我写了一个带有灯泡的python客户端,如下所示
__author__ = 'rponnapureddy'
from bulbs.config import Config, DEBUG
from bulbs.rexster import Graph
from bulbs.rexster import Graph
# config = Config('http://localhost:8182/graphs/empgraph')
config = Config('http://localhost:8182/graphs/ramgraph')
g = Graph(config)
class inser_class():
ponnapu = g.vertices.create(name="ramnath")
pr = g.vertices.create(name="reddy")
tanu = g.vertices.create(name="brothers")
g.edges.create(pr, "knows", tanu)
# z=g.get_graphml()
#print z
#g.clear()
# print z
我得到了以下错误。要纠正我的所作答案?
