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")Logging
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
import logging
from sys import stdout
watch("neo4j.bolt", logging.DEBUG, stdout)Installation
