python - 如何使用 Python 在 Windows 中检测闪存驱动器插件？

Question

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

我怎样才能做到这一点？

我应该在 Windows 中使用某种工具，还是可以编写另一个 Python 脚本来检测插入闪存驱动器后是否存在？ (如果脚本在计算机上，我会更喜欢它。)

(我是一个编程新手..)

在“CD”方法的基础上，如果您的脚本枚举驱动器列表，等待几秒钟让 Windows 分配驱动器号，然后重新枚举列表，会怎样？一个 python 集可以告诉你发生了什么变化，不是吗？以下对我有用:

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."
