neo4j-driver 1.6.0

Neo4j Bolt driver for Python

The Official Neo4j Driver for Python supports Neo4j 3.0 and above and Python versions 2.7, 3.4, 3.5 and 3.6.

Quick Example

from neo4j.v1 import GraphDatabase

driver = GraphDatabase.driver("bolt://localhost:7687", auth=("neo4j", "password"))

def add_friends(tx, name, friend_name):
    tx.run("MERGE (a:Person {name: $name}) "
           "MERGE (a)-[:KNOWS]->(friend:Person {name: $friend_name})",
           name=name, friend_name=friend_name)

def print_friends(tx, name):
    for record in tx.run("MATCH (a:Person)-[:KNOWS]->(friend) WHERE a.name = $name "
                         "RETURN friend.name ORDER BY friend.name", name=name):
        print(record["friend.name"])

with driver.session() as session:
    session.write_transaction(add_friends, "Arthur", "Guinevere")
    session.write_transaction(add_friends, "Arthur", "Lancelot")
    session.write_transaction(add_friends, "Arthur", "Merlin")
    session.read_transaction(print_friends, "Arthur")

The driver provides a built-in logging. The following example code enables debug logging and prints out logs at stdout:

from neo4j.util import watch

from sys import stdout

watch("neo4j.bolt", logging.DEBUG, stdout)
