title: Extract Google Drive zip from Google colab notebook
body: <p>I already have a zip of (2K images) dataset on a google drive. I have to use it in a ML training algorithm.
  Below Code extracts the content in a string format:</p>
  
  <pre><code>from pydrive.auth import GoogleAuth
  from pydrive.drive import GoogleDrive
  from google.colab import auth
  from oauth2client.client import GoogleCredentials
  import io
  import zipfile
  # Authenticate and create the PyDrive client.
  # This only needs to be done once per notebook.
  auth.authenticate_user()
  gauth = GoogleAuth()
  gauth.credentials = GoogleCredentials.get_application_default()
  drive = GoogleDrive(gauth)
  
  # Download a file based on its file ID.
  #
  # A file ID looks like: laggVyWshwcyP6kEI-y_W3P8D26sz
  file_id = '1T80o3Jh3tHPO7hI5FBxcX-jFnxEuUE9K' #-- Updated File ID for my zip
  downloaded = drive.CreateFile({'id': file_id})
  #print('Downloaded content "{}"'.format(downloaded.GetContentString(encoding='cp862')))
  </code></pre>
  
  <p>But I have to extract and store it in a separate directory as it would be easier for processing (as well as for understanding) of the dataset.</p>
  
  <p>I tried to extract it further, but getting "Not a zipfile error"</p>
  
  <pre><code>dataset = io.BytesIO(downloaded.encode('cp862'))
  zip_ref = zipfile.ZipFile(dataset, "r")
  zip_ref.extractall()
  zip_ref.close()
  </code></pre>

  <p>Note: Dataset is just for reference, I have already downloaded this zip to my google drive, and I'm referring to file in my drive only.</p>
