title: What does request.GET.get mean?
body: <p>What does request.GET.get mean? I see something like this in Django</p>
  
  <pre><code>page = request.GET.get('page', 1)
  </code></pre>
  
  <p>which I think is connected to something like</p>
  
  <pre><code>&lt;li&gt;&lt;a href="?page={{ users.previous_page_number }}"&gt;&amp;laquo;&lt;/a&gt;&lt;/li&gt;
  </code></pre>
  
  <p>How do they work?</p>
