Eject a Removable USB drive

def do_magic():
    from staples import easy_button
    result = easy_button.press()
    return result

:) In all seriousness that code did the trick but only after a short delay. I noticed when I first ran it, there was no effect. But when I ran it interactively, it succeeded.

Is there any way to check that the drive is still showing up in explorer and then re-run the code? Something like:

while drive_exists:
	shell.SHChangeNotify(shellcon.SHCNE_DRIVEREMOVED, shellcon.SHCNF_PATH, "F:\\")


Right now I've got:

time.sleep(1)
shell.SHChangeNotify(shellcon.SHCNE_DRIVEREMOVED, shellcon.SHCNF_PATH, "F:\\")


Thanks for your help!
