Nice! is there a way to run it easily from python with neo4jrestclient, avoiding creating an http request manually ? In general, I wasn't able to understand how to run a Gremlin script, or just a query, in python through the restclient library. Probably is a very simple business, but I started using it in Python just yesterday.
