title: Python Regex : find next 5 alphabets
body: <p>I have a string like <code>"SW: C000032345RE"</code>. I am trying to extract next 10 alphabets. </p>
  
  <p>So the answer should be like <code>"C000032345RE"</code>. I am trying to achieve it with two different methods </p>
  
  <p>Fist is next 10 alphabets after SW: or the alphabets between SW: and RE. I am using following script</p>
  
  <pre><code>import re 
  sub = "SW: C000032345RE"
  a= re.search("^SW: (\w)", sub)
  a.group(0)
  </code></pre>
  
  <p>of course its not showing me desired results. Every help is important!</p>
