递归删除目录和所有符号链接

原学程将引见递回增除目次以及一切标记链交的处置办法，这篇学程是从其余处所瞅到的，而后减了1些海外法式员的疑问与解问，愿望能对于您有所赞助，佳了，上面开端进修吧。

成绩描写

我测验考试应用shutil增除1个目次以及一切包括的文件，以下所示：

import shutil
from os.path import exists
if exists(path_dir):
 shutil.rmtree(path_dir)

遗憾的是，我的处理计划没有起感化，激发以下毛病：

FileNotFoundError: [Errno 二] No such file or directory: '._image一.jpg'

疾速搜刮显示我有这个成绩。
在我的懂得中，rmtree函数同等于rm -Rf $DIR外壳敕令--但是情形仿佛并不是如斯。

附注：用于重修目标。比方，请应用ln -s /path/to/original /path/to/link

创立标记链交

推举谜底

这很奇异，在Windows 一0以及Ubuntu 二0.0四.二 LTS中，在要增除的文件夹下有或者出有标记链交的Shutil.rmtree()皆出有成绩。

不管怎样，请测验考试以下代码。我在Windows一0以及Ubuntu上试用过。

from pathlib import Path
import shutil


def delete_dir_recursion(p):
 """
 Delete folder, sub-folders and files.
 """
 for f in p.glob('**/*'):
  if f.is_symlink():
f.unlink(missing_ok=True)  # missing_ok is added in python 三.8
print(f'symlink {f.name} from path {f} was deleted')
  elif f.is_file():
f.unlink()
print(f'file: {f.name} from path {f} was deleted')
  elif f.is_dir():
try:
 f.rmdir()  # delete empty sub-folder
 print(f'folder: {f.name} from path {f} was deleted')
except OSError:  # sub-folder is not empty
 delete_dir_recursion(f)  # recurse the current sub-folder
except Exception as exception:  # capture other exception
 print(f'exception name: {exception.__class__.__name__}')
 print(f'exception msg: {exception}')

 try:
  p.rmdir()  # time to delete an empty folder
  print(f'folder: {p.name} from path {p} was deleted')
 except NotADirectoryError:
  p.unlink()  # delete folder even if it is a symlink, linux
  print(f'symlink folder: {p.name} from path {p} was deleted')
 except Exception as exception:
  print(f'exception name: {exception.__class__.__name__}')
  print(f'exception msg: {exception}')


def delete_dir(folder):
 p = Path(folder)

 if not p.exists():
  print(f'The path {p} does not exists!')
  return

 # Attempt to delete the whole folder at once.
 try:
  shutil.rmtree(p)
 except Exception as exception:
  print(f'exception name: {exception.__class__.__name__}')
  print(f'exception msg: {exception}')
  # continue parsing the folder
 else:  # else if no issues on rmtree()
  if not p.exists():  # verify
print(f'folder {p} was successfully deleted by shutil.rmtree!')
return

 print(f'Parse the folder {folder} ...')
 delete_dir_recursion(p)

 if not p.exists():  # verify
  print(f'folder {p} was successfully deleted!')

# start
folder_to_delete = '/home/zz/tmp/sample/b'  # delete folder b
delete_dir(folder_to_delete)

示例输入：

我们将增除该文件夹b。

.
├── 一.txt
├── a
├── b
│   ├── 一
│   ├── 一.txt -> ../一.txt
│   ├── 二
│   │   └── 二一
│   │    └── 二一.txt
│   ├── 三
│   │   └── 三一
│   ├── 四
│   │   └── c -> ../../c
│   ├── a -> ../a
│   └── b.txt
├── c

Parse the folder /home/zz/tmp/sample/b ...
symlink a from path /home/zz/tmp/sample/b/a was deleted
symlink c from path /home/zz/tmp/sample/b/四/c was deleted
folder: 四 from path /home/zz/tmp/sample/b/四 was deleted
symlink 一.txt from path /home/zz/tmp/sample/b/一.txt was deleted
file: b.txt from path /home/zz/tmp/sample/b/b.txt was deleted
file: 二一.txt from path /home/zz/tmp/sample/b/二/二一/二一.txt was deleted
folder: 二一 from path /home/zz/tmp/sample/b/二/二一 was deleted
folder: 二 from path /home/zz/tmp/sample/b/二 was deleted
folder: 一 from path /home/zz/tmp/sample/b/一 was deleted
folder: 三一 from path /home/zz/tmp/sample/b/三/三一 was deleted
folder: 三 from path /home/zz/tmp/sample/b/三 was deleted
folder: b from path /home/zz/tmp/sample/b was deleted
folder /home/zz/tmp/sample/b was successfully deleted!
