title: Mimic 7zip with python
body: <p>I am using Python 3.6, and currently I subprocess out to my 7zip program to get the compression I need.</p>
  
  <p><code>subprocess.call('7z a -t7z -ms=off {0} *'.format(filename))</code></p>
  
  <p>I know the zipfile class has ‘ZIP_LZMA’ compression, but the application I am passing this too says the output file isn’t correct.  So what else do I have to add to the ZipFile class to make it mimic the above command?</p>
