title: How to read from a zip file within zip file in Python?
body: <p>I have a file that I want to read that is itself zipped within a zip archive. For example, parent.zip contains child.zip, which contains child.txt. I am having trouble reading child.zip.  Can anyone correct my code?</p>
  
  <p>I assume that I need to create child.zip as a file-like object and then open it with a second instance of zipfile, but being new to python my zipfile.ZipFile(zfile.open(name)) is silly.  It raises a zipfile.BadZipfile: "File is not a zip file" on (independently validated) child.zip</p>
  
  <pre><code>import zipfile
  with zipfile.ZipFile("parent.zip", "r") as zfile:
      for name in zfile.namelist():
          if re.search(r'\.zip$', name) is not None:
              # We have a zip within a zip
              with **zipfile.ZipFile(zfile.open(name))** as zfile2:
                      for name2 in zfile2.namelist():
                          # Now we can extract
                          logging.info( "Found internal internal file: " + name2)
                          print "Processing code goes here"
  </code></pre>
