title: Write out file with google colab
body: <p>Was there a way to write out files with google colab?
  For example, if I use</p>
  
  <pre><code>import requests
  r = requests.get(url)
  </code></pre>
  
  <p>Where will those files be stored? Can they be found?
  And similarly, can I get the file I outputted via say tensorflow save function</p>
  
  <pre><code>saver=tf.Saver(....)
  ...
  path = saver.save(sess, "./my_model.ckpt")
  </code></pre>
  
  <p>Thanks!</p>
