title: How can I transform a file to bits?
body: <p>So I need to transform a file to bits and manipulate them 4 by 4. I'm currently starting in Python so I don't know how to do this. I currently have:</p>
  
  <pre><code>    fbi=open(route, "rb")
      fbi=fbi.read()
      print(fbi)
  </code></pre>
  
  <p>And I get something alike to hex values, except for some times, where I get things like " x0f|U+] " or "xd0F" and "x83*".</p>
  
  <p>Can someone really explain to me how to get the bits, and also what I'm seing when I print fbi ?
  Thanks in advance</p>
