title: Using 7zip with python to create a password protected file in a given path
body: <p>I'm having an error for what seems to be a permissions problem when trying to create a zip file in a specified folder <code>testfolder</code> -folder has the following permissions:
  drwxr-xr-x  193 nobody nobody
  When trying to launch the following command in python I get the following:</p>
  
  <p><code>p= subprocess.Popen(['7z','a','-pinfected','-y','/home/John/testfolder/yada.zip'] + ['test.txt'],stdout=PIPE.subprocess,stderr=PIPE.subprocess)</code></p>
  
  <p><code>Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
    File "/usr/local/lib/python2.7/subprocess.py", line 710, in __init__
      errread, errwrite)
    File "/usr/local/lib/python2.7/subprocess.py", line 1327, in _execute_child
      raise child_exception
  OSError: [Errno 13] Permission denied</code></p>
  
  <p>Any idea what wrong with permissions?<br>
  I pretty new to it, my python runs from /usr/local/bin path</p>
