title: import cloudstorage, SyntaxError: invalid syntax
body: <p>I would like to use <a href="https://cloud.google.com/appengine/docs/standard/python/googlecloudstorageclient/functions" rel="noreferrer">Google Cloud Storage Client Library Functions</a>. </p>
  
  <p>For that I have to <code>import cloudstorage</code>. To get the <code>cloudstorage</code> I download <a href="https://cloud.google.com/appengine/docs/standard/python/googlecloudstorageclient/setting-up-cloud-storage" rel="noreferrer">Google Cloud Storage client library</a>. </p>
  
  <p>I try to import <code>cloudstorage</code> using <code>python -c "import cloudstorage"</code>. 
  I get the following error:</p>
  
  <pre><code>Traceback (most recent call last):
    File "&lt;string&gt;", line 1, in &lt;module&gt;
    File "/Users/fghavamian/Documents/PhD_work/Codes/python/convnet_gcloud/cloudstorage/__init__.py", line 20, in &lt;module&gt;

  SyntaxError: invalid syntax
  </code></pre>
  
  <p>Am I missing something? </p>
