Python: OS Independent list of available storage devices

Question

Is there a way go get a list of connected storage devices, like Cameras, SD cards and external Hard Drives, in Python?

Answer 1

The following should work for Linux and Windows. This will list ALL drives, not just externals!

import subprocess
import sys

#on windows
#Get the fixed drives
#wmic logicaldisk get name,description
if 'win' in sys.platform:
    drivelist = subprocess.Popen('wmic logicaldisk get name,description', shell=True, stdout=subprocess.PIPE)
    drivelisto, err = drivelist.communicate()
    driveLines = drivelisto.split('\n')
elif 'linux' in sys.platform:
     listdrives=subprocess.Popen('mount', shell=True, stdout=subprocess.PIPE)
     listdrivesout, err=listdrives.communicate()
     for idx,drive in enumerate(filter(None,listdrivesout)):
         listdrivesout[idx]=drive.split()[2]
# guess how it should be on mac os, similar to linux , the mount command should 
# work, but I can't verify it...
elif 'macosx' ...
     do the rest....

The above method for Linux is very crude, and will return drives like sys and procfs etc., if you want something more fine tuned, look into querying with python-dbus.
