Neo4j Bolt driver for Python

Project description

This repository contains the official Neo4j driver for Python.

Starting with 5.0, the Neo4j Drivers will be moving to a monthly release cadence. A minor version will be released on the last Friday of each month so as to maintain versioning consistency with the core product (Neo4j DBMS) which has also moved to a monthly cadence.

As a policy, patch versions will not be released except on rare occasions. Bug fixes and updates will go into the latest minor version and users should upgrade to that. Driver upgrades within a major version will never contain breaking API changes.

Quick Example

from neo4j import GraphDatabase, RoutingControl


URI = "neo4j://localhost:7687"
AUTH = ("neo4j", "password")


def add_friend(driver, name, friend_name):
    driver.execute_query(
        "MERGE (a:Person {name: $name}) "
        "MERGE (friend:Person {name: $friend_name}) "
        "MERGE (a)-[:KNOWS]->(friend)",
        name=name, friend_name=friend_name, database_="neo4j",
    )


def print_friends(driver, name):
    records, _, _ = driver.execute_query(
        "MATCH (a:Person)-[:KNOWS]->(friend) WHERE a.name = $name "
        "RETURN friend.name ORDER BY friend.name",
        name=name, database_="neo4j", routing_=RoutingControl.READ,
    )
    for record in records:
        print(record["friend.name"])


with GraphDatabase.driver(URI, auth=AUTH) as driver:
    add_friend(driver, "Arthur", "Guinevere")
    add_friend(driver, "Arthur", "Lancelot")
    add_friend(driver, "Arthur", "Merlin")
    print_friends(driver, "Arthur")
