title: python how to intentionally leave indented line blank?
body: <pre><code>for line in sys.stdin:
      line = line.strip()
      uid, profile = line.split('\t')
      try:
          process(profile)
      except:
          # do nothing and skip this profile
  </code></pre>
  
  <p>I would like to skip all profiles that throw exceptions. But python gives me</p>
  
  <pre><code>IndentationError: expected an indented block
  </code></pre>
  
  <p>at the line "# do nothing and skip this profile".</p>
  
  <p>How do I tell python to do nothing?</p>
