title: Python 2.7 to 3.5 unzip error
body: <p>I am trying to update a script from 2.7 to 3.5. I keep getting an error with the following:</p>
  
  <pre><code>def _openScure(self, new_image):
      return os.system("unzip " + new_image)
  </code></pre>
  
  <p>The issue is with unzip in python 3.5 what should I replace it with?</p>
  
  <p>The error says:</p>
  
  <pre><code>'unzip' is not recognized as an internal or external command.
  </code></pre>
  
  <p>I have tried the following:</p>
  
  <pre><code>import zipfile
  
  with zipfile.ZipFile("name.zip", "r") as zip_ref:
      zip_ref . extractall (".")
  </code></pre>
  
  <p>Running win7 python 3.5.</p>
  
  <p>Here is a link to the entire script I am trying to update to 3.5. The issue I am having is with line 17. Any thoughts?</p>
