This repository contains the official Neo4j driver for Python. Each driver release (from 4.0 upwards) is built specifically to work with a corresponding Neo4j release, i.e. that with the same major.minor version number. These drivers will also be compatible with the previous Neo4j release, although new server features will not be available.
Python 3.4 or above is required. Python 2 support has been dropped as of the Neo4j 4.0 release.
To install the latest stable version, use:
pip install neo4jfrom neo4j import GraphDatabase
driver = GraphDatabase.driver("bolt://localhost:7687", auth=("neo4j", "password"))
def add_friend(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_friend, "Arthur", "Guinevere")
session.write_transaction(add_friend, "Arthur", "Lancelot")
session.write_transaction(add_friend, "Arthur", "Merlin")
session.read_transaction(print_friends, "Arthur")
