Neo4j Bolt driver for Python
Project description
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)
