型中的文件

• files

  ：目录以外的其他文件

  root

  （不在中

  subdirs

  ）

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 osimport syswalk_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).enpre('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 asf = open('filename', 'rb')try:    dosomething()finally:    f.close()
