The following code :

  1: def handle_row(row):
  2:     print ("cypher query result:")
  3:     print ( len (row))
  4:     for nextNode in row:
  5:         print (nextNode)
  6:         print (type(nextNode))
  7: 
  8: 
  9: theCyperCode = "START n=node(1) ,other=node(2, 3)  RETURN  n,other"
 10: 
 11: cypher.execute(graph_db, theCyperCode, row_handler=handle_row)

returns
cypher query result:
2
(1 {"name":"Bruce Willis"})
<class 'py2neo.neo4j.Node'>
(2 {"name":"John McClane"})
<class 'py2neo.neo4j.Node'>
cypher query result:

(1 {"name":"Bruce Willis"})
<class 'py2neo.neo4j.Node'>
