+Sample Traversals
+-----------------
+
+The Gremlin language allows users to write highly expressive graph traversals
and has a broad list of functions that
+cover a wide body of features. The `Reference Documentation
<https://tinkerpop.apache.org/docs/current/reference/#graph-traversal-steps>`_
+describes these functions and other aspects of the TinkerPop ecosystem
including some specifics on
+`Gremlin in Python
<https://tinkerpop.apache.org/docs/current/reference/#gremlin-python>`_ itself.
Most of the
+examples found in the documentation use Groovy language syntax in the
+`Gremlin Console
<https://tinkerpop.apache.org/docs/current/tutorials/the-gremlin-console/>`_.
+For the most part, these examples should generally translate to Python with
+`some modification
<https://tinkerpop.apache.org/docs/current/reference/#gremlin-python-differences>`_.
Given the
+strong correspondence between canonical Gremlin in Java and its variants like
Python, there is a limited amount of
+Python-specific documentation and examples. This strong correspondence among
variants ensures that the general
+Gremlin reference documentation is applicable to all variants and that users
moving between development languages can
+easily adopt the Gremlin variant for that language.

+Create Vertex
+^^^^^^^^^^^^^
+
+.. code:: python
+
+ from gremlin_python.process.traversal import T
+ from gremlin_python.process.traversal import Cardinality
+
+ id = T.id
+ single = Cardinality.single
+
+ def create_vertex(self, vid, vlabel):
+ g.addV(vlabel).property(id, vid). \
+ property(single, 'name', 'Apache'). \
+ property('lastname', 'Tinkerpop'). \ # default database cardinality
