Using Windows’ WMI library, how can I eject CD rom mounted in a specific CD/DVD drive?

I am asking for sources from WMI docs or examples since I am using wmi.py library on Python.

It would be great if solution satisfies Windows computer newer than Windows 2000 and having multi CD-ROMs. (i.e. I have D: F: drives and both are CD-ROM drives. I might want to eject cd in F: specifically.)

Searched on the net but could not find anything relevant. The last solution must be having 3rd party binaries and executing from the shell.

    You can use ctypes.

    import ctypes

ctypes.windll.WINMM.mciSendStringW(u"set cdaudio door open", None, 0, None)

    UPDATE:

    If you have more that one drive, you can use to open command to initialize a specific device before calling the function above. For example (not tested).

    ctypes.windll.WINMM.mciSendStringW(u"open D: type cdaudio alias d_drive", None, 0, None)
ctypes.windll.WINMM.mciSendStringW(u"set d_drive door open", None, 0, None)

    Also, see the documentation on how to check return values
