在帶有python的Mac OS上如何僅列出可寫卷？換句話說，在 /Volumes 檔案夾中，我只想列出（磁區和筆式驅動器）rw 我不想列出 CDROM 驅動器或安裝的 ISO 映像。
在 linux 中有檔案“/proc/mounts”，它顯示已安裝的驅動器以及磁區型別和安裝選項，在 mac OS 中是否有類似的東西？在 linux 中，我是這樣使用的：
#!/usr/bin/env python3
# -*- coding: UTF-8 -*-
from pathlib import Path
import getpass
def get_lst_writable_linux_disks():
this_user = getpass.getuser()
lst_available_linux_disks = [str(Path.home())]
with open('/proc/mounts','r') as f:
data = f.readlines()
for line in data:
item = line.split(' ')
mount_point = item[1]
fs_type = item[2]
options = item[3]
if mount_point.startswith('/mnt') or (mount_point.startswith(f'/media/{this_user}') and fs_type != 'vfat' and 'rw' in options):
lst_available_linux_disks.append(mount_point)
return lst_available_linux_disks
print(get_lst_writable_linux_disks())
我如何在 Mac OS 上做同樣的事情？

對于比決議 的人類可讀輸出更防彈的方法diskutil info -all，您可以執行以下操作...（我不太喜歡 Apple 的 XML plist 格式；您會認為有更好的方法來表示 dict比平面鍵值鍵值-...結構...）
import subprocess
import xml.etree.ElementTree as ET
from typing import Tuple, List, Dict
def plist_dict_to_dict(node: ET.Element) -> Dict[str, ET.Element]:
assert node.tag == "dict"
dct = {}
current_key = None
for i, el in enumerate(node):
if i % 2 == 0:
assert el.tag == "key"
current_key = el.text
else:
assert current_key
dct[current_key] = el
return dct
def get_volume_names() -> List[str]:
command = ["/usr/sbin/diskutil", "list", "-plist"]
volumes_xml = ET.fromstring(subprocess.check_output(command, encoding="utf-8"))
volumes_info = plist_dict_to_dict(volumes_xml.find("dict"))
vfd_array = volumes_info["VolumesFromDisks"]
assert vfd_array.tag == "array"
return [v.text for v in vfd_array.findall("string")]
def get_volume_info(volume_name: str) -> Dict[str, ET.Element]:
command = ["/usr/sbin/diskutil", "info", "-plist", volume_name]
vol_info_xml = ET.fromstring(subprocess.check_output(command, encoding="utf-8"))
return plist_dict_to_dict(vol_info_xml.find("dict"))
def get_volume_flags(volume_name: str) -> Dict[str, bool]:
vol_info = get_volume_info(volume_name)
flags = {}
for key, value in vol_info.items():
if value.tag in ("true", "false"):
flags[key] = value.tag == "true"
return flags
if __name__ == "__main__":
for volume_name in get_volume_names():
print(volume_name, ":", get_volume_flags(volume_name))
在我的機器上，這會列印出來

所以除了“可寫”之外，您可能還想看看“內部”......
