title: Regex expression finding digits from a string
body: <p>I have the following string which I need to get the number '4' from the string to use it for further use in the code:</p>
  <pre><code>   1 IDM  485556     4     427   RUN  0 ===== Not set =====  unknown
  </code></pre>
  <p>It occurs twice in the string but both conveys the same message. Please can someone help me with an easy way to search for that digit using python regex</p>
