title: How to remove first 4 bytes from s string in python
body: <p>I got a special packet in string format, which has 32 bytes header and the body contains one of more entries, each consist of 90 bytes.</p>
  
  <p>I want to process this string using python. Can I just read like sock read first 32 bytes header,  and take it off the string, and continue read 90 bytes of the first entry?</p>
  
  <p>something like:</p>
  
  <pre><code>str.read(32) # =&gt; "x01x02..."
  str.read(90) # =&gt; "x02x05..."
  </code></pre>
