title: Create Pandas DataFrame from a string
body: <p>In order to test some functionality I would like to create a <code>DataFrame</code> from a string. Let's say my test data looks like:</p>
  
  <pre><code>TESTDATA="""col1;col2;col3
  1;4.4;99
  2;4.5;200
  3;4.7;65
  4;3.2;140
  """
  </code></pre>
  
  <p>What is the simplest way to read that data into a Pandas <code>DataFrame</code>?</p>
