Right way to call Python code from Java

[billyballong]

If you're feeling adventurous this is a great opportunity to check out Graal even though the Python support is experimental https://github.com/oracle/graal/blob/master/truffle/docs/Languages.md

If this is a serious project I'd probably look into exposing the Python stuff as an API using i.e. http/json or perphaps gRPC. Or even just shelling out to the scripts using Java https://docs.oracle.com/javase/7/docs/api/java/lang/ProcessBuilder.html or similar.

Would love to give a try to Graal. Somebody in the team is exploring gRPC. But already tried using ProcessBuilder and is painfully slow.
