title: get file list of files contained in a zip file
body: <p>I have a zip archive: <code>my_zip.zip</code>. <strong>Inside it is one txt file, the name of which I do not know.</strong> I was taking a look at Python's <code>zipfile</code> module ( <a href="http://docs.python.org/library/zipfile.html">http://docs.python.org/library/zipfile.html</a> ), but couldn't make too much sense of what I'm trying to do.</p>
  
  <p>How would I do the equivalent of 'double-clicking' the zip file to get the txt file and then use the txt file so I can do:</p>
  
  <pre><code>&gt;&gt;&gt; f = open('my_txt_file.txt','r')
  &gt;&gt;&gt; contents = f.read()
  </code></pre>
