Surely there is some kind of abstraction that allows for this?

This is essentially the command

cmd = self._ghostscriptPath + 'gswin32c -q -dNOPAUSE -dBATCH -sDEVICE=tiffg4        -r196X204 -sPAPERSIZE=a4 -sOutputFile='' + tifDest + ' ' + pdfSource + '''  os.popen(cmd)

this way looks really dirty to me, there must be some pythonic way

  1. Use subprocess, it superseeds os.popen, though it is not much more of an abstraction:

    from subprocess import Popen, PIPE output = Popen(['mycmd', 'myarg'], stdout=PIPE).communicate()[0]  #this is how I'd mangle the arguments together output = Popen([     self._ghostscriptPath,     'gswin32c',    '-q',    '-dNOPAUSE',    '-dBATCH',    '-sDEVICE=tiffg4',    '-r196X204',    '-sPAPERSIZE=a4',    '-sOutputFile='%s %s'' % (tifDest, pdfSource), ], stdout=PIPE).communicate()[0]

    If you have only python 2.3 which has no subprocess module, you can still use os.popen

    os.popen(' '.join([     self._ghostscriptPath,     'gswin32c',    '-q',    '-dNOPAUSE',    '-dBATCH',    '-sDEVICE=tiffg4',    '-r196X204',    '-sPAPERSIZE=a4',    '-sOutputFile='%s %s'' % (tifDest, pdfSource), ]))
