title: Read certain part of string from file
body: <p>Trying python after a very long time now.</p>
  
  <p>I have a file that has a line:</p>
  
  <pre><code>My_NUMBER                 =  24
  </code></pre>
  
  <p>I want to extract this number ( here I have assumed 24 but this is something I want to extract based on My_NUMBER.In my python code I am able to read the line </p>
  
  <pre><code>with open(filename) as f: lines = f.read().splitlines()
  
  for line in lines:
      if line.startswith(' My_NUMBER                 ='):
          line=(line.rsplit(' ', 1)[0])
          num= line.rsplit('=',1)[1].split("=")[0]
          num = num.strip(" ")
          print num
  </code></pre>
  
  <p>However this does print blank output and not the number. Can anyone commet in case I am doing anything obviously wrong here?</p>
