Hi guys,
i try a simple query with py2neo an Cypher, (just install this
lib .. )  that's all :

			graph_db = neo4j.GraphDatabaseService(adprotocol+"://"+adserver
+":"+adport+addata)
			# Build a Cypher query
			query = "START me=node("+callingUser+") MATCH me-[:friendOf]->b
RETURN b.id,b.name"

			# Define a row handler...
			def print_row(row):
				b = row
				print(str(b["id_node"])+" "+b["name"])

			# ...and execute the query
			cypher.execute(query, graph_db, row_handler=print_row)

but server return me and error :

cypher.execute(query, graph_db, row_handler=print_row)\n', '  File "/
usr/local/lib/python2.7/dist-packages/py2neo-1.2.0-py2.7.egg/py2neo/

\n    raise IOError("Cannot send {0} request".format(method))\n',

Thank you for response Nigel :D

ps. i install the py2neo with easy_install, maybe the examples on web
site are older than code release/version, i think something like
streaming callback parameter.. :)
