title: How to use the -c flag in python
body: <p>I noticed in the python doc that there is a <code>-c</code> flag. Here is what python doc says:</p>
  
  <blockquote>
    <p>Execute the Python code in <em>command</em>. <em>command</em> can be one or more
    statements separated by newlines, with significant leading whitespace
    as in normal module code.</p>
  </blockquote>
  
  <p>There is no example in the doc and I couldn't figure out how to make this work, and also in what situations it may help.</p>
  
  <p>Anyone have any clue?</p>
