title: How can I send a data array back and forth between java and python?
body: <p>I have a java program and I need it to get some data calculated by a python script. </p>
  
  <p>I've already got java to send an integer to python via jython's PythonInterpreter and displayed it, but I can't recover it to make other operations. Also, it would be great to send a full integer array rather than a single integer but I can't wrap my mind arround PyObjects and how to use them.</p>
  
  <p>Is there any useful tutorial that covers arrays? I've been searching for a while but I just find integer and float related tutorials.</p>
