title: how to call python script in kettle
body: <p>I have a problem in <code>kettle</code> connecting <code>python</code>. In <code>kettle</code>, I only find the <code>js</code> script module.</p>
  <p>Does kettle support python directly? I mean, can I call a python script in <code>kettle</code> without using <code>js</code> or others?</p>
  <p>By the way, I want to move data from <code>Oracle</code> to <code>Mongo</code> regularly. I choose to use <code>python</code> to implement the transformation. So without external files, does it have some easy methods to keep the synchronization between a relational db and a no-rdb?</p>
  <p>Thanks a lot.</p>
