title: How to create a simple class Queue in python 3.6?
body: <p>I'm beginner. Here is my code:</p>
  
  <pre><code>class Queue: 
      def __init__(self):
          self.queue = []
      def dequeue(self):
          self.queue.pop(O) 
      def enqueue(self,element):
          self.queue.append(element)
  q=Queue()
  q.enqueue('dog')
  print(q)
  </code></pre>
  
  <p>But! I see this:</p>
  
  <pre><code>&lt;__main__.Queue object at 0x00A3FC10&gt;
  </code></pre>
  
  <p>What is it? How to create this class than?</p>
