Gremlin-Python (GLV)
§ Directly incorporated and tested by Apache TinkerPop
§ Implements core pieces found in Gremlin-Java
– Graph Traversal
– Graph Traversal Source
– __
§ Install via pip package manager
§ Gremlin-Python sugar
– g.V().both()[1:3].toList()
– g.V().both().name.toList()
§ Bindings
– g.V(('id',4)).out('created').name.toList()

Report
Gremlin, the graph traversal language from Apache TinkerPop, continues to evolve in support of the growing graph ecosystem. In this session, we'll take a deep dive into Gremlin Language Variants (GLV) to see how TinkerPop enables modern programming languages to leverage Gremlin natively. By converting Gremlin into bytecode, the same instructions can be transmitted and interpreted by graph systems from different vendors. We'll uncover the benefits of this approach by demonstrating a Python-based graph architecture built to empower your application developers and data scientists. By using popular packages from Python open source, like Flask microframework and Jupyter notebooks, we'll see how you can easily transition your app development from your machine to the IBM Cloud. Presented at Graph Day SF on June 17, 2017.
