python: what is the purpose of using ( ) in python imports?
<p>I just saw the following</p>

<pre><code>from flask_login import (LoginManager, login_required, login_user, 
                         current_user, logout_user, UserMixin)
</code></pre>

<p>in <a href="http://blog.thecircuitnerd.com/flask-login-tokens/">here</a></p>

<p>What is the purpose of using parenthesis <code>()</code> in import statement?</p>

<p>Why shall someone use parenthesis while we can live without it?  </p>

<p>is it recommended?</p>
