如何使用Python检测Windows中的闪存驱动器插件？

发布于 2024-08-16 00:29:54 字数 197 浏览 6 评论 0原文

我想让我的 Windows 计算机在检测到已插入具有特定名称（例如“我的驱动器”）的闪存驱动器时运行 Python 脚本。

我怎样才能实现这一点？

我应该在 Windows 中使用某些工具还是有办法编写另一个 Python 脚本来在插入闪存驱动器后立即检测它是否存在？（如果脚本在计算机上，我会更喜欢它。）

（我是编程新手..）

基于“CD”方法，如果您的脚本枚举了驱动器列表，等待 Windows 分配驱动器号几秒钟，然后重新枚举该列表，会怎么样？ python 集可以告诉你发生了什么变化，不是吗？以下对我有用：

# building on above and http://stackoverflow.com/questions/827371/is-there-a-way-to-list-all-the-available-drive-letters-in-python
import string
from ctypes import windll
import time
import os

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__':
    before = set(get_drives())
    pause = raw_input("Please insert the USB device, then press ENTER")
    print ('Please wait...')
    time.sleep(5)
    after = set(get_drives())
    drives = after - before
    delta = len(drives)

    if (delta):
        for drive in drives:
            if os.system("cd " + drive + ":") == 0:
                newly_mounted = drive
                print "There were %d drives added: %s. Newly mounted drive letter is %s" % (delta, drives, newly_mounted)
    else:
        print "Sorry, I couldn't find any newly mounted drives."

Building on the "CD" approach, what if your script enumerated the list of drives, waited a few seconds for Windows to assign the drive letter, then re-enumerated the list? A python set could tell you what changed, no? The following worked for me:

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


if __name__ == '__main__':
    before = set(get_drives())
    pause = raw_input("Please insert the USB device, then press ENTER")
    print ('Please wait...')
    time.sleep(5)
    after = set(get_drives())
    drives = after - before
    delta = len(drives)

    if (delta):
        for drive in drives:
            if os.system("cd " + drive + ":") == 0:
                newly_mounted = drive
                print "There were %d drives added: %s. Newly mounted drive letter is %s" % (delta, drives, newly_mounted)
    else:
        print "Sorry, I couldn't find any newly mounted drives."

虽然您可以使用“inpectorG4dget”建议的类似方法，但这会非常低效。

为此，您需要使用 Win API。此页面可能对您有用：链接

好吧，如果您使用的是 Linux 发行版，那么 SO 上的这个问题就会有答案。

我可以为你的问题想出一个迂回（不优雅）的解决方案，但至少它会起作用。

每次将闪存驱动器插入 USB 端口时，Windows 操作系统都会为其分配一个驱动器号。为了讨论的目的，我们将该字母称为“F”。

此代码查看我们是否可以 cd 进入 f:\。如果可以 cd 到 f:\，那么我们可以得出结论，“F”已被分配为驱动器号，并且假设您的闪存驱动器始终被分配给“F”，我们可以得出结论，您的闪存驱动器已插入。

import os
def isPluggedIn(driveLetter):
    if os.system("cd " +driveLetter +":") == 0: return True
    else: return False

Well, if you're on a Linux distribution, then this question on SO would have the answer.

I can think of a round-about (not elegant) solution for your problem, but at the very least it would WORK.

Every time you insert your flash drive into a USB port, the Windows OS assigns a drive letter to it. For the purposes of this discussion, let's call that letter 'F'.

This code looks to see if we can cd into f:\. If it is possible to cd into f:\, then we can conclude that 'F' has been allocated as a drive letter, and under the assumption that your flash drive always gets assigned to 'F', we can conclude that your flash drive has been plugged in.

import os
def isPluggedIn(driveLetter):
    if os.system("cd " +driveLetter +":") == 0: return True
    else: return False
