title: python 3.5.0 ::: Int() attributes
body: <p>Can anyone help studying these attributes that belong to the <code>int()</code> function:
  Example : When you call a variable and add an attribute thats in the directory of the <code>int()</code> function:</p>
  
  <pre><code>a = 5
  print (a.bit_length())
  </code></pre>
  
  <blockquote>
    <p>2</p>
  </blockquote>
  
  <p>What does the bit_length() atribute do to the variable? And I want to know the rest of them</p>
  
  <ul>
  <li>bit_length</li>
  <li>conjugate</li>
  <li>denominator</li>
  <li>from_bytes</li>
  <li>imag</li>
  <li>numerator</li>
  <li>real</li>
  <li>to_bytes </li>
  </ul>
  
  <p>I don't understand their use. Can you give me some examples?</p>
