Python - connecting to Neptune using gremlin

Question

I am trying to connect to Neptune using Python from EC2 instance.

Python code:

from __future__  import print_function  # Python 2/3 compatibility

from gremlin_python import statics
from gremlin_python.structure.graph import Graph
from gremlin_python.process.graph_traversal import __
from gremlin_python.process.strategies import *
from gremlin_python.driver.driver_remote_connection import DriverRemoteConnection

graph = Graph()

remoteConn = DriverRemoteConnection('wss://my_end_point:8182/gremlin','g')
g = graph.traversal().withRemote(remoteConn)

print(g.V().has("system.tenantId", "sample_tenantId").count())
remoteConn.close()

rather than executing gremlin query . its giving output as it is

output: [['V'], ['has', 'system.tenantId', 'sample_tenantId'], ['count']]

question: why its not taking gremlin query?

Please note: Connection is proper and I got output as mentioned in the link: https://docs.aws.amazon.com/neptune/latest/userguide/access-graph-gremlin-python.html

output: [v[sample_RETURN_D_H], v[sample_IND]]
