To add to what Michael said, your call to py2Neo would look like the
following.
merge_query = "MATCH (fist:Person), (second:Person) WHERE first.name IN
{names1} and second.names IN {names2} MERGE (first)-[r:KNOWS]-(second) RETURN
r;"
*graph.cypher.execute(merge_query, {name1: "name1_value", name2:
"name2_value"})*
Where graph is an instance of the Graph class in py2neo.
