title: Python - How to remove/unimport libs was imported before
body: <p>As we know that, in python 2.x, if we divide two integer values it results in an <code>int</code>. However, if using <code>from __future__ import division</code>, we instead get a <code>float</code> value.</p>
  
  <pre><code>&gt;&gt;&gt; 3/2
  1
  &gt;&gt;&gt; from __future__ import division
  &gt;&gt;&gt; 3/2
  1.5
  &gt;&gt;&gt; 
  &gt;&gt;&gt; 
  &gt;&gt;&gt; 3//2
  1
  &gt;&gt;&gt; 4/3
  1.3333333333333333
  &gt;&gt;&gt; 
  </code></pre>
  
  <p>So, <code>//</code> instead of <code>/</code> should be used if we want integers after importing <code>__future__.division</code>, but I want to know how to make <code>/</code> to return integers again.</p>
  
  <p>Is there any way to un-import or remove the previously imported module?</p>
  
  <hr>
  
  <p>There is a method to unimport libs or Modules in IDLE, that is to <strong>Restart it</strong> by using Ctrl+F6 or Options in Menu</p>
