Question

或多或少在它上面说的：在Python中有一种（简单的）方法可以列出Windows系统中当前正在使用的所有驱动器号吗？

（我的google-fu似乎让我失望了。）

Enumerating all available drive letters in Windows（C ++ / Win32）

Answer 1

不使用任何外部库，如果这对您很重要：

import string
from ctypes import windll

def get_drives():
    drives = []
    bitmask = windll.kernel32.GetLogicalDrives()
    for letter in string.uppercase:
        if bitmask & 1:
            drives.append(letter)
        bitmask >>= 1

    return drives

if __name__ == '__main__':
    print get_drives()     # On my PC, this prints ['A', 'C', 'D', 'F', 'H']

Answer 2

import win32api

drives = win32api.GetLogicalDriveStrings()
drives = drives.split('\000')[:-1]
print drives

Answer 3

那些看起来更好的答案。这是我的hackish cruft

import os, re
re.findall(r"[A-Z]+:.*$",os.popen("mountvol /").read(),re.MULTILINE)

在RichieHindle的答案上稍微嗤之以鼻;它并不是真的更好，但你可以让窗户做出实际的字母表字母的工作

>>> import ctypes
>>> buff_size = ctypes.windll.kernel32.GetLogicalDriveStringsW(0,None)
>>> buff = ctypes.create_string_buffer(buff_size*2)
>>> ctypes.windll.kernel32.GetLogicalDriveStringsW(buff_size,buff)
8
>>> filter(None, buff.raw.decode('utf-16-le').split(u'\0'))
[u'C:\\', u'D:\\']

Answer 4

Microsoft Script Repository包括this recipe，这可能有所帮助。我没有Windows机器来测试它，所以我不确定你是否想要“名称”，“系统名称”，“卷名”或其他东西。

import win32com.client 
strComputer = "." 
objWMIService = win32com.client.Dispatch("WbemScripting.SWbemLocator") 
objSWbemServices = objWMIService.ConnectServer(strComputer,"root\cimv2") 
colItems = objSWbemServices.ExecQuery("Select * from Win32_LogicalDisk") 
for objItem in colItems: 
    print "Access: ", objItem.Access 
    print "Availability: ", objItem.Availability 
    print "Block Size: ", objItem.BlockSize 
    print "Caption: ", objItem.Caption 
    print "Compressed: ", objItem.Compressed 
    print "Config Manager Error Code: ", objItem.ConfigManagerErrorCode 
    print "Config Manager User Config: ", objItem.ConfigManagerUserConfig 
    print "Creation Class Name: ", objItem.CreationClassName 
    print "Description: ", objItem.Description 
    print "Device ID: ", objItem.DeviceID 
    print "Drive Type: ", objItem.DriveType 
    print "Error Cleared: ", objItem.ErrorCleared 
    print "Error Description: ", objItem.ErrorDescription 
    print "Error Methodology: ", objItem.ErrorMethodology 
    print "File System: ", objItem.FileSystem 
    print "Free Space: ", objItem.FreeSpace 
    print "Install Date: ", objItem.InstallDate 
    print "Last Error Code: ", objItem.LastErrorCode 
    print "Maximum Component Length: ", objItem.MaximumComponentLength 
    print "Media Type: ", objItem.MediaType 
    print "Name: ", objItem.Name 
    print "Number Of Blocks: ", objItem.NumberOfBlocks 
    print "PNP Device ID: ", objItem.PNPDeviceID 
    z = objItem.PowerManagementCapabilities 
    if z is None: 
        a = 1 
    else: 
        for x in z: 
            print "Power Management Capabilities: ", x 
    print "Power Management Supported: ", objItem.PowerManagementSupported 
    print "Provider Name: ", objItem.ProviderName 
    print "Purpose: ", objItem.Purpose 
    print "Quotas Disabled: ", objItem.QuotasDisabled 
    print "Quotas Incomplete: ", objItem.QuotasIncomplete 
    print "Quotas Rebuilding: ", objItem.QuotasRebuilding 
    print "Size: ", objItem.Size 
    print "Status: ", objItem.Status 
    print "Status Info: ", objItem.StatusInfo 
    print "Supports Disk Quotas: ", objItem.SupportsDiskQuotas 
    print "Supports File-Based Compression: ", objItem.SupportsFileBasedCompression 
    print "System Creation Class Name: ", objItem.SystemCreationClassName 
    print "System Name: ", objItem.SystemName 
    print "Volume Dirty: ", objItem.VolumeDirty 
    print "Volume Name: ", objItem.VolumeName 
    print "Volume Serial Number: ", objItem.VolumeSerialNumber

Answer 5

在Google上找到此解决方案，稍有修改。貌似漂亮的pythonic，不需要任何“异国情调”的进口

import os, string
available_drives = ['%s:' % d for d in string.ascii_uppercase if os.path.exists('%s:' % d)]

Answer 6

我写了这段代码：

import os
drives = [ chr(x) + ":" for x in range(65,90) if os.path.exists(chr(x) + ":") ]

它基于@ Barmaley的回答，但具有不使用string的优势模块，以防您不想使用它。它也适用于我的系统，不像@ SingleNegationElimination的答案。

Answer 7

基于@RichieHindle的更佳解决方案

def get_drives():
    drives = []
    bitmask = windll.kernel32.GetLogicalDrives()
    letter = ord('A')
    while bitmask > 0:
        if bitmask & 1:
            drives.append(chr(letter) + ':\\')
        bitmask >>= 1
        letter += 1

    return drives

Answer 8

在Windows上，您可以执行os.popen

import os
print os.popen("fsutil fsinfo drives").readlines()

Answer 9

这是我的更高性能方法（可能更高）：

>>> from string import ascii_uppercase
>>> reverse_alphabet = ascii_uppercase[::-1]
>>> from ctypes import windll # Windows only
>>> GLD = windll.kernel32.GetLogicalDisk
>>> drives = ['%s:/'%reverse_alphabet[i] for i,v in enumerate(bin(GLD())[2:]) if v=='1']

没有人真正使用python的表演性功能......

是的，我没有遵循Windows标准路径约定（'\\'）...
在使用python的所有这些年里，我在使用任何路径的'/'方面没有任何问题，并且在我的程序中使它成为标准。

Answer 10

如果您只想列出光盘上的驱动器而不是列出的网络驱动器，那么这是另一个很棒的解决方案。如果要按不同的属性进行过滤，只需打印drps。

import psutil
drps = psutil.disk_partitions()
drives = [dp.device for dp in drps if dp.fstype == 'NTFS']

Answer 11

此代码将返回驱动器名称和字母的列表，例如：

['Gateway（C :)'，'EOS_DIGITAL（L :)'，'Music Archive（O：）']

它仅使用标准库。它基于我在上面发现的一些想法。如果磁盘驱动器为空，则windll.kernel32.GetVolumeInformationW（）返回0，例如，没有磁盘的CD ROM。此代码未列出这些空驱动器。

这两行记录了所有驱动器的字母：

bitmask = (bin(windll.kernel32.GetLogicalDrives())[2:])[::-1]  # strip off leading 0b and reverse
drive_letters = [ascii_uppercase[i] + ':/' for i, v in enumerate(bitmask) if v == '1']

这是完整的例程：

from ctypes import windll, create_unicode_buffer, c_wchar_p, sizeof
from string import ascii_uppercase

def get_win_drive_names():
    volumeNameBuffer = create_unicode_buffer(1024)
    fileSystemNameBuffer = create_unicode_buffer(1024)
    serial_number = None
    max_component_length = None
    file_system_flags = None
    drive_names = []
    #  Get the drive letters, then use the letters to get the drive names
    bitmask = (bin(windll.kernel32.GetLogicalDrives())[2:])[::-1]  # strip off leading 0b and reverse
    drive_letters = [ascii_uppercase[i] + ':/' for i, v in enumerate(bitmask) if v == '1']

    for d in drive_letters:
        rc = windll.kernel32.GetVolumeInformationW(c_wchar_p(d), volumeNameBuffer, sizeof(volumeNameBuffer),
                                                   serial_number, max_component_length, file_system_flags,
                                                   fileSystemNameBuffer, sizeof(fileSystemNameBuffer))
        if rc:
            drive_names.append(f'{volumeNameBuffer.value}({d[:2]})')  # disk_name(C:)
    return drive_names

Answer 12

作为类似任务的一部分，我还需要获取免费的驱动器号。我决定要收到最高的信件。我首先用惯用语写出来，然后把它碾成1个衬里，看看它是否仍然有意义。正如列表理解一样令人敬畏，我喜欢这样设置：unused=set(alphabet)-set(used)而不是必须unused = [a for a in aphabet if a not in used]。很酷的东西！

def get_used_drive_letters():
    drives = win32api.GetLogicalDriveStrings()
    drives = drives.split('\000')[:-1]
    letters = [d[0] for d in drives]
    return letters

def get_unused_drive_letters():
    alphabet = map(chr, range(ord('A'), ord('Z')+1))
    used = get_used_drive_letters()
    unused = list(set(alphabet)-set(used))
    return unused

def get_highest_unused_drive_letter():
    unused = get_unused_drive_letters()
    highest = list(reversed(sorted(unused)))[0]
    return highest

一个班轮：

def get_drive():
    highest = sorted(list(set(map(chr, range(ord('A'), ord('Z')+1))) -
                          set(win32api.GetLogicalDriveStrings().split(':\\\000')[:-1])))[-1]

我还使用map / range / ord / chr选择使用字符串的字母表，因为部分字符串已被弃用。

Answer 13

由于我没有在我的笔记本电脑领域安装win32api，我使用wmic来解决这个问题：

import subprocess
import string

#define alphabet
alphabet = []
for i in string.ascii_uppercase:
    alphabet.append(i + ':')

#get letters that are mounted somewhere
mounted_letters = subprocess.Popen("wmic logicaldisk get name", shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
#erase mounted letters from alphabet in nested loop
for line in mounted_letters.stdout.readlines():
    if "Name" in line:
        continue
    for letter in alphabet:
        if letter in line:
            print 'Deleting letter %s from free alphabet %s' % letter
            alphabet.pop(alphabet.index(letter))

print alphabet

或者你可以从这两个列表中获得差异，就像这个更简单的解决方案（在启动wmic子进程作为mounted_letters之后）：

#get output to list
mounted_letters_list = []
for line in mounted_letters.stdout.readlines():
    if "Name" in line:
        continue
    mounted_letters_list.append(line.strip())

rest = list(set(alphabet) - set(mounted_letters_list))
rest.sort()
print rest

两种解决方案同样快速，但我认为设置列表出于某种原因更好，对吧？

Answer 14

如果您不想担心跨平台问题，包括跨越Pypy等python平台的问题，并且希望在运行时更新驱动器时使用性能良好的东西：

>>> from os.path import exists
>>> from sys import platform
>>> drives = ''.join( l for l in 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' if exists('%s:/'%l) ) if platform=='win32' else ''
>>> drives
'CZ'

这是我对此代码的性能测试：

4000 iterations; threshold of min + 250ns:
__________________________________________________________________________________________________________code___|_______min______|_______max______|_______avg______|_efficiency

Answer 15

这是一个简单的版本，没有安装任何其他模块或功能。

>>> import os
>>> ['%s:' % d for d in 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' if os.path.exists('%s:' % d)]
['C:', 'D:']

Answer 16

这将有助于在Windows操作系统中找到有效的驱动器

import os
import string
drive = string.ascii_uppercase
valid_drives = []
for each_drive in drive:
    if os.path.exist(each_drive+":\\"):
       print(each_drive)
       valid_drives.append(each_drive+":\\")
print(valid_drives)

输出将是

C
D
E
['C:\\','D:\\','E:\\']

Answer 17

如果只需要每个驱动器的字母，则可以：

from win32.win32api import GetLogicalDriveStrings


drives = [drive for drive in GetLogicalDriveStrings()[0]]

有没有办法列出python中所有可用的驱动器号？
