title: Adding '0' to binary
body: <p>How can i add number of '0' values to the left side of an existing binary type?</p>
  
  <p>im getting the binary type by using the following:</p>
  
  <pre><code> binary=bin(int(symbol))
  </code></pre>
  
  <p>where <code>symbol</code> is an int.</p>
  
  <p>is there any way of doing that?</p>
  
  <p>i want the result to be a string.</p>
