call osfmount with python script

Thanks. I figured it was me, but I thought I would ask.

Here is my test code that works...

import subprocess, re
from time import sleep


image_file=r'G:\TestImages\myimage.E01'
cmd_line=r'osfmount -a -t file -f ' +  image_file + ' -m #:'
try:
  ret_string = subprocess.check_output(cmd_line, stderr=subprocess.STDOUT, shell=True)


  #Get the drive letter
  if len(ret_string) > 0:
    ret_string=str(ret_string)
    m = re.search(r'[a-zA-Z]:\s', ret_string)
    drive_letter=m.group(0)
    print('Image was mounted on {0}'.format(drive_letter))
    
    #unmount the image
    sleep(10)
    cmd_line=r'osfmount -d -m ' + drive_letter
    retcode=subprocess.check_output(cmd_line, stderr=subprocess.STDOUT, shell=True)
    print ('Image on {0} was unmounted'.format(drive_letter))
    
  else:
    print('Image was not mounted')
    
except OSError as e:
  print('Execution failed: {0}'.format(e))


except subprocess.CalledProcessError as e:
  print (e.output)

While I have done programming in maybe a dozen different languages, Python isn't one of them.

If, as you say, you have it working from the command line, then there is probably some silly syntax error in your Python script.

I'm attempting to right a python script to mount e01 files using osfmount. The command line I'm using works in the terminal, but not in my script. Is there something special I need to do?

I'm using python 3.3 and subprocess.check_output command. The gui pops up instead of mounting the image.

Pertinent lines of code I'm using:

image_file=r'G:\TestImages\myimage.E01'
cmd_line='osfmount -a -t file -f  ' + image_file + ' -m #:'
ret_string = subprocess.check_output(cmd_line)

I'm fairly new at python, but I think this should work.
