title: Query regarding Python Multiple Regex Expression
body: <p>I am new to Python, just trying to solve a few regex expressions, I was stuck with the below code. Kindly help me out on this.</p>
  <pre class="lang-py prettyprint-override"><code>import re
  a = [&quot;my mac is aa-bb-cc-33-44-SS&quot;,&quot;Hostname: xyz1&quot;]
  for i in a:
      c = re.findall(r&quot;\\D{2}-\\D{2}-\\D{2}-\\d{2}-\\d{2}-\\D{2}|:(.\*)&quot;,i)
      print(c)
  </code></pre>
  <p>Output for above code is :
  ['']
  [' xyz1']</p>
  <p>But the output really needed is
  ['aa-bb-cc-33-44-SS']
  ['xyz1]</p>
