title: Pandas data from stdin
body: <p>Is it possible to have stdin data go into a pandas DataFrame?</p>
  
  <p>Currently I'm saving the data in an intermediate <code>json</code> file and then doing:</p>
  
  <pre><code>pandas.read_json('my_json_file.json')
  </code></pre>
  
  <p>but was wondering if it's possible to pipe the stdin directly in the python script.
  I found this: <a href="https://stackoverflow.com/questions/2264991/how-to-read-from-stdin-or-from-a-file-if-no-data-is-piped-in-python">How to read from stdin or from a file if no data is piped in Python?</a>
  but not sure how to do a line-by-line insertion in a pandas DF.</p>
